WiFi LED Light (ESP8266 + WS2812B + Lua)

Markus Gritsch shared his WiFi LED light project in the forum: I built a prototype for a WiFi controllable LED light, using the popular ESP8266 module running the NodeMCU firmware [1]. To allow controlling the WS2812B LEDs from Lua, I extended the firmware with a bit of C code Check out the video after the break.

Diolan plus2 – Diolan bootloader with standard instruction set

nyholku writes: To support my EazyCNC Project I I’ve create a version of the original Diolan bootloader that I call ‘diolan-plus2’ and which does not use extended instruction set making it compatible with C-compilers and still retains all the features of the original diolan bootloader and fits in the 2kB bootblock. Diolan-plus2 published on GitHub. […]

Matt Coates of Sky Labs Electronics writes: So here it is! Courtesy of Dangerous Prototypes Dirty PCB service, I have been able to put together and complete the testing of the first prototype of my very own location based development board. So lets talk about what you’re looking at. The board is a 4 layer PCB of dimensions […]

Nixie Tube Thing – Dirty PCB to the rescue!

Crawford writes: I have been lusting over the Nixie Tube Driver that Ian brought to the 2012 World Maker Faire. When I met him there I asked about board production, but he explained it was a one-time thing. Fair enough. Well it’s 2014 now and DirtyPCB exists. I grabbed the design off the forum, and […]

OV7670 image sensor data capture with Atxmega32E5 without using external FIFO

Kehribar has interfaced a OV7670 camera module with Xmegae5 microcontroller without external FIFO: With current configuration, this system sends 20FPS 80×60 grayscale image data over 3Mbaud serial stream. There is 3 byte preamble {0xAA,0x55,0xAA} to indicate the start of a new image frame. Computer software / other MCU can use those bytes to sync with […]
