Firmware hacking
Log from Model S BMS hacking
Here is a rough schematic of the isolated bus circuitry. It looks like there is some shared "open collector" style bus on CH4 of the isolator, with D8 and (I assume) a pullup on the BMS controller board. But so far I've only ever measured this line being...

The Story So Far-- Explodophone 1.0 Part 2
Log from The Explodophone
Now for the other half. For maximum starting flexibility without taking the cost too high, I opted to go two octaves, using notes found on the white piano keys only, i.e., notes with only letter designations and no sharp or flat symbols. This means I...

First video out
Log from Gigatron TTL microcomputer
It seems I have reached the base camp. The el-cheapo 7-inch LCD monitor on the right is connected to the output port of my breadboard TTL computer. The computer is now running at 6.3MHz and runs a software loop that generates a VGA test signal. The colors...

Directory Stuff
Log from OSI SD Card Operating System (OSISDOS)
I put a bunch of files on the SD card so the directory spans across multiple blocks. It might be fun to have a directory listing. The front of the first directory block has: 000 42 20 00 49 00 6E 00 66 00 6F 00 0F 00 72 72 00 B .I.n.f.o...rr. 010 6D...

B1+B2 completed. Also, facing my first real problems.
Log from 74HCT6526
Finally, B1 and B2 are completed and they.... kinda work... Although I'm going to have to check quite a few things.Remember how B0 performed flawlessly, both when connected via the expansion port, and when replacing CIA#2? Well, that's no longer true....

EC or not EC: that is the question
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
For some reason, EC probes are relatively expensive. In most cases they are more expensive than pH probes, which to me seem a lot harder to make. So, I decided to make my own EC probe, as you can see below:The contacts are gold plated Studex ear piercing...

Topology (1)
Log from Programmable Precision Resistor
In this post I want to share how I selected a suitable topology for the resistor network that will be the core of the programmable decade resistor. Although I did some online “research”, the following criteria determined my choices: Switch...

rf24boot: A huge update
Log from rf24boot: The NRF24L01 bootloader
There hasn't been much going with rf24boot for a while, till I was playing with esp8266 and accidentally writing frankenstein firmware for it. Despite being cool and cheap, esp8266 still consumes way more than nrf24l01, so I'm back to rf24boot. This...

Solder the LiPo battery
Instructions from Detective Boys walkie talkie pin badge
You will need a Lipo battery with 100mAh capacity, you can get a higher capacity one but take into account that more capacity means a bigger battery so it won't fit into the board, the battery must have a protection circuit included. The battery must...

A lot of googling to start.
Log from LPC Serial Port
The first thing I did was try and find a device that could do what I wanted. I found this https://www.digikey.com/product-detail/en/maxlinear-inc/XR28V382IL32-0A-EB/1016-1974-ND/4515332 which should be exactly what I need. Its too much of a device for...
