Reverse engineering the EPROM
Log from Twitter feed on an old LED marquee
My initial plan was to desolder the microcontroller (a Winbond W78C32C-40 MCU, with an 8051 core) plus a few other logic chips in the board, then add some wires to control the LED circuitry. But desoldering was tougher than I thought, and while in the...

Reverse Engineering - Schematic
Log from 127 TowerPro Servos, one I2C interface.
Sat down last night, with a pencil and paper, broke open a servo to work out what was inside.We've got some metal gears, ball bearings, a brushed motor, a potentiometer and the interesting bit -- a circuit board.The servos are labeled as "DIGI", which...

Reverse engineering the keypad
Log from BluEtoothOcom 600
I had my time completely occupied by lectures and exam, but today i finally found some time to continue from where I left off: understanding how the keypad works. Smelting the problems away Due to the age of the device, I wasn't able to get any output...

Reverse engineering - first steps
Log from Late 90s GPS time unit repair & 1024-week bug fix
At this point it was late November. The obvious thing to do, given the device was working, and just displaying (and outputting on the serial port) the incorrect time, was look at using it as an accurate 1-PPS source and connecting it to a Raspberry...

Controller and reverse engineering
Log from Unity Candle
I need a controller which can implement the required sequencing, implement the positive manual enable, and a lock system to prevent unauthorized use. A convenient way to do testing while adjusting parameters would also be helpful.Digging in my parts...

JM20330 Reverse Engineering
Log from M.2 SATA to 44P IDE Adapter
The central component of this project is a PATA to SATA bridge IC. Unfortunately, there doesn't appear to be any suitable chip with (officially) publicly available documentation, so figuring out how to use them can be tricky. The most common IC for this...

X-40 laser tape reverse engineered
Log from Cheap laser tape measure reverse engineering
I have bought cheap Chinese "X-40" laser tape. I disassembled it and found that it is really contains laser module that I reverse engineered earlier: But the module version is "701A", it's not like "512A" that I bought earlier: It can been...

Reverse Engineering the Screen
Log from Bistable LCD e-Paper eReader
Origin I first saw this screen on the ZBD EPOP 900 electronic shelf label (ESL). Thought it is going to be fun just reverse engineer them, so I bought a few of them: PCB After I got them, the first thing I tried was powering them up. And... I got nothing....

Reverse engineering mechanical parts
Log from Psioπ
I have been able to spend a few hours on the project, and I thought I could share some of the progress so far.I was going crazy trying to figure out a solution to the screen and processor dilemma. I still haven't figured out a perfect solution, but I...

Turboscreen Platform reverse-engineering notes
Log from Telstra T-Hub rooting/repurposing
These are just general notes from my reverse engineering efforts. No effort has been made to present them in a tidy manner, expect a write-up later.The display is connected to DI0 *NOT* DI1 as I had previously assumed.Backlight is wired into PWM unit...
