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:
| #!/bin/sh | |
| set +e | |
| if [ "" = "$1" ]; then | |
| echo "You need to specify a host dummy" | |
| exit | |
| fi | |
| cat ~/.ssh/id_rsa.pub | ssh $1 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys" |
| #!/usr/bin/env python3 | |
| import serial | |
| import binascii | |
| #open serial | |
| ser = serial.Serial( | |
| port='/dev/tty.usbserial-A6005kdh', | |
| baudrate=115200, | |
| timeout=0.005 |
| #!/bin/sh | |
| sudo apt-get install -y libgl1-mesa-dev libglu1-mesa-dev libsm6 libxrandr2 libxcursor libxcursor1 libxft2 libxi6 libxinerama1 |
| #!/usr/bin/env python | |
| import errno | |
| from sys import stdout | |
| from time import sleep | |
| from select import poll, POLLIN | |
| from inspect import getmembers | |
| import xwiimote | |
| def get_device(entry): |
| #!/bin/bash | |
| # usage: <drive path> <folder name> | |
| # | |
| # ex: copy.sh /dev/floppy0 "Where in the World is Carmen Sandeigo" | |
| let a=0 | |
| echo "Creating directory for '$2'" | |
| mkdir -p "$2" |
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:
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:
| #!/usr/bin/env python | |
| ''' | |
| Tool to read game media type header information from the original | |
| XBOX's xbe executables. | |
| In retrospect, it would have been much less fiddly to write this in C/C++ | |
