USB Power supply Active Load Tester or short PAL Tester is unit designed for testing the quality of the power supplies. Idea was to create low-cost, precise device for simultaneous measurement of Voltage and Current drawn from the device under test. This is one of my weekend projects that I have decided to release to […]

Another DIY project designed with Solo-Lab.com’s SoloPCB Designer tool is ready to be shared with Electro-Labs community. This is an USB stick which measures the supply voltage of the USB port and current drawn by the device connected to the port over the stick. Then it calculates the power consumption of the device and displays the

Li-ion cells become more and more popular due to their capacity and reasonable prices. In this entry I will show how to build a simple li-ion battery charger based on MCP73831 chip. It’s a quite useful device for DYI projects, in addition its cost is only around 1,5 euro. The device uses USB port as

This page is dedicated to everybody needs to program a PIC (Microchip) device via USB port. Looking on the web for ready-to-use projects, I found a good one called Open Programmer, coming with several schematics, PCBs and Open Source code. The original link is http://openprog.altervista.org/OP_ita.html What concerned me was the need to mount, on the

The CANable is a hardware clone of Eric Evenchick’s CANtact project, an open-hardware USB to CAN adapter compatible with socketcan. I took his design and reworked the hardware to be a bit more suitable for my personal needs, with a screw terminal instead of a DB9 connector and a much smaller PCB. The design is

The adjustable power supply is an absolutely vital piece of equipment for any electronics engineer or hobbyist. However in the vast majority of cases the needs presented towards a lab power supply are quite relaxed and usually within the low voltage range. With the modern component base the current consumption is usually also very low,

USB data-acquisition modules offer good value and ease of use, which makes them an attractive choice for manufacturing test. But before you use the modules in a manufacturing test system, you need to take steps to protect them. During manufacturing test of circuit boards or subassemblies, a defect in an assembly may result in a
