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...
I was looking for a solution to open and close the window when king Cat or queen Cat decided to go outside without me having to get up and open the window by myself. I first thought to motorize the window with something like a linear actuator or some...
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...
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...
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...
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. ...
A programmer is a device used to program a microcontroller. Usually, it is just another microcontroller with a special program to communicate with a host (PC) and download a program to a device (MCU). However, most the time, programming a MCU requires...
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...
TFT screen is 160x128 pixels, 1.8 inch with ST7735 driver.The MCP2515 module drives the CAN BUS. The circuit supply is from the car 12V , 5V regulator generates the 5V for the TFT and MCP2515. Setting up filters in the MCP2515 is for allowing only 7DF...
