Sound
Log from Dodo: 6502 Game System
All along I knew I wanted to figure out sound for Dodo because a game system just wouldn't be right without it. I have been going back and forth with lots of different approaches in my mind. Dedicated sound generation chips that mixed both digital and...

New Beginnings
Log from Z80 Computer
Well, I did it. I ordered my first custom circuit boards. I laid out a prototyping board with an ISA bus card edge, sent it to dirtypcbs, and after a month of impatiently checking the mailbox, they arrived. I ended up with eleven boards. After I've built...

Log from EasyIoT Cloud
We added ESP8266 WiFi PIR motion sensor.

Demodulating and parsing AcuRite temperature data
Log from re-purposing acurite temperature sensors
Contents: one Arduino Pro Mini 5v; one RFM12B, slightly modified; one compiled program; two AcuRite temperature sensors.A first draft of the code is published:https://github.com/JorjBauer/acurite_decoderwhich happily spits garbage like this out the serial...

Log from Cosmic Array
At the Sydney 2018 linux.conf.au, Paul Schulz will be giving a presentation about the Cosmic Array and software development. Paul, has been a key person in development of the sound and wireless networking aspect of the Cosmic Array....

The Keyboard
Log from Anatomy of a Philips VideoWRITER
Before I start this log on the keyboard I should mention that I'm in the process of putting all of my writings and software on the Video Writer on a small website. The following is an almost direct copy of what will be the article about the keyboard......

Next attempt with new library
Log from My own "a million times clock-clock"
So, after the last attempt (without acceleration) worked, I realized that the accelerations are hard to compute for two handles in parallel for an ATMEGA328 with the accelstepper library. The square root calculation takes a lot of time. So I have two...

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...

Thermals
Log from Cortex Guitar Board
I recently borrowed a thermal camera to figure out how hot the board gets, especially when powered from the higher end of the expected supply voltage range. This is an image of the board taken with a thermal imaging camera. The shot was taken after feeding...

Some pictures
Log from Big Daddy 68k
Assuming everything has gone to plan, and you've wired up the circuit as described, you're left with something looking like this!Along the top row: three 74-series logic gates performing the address decoding, the static RAM and then the Arduino.Along...

20230212d -- LCD Display
Log from ROM Disassembly - AlphaSmart Pro
The LCD is a 40x4 character display. Judging by my friend [Eric]'s@EricHertz photos, this is not the common HD44780 device, but instead a Mitusbish M50530 I did find a datasheet for this device. If it's not code compatible with the '44780,...

Registers A & B
Log from Homebrew Machine 2
Last night I built and tested registers A & B. This is an easy place to start as these registers are only two chips each.One of my goals for this project is to avoid using Ben Eater's schematics. When I built my first computer, I followed his...

Dummy's questions regarding CPLD
Log from Very simple CPLD trainer
CPLD is a programmable logic and NOT analogue component but when I think about logic component in 74 series, they are working for some exceptional operation. Here I confirmed two "exceptional" cases. These fact should be well known by experts but please...

RPM CAN Address found!
Log from CAN BUS Gaming Simulator
I finally got the address for the RPM needle! Baudrate: 500kbpsIt's 0x280!So how do you control it?unsigned char stmp[] = {1,0,0,rpm_int}; CAN.sendMsgBuf(0x280, 0, 8, stmp); The first line creates a new array with 4 spaces. (The last one "rpm_int" is...
