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...
On starting up, the display value flashed continuously. I guessed that it does that to indicate 'overload' on the resistance range, and this is indeed the case. It showed steady and accurate readings when measuring a resistor. Voltage measurements agree...
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...
Introduction The project involves designing a PCB based on the ESP-12S module to create a WiFi repeater capable of extending the range of WiFi signals. This repeater will amplify and rebroadcast existing WiFi signals, effectively extending the coverage...
The body is made of two stainless steel hemispheres. One is plain and the other has holes for screws/screen. The hole for the screen was cut on a lathe. Surprisingly tricky to fixture - having the chuck point spread out instead of clamping down worked...
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...
Phase 1: My goal is to design five PCBs that include resistors, capacitors, active devices and various input and output components. These will mount on a laser cut wood base similar to the original design, but smaller. One of the issues...
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. ...
