This Instructable describes the construction of an electronic archery arrow spine tester. An arrow spine tester measures the stiffness of arrows. This helps an archer to construct arrows of uniform specifications which will shoot consistently. Traditional arrow spine testers measure arrow stiffness, or spine, by hanging weights on the arrows and measuring the resultant sag […]

The GLC-9000 Leakage Current Tester provides comprehensive testing for general purpose electric equipment. Saelig Company, Inc. has introduced the GWInstek GLC-9000 Leakage Current Tester performs leakage current (also called touch current) tests on general purpose electric (IEC 60990) equipment. This tester uses nine measurement device networks to simulate the human body interacting with equipment under test. Leakage current testing is needed to

Intro What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power supply, as most of the designs out there are using slow components. However, I

This is something I’ve already worked on but was never really happy with the result, mainly because the potentiometre that I used was of poor quality and hence non linear and “jumpy”… The problem is simple: I need to have a reliable and easy to use servo tester, that I can use to test/play with a

When I’m building Solar Shrubs and other solar-powered creations, I often scavenge cells from various off-the-shelf devices such as solar garden or security lights. But these cells are rarely labeled as to their voltage, current, and power output. So it’s off to my bread-boarding station. First, I put each cell under a lamp and connect it to my multimeter to get

A month ago I knew nothing about Arduino and now…..my first project! Looking back, this project combines allmost all of the tutorials that I have read in this short period: blinking LED, push button, piezo and LCD display. A useful project for every beginner! I have made this device for some of my friends who
