Smart Stick Using Arduino Uno: Aiding The Visually Impaired

Obstacle detection is one of the major concerns for a fully or a partially blind person (e.g. person suffering from night-blindness, cataracts, glaucoma, albinism or injury). Presented here is a smart...
Active AC analog probe

Low Cost Dual Channel Active AC Analog Probe

Introduction When we are experimenting with AM receivers for LW, MW and SW we are in need of high impedance analog probe with low input capacitance, e.g. well below 20pF. The required input...

Micro-Solder Pot

To make a great solder joint, component preparation is a must. This sounds unimportant, but it is very important to clean the component leads, wires and contact surfaces prior to soldering...
Bipolar power supply
