Pogo pin test board for ADB-USB Wombat

A pogo pin tester for the ADB-USB Wombat board from Big Mess o’ Wires: Here’s a test rig for the ADB-USB Wombat board: my first-ever project whose sole purpose is to facilitate testing of another project. It uses spring-loaded pogo pins to create a bed of nails that fit into test points on the Wombat board. […]

Simple crystal tester

Dilshan Jayakody writes: This is simple Colpitts oscillator to test commonly available passive crystals which range between 2MHz to 27MHz. This unit must connect to an oscilloscope and/or frequency counter to get the frequency of the crystal. This circuit is design to work around 9V to 12V DC power source. Both 2SC930 transistors can replace […]

USB power supply active load tester

Sasa Karanovic has designed and built a DIY USB power Supply active load tester, that is available at GitHub: 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 […]

Inductor saturation tester

In relation to the previously posted Power inductor checker,  Lindsay refers us to Alan Yates’ article on inductor saturation tester: As a result of recent work on switchmode power converters I needed the ability to measure the saturation properties of inductors. This simple instrument was built to allow visualisation of the current ramp as an inductor charges from […]

USB current and voltage tester designed on the DP5031 standard PCB

Here is TitanMKD’s USB current, and voltage tester designed on the DP5031 standard PCB. The board features 4 standard USB connectors, while voltage and current can be measured via 4mm banana terminals For those interested in a cheap funny board to test USB current consumption/voltage or even check USB D+/D- and ID signal The goal […]

Prototype: Flash_Destroyer

The most recent documentation is now on the wiki EEPROMs, such as flash memory, store data in electronic devices like cell phones, smart cards, SD cards, and solid-state drives. This type of memory can only endure a limited number of writes, it will eventually wear out and it won’t store new data. The Flash Destroyer […]
