3′ × 5 Vertical Electronics Workspace

There’s a great deal of innovative electronics engineering and embedded systems development taking place in Europe. The Circuit Cellar team reviews dozens of inventive projects and insightful articles from European engineers each year. And based on the quality of that content, we’re convinced that Europe’s electrical engineers, programmers, and embedded designers are among the most industrious, inspired, and creative tech specialists in the world.

Burghausen, Germany-based Hubert Wihr is one of the many Europeans actively designing interesting electronic systems in his free time. At about 3′ × 5′ (approximately 90 cm × 150 cm), his workspace doesn’t leave much room for expansion or the addition of too many new design tools. But as long as at Wihr enjoys the space and finds it suitable, he gets the thumbs up from our staff.

WihrVerticalWorkspace

Hubert Wihr’s 3′ × 5′ workspace

We applaud his intelligent use of vertical space. Like an architect trying to add office space to a cramped city block, Wihr simply built upward. He effectively installed a few feet of vertical shelving and storage space to accommodate his PC, soldering station, test equipment, parts, and a perfectly placed cork board for tacking handwritten notes.

As for Wihr’s neatly labeled parts containers, well, you know how we feel about those. Such a storage system is an essential part of every proper workspace. If you look closely at his labels, you can see he’s storing Schraube (screws), Haken (hooks), and more.

Lastly, Wihr has a simple yet effective solution for keeping his tools in order and readily available. He smartly mounted his peripheral cables within arm’s reach to the right of his monitor. And just left of his cork board he hangs pliers, wire cutters, and a few other frequently used tools. Nice idea.

The 100% Creative Workspace

Bernard Hiew sure knows how to get the most of his Penang, Malaysia-based “humble” electrical engineering workspace. He turned the third room of his apartment into a complete innovation space that’s used for everything from engineering to 3-D printing to playing music to woodworking.

Hiew's workspace features component storage, a soldering station, power supply, and more

Hiew noted:

I spend my most of my time here, my little humble workspace. This room is not a dedicated workshop at somewhere else but is in my house. Half of the room is my workspace … The other half of the room is the main table where we do most of office work and surfing. Recently my wife is working from home, so she is occupying this table most of the time.

To the right of his main engineering space is a bookcase and additional shelving

Hiew proves that with a little planning and ingenuity, you can create a fully functional workspace complete with essential engineering equipment and tools. His space includes a soldering station, a PCB UV box, multimeter, power station, computer, book shelves, and even a couch for relaxing and playing music. He also makes great use of storage containers for his electrical components.

Electronics “Mancave”: Small-Footprint Workspace

When it comes to a workspace, more doesn’t necessarily mean better. We encourage engineers and DIYers to focus their time and money on engineering, not on acquiring new and used equipment they’ll never use.

Belgium-based Jan Cumps has a very basic yet effective workspace. It is a true workspace. That means he actually has room to work there. It isn’t a cluttered room for storing junk.

Cumps noted:

I’m a clean-desker. Have to share it with studying kids. All gear has to have small footprint, or must be stow-away-able. That’s why you see a 4-in-1 multimeter, power supply, frequency counter and function generator, and a 2-in-1 hot air plus solder station. Components, meters, cables and what have you are stowed a way in boxes.

One Professor and Two Orderly Labs

Professor Wolfgang Matthes has taught microcontroller design, computer architecture, and electronics (both digital and analog) at the University of Applied Sciences in Dortmund, Germany, since 1992. He has developed peripheral subsystems for mainframe computers and conducted research related to special-purpose and universal computer architectures for the past 25 years.

When asked to share a description and images of his workspace with Circuit Cellar, he stressed that there are two labs to consider: the one at the University of Applied Sciences and Arts and the other in his home basement.

Here is what he had to say about the two labs and their equipment:

In both labs, rather conventional equipment is used. My regular duties are essentially concerned  with basic student education and hands-on training. Obviously, one does not need top-notch equipment for such comparatively humble purposes.

Student workplaces in the Dortmund lab are equipped for basic training in analog electronics.

Student workplaces in the Dortmund lab are equipped for basic training in analog electronics.

In adjacent rooms at the Dortmund lab, students pursue their own projects, working with soldering irons, screwdrivers, drills,  and other tools. Hence, these rooms are  occasionally called the blacksmith’s shop. Here two such workplaces are shown.

Oscilloscopes, function generators, multimeters, and power supplies are of an intermediate price range. I am fond of analog scopes, because they don’t lie. I wonder why neither well-established suppliers nor entrepreneurs see a business opportunity in offering quality analog scopes, something that could be likened to Rolex watches or Leica analog cameras.

The orderly lab at home is shown here.

Matthes prefers to build his  projects so that they are mechanically sturdy. So his lab is equipped appropriately.

Matthes prefers to build mechanically sturdy projects. So his lab is appropriately equipped.

Matthes, whose research interests include advanced computer architecture and embedded systems design, pursues a variety of projects in his workspace. He describes some of what goes on in his lab:

The projects comprise microcontroller hardware and software, analog and digital circuitry, and personal computers.

Personal computer projects are concerned with embedded systems, hardware add-ons, interfaces, and equipment for troubleshooting. For writing software, I prefer PowerBASIC. Those compilers generate executables, which run efficiently and show a small footprint. Besides, they allow for directly accessing the Windows API and switching to Assembler coding, if necessary.

Microcontroller software is done in Assembler and, if required, in C or BASIC (BASCOM). As the programming language of the toughest of the tough, Assembler comes second after wire [i.e., the soldering iron].

My research interests are directed at computer architecture, instruction sets, hardware, and interfaces between hardware and software. To pursue appropriate projects, programming at the machine level is mandatory. In student education, introductory courses begin with the basics of computer architecture and machine-level programming. However, Assembler programming is only taught at a level that is deemed necessary to understand the inner workings of the machine and to write small time-critical routines. The more sophisticated application programming is usually done in C.

Real work is shown here at the digital analog computer—bring-up and debugging of the master controller board. Each of the six microcontrollers is connected to a general-purpose human-interface module.

Workspace for Precision Design

Brad Boegler is a do-it-yourselfer’s DIYer. His West Bloomfield, MI-based workspace is something to admire. It features a sturdy 8’ × 5’ workbench, a well-built machining bench, and dozens of handy tools that enable him to work on projects ranging from constructing a temperature-monitoring network to milling custom heatsinks. Simply put, it’s an appealing space for any innovator interested in DIY electronics and machining projects.

Photo 1: One of Boegler’s Altera CPLD breakout boards is on the bench. He said he was “experimenting with some video generators in VHDL” when he took this picture. (Source: B. Boegler)

As I reviewed Boegler’s space, the same word kept popping into my mind: precision. Why? Let’s see.

Building a bench (or benches) for a workspace like Boegler’s takes a lot of precision measuring, cutting, fitting, and constructing. Check out the workbench in Photo 1. That’s no “Ikea hack.” The 8’ × 5’ bench fits a dual monitor setup, plenty of test/measurement equipment, a solder station, and more.

Boegler—who works as Linux sysadmin—described some of the equipment on this bench via email:

The left side of the bench is mostly RF equipment: there are two HP RF frequency generators, a VNA, and spectrum analyzer. The analog scope is a Tek 2246 and is one of my favorite scopes. Next to that is an HP 16500B logic analysis system and then a HP 54112D digital scope … The bench was custom made. I was not able to find any benches to my liking so I ended up building my own. It is 8′ wide by 5′ deep and constructed out of mostly 4×4s. It weighs a ton, but it has to be sturdy as a lot of this equipment is very heavy. I like very deep benches as I can push the equipment back far enough on it and still provide enough working space.

And don’t forget the power!

Those are various adjustable voltage current limiting power supplies, when working on projects needing various voltages you can never have too many supplies.

I’m sure everyone agrees that access to power supplies is key.

Photo 2: Boegler’s workspace for machining (Source: B. Boegler)

On a separate bench (Photo 2) are Boegler’s milling machine and drill press, which are two tools intended for precision designing and machining. Boegler wrote:

The drill press is used almost daily, one of the best tools ever. I use the milling machine for custom shielded aluminum cases for RF boards, making special sized heatsinks, and it comes in handy for any special brackets I can make to hold boards or components.

I’m sure you’d agree that machining board cases and heatsinks requires a bit of exactitude.

Much like the bench in Photo 1, building the actual machine bench required precise measurements and cuts. Just look at its clean edges and sturdy frame. And don’t you like the shelf underneath? It’s a simple yet effective place for stowing frequently used tools.

On the topic of storage, check out Boegler’s wheeled shelf system. I like it and will consider something similar for my garage. (We all take wheels for granted until we’re in a pinch and need to move a heavy object. For instance, try moving a wheel-less six-shelf system full of parts in order to track down a screw that fell on the floor. Actually, don’t try that. It’s an accident waiting to happen.)

Lastly, check out the neatly labeled parts boxes. I see labels such as “Microcontrollers/DSP,” “Op-Amps,” “Serial Cables,” and more. Nice!

Cabinet-Based DIY Electronics Workspace

Micrcontrollers and electrical engineering probably don’t come to mind when you flip through an IKEA product catalog. But when you think about it, IKEA has plenty of easy-to-assemble tables, cabinets, and storage containers that could be handy for outfitting a electronics workspace or “circuit cellar.”

(Source: Patrik Thalin)

(Source: Patrik Thalin)

Sweden-based Patrik Thalin built a workspace within an IKEA Husar cabinet. The setup is compact, orderly, and well-planned. He noted:

It has a pull-out keyboard shelf that I use it as an extension of the workspace when the doors are open. My inspiration came from a friend that had built his lab in a two door closet. The main idea is to have a workspace that can be closed when not used and to be able to resume my work later. I have used this lab for nearly ten years and I am still happy with it!

In the upper part of the cabinet I keep commonly used tools and instruments. On the top shelf are two PSUs, a signal generator, assortment boxes with components, the SMD component kit and shelf trays with cables and small tools. On the lower shelves are things like multimeter, callipers and a power drill. At the bottom is the work space with a soldering station. On the left wall are screwdrivers,wrenches and pliers. To the left are cables hanging on hooks.The thing hanging under the shelf is an old radio scanner. You can also see a small vise hanging on the front of the workspace.

The lower part of the cabinet is for additional storage, he noted.

System Engineer’s Space for Designing & Testing

Many complicated motion control and power electronics systems comprise thousands of parts and dozens of embedded systems. Thus, it makes sense that a systems engineer like New Jersey-based John Roselle would have more than one workspace for simultaneously planning, designing, and testing multiple systems.

(Source: John Roselle)

Roselle recently submitted images of his space and provided some interesting feedback when we asked him about it.

My main work space for testing and debugging of circuits consists of nothing more than a kitchen table with two shelves attached to the wall.  Shown in the picture (see above) a 265-V digital motor drive for a fin control system for an under water application.  In a second room I have a computer design center.

I design and test mostly motor drives for motion control products for various applications, such as underwater vehicles, missile hatch door motor drives, and test equipment for testing the products I design.

John’s third workspace is used mainly for testing and assembling. At times there might be two or three different projects going on at once, he added.

Professor’s Convertible Electronics Workspace

In addition to serving as a contributor and technical reviewer for Circuit Cellar, Chris Coulston heads the Computer Science and Software Engineering department at Penn State Erie, The Behrend College. He has a broad range of technical interests, including embedded systems, computer graphics algorithms, and sensor design.

Since 2005, he has submitted five articles for publication in Circuit Cellar, on projects and topics ranging from DIY motion-controlled gaming to a design for a “smart” jewelry pendant utilizing RGB LEDs.

We asked him to share photos and a description of the workspace in his Erie, PA, home. His office desk (see Photo 1) has something of an alter ego. When need and invention arise, he reconfigures it into an “embedded workstation.”

Coulston's workspace configured as an office desk

Photo 1: Coulston’s workspace configured as an office desk

When working on my projects, my embedded workstation contains only the essential equipment that I need to complete my project (see Photo 2).  What it lacks in quantity I’ve tried to make up for in quality instrumentation; a Tektronix TDS 3012B oscilloscope, a Fluke 87-V digital multimeter, and a Weller WS40 soldering iron.  While my workstation lacks a function generator and power supply, most of my projects are digital and have modest power requirements.

Coulston can reconfigure his desk into the embedded workstation pictured here.

Photo 2: Coulston can reconfigure his desk into the embedded workstation pictured here.

Coulston says his workspace must function as a “typical office desk” 80 percent of the time and electronics station 20 percent of the time.

It must do this while maintaining some semblance of being presentable—my wife shares a desk in the same space. The foundation of my workstation is a recycled desk with a heavy plywood backing on which I attached shelving. Being a bit clumsy, I’ve tried to screw down anything that could be knocked over—speakers, lights, bulletin board, power strip, cable modem, and routers.

The head of a university department has different needs in a workspace than does an electronics designer. So how does Coulston make his single office desk suffice for both his professional and personal interests? It’s definitely not a messy solution.

My role as department chair and professor means that I spend a lot time grading, writing, and planning. For this work, there is no substitute for uncluttered square footage—getting all the equipment off the working surface. However, when it’s time to play with the circuits, I need to easily reconfigure this space.

I have found organization to be key to successfully realize this goal. Common parts are organized in a parts case, parts for each project are put in their own bag, the active project is stored in the top draw, frequently used tools, jumper wires, and DMM are stored in the next draw. All other equipment is stored in a nearby closet.

I’ve looked at some of the professional-looking workspaces in Circuit Cellar and must admit that I am a bit jealous. However, when it comes to operating under the constraints of a busy professional life, I have found that my reconfigurable space is a practical compromise.

Engineer’s Transformable Workspace

No two workspaces or circuit cellars are alike. And that’s what makes studying these submissions so fascinating. Each space reflects the worker’s interests, needs, and personality.

Succasunna, NJ-based Mike Sydor’s penchant for “hacking” isn’t relegated solely to electronics. His entire workspace is actually a hack designed for both hardware and software projects. It’s an excellent example of what you can do with a little creativity and planning!

When the front is open, Mike can tackle hardware projects (Source: Mike Sydor)

We love the “transformer” theme that runs through the entire space. Simply put, the compact space is easily rearranged to serve Mike’s various needs:

  • When the front is closed, Mike can work on the “soft arts” of coding, diagramming, and design planning.
  • When the front is open, Mike has easy access to essential tools such as an oscilloscope, isolation transformer, and solder station.
  • A KVM switch enables Mike move back and forth between Linux and Windows

    Mike simply closes the front when he shifts from hardware mode to software mode (Source: Mike Sydor)

Another interesting point to note is that Mike can detach the shelf/drawer so the workspace can fit through a door if necessary. Great idea! Now he can take the workspace with him if he ever moves.

Submitted by Mike Sydor:

Here is my workspace for your consideration.  It is basically a custom, drop-front workspace on wheels so that I can move it easily to reconfigure the equipment or otherwise get to all the gear.  It has two configurations.  The ‘software’ setting (front closed) where I can focus on the code, design docs, etc.  The shelf can also hold a midi keyboard for music ‘hacking.’  There is a drawer in that shelf for miscellaneous items.  With the front open, you have a nice workspace for assembly and debugging, you can still access the drawer, and you can access all of the gear.  Everything is self-contained – only a single power and network cable are ‘on the floor.’  The shelf/drawer assembly detaches for moving day – otherwise it is too wide to fit through a standard door opening.  I also only use three wheels.  This makes a tripod, which is stable on any surface.  I live in an older home – no level floors! – so mobility does not compromise stability and I don’t have to shim one side or the other to keep it from wobbling.   The mass of all the gear keeps the bench stable.  The monitors are mounted on a custom stand so that they can be positioned, via swing arms and are otherwise stable when you need to move the bench around.  I use a KVM switch with multiple computers (windows, Linux) and have a set of cables so that I can plug in a project computer and use the same monitors and keyboard.  All the computers are on the same switch for optimal Ethernet performance.  I build kits, prototype circuits for sensor conditioning and muck around with micro-controllers, as well as fix/hack your various consumer electronics.  Cheers, Mike Sydor.

All the good stuff in one place! Power, a solder station, a scope, and more! (Source: Mike Sydor)

Birmingham-Based Electronics Design Nook

Steve Karg of Birmingham, AL, recently submitted info about his well-planned, cost-conscious design nook where he builds lighting control products, develops software, tests and debugs his projects, and more. The workspace is compact yet intelligently stocked with essentials such as a laptop, a scope, a toaster, a magnifier, a labelled parts bin, an AC source, and more.

Karg writes:

Here is a photo of my electronics workspace in my cellar. I use the toaster oven for soldering surface mount parts to printed circuit boards, the scope and meters for the usual diagnostics and validation, the AC source for developing line voltage dimming and switching lighting control products, the laptop for developing software including the open source BACnet Stack and Wireshark, and the light tent for deriving dimming curves for various lamps.  I bought the chairs and lab bench at a Martin-Marietta yard sale in Colorado, and they moved 3 times with me to Pennsylvania, Georgia, and now Alabama. I found the Metcal soldering iron in a dumpster in Maryland near an office building.—Steve Karg, Birmingham, AL

Steve Karg’s circut cellar in Birmingham, AL

In addition to placing his essential tools within reach, Karg did a few things we think every designer should consider when planning his or her workspace.

One, Karg neatly labelled the parts box located on the right side of the shelf above his workbench. Label now and you’ll thank yourself later.

Two, Karg has deep, sturdy, wall-mounted shelves above his workbench. As you can see, they’re capable of holding fairly large bins and boxes. They aren’t flimsy 8″ deep shelves intended for displaying lightweight curios or paperback books. If you’re planning a workspace, consider following Karg’s lead by installing sturdy shelving capable of holding everything from electronic equipment to every copy of Circuit Cellar since 1988.

Three, we applaud Karg’s magnification and lighting equipment. A cellar can be dark place, especially if it is completely underground and isn’t a “walkout” (or “daylight basement”) with a windowed door. Many basements have only a few small hopper windows that enable daylight and fresh air to get inside. In such spaces, darkness and shadows can be problematic for electrical engineers and electronics DIYers working on small projects. Without a properly placed light or lighting system, your body can overshadow your work. Good luck trying taking a close look at a board or attempting to repair a PCB trace without proper lighting. It’s clear Karg has proper lighting in mind. As you can see, he has plenty of lamps and light sources at his disposal.

And finally, kudos to Karg for purchasing the bench at a yard sale and staying with the discarded soldering iron he found in a dumpster. We all know the saying: “If ain’t broke, don’t fix it.” We agree, except when what’s broke is mounted on your circuit board, of course!

A Rat’s Nest-Less Workspace: Clean with Plenty of Screens

Two sorts of things we love to see in an electronics workspace: cleanliness and multiple monitors! San Antonio, TX-based Jorge Amodio’s L-shaped modular desk is great setup that gives him easy access to his projects, test equipment, and computers. The wires to all of his equipment are intelligently placed behind and below the workspace. Hence, no rat’s nest of wires! He doesn’t need to work on top of cords and peripherals like, well, a few of us do here in our office. We like how he “sectioned” his space to provide maximum multitasking capability. The setup enables him to move easily from doing R&D work to emailing to grabbing his iPhone without any more effort than a slide of his chair. Very nice.

Robotics, Hardware Interfacing, and Vintage Electronics

Gerry O’Brien, a Toronto-based robotics and electronics technician at R.O.V. Robotics, enjoys working on a variety of projects in his home lab. His projects are largely driven by his passion for electronics hardware interfacing.

Gerry’s background includes working at companies such as Allen-Vanguard Corp., which builds remotely operated vehicle (ROV) robots and unmanned ground vehicles (UGVs) for military and police bomb disposal units worldwide. “I was responsible for the production, repair, programming and calibration of the robot control consoles, VCU (vehicle control unit) and the wireless communication systems,” he says.

Gerry recently sent Circuit Cellar photos of his home-based electronics and robotics lab. (More images are available on his website.) This is how he describes the lab’s layout and equipment:

In my lab I have various designated areas with lab benches that I acquired from the closing of a local Nortel  R&D office over 10 years ago.

All of my electronics benches have ESD mats and ground wrist straps.  All of my testing gear, I have purchased on eBay over the years….

PCB flip rack

PCB flip-rack

To start, I have my “Electronics Interfacing Bench” with a PCB flip-rack , which allows me to Interface PCBs while they are powered (in-system testing). I am able to interface my Tektronix TLA715 logic analyzer and other various testing equipment to the boards under test. My logic analyzer currently has two  logic I/O modules that have 136 channels each. So combined, I have 272 channels for logic analysis. I also have a four-channel digital oscilloscope module to use with this machine. I can now expand this even further by interfacing my newly acquired expansion box, which allows me to interface many more modules to the logic analyzer mainframe.

My devoted robotics bench has several robotic arm units, Scorbot and CRS robots with their devoted controllers and pneumatic Interface control boards.

Robotics bench

Robotics bench and CRS robot

On my testing bench, I currently have an Agilent/HP 54610B 500-MHz oscilloscope with the GPIB to RS-232 adapter for image capturing. I also have an Advantest model R3131A 9 kHz to 3-GHz bandwidth spectrum analyzer, a Tektronix model AFG3021 function generator, HP/Agilent 34401A multimeter and an HP 4CH programmable power supply. For the HP power supply, I built a display panel with four separate voltage output LCD displays, so that I can monitor the voltages of all four outputs simultaneously. The stock monochrome LCD display on the HP unit itself is very small and dim and only shows one output at a time.

Anyhow, my current testing bench setup will allow me to perform various signal mapping and testing on chips with a large pin count, such as the older Altera MAX9000 208-pin CPLDs and many others that I enjoy working with.

The testing bench

And last but not least… I have my programming and interfacing bench devoted to VHDL programming, PCB Design, FPGA hardware programming (JTAG), memory programming (EEPROM  and flash memory), web design, and video editing.

Interfacing bench and "octo-display"

Interfacing bench and “octo-display”

I built a PC computer and by using  a separate graphics display cards, one being an older Matrols four-port SVGA display card; I was able to build a “octo-display” setup. It seamlessly shares eight monitors providing a total screen resolution size of 6,545 x 1,980 pixels.

If you care to see how my monitor mounting assembly was built, I have posted pictures of its construction here.

A passion for electronics interfacing drives Gerry’s work:

I love projects that involve hardware Interfacing.  My area of focus is on electronics hardware compared to software programming. Which is one of the reasons I have focused on VHDL programming (hardware description language) for FPGAs and CPLDs.

I leave the computer software programming of GUIs to others. I will usually team up with other hobbyists that have more of a Knack for the Software programming side of things.  They usually prefer to leave the electronics design and hardware production to someone else anyhow, so it is a mutual arrangement.

I love to design and build projects involving vintage Altera CPLDs and FPGAs such as the Altera MAX7000 and MAX9000 series of Altera components. Over the years, I have a managed to collect a large arsenal of vintage Altera programming hardware from the late ’80s and early ’90s.  Mainly for the Altera master programming unit (MPU) released by Altera in the early ’90s. I have been building up an arsenal of the programming adapters for this system. Certain models are very hard to find. Due to the rarity of this Altera programming system, I am currently working on designing my own custom adapter interface that will essentially allow me to connect any compatible Altera component to the system… without the need of the unique adapter. A custom made adapter essentially.  Not too complicated at all really, it’s just a lot of fun to build and then have the glory of trying out other components.

I love to design, build, and program FPGA projects using the VHDL hardware description language and also interface to external memory and sensors. I have a devoted website and YouTube channel where I post various hardware repair videos or instructional videos for many of my electronics projects. Each project has a devoted webpage where I post the instructional videos along with written procedures and other information relating to the project. Videos from “Robotic Arm Repair” to a “DIY SEGA Game Gear Flash Cartridge” project. I even have VHDL software tutorials.

The last project I shared on my website was a project to help students dive into a VHDL based VGA Pong game using the Altera DE1 development board.
