GLINK-LT - User Port RS232 for Commodore 8-bit Computers

glink232GLINK-LT is a modern clone of the Commodore VIC-1011A RS232 User Port adapter for Commodore 8-bit computers. The adapter is fully supported by the standard Commodore BASIC at up to 2400 baud. Jumpers allow the card to be configured as a UP9600 for 9600 baud operation in Novaterm and Striketerm. A reset button is also provided for added convenience.

GLINK232 - UART cartridge for Commodore 64/128

glink232Both the commodore 64 and the 128 have a software UART implementation that limits the useful speed to 2400 bauds. To work around this limitation Dr. Evil Labs and later CMD produced the SwiftLink232 and Turbo232 cartridges based on the 6551 ACIA chip. Both of these have been out of production for a very long time.

GS2HD - Apple IIgs RGB to HDTV Component Adapter

GS2HD D00The apple IIgs, like many computers from the 80's and early 90's, has a analog RGB output at a 15KHz horizontal frequency (same as NTSC/PAL). The majority of modern monitors and TVs will not sync to anything below 31.5KHz on their VGA input. If you have a TV with a SCART connector it is possible to wire the RGB directly to the TV. Most TVs in USA, however, use the YPbPr component instead of SCART making a direct connection not possible.

Kicad Debian Packages from GGLABS

Kicad LogoKicad is the EDA software we use for all our projects. All the computers in our lab use GNU/Linux (either debian or Mint LMDE). The kicad version in the debian repository is from the stable kicad branch so it is quite old (Nov 2014) and missing many useful features. After manually compiling kicad for several months we decided to write a script to automatically generate a proper debian package and make the packages available to the public.

6-10W boost LED driver

ssr01 pth versionHigh power LEDs require a constant current power supply for optimal operation. GLED1 is designed to drive 10W white LEDs (9 diodes in series) from a 12V or 24V supply. The board can be used down to 3V but the maximum output power will be reduced in this case. The design supports discrete level dimming using a two or three way switch or continuous control using a PWM signal. The design is based on the ON Semiconductor NCP3065/3066.

FLIRC and GGLABS at the East Bay Mini Maker Faire

EBMMF LogooGGLABS and our good friends at FLIRC will be sharing a booth at the East Bay Mini Maker Faire on October 19th. If you plan to attend the faire stop by our booth to check out the features and ease of use of FLIRC and other miscellaneous GGLABS projects. We will be also showing some projects still in development stage that have not been published yet.
