Getting Ready for Reverse Engineering
Log from eeColor Color3
(Also published here.)Today was all about getting set up for reverse engineering the board connections. The SDRAM, LEDs, buttons, and FTDI chip connections have already been figured out in the past, but the Silicon Image (SI) chips have not. And those...

Reverse-Engineering the Collar Protocol
Log from Automatic Dog Door Smart Home Interface
The collar uses a 40 kHz ultrasonic transmitter. I attempted placing a transmitter emitting a 40 kHz pure sine wave tone near the door, but that just resulted in an LED blinking to indicate interference. It turns out that the system has some protection...

Fan Control Signal Reverse Engineering
Log from AutoDuct smart motorized air duct shutter
To be able to open and close the shutter when the fan is active or not, the signal of the stock ventilation control bus (pluggit IconVent 160) needs to be analyzed. Using an oscilloscope reveals a pulse width modulated (PWM) signal with a 5V amplitude...

Reverse Engineering of several polygon mirrors
Log from OpenExposer
In November last year, i reverse engineered several polygon mirror units of some laser printers i've got from friends. I also ordered some further units from ebay. Now a attiny2313 regulates the mirror motor speed. The attiny2313 should be a part...

Reverse-Engineering Diagrams
Log from Soviet Drum Machine Repair & Reverse Engineering
First, it was tracing the connections between chips on the control board, resulting in the Diagram of Discombobulation:...and then, recombobulating the aforementioned diagram into something easier to understand and trace.The system is built around a...

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 LCD Controller
Log from The ZStation: an 8 bit game console
A game console is nothing without some form of output, and LCD displays are expensive for the size I want. Lucky for me, a friend of mine gave me an old printer to tear apart, and now I have an LCD that very conveniently has an LCD controller board already...

Reverse engineering cont
Log from LCD light box conversion
This does call into question what the three lines to the backlight are. Perhaps they are not RGB, but instead are just different segments of the backlight. My first thought was to quick pull off one of those resistors and see how it changed, but remembering...

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...

Protocol Reverse Engineering
Log from Outback MATE Reverse Engineering
The next part is to figure out how the protocol works, and the format of the data.I started with taking some live captures in a running system (A MATE connected to an MX charge controller), and looking at what kind of packets were being exchanged. The...

Reverse Engineering Motor Signal Board Day 4 - Full Board
Log from Reviving and Reverse Engineering an Old Robot Arm
I decided to just reverse the entire board. Less error prone that way. I've got all the IC footprints on the board, most of the resistors and capacitors, and most of the filled zones. This is testing my patience.
