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...
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...
A geophone is a device used in geophysics to detect ground movement. It is specifically designed to measure seismic waves, which are produced by various sources, including earthquakes, and explosions. Typically consist of a mass suspended on a...
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...
I did this project because I was annoyed with having to use my phone while driving to open the gate, which is GSM controlled by calling its number, and takes a while to open, so you really want to call in advance. This way I can just push two buttons.It...
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...
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...
Overall Details. Normally you have an off-grid system that can, if necessary, be powered by a battery charger from the power grid. If there is less sun in the winter transition periods, the battery voltage drops due to discharging during the shade periods. ...
1. Design The golden traces correspond to those of the T-800 brain chip (bottom view). 2. Schematic (old school) The brain chip is a TLC555, which is responsible for the Terminator's eyes blinking in a fading manner. 3. PCB
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...
