Resistor Kit - 1/4W (500 total)
Resistors are a good thing, in fact, they’re actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you’re gonna have the resistor you need when you need it is to stock up, and keep them organized. We have just the thing! Our new branded resistor kit comes with 25 each of 20 different resistor values (including 0? links!). All of these resistors are stapled into a tri-fold pack and clearly labeled. The back of the resistor kit even has a resistor color code look-up chart and a table of color codes for th..

Infrared Remote Control
Have you ever needed a cheap way to activate something from across the room? Infrared remotes are still the cheapest way to wirelessly control a device. We have designed the remote to be small, very simple, and low-cost. For the majority of the projects we build, we don’t need 34 buttons, we need one or two. It makes more sense to provide you with a cheap and easy to use remote. Our infrared remote control offers buttons for four directions, power, select, and three optional use buttons (labled “A,” “B,” and “C”). Unfortunately we can’t guarantee that it will work with your Stuart Hughes' Pr..
