First GD32 tests

Wednesday, November 9th, 2016

Sjaak has published a new build, the STM32/GD32F103 QFN32 breakout board: Uptill now I used 0603 sized resistors and capacitors but for this project I switched to 0402 to save a few mm on the board. I have soldered many challenging chip packages so I felt confident. The technique is...

UCload: revisited

Monday, April 4th, 2016

Sjaak has posted an update on his uC controlled dummy load project we covered previously: I finally found some time to check out the UCload project. A couple of weeks ago I quickly soldered the PCB and wrote a quick’n’dirty firmware for it. The basic functionality was working, but it...

Over the top UCload

Wednesday, December 30th, 2015

Sjaak has published a new build, uC controlled dummy load: I'm mostly a digital guy, but I'm wanting to design my own power supply. If I'm wanting to test that i need a dummy load. I got inspired by the re:load (www.arachnidlabs.com/reload ). I added a microcontroller, rotary switch, external...

Basic Experimenter Board for rapid prototyping of electronic circuits

Wednesday, January 28th, 2015

Raj of Embedded Lab has published new project the Basic Experimenter Board for easy prototyping of electronics circuits: Most electronics projects require some common stuff like regulated power supply, input tact switches, and output LEDs during prototyping and testing phase. Wiring these things on a breadboard for every new project...

Makeblock – Mechanical prototyping platform

Monday, December 17th, 2012

[embed]http://www.youtube.com/watch?v=sFOSBuL03vc[/embed] We met the Makerblock team during our Shenzhen Maker Faire visit earlier this year. They let us know that their system is close to being finalized. It's a mechanical prototyping platform designed to make it easy to assemble robots, linear actuators, and other mechanical devices. Now, we improved a...

DIY breadboard modules for rapid prototyping

Monday, November 21st, 2011

Raj made a few breadboard modules to speed up prototyping. We think it's a great idea to have a power supply, few switches, LEDs, etc, broken out into modules. It will save you a ton of time, and space on your breadboard. Breadboards are a great tool for prototyping and...

Designing PCBs for automotive applications

Sunday, April 17th, 2011

This application note gives PCB design tips for reducing EMI in automotive environments. A lot of the advise can be applied to any PCB layout. Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) testing is an important part of design verification for serializer/deserializer (SerDes) devices in automotive applications. EMI and EMC...

Updated Fritzing release

Wednesday, March 2nd, 2011

We previously highlighted Fritzing, an open source GUI based program that allows users to document their prototypes, share them with others, show them in a presentation, and create a pcb layout for professional manufacturing. The developers have released an updated version, which contains a number of improvements including a completely...

Teflon insulated wire trivia

Tuesday, February 1st, 2011

AkosL writes in with a prototyping tip: Try teflon insulated wires. (Or other heat/wear resistant insulation materials).  Why? The insulation is very resistant compared to "common" insulator materials. Both mechanically, and heat resistant (the one right in front of me is rated to temperatures between -60°C to +200°C). You could...

USB POV Toy: Soldered prototype

Tuesday, November 2nd, 2010

Here's the soldered prototype of the USB POV Toy.  The first power up exploded a backwards tantalum capacitor with an impressive spark, but after that was sorted everything seems to be ok. The tiny MMA7455L accelerometer took a few tries to solder, but now we can access it with the...
