maxtc - Breakout board for Maxim SPI thermocouple sensors

Submitted by GG on Thu, 03/15/2012 - 10:15

maxtc bare pcb The Maxim MAX6675 and the newer MAX31855 thermocouple to SPI interface chips are very popular with electronics enthusiasts because of their extreme ease of use combined with good accuracy.
Both devices however are only available in SMD package making breadboard prototyping very difficult without using a suitable breakout PCB. Standard thermocouple connectors are also not breadboard friendly further aggravating the issue.

microjs - Freescale S08JS microUSB minimal system

Submitted by GG on Thu, 09/15/2011 - 19:42

microjs on a breadboard The freescale S08JS series is one of the lowest cost microcontrollers with a hardware USB implementation. The availability of free C development tools (SDCC and Codewarrior) make the S08JS a great candidate to develop all sorts of inexpensive USB gadgets. microJS is a fully functional S08JS minimal system on a PCB less than a square inch. The board headers can be plugged into a breadboard for prototyping or soldered to another PCB for a permanent placement.

PCSX movie quality fix

Submitted by GG on Fri, 02/12/2010 - 19:39

Improved MDEC Code This patch resolves a video quality bug in PCSX (and derivatives) and since it is a complete rewrite of the mdec.c file it also allow PCSX to be completely licensed under the GPL.

The rewrite is based on an implementation of the AAN (Y. Arai, T. Agui, and M. Nakajima) IDCT algorithm plus some optimizations based on extra information on the coefficient matrices provided by the RLE decoder.

Matrox Millennium II Xv extension

Submitted by GG on Fri, 04/07/2006 - 13:56

DVD video on P3 This patch will enhance the X.org 7.1 Matrox Millennium II driver to support the X video (Xv) extension (extremely useful for playing DVDs and other video formats). The extension is implemented as a CPU to Frame Buffer YUV scaling ILOAD. A true overlay was not used because of a Millennium II hardware limitation that would reduce the maximum usable frame buffer to only 4Mb.
