Hi, I want to introduce a new cap rail enlosure set for NodeMCU V2 Amica modules (ESP8266-E12). The heart is an additional pcb with integrated voltage regulator and breadboard. It fits together with the NodeMCU in a 3 module DIN rail enclosure:&...
IntroductionI’d been curious to experiment with E-paper displays for a long time, and recently I finally got around to some basic experimentation. This short blog post documents some work with a compact 2.9 inch display, building it into a simple clo...
2017 was a busy year, I had a lot of personal stuff to do, but there was lots of engineering related stuff going on too, and I enjoyed seeing what everyone was working on. This blog post lists the activities I worked on. Project/ActivityD...
Note: The project is experimental. The project is low power and low voltage, and requires a low voltage source which can be derived from a mains transformer.However there are significant risks with building mains powered projects. For that reason, it...
IntroductionMany integrated circuits nowadays have a pad on the underside that needs to be soldered down. It can (for instance) serve as a ground connection or it might be needed to be soldered for better heat dissipation. Since the pad is not expose...
IntroductionThe Digital Multiplex (DMX) protocol (not the rapper : ), also known as DMX512 or DMX512-A, is an industry-standard method of achieving lighting control, both manually (using a control panel) and for lighting automation (using a PC). It f...
Hi, I want to introduce a new project of me. A friend asked me for help with his Lincoln stretch limousine car. The car has originally an interior control via capacitive sensor keys based on a Atmel controller. This solution have som...
IntroductionSometimes it gets tiresome remembering keyboard combinations for software applications on the PC. Examples include CAD software which are very feature-rich. One could place labels/stickers onto the keyboard but maybe the keyboard isn’t su...
I thought it would be good to have a discussion about peoples experiences with fake and recycled components, and share photos so that others can be aware. As an introduction, it should be clear to most that if it a component deal seems too good ...
IntroductionThe LimeSDR board is a CrowdSupply project that I was curious to try out. It was priced extremely well for a very high bandwidth (60MHz) software defined radio board with a usable frequency range from around 30MHz (or lower with some mods...
IntroductionI recently had a PCB made overseas, just for a one-off prototype. I spent a few hours examining the boards so I thought I’d share my findings. This is not a review, I do not intend to name the manufacturer, because this is a one-off ...
In 2016 I got to explore a few things, here is a quick summary. Project/ActivityDescription Building and Testing Audio CablesThe year was kicked off with an investigation into audio cables and jack plug connectors and how to solder them and how ...
IntroductionFor years I’ve used a normal pair of tweezers to pick up small parts. It works fine but in the quest for further improvements I looked to buy a vacuum pick-up (also known as vacuum tweezer) tool to assist in this process but I didn’t see ...
IntroductionHYDRA, named after the multi-headed monster, is a miniaturized general purpose electronic engineering tool with several bits of functionality. For instance an audio amplifier and an LED can allow for some quite extensive debugging fo...
IBM made history this month for being the first company to deliver quantum computing to the Cloud. The tech company encourages researchers and science enthusiasts alike to test out its platform and provide feedback that could bring useful quantum pro...

The Zephyr Project is an initiative to bring a real-time operating system to low-power IoT-connected devices and technologies. The platform is open-source and might be the buffer needed to address IoT security concerns. (images via Zephyr) The I...
IntroductionIt looks like the FTDI USB-Serial saga continues. A USB-Serial (also known as USB-to-UART) interface is used to connect up PCs to hardware devices using the USB port. FTDI was traditionally a manufacturer of the interface chips for this p...
The mysterious BeagleBone Blue promo image (via BeagleBone)BeagleBoard.org just released a page on their site dedicated to something called the BeagleBone Blue (BBB). On the page is a picture of a PCB with the words “robotics cape” riding atop a Beag...
A project born around the LinkIt ONE board is an experiment of a full open hardware and open software untile to reach a product. HugoA dog-wearable device for dogs, that remain more than one day in standby mode. This IoT device is based on the O...
(Some over used stock art. Seemed to fit the theme.)Although as a society, we’ve long asked for the day technology can overtake everyday, mundane tasks. That reality is closer to fruition than ever before, and now is the time we should take a step ba...
In 2015 I tried to find some time to explore some things – here is a photo summary. I got to meet some friends, try out some things, and do some research from time to time. The items here can be found in the various blog posts over the past year...
