Hardware Design
Log from 65c02 Homebrew Computer on breadboard
In terms of hardware design, I realised that there are not really that many parameters one can play with when using off the shelf components. The point is that things like the 6502, 6526, 6522, 9918 etc. are by design expecting certain inputs and outputs,...

[E1][R][X] AirBerries: Learning a custom keyboard layout
Log from Tetent [gd0090]
So I've recently got a fully electrically and mechanically complete CAD model of Tetrinsic and was, once again, doing some research for Tetent, mainly because I don't like how this featureless flat face looks: It turns out that the eteeController...

We're crowdfunding!
Log from uECG - small open source wireless ECG sensor
Finally we got to post on Hackaday! We're back from Makerfaire - it's been a very busy time. Lots of people (20+) tested our device in the field, so to say, and ironically, it could be considered a stress testing for our device, though we couldn't measure...

Capacitive Touch PCB Experimentation
Log from Polyphonic Touch PCB Piano
To start off, thanks to JLCPCB for sponsoring this project and providing the pcbs I designed. JLCPCB Prototype for $2 (Any Color): https://jlcpcb.com/DYEFirst step in this project was to read up on some literature (links below and in video description)...

Translating a neural network to a discrete component memristor
Log from Discrete component object recognition
The goal of this task is to describe the steps needed to translate a neural network onto a discrete component implementation Sample neural network As a starting point we'll use a simple neural network with two inputs or signals and two outputs or classes....

Battery Sizing
Log from DIY Solar Bottle Lamp
Earlier I used a 0.5W straw hat LED, but it is not so efficient and the lumens/watt is around 70-80. So I am planning to replace the LED with a 0.5 Watt cool white SMD LED ( 2835 package). As per the SMD LED datasheet,...

[E3][T] Ball chains?
Log from Tetrinsic [gd0041]
[23 Dec, 10:00] Whilst I haven't been able to find any human-computer interface (Charachorder, TapXR, ...) or unique and repurposable musical instrument that has as much of a solution coverage as #Tetent TestCut (or #Tetent Timespy [gd0136] if...

Further tests
Log from Controlling a JJRC H37 Elfie quad from a PC
Today I captured a bit more traffic from the application to the quadcopter and played with the on-screen controllers to see how that would affect the messages. Here's what I got. By moving the controllers, some of the bytes in the message change (these...

improved encoder reading
Log from Whiteboard Drawbot
The software I'm modifying does an encoder read as follows: int rot = ((digitalRead(BTN_EN1) == LOW) << BLEN_A) | ((digitalRead(BTN_EN2) == LOW) << BLEN_B); // potentiometer uses grey code. Pattern is 0 3 switch (rot) { /** logic to interpret the value...

Built in audio output
Log from Teensy LC chord strummer
This was not a thing on top of my list, but I got curious of the Karplus-Strong implementation in the Teensy Audio Library, and took 30 minutes of my lunch break to put it in my strummer. The Teensy Audio Library requires at least a Teensy 3.2 to work,...

Exploring the Instruction Set - Architecture
Log from Suite-16
Suite-16 The inspiration for this project was to design a 16-bit TTL computer loosely based on Steve Wozniak's 16-bit virtual cpu "Sweet-16". It written in 6502 assembly language to augment the Apple II when performing 16-bit operations. Sweet-16...

Low-Voltage ECL : part 1
Log from Germanium ECL
My logs about speeding up the 2N2369A have brought a lot more of insight or CDC's RTL logic, as well as confidence in my methods, and the results are very good. So the next step it to explore the following technology node : ECL. One defining angle of...

Simulation with falstad
Log from Precision current generator
Jim made a simulation on the online interactive simulator falstad, available there : http://tinyurl.com/ycj63egd I've tweaked it a little (I display more values) : $ 1 0.000005 7.619785657297057 65 5 50 t 224 240 176 240 0 -1 0.6771607865907852 -0.5873050244463638...

ROP2 with Falstad
Log from YGREC8
Note: this log is obsoleted by BitsliceAfter the last log Adder with Falstad, I also converted the ROP2 bitslice to the interactive simulator : There is still the challenge to disable the output of the CLA so it can be combined by ORs with the rest...

On I/O
Log from KZ80
The biggest challenge right now is I/O into the system. I'd eventually like to support KeyboardLCDSerial / UART for attaching modems and other such thingsCompact flash driveA Counter/Timer Circuit (CTC) Last night, I realised I could use a handful of...
