Single chip AVR BASIC computer

Friday, July 11th, 2014

Dan over at HackAday documented his single chip computer project with the PCBs from DirtyPCBs: A single AVR microcontroller (the ATmega 1284P) has been used to create a standalone computer system which runs the BASIC programming language. The 1284P runs TinyBASIC Plus, generates RCA video signals (using TVout) and reads PS/2...

NEW PROJECT: BGA Reballing Practice Kit, removal, reballing, soldering exercise

Thursday, May 1st, 2014

At Hacker Camp Shenzhen we learned to reball BGA chips at a mobile phone repair school. This technique was developed to repair cell phones with little to no equipment. That means no expensive reballing rigs, no collection of tiny replacement BGA balls. Just simple hand tools. We thought it was...

Troubleshooting damaged chips

Tuesday, April 1st, 2014

Steve at Big Mess o’ Wires writes: The most common failure I’ve seen is something I call “burnout”, and has affected about 4% of the units. After anywhere from one minute to a few hours of working normally, the Floppy Emu stops functioning, and both the 3.3V regulator and the...

Drag soldering for surface mount chips

Wednesday, February 5th, 2014

[embed]http://www.youtube.com/watch?v=9Sfggumc-Tc[/embed] This video by Steve of Big Mess o’ Wires demonstrates how to solder a 44-pin chip in a typical TQFP package using the drag soldering technique: The process begins by applying a liberal amount of flux to the pads, then positioning the chip on top. I use a pencil eraser to hold the...

555 as a push-pull level shifter

Monday, December 16th, 2013

psmay writes: Wanting to prototype something with an oddball push-pull 3.3V-to-13V switch led me to concoct an experiment using only stuff available at a reasonably well-stocked Radio Shack[3], with particular attention to ICs that provide push-pull outputs. So far I’ve tried configurations based on the original 555 timer[4] and the...
