Reverse engineering my new LCD
Log from LCD Solar Creatures
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
Log from Daktronics 16 x 16 RGB Panel Reverse Engineer
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...

Prostar 16x16 Panel Reverse Engineering - Data IN
Log from Daktronics 16 x 16 RGB Panel Reverse Engineer
Prostar 16x16 Panel Reverse Engineering - Data IN The DataIN or DIN signal is the pathway that gets the data that needs to be displayed into the panel's driver chips and thus to the LEDs. It is a serial input signal and each driver chip in the design...

Jasmine Brackett3:00 PMHello Everyone! I'm @jasmine, and I'm your Hackchat host for today. Murilo Polese3:00 PMheyo! :) Jasmine Brackett3:01 PMFor those who don't know me (as I don't hackchat too often), I run Tindie.com but used to be the community...

[E1][R] Q8100-60002 reverse engineering
Log from SecSavr Suspense [gd0105]
[19 Feb 2023, 12:00] I've spent the past 70 minutes finding continuity between the cable holder and the test pads, as well as any

Reverse-engineering vintage quartz resonators
Log from Clockwork germanium
The seller provided the following picture but even after receiving the crystals in tubes, many questions remain.First, is it series or parallel resonance ?Then what type of cut is it ? https://en.wikipedia.org/wiki/Crystal_oscillator#Crystal_cuts has...

Reverse Engineering the BASIC Program
Log from Optronic Laboratories 740A/D Spectrometer
I uploaded a copy of the BASIC program that ran the system. The important part was this, which I annotated what it did. With this Information and finding the interface to the spectrometer is a 48 line DIO board I was able to figure out what lines did...

Reverse Engineering the LCD controller
Log from New PCB For Calculator Watch
Disclaimer: I have never before done anything with LCDs directly There are three things that I've learned, that are essential to drive an LCD segment. For easier understanding just think of one segment with 2 pads or legs that you have access to. There's...

Reverse Engineering the Keyboard, Part II
Log from Psioπ
So I got another package in the mail today, and this little guy was inside!This was a purchase from the local eBay branch Tradera, and as you can see it suffers from a damaged display connection. Other than that, it seems to boot just fine. -'But RasmusB,...

Reverse engineering the keyboard, part I
Log from Psioπ
The first part I'm attacking is the keyboard. The keyboard is the reason I want to build a "modernized" Psion, I really like this form factor! The plan is to convert it to a USB keyboard since that will work with any modern computer, but before I can...

Reverse engineering the U-boot binary
Log from Manhattan SX - Hacking a low cost DVB-S2 receiver
Since the application boot sequence is hardcoded (not defined using bootcmd) we need to dive deeper into how this works. Using Ghidra I have decompiled the U-boot MIPS assembly code to understand more. I simply loaded the DRAM dump performed earlier...

Reverse engineering automotive backup sensors
Log from Hoverbot
Aftermarket automotive backup sensors are cheap and ubiquitous. They use transducers to produce an inaudible ping and receive the reflected response - the time it takes for the ping to return indicates how far away any potential obstacles...

Prostar 16x16 Panel Reverse Engineering - The input and output connectors
Log from Daktronics 16 x 16 RGB Panel Reverse Engineer
This section is under construction:Now we have enough information to map out the important parts of the Input connector. We will also look at the output connector.First the input. The pinout of the input connector looks like this:InputPinout.jpg (Under...

Reverse Engineering Motor Signal Board Day 9 - Done!
Log from Reviving and Reverse Engineering an Old Robot Arm
Or as done as I'll ever be. I've got all the traces finished and the layout complete. Some things still don't make too much sense, but I won't be able to figure them out until I finish the main processor board and figure out what those connections...

Reverse Engineering Motor Signal Board Day 5 - Restart, ugh
Log from Reviving and Reverse Engineering an Old Robot Arm
So I realized something - the entire board is laid out on a 0.100" grid. Every single pin of every part (besides two connectors that have a 0.085" pitch) is on that grid. And it lines up. Knowing this, I went back to photoshop and used this to make sure...
