    In retrospect, it would have been much less fiddly to write this in C/C++

Reverse Engineering the D-Link BSDD16+ Display

Electrical

This router, like a bunch that I've taken apart, has a status display driven by a series of registers. There are six 8bit registers here, and they're Fairchild 74VHC164s. The datasheet for them can be found here.

After minor poking, here's the pinout to the display PCB:

#Feel free to extend/modify to meet your needs.
#Maya on Ubuntu v.1
#This is the base installer... I’ll add more features in later versions.
#if you have any issues, feel free email me at heiths@gmail.com (or Edwin at EdwinGuy@Gmail.com)

#### Lets run a few checks to make sure things work as expected.

The plan this time around is to take a one-button remote control car and make it autonomous so it can wonder the house on its own. One day maybe I'll have it map things using a Raspberry Pi Zero, but for now it will be Arduino controlled and use an ultra-sonic sensor to 'see'.

The toy car itself is pretty simple, and seems to be designed to be modular with the control chip being on a daughter board. All of the control for lights, motor and sound run to that board-to-board connector making it easy to hack! For those looking for their own, it seems to run under the name "My First RC Car" and it's manufactured by a company called Parent's which is out of China. It has three following delightful traits:

1. Six transistor-controlled LEDs (no idea amperage ability, 3 channels with two LEDs each)
2. A speaker with amplifier (for vroom-vroom noises)
3. A single momentary switch just for beep-beep noises
4. A one-way single button radio
5. A zainy drive system that can go forward or steer to the left (no reversing p

Reverse Engineering the Epson M-31a Printer Module

Electrical

Well, this guy seems pretty common to different printing calculators. I managed to find two different makes with the same module while shopping around at Value Village. The rule is to buy two (one to break to pieces, one to hack) but I broke my own rule along with the calculator and I now have to hunt down a third.

The pinout for the module from left to right is this:

The first 4MB of the file is a mystery, but the UBIFS seems to be stored uncompressed in the file and the UBIFS system is also uncompressed. You can find config files and others in the dump

UBIFS header starts with hex 31 18 10 06. I found this at offset 0x6593A, but I'm having trouble because the chip doesn't come with the nandsim kernel module.

I'm trying to follow these tutorials to mount and extract the root file system:

• https://bootlin.com/blog/creating-flashing-ubi-ubifs-images/

The partitions for UBIFS on the CHIP are the following:
