TV Tuner IR remote with a PIC16F684
Tahmid built a TV tuner IR remote with a PIC16F684: I then proceeded to write an IR transmitter using the PIC16F684 (using the MPLAB X IDE and XC8 compiler), following the timing information from the extended NEC protocol. In order to connect all the keys, I connected them in...

by Clemens Valens @ elektormagazine.com: The new PIC32MM family, currently Microchip’s lowest power 32-bit PIC32 family, features sleep modes down to as little as 500 nA. Filling the gap between the PIC24F XLP and PIC32MX families, the new family also offers so-called core...

Pete show us how to upgrade your ESP8266 with 32Mbit memory chip. Some time ago I passed comment in here about converting an ESP-01 to 32Mb (or 4MB). And here it is in the flesh – a 32Mb ESP-01 – and also – at last – Sonoff Upgrades. Now, why would you want to do all...

Johan Kanflo’s Esprog pogo pin connector: The FTDI connector can be found on just about any ESP8266 design. If you are building a gadget to be deployed somewhere and not a full blown development board, the FTDI connector is somewhat overkill. And it is quite large. A few pins...
