References for Universal Glucometer
Log from Universal Glucometer
This is a partial list of references I have used so far in researching the design and operation of glucometers, glucose measurement techniques, strip design, etc. (I continue to find and read new resources). I've included links to articles or abstracts...

Reverse engineering
Log from LCD light box conversion
Powering it up again, I used a multimeter to measure the pins on the backlight connector. I didn't know which pin was ground, so I started by using the metal frame, and found a small voltage on 3 of the lines, and 34V on the last. Trying to measure the...

Reverse Engineering Continued
Log from Shower Metronome
The mystery part was identified as a transformer.When it was removed from the original PCB one of the enamel wires came loose from the case pin. This resulted in an intermittent/partial connection and a lot of frustration during testing. This was fixed...

Progress Reverse Engineering
Log from Custom Display for Elliptical Trainer
When adjusting the resistance of the exercise machine, one single digit of the large time dispaly (the 10's digit) is shown on the screen. This is perfect for reverse engineering the protocol because there is very little data change from sample to sample...

PCB reverse engineering done
Log from It's evolving: Aiphone video intercom
I certainly took my time but after long hours of tracing PCB tracks in Paint.net, identifying components and putting everything together in Kicad I finally ended reverse engineering the 2 PCBs there is in this video intercom.To help me achieve my others...

Reverse engineering the RainCloud
Log from RainCloud de-cloudifier
The RainCloud product has two parts1) An irrigation switch that runs on 4 AA battery with 4 output. This irrigation switch has 4 hex character id. 2) An RF transmitter connected to internet through an Ethernet cable. This transmitter sends command...

Reverse Engineering the Protocol
Log from Custom Display for Elliptical Trainer
I'm beginning to reverse engineer the protocol used by the LCD controller. I think this is simply prefaced by a memory address and then the binary values for which segments of the LCD should be turned on. If I'm right, the memory address will always...

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....
