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....
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...

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...
The first step for this project was to figure out just what exactly the two remote control codes involved are. To do this, I built an ugly version of the "silver bullet". With this new weapon at hand, I pointed a remote control at it and pressed...
In honor of DEFCON, this week we’re looking at some cryptography and reverse engineering projects over at Hackaday.io Every hacker loves a hardware puzzle, and [Tom] has created a tool to make those puzzles. His Hardware Reverse Engineering Learning...
The next step in this project is attempting to interface a special sunlight-readable "transflective" LCD panel, out of an old Portege R500 laptop. I couldn't find a datasheet at first, so I embarked on a huge task to reverse engineer the pinout by probing...
A few months ago, I started to reverse engineering the main PCB. Having only my Galaxy S10 as a photography device, as usual I took the best photo I could with it, imported it in Paint.net and worked on tracing back the PCB pattern. However,...
I have a HDMI switch with a PIP feature that would be very interesting for my project. Unfortunately it seems a bit more complicated to get it working with a single button. I could use an IR blaster to control the switch (it will probably end this way),...
I'm going through and following the encoder pins for Channel 1. So far I've found that the encoder channels go into a basic transistor switch circuit:Then it goes into the 74 series logic. This is taking a long time to trace, but here's my progress so...
Okey, here is where this project gets slightly out of hand.I was not expecting to build the entire remote but what seemed impossible yesterday became inevitable. In order to do this, I first needed to identify the correct pins and then hook up my BusPirate...
Since my dog ate the remote, I figured it would be cool to design a new housing for it. The new housing will be 3d printed and can include any custom features I want. The first step, however, is to just recreate the original remote enclosure as accurately...
As you can see airodump-ng picked up the WiFi of the drone and also that it is running on channel 2. Next I recorded some packages. sudo airodump-ng -w JJRC_out -c 2 -bssid 10:A4:BE:2E:77:B5 wlan0mon While recording I simply used all the functions the...
OK, “reverse engineering” is a bit of an exaggeration here, but that was essentially the vibe when I first hooked up my mystery LCD component to an Arduino Nano. I’m not big on either Fritzing or Eagle, so I made a sketch of the wiring...
Prostar 16x16 Panel Reverse Engineering Basics I started by looking up the data sheets on the two chips found on the board - the ST2226A and the 74HC245.The 74HC245 is a standard high speed bidirectional 8 bit buffer. Datasheet is here: http://pdf1.alldatasheet.com/datasheet-pdf/view/351465/ONSEMI/74HC245.html...
