Details from GPXR General Purpose ( VR / AR / MR ) XR
In the Maker community there are projects to make Virtual Reality headsets to use with the PC, but these are for wired use, so there is room for a wireless solution that does not involve using a cell phone. Currently the best: https://hackaday.io/project/187343-easy-pancake-lensesAnd...

First simple proof of concept - October 2016
Log from Cosmic Array
Here is the first simple proof of concept idea using Geiger–Müller Tubes (GMT) and coincidence detection using logic gates which worked first time.Simulation of how I imagined this circuit might work.Actual first strip board prototypeFirst live...

Machine cycle level debugging
Log from Custom circuit testing using Intel HEX files
With the memory and I/O map looking good (see test approach in previous log), I decided to complete both MiniMax85 single board computers, expecting they would work. Well, they didn't :-( After exhausting all the usual simple debugging steps (voltages...

Log from Novasaur CP/M TTL Retrocomputer
The testing phase has been using NOR flash memory. The fastest version is rated at 70ns, and although much better performance was observed, it will not support a dot clock above 25MHz. The final design will use the 55ns rated Atmel AT27C020. A similar...

Tweaking BASIC on SmartResponse-XE
Details from Tweaking BASIC on SmartResponse-XE
The work by others to port Arduino BASIC to the Smart Response-XE device was of interest, but I wanted a few enhancements to extend battery life (auto shutdown) and I wanted an easier way to do math on the console rather than typing "PRINT" everytime...

Systems Overview
Log from Neucuff: A soft orthotic exoskeleton
The basic concept behind actuating the Neucuff is that you can detect intentionality of arm movement in a person with Cerebral Palsy by performing signal processing on their bicep's motor neuron activity. There is some research out there in the medical...

1st Prototype PCB Testing
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/DYE So what do the polyphonic waveforms actually look like when playing four different notes? Pretty...

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...

Section #1
Log from Apollo Saturn V and LUT
Lights: There are almost 250 lights on LUT, not including the swing arms. To get the correct scale look, the proper number of lights, fairly dim will be the best. For this I had a bag of 3mm white LEDs from a previous project. I ordered another 200,...
