This project is currently shelved while I complete a couple iterations of the "1978 Heathkit Digital D&D Dice Tower" I wish I had as a kid playing AD&D. But, don't fear it will get resurrected in a number of future projects including the Digital D&D...
At that moment in time, the "Hobby" computer was cut of the edge technology:- compatible with both of the major Z80 operating systems of the time: CP/M and ZX Spectrum- single (256 x 192) and double (512 x 192) screen resolution- hardware switchable...
The power supply is comprised of four stages:AC Mains to 390V DC converterCurrent limited 390V DC to 1950V DC converterHV Multiplier DriverHV MultiplierThe HV multiplier and it's driver are the core of the project. Together they convert the 1950V DC...
Current spec list: 1-2* voltage sources (-5V - 5V, sourced from 12bit 1MSPS DAC) 1 current source (+/- 15mA) 2 voltage measurements (12bit resolution @ 1MSPS, variable gain, AC or DC coupling, 100kHz bandwidth)**2 current measurements (80kHz bandwidth)Fixed...
(Update - recently designed and ordered a PCB using EasyEDA for this project - see picture in gallery) When the ESP is reset it comes up in mode where it is monitoring each of the battery's cell voltages. Every one second, voltage measurements are taken;...
This is the first Passive house / Port Alberni in the Heart of Vancouver Island, British Columbia A 1080 sq ft Rancher wheel chair accessible. built to the Passive codeFoundation are 3ft 915mm by 8in 203mm with 30in 762mm by 8in 203mm walls, insulation...
EDIT: I am correcting the details of the project indeed since the beginning in 08/22 the project has evolved a lot. Will we run out of water? There is water almost everywhere on earth but when we talk about fresh water, there is only 2.5% on our planet....
Onboard Programmers are great On microcontroller development boards (such as ST Nucleo Boards) it's very handy to have an integrated JTAG programmer/debugger. If you would like to build your own board with an embedded programmer, things get a bit tricky.In...
Using Inkscape set the document to a defined size, lets say 500px Now we make a 250px rectangle. Then export it as PNG, but be aware to use the same size (500px) of the whole document. Now we can export it as PNG, but we need BMP. I use the...
The extremely small form factor in PowerBlade is made possible through two insights. First, other plug load power meters make contact with the AC through prongs, and provide another socket for the device (TV, fridge, etc) to plug into the meter. This...
One Bit CPUs There are a couple of one bit CPUs on the Internet. I have start with the MC14500B chip. This chip was used many years ago for PLCs but the documentation is still available: http://tinymicros.com/mediawiki/images/e/ec/MC14500B_Handbook.pdf...
In this project I will take a conventional toaster oven (any kind of toaster oven can be used) and design a precision controller to turn it into a reflow soldering oven. I know there are already plenty of controller kits available out there, but I hope...
This project aims to help me understand RC frequency filters and the basics of op-amps (and their derivative, LM386 amplifiers). The circuitry forms two main "stages" in which the audio is processed to make a Christmas light display.Though this is a...
ESP_8_BIT is designed to run on the ESP32 within the Arduino IDE framework. Schematic is pretty simple: ----------- | | | 25 |------------------> video out | | | 18 |---/\/\/\/----|---> audio out | | 1k | | | --- | ESP32 | --- 10nf | | | | | v gnd |...
SolidCore CoreXY CAD Design In Fusion 360 All Metal Parts Our long term goal is to is to build a modular platform, not just a printer. Think of it as an ecosystem of parts that can be arranged in different configurations and adapted for unique applications....
