Working on adding Audio-Out circuit
Log from RETRO 1 - Home Computer Console
The MMBASIC interpreter on the PicoMiteVGA supports a couple of audio output methods as standard.I am currently breadboarding the various options to try and get a nice version for this project.The VGA-to-HDMI converter that we have used in this project...

Ultra low cost microcontrollers
Log from 1 dollar TinyML
If the complete BOM for sensor is to be under 1 USD, the microcontroller needs to be way below this. Preferably below 25% in order to leave budget for sensors, power and communication. Thankfully, there have been a lot of improvements in this area over...

Initial Testing
Log from Delta Printer - Capacitive Nozzle Probe
An Arduino ESP32 was setup using touchRead() in the main loop to toggle the onboard led and stream the read value out over Serial. A single 15mm x 15mm x 1mm pad was tested with dial indicator to get a feel for the trigger range. The led...

Iterations
Log from Delta Printer - Capacitive Nozzle Probe
Went through several iterations of testing the accuracy with minor tweaks to the Arduino ESP32 code. Activation by ISR, different types and levels of filtering, and changes to the touchRead() default configuration. The default (0x1000) measurement...

Project journal
Log from STEbus Z180 slave board (SP180)
2024-01-20 I've just found and bought this board from eBay. Made by DSP Design Ltd. It uses the 7-thou pitch DIL packaged device (ugh!) which can only access half the memory of the PLCC68 version. I don't expect this to come with a manual or circuit...

Fixing the Real-time Clock
Log from Portable Pi
Out of the box, a Raspberry Pi 4 does not have a real-time clock. When it is booted up, it initially displays the time it was shutdown at - then when it connects to the network, it updates the time via Network Time Protocol (NTP). I fitted a DS3231 real-time...

Design phase
Log from Lunar PICO rover
Currently finishing out the design phase of the robot, along with acquiring/building all of the parts. Done-Tested PICO board controlling a motor and a servo Printed main chassis and it failed Redesigned main chassisAdded LoRa COM module...

USB Serial Adaptor
Log from Un-Inhibiting my Microcoin QL
Bottom Line Up Front Was it a $5 part? I don’t recall. It’s just a USB serial adaptor. Look mom, there’s a Tx and Rx pin. What more is there to say? Next. TL;DR My point: We should not take our systems, devices, and components for granted. It’s...

Dumping the TMS1100
Log from Exploring the Science Fair Microcomputer Trainer
This post details the approach that Sean Riddle and I took when dumping the code contained in the Science Fair Microcomputer Trainer (SFMT) back in 2015. This built on previous work by Kevin Horton (aka Kevtris). Although I'm writing this...

DHT22 Wireing
Log from GreenGuard: The Smart Plant Environment Monitor
DHT22 Sensor: The ESP8266 in the diagram is mounted on a breadboard for easy connection and may be programmed to send the data it gathers from the DHT22 to the Raspberry Pi or directly to the cloud for monitoring.It is powered through a micro USB connection,...

Hardware and libs
Log from TinyML meets dog training
For my first trials I decided to use the TinyML kit: which contains Arduino Nano 33 BLE Sense and the OV7675 camera (kit). I use the following libraries on arduino IDE:Arduino Mbed OS Nano Boards v3.0.1Arduino_OV767X v0.0.2Arduino_TensorFlowLite (from...
