CC269: Break Through Designer’s Block
A heatsink epoxied atop the linear regulator on this Arduino MEGA board helped reduce the operating temperature to a comfortable level. This is certainly not recommended engineering practice, but it’s an acceptable hack. (Source: E. Nisley, CC269)

Are you experiencing designer’s block? Having a hard time starting a new project? You aren’t alone. After more than 11 months of designing and programming (which invariably involved numerous successes and failures), many engineers are simply spent. But don’t worry. … Continue reading

CC267: Continuity of Embedded Tech Content
A fan under the black CPU heatsink keeps it near ambient temperature, so that the Peltier module under the aluminum block can control the MOSFET temperature. The gray epoxy block holds a linearized thermistor circuit connected to the Arduino microcontroller under the PCB. (Source: E. Nisley)

The October issue features articles on topics ranging from FAT cache to IIR digital filters to a quadcopter that uses a mechanical gyro. Let’s review. On page 16, Stuart Oliver details how to use math routines that include the dsPIC … Continue reading

CC266: Microcontroller-Based Data Management
This is the complete portable accelerometer design.  with the serial download adapter. The adapter is installed only when downloading data to a PC and mates with an eight pin connector on the PCB. The rear of the unit features three powerful
rare-earth magnets that enable it to be attached to a vehicle.

Regardless of your area of embedded design or programming expertise, you have one thing in common with every electronics designer, programmer, and engineering student across the globe: almost everything you do relates to data. Each workday, you busy yourself with … Continue reading

A Dutch Designer’s “Comfort Zone”
workspace Stegeman

Check out this amusing workspace submission from Henk Stegeman who lives and works in The Netherlands (which is widely referred to as the land of Elektor). We especially like his Dutch-orange power strips, which stand out in relation to the … Continue reading
