In Part 1 of this series, we have reviewed solar cell performance, how to select and size the supercapacitor, requirements of supercapacitor charging circuits and charging IC characteristics. We will now use two case studies to illustrate these properties in detail. Case Study 1: Using a small solar cell indoors at low light, 100 lux, […]
You’d be hard pressed to find a carpenter who didn’t own a hammer, or a painter that didn’t have a couple of brushes kicking around. Some tools are simply so fundamental to their respective craft that their ownership is essentially a given. The same could be said of the breadboard: if you’re working with electronics

This is the first post of a 3-part series about reading out an SMA solar inverter over Bluetooth and displaying some readings every few seconds. Long-time readers may remember the Solar at last weblog post from several years ago and the SMA Relay, based on a JeeNode v6. The Bluetooth readout code was derived from Stuart Pittaway’s Nanode SMA
Castellated Edges Castellations are small plated edges, typically used for making circuit boards into small pcb modules. These are often seen on wireless modules, such as the ESP8266-12E. While we don’t offer full support for castellations, they can be fabricated if you don’t mind a few minutes of rework and verification of the PCBs. Design

If you’ve recently found yourself spending too much time looking at memes on your phone, or you’ve noticed you are becoming unnervingly familiar with Netflix’s back catalogue of obscure conspiracy theory documentaries, it might be time to find a new hobby. Preferably one that’s not going to rot your brain. And if you happen to have an
There are plenty of techniques and components that we use in our everyday hardware work, for which their connection and coding is almost a done deal. We are familiar with them and have used them before, so we drop them in without a second thought. But what about the first time we used them, we

Description I started this project two years ago but lost interest last year after being stuck with the custom board. I since got it working, and will share my findings. The idea is to control an old broken kindle 3 eink display with a FPGA. I started looking at http://essentialscrap.com/eink/waveforms.html and http://spritesmods.com/?art=einkdisplay since eink constructor
Everyone playing with electronics these days knows about LED strips made of dozens or hundreds of individually addressable RGB LEDs. I love them and make great use of them in the nootropic design Lumazoid music visualizer. But what about incandescent lamps? Old-school light bulbs with a filament have a soft warm glow that you just

3D Printing became an important process in prototyping, and sometimes in manufacturing. But till now, the filament types available in the market are limiting printing colors. Although there are many multi color printers, printing a design in full color is still a dream. XYZprinting has announced its da Vinci Color printer, the world’s first full color
