🎯 Features It all started with a tiny board called Digispark, powered by something called ATtiny85. This little board has a cool trick up its sleeve – it can act like a keyboard or mouse when programmed right. I've seen similar...
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...
WCH has introduced a line of small RISC-V MCUs with USB and BLE. The 3 major branches of the family are the CH573, CH582 and CH592. They mostly only differ in the level of BLE - from 5.2 to 5.4. Looking for an inexpensive way to check...
Manufacturing of Large Dye Sensitized Solar Cell at home from Shih Wei Chieh on Vimeo. Introduction Dye-sensitized solar cells (DSSCs) represent an easily manufacturable and cost-effective photovoltaic device and can be done at DIY level. However, its...
Keyboard The keyboard is a PocketType miniature ortholinear 40% keyboard kit available from Mechboards - https://mechboards.co.uk with numbers and symbols accessed by layer keys. It is microswitch based and OK for thumb based typing...
This is a project for a small benchtop galvanostat - a device that can be used for direct current or pulsed current galvanic deposition of metals on small conductive objects. Essentially, it is a voltage-controlled current source (based on Howland current...
Overview My personal goal has been to use this project as a learning platform for myself. So far, I’ve been able to explore all sorts of software and hardware that I hadn’t worked with previously. I’ve been kid-in-a-candy-store, getting to...
A seismometer, is an instrument used to detect and record ground motion caused by seismic waves, such as those generated by earthquakes, volcanic eruptions, or other sources of ground vibration. Basically, the seismometer consists of two parts,...
The initial board The initial circuit was published bye "Mdog" and did exist into two versions "solo" and "4axis". Both of these boards rely on the Ti LMD1845 H bridge circuit. The LMD18245 is a full-bridge power amplifier with 2• DMOS Power Stage...
I picked up a vintage HP 1600A/1607A logic analyzer set over the weekend which was state of the art back in 1975. I thought I would see if I could at least get them running and functional and then maybe develop some interesting stunt! I was surprised...
CONTEXT After creating v1.0 of the Companion Light (check it out: https://hackaday.io/project/194589-the-companion-light-v10), it seemed that I was able to reach a wider audience for the project. Successful indeed! Now, with the upgrades planned and...
Several years ago, I had to learn how to use National Instruments Circuit Design Suite (Multisim and Ultiboard) to create a circuit schematic and PCB layout for a new job. This was so that I could better understand the software, and help students with...
Leakage control is very important in this vehicle, which operates with a nominal 48V BLDC motor. The insulation control on this electronic card is provided by coding it with the STM32F103C8T6 microprocessor. This card, which works with the logic of...
I love using Attiny microcontrollers for my little creations.With this simple opensource project, I wanted to create a small and compact programmer (without cables) for the 8 and 14 pin Attiny microcontrollers.The Arduino sketch to upload to Wemos mini...
