🎯 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...
In South Africa, our electricity supply is somewhat erratic, due to around 2 decades of under-investment, and incredible levels of corruption. As a result, many residents have resorted to installing solar power, with battery backup to ride out the 2-4...
Code Details: After provisioning the EP10, configure this code for the plug name and the hours to charge before turning off. In this example a 4-hour charge time worked fine. Upon code startup if the plug is not detected (typically the EP10 is unpowered)...
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...
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,...
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...
I am fortunate enough to have Home Assistant Yellow running in my home. I am also fortunate enough to have a favorite human that is brilliant at creating micro-controller gadgets. He created his own temperature and humidity sensors that connect to MQTT...
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...
Especifications Power supply redundancy. Critical functions can run even during multi-days power outagesAll devices (RPi, Critical Nodes, Modem, DVR) can be powered on/off remotely. Current and Voltage are measured and logued. 4G backup internet...
Overview of RVECC: RVECC encoder has a 32-bit data input (din) and generates a 7-bit output syndrome (ecc_out). The 7-bit output syndrome is prepended to the data and sent through the channel. The output of the channel is sent to the RVECC Decoder. The...
