This is one way to combine your ATX Breakout Board with a ATX PSU. Simply drill 4 small holes into the PSU, and attach your board onto it. We recommend using standoffs and the top acrylic sheet from our ATX Breakout Board acrylic case to enclose this design. Get the ATX Breakout Board from Seeed […]
Global Geek Tour Bangalore day two. Assembly at NSK electronics. Follow the pics live with our twitter feed, or wait for them to pop up on the blog. More pics below the fold.
Giving a talk on open source hardware to a really generous audience at the Center for Internet and Society in Bangalore. Watch for live updates of our Global Geek Tour of India on twitter. If you hate the social media craze wait for it to pop on the blog.
Hardware hacking is more fun with open source, DIY tools. That’s why Arhi designed a completely open soldering station controller motherboard. And we designed a through hole version that is now available as a PCB only at Seeed for $7 The completed PCB is the heart of a soldering station, able to control several types […]
Microchip sent two tubes of mislabeled 23lc1024 SRAM chips to play with. First project is Logic Shrimp v2.
Filming geek tour went well on day 1. We will be eating one of these on the food crawl tomorrow!
After days of soldering off and on, 14 nixie thing modules are good to go.
Completed Nixie module. The wiring was a huge pain. Only 14 more to go.
5 more new prototypes on the bench. First the big chips then the little stuff.
This little VFD cutie comes from our trip to akihabara in Tokyo last year. A block of 6 of these will go on the Nixie vfd thing.
All six tiny VFD tubes we got in akihibara last year will probably fit in one Nixie block on this Nixie thing.
The driver module for the nixi pile is working great. Counting 0 to 9 using a Arrrrduino to clock out bits to a 74hct595. The 8 outputs of the 595 drive two k1551-whatever Russian Nixie driver chips. The Arrrrduino will be replaced with a higher speed chip so a string of modules is easy to […]
Nixie tube supply is working great at 180 volts and 12k anode resistor.
Didn’t design our own. Used great open source SMPS from desmith.net. 180v from 12 volts out of the atx break board in handsome new case. Design uses max1771 from maxim. Sorry – posted from WordPress Android app. Fixed the picture.
More deliveries. Solder is slinging. Workshop video in a few.
Putting the final touches on the video from Sjaak’s workshop. Don’t miss the part where he sets a diode on fire.
Look great. Socket hole is a little too short and needs to be filed down. Not bad though.
