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...

Single chip provides 3D images inside the heart and blood vessels

Friday, February 21st, 2014

Researchers at the Georgia Institute of Technology have developed a new medical imaging technology that provides 3D imaging from inside the heart and blood vessels: The device integrates ultrasound transducers with processing electronics on a single 1.4 millimeter silicon chip. On-chip processing of signals allows data from more than a hundred elements...

Microchip PIC chips could have been the Power Behind Arduino

Tuesday, February 11th, 2014

Gerry Sweeney writes: As I understand it Microchip are in the silicon chip business selling micro-controllers – actually Microchip make some really awesome parts and I am guessing here but I suspect they probably want to sell lots and lots of those awesome parts right? So why do they suppress...

Drag soldering for surface mount chips

Wednesday, February 5th, 2014

[embed][/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...

rompar: a tool to analyze masked ROMs

Thursday, July 18th, 2013

You may have seen those highly magnified photos of decapped chips displaying the hardware architecture and wondered what information is represented by the solder-like designs. Adam "Major Malfunction" Laurie of Aperature Labs has developed a software tool to assist in deciphering the bits represented in these highly magnified chip photos....

AD75019 crosspoint analog switch

Tuesday, May 28th, 2013

Paul over at Dorkbotpdx has written an article about his AD75019 crosspoint analog switch: The chip is controlled by a big 256 bit shift register.  I just chained the 3 chips in tandem, so the shift register is 768 bits. In the regression tester, I used 3 of these chips...

Macroblock MBI5030 starter board

Thursday, February 21st, 2013

Macroblock MBI5030, is a 16 channel constant current LED driver with PWM output, and a SPI-like interface, it requires external grayscale clock though. The problem: you need the chip to figure out if your code actually works. And you also need the LEDs to see what’s going on – if...
