Retrocomputer Resurrection

This chimera is a microcontroller emulation of a UK101, an 8-bit microcomputer from the early 1980s. Needless to say I had one; it is a shocking thirty-three years since, as a spotty teenager, I soldered one together over the course of a few days. I recall the kit cost the equally shocking sum of £99.95 (a lot of pocket-money), and had to be smuggled through Irish customs in my parents' car because the Sing ...

Use ESP8266 module as a wireless switcher

After we managed to connect the ESP8266 WiFI module to Raspberry Pi, we can now try to change the module firmware to a custom one. The firmware we will install on it is a simple webserver, that will handle HTTP requests. It will allow us to access a web interface for ESP8266. The interface will allow us to search for available WiFi networks, choose one and login. We will also have a page that will control t ...

Friwo LED drivers will light up your LEDs as much as you just want

Power supplies for LED lighting (so called drivers) are available from many producers, in a various qualitative level. Why to decide just for the LT series from German company Friwo? Here are few reasons: • precise design, safe operation and a long lifetime • voltage and current regulation in one device • high efficiency and a possibility of dimming in a range of 0-100% directly via a CTRL pin • modules are ...

Quick-Turn PCB shop review project: Elecrow

After my initial PCB success with Maker Studio, I uploaded the design files to three more board houses. I had planned to try four or five more, but I started to get the impression that many of the China-based sources used the same fab house, so I stopped at three. Elecrow's basic board fab service supplies 5 or 10 PCBs for $11.90, with a basic international shipping cost of around $7 for 5 boards. Although ...

LiFePO4 Charger

since I really like using LiFePO4 AA and AAA batteries in some of my projects [1][2][3], I finally gave in and built a dedicated charger for them. Previously I used a lab power supply to mimic the constant current/constant voltage charging curve, which worked also fine. But after seeing Patrick Van Oosterwijck nifty LiFePO4wered/USB™ [4], I thought it would be a bit more convenient to charge these batteries ...

Liquid Cooling Moves onto the Chip for Denser Electronics

Using microfluidic passages cut directly into the backsides of production field-programmable gate array (FPGA) devices, Georgia Institute of Technology researchers are putting liquid cooling right where it’s needed the most – a few hundred microns away from where the transistors are operating. Combined with connection technology that operates through structures in the cooling passages, the new technologies ...
