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 matrix keypad form.…... [Continue...]

Homebrew Multimode Digital Voice Modem (MMDVM) adapter

Florian Wolters made his own version of MMDVM adapter: During experiments with digital voice mode in hamradio I discovered a nice project describing an adapter for D-Star, DMR and other digital modes based on an Arduino Due and a little PCB to be put on top. This unit is called…... [Continue...]

The Onion Omega2: The Latest Router Dev Board

A few years ago, the best way to put a device or project online was by hacking a router. With an inconspicuous Linksys WRT54G held onto a project with baling wire, anything can connect to the Internet. A lot has changed in a few years, and now those routers are development…... [Continue...]

MicroPython on the ESP8266: Kicking the Tires

Scripting languages are for large computers, right? “Real” embedded device work is a hellish, never-ending cycle of code, compile, and re-flash. Well, I used to think so too, but with the proliferation of scripting and other interactive languages to microcontrollers over the last few years, the hurdle to interactive development…...
