Welcome to TekMaker

TekMaker is a channel designed to help people of all ages and abilities to learn about and build projects for Computers, Electronics and now Amateur Radio too. Having witnessed many poor quality and badly informed channels I decided I could do better. I previously worked in Electronics for 25+ years including design work and been involved in computer servicing, networking and programming for over 20 years. I hope to produce projects and videos and instructions that are simple enough for any age or ability. That said some projects are main voltage powered and should be built with extreme caution and supervision. You do this at your own risk! Rather than just making projects to use once and then put on the shelf I will endeavour to make projects that will connect or work together and for useful things if you want to set up an electronics or single board computer lab at home.

RGB Photoflood - An Arduino Project

RGB LED Photoflood Links to code and video at the bottom of this article So, I was looking at the price of photo floods for photography and video production and baulking at the prices. I had previously used a battery powered one with 160 LEDs that cost around 20 GBP which was ok for basic photography lighting fill-in, that is to supplement room lighting. But for video you really need something more powerful. So my criteria was  Must be mains powered Must be RGB programmable for effects Optional - can display scrolling messages Must stand prolonged usage Cheap enough to make several to provide multiple light sources, possible with differing tints. Easy to construct and copy. Common sense and available components said it should be Arduino based because I have a drawer full (or did) There are many variants as cheap as 3 GBP + postage and packing in multiple pack purchase They are easy to program and have simple power needs, i.e. 5 volts the same as WS2812 LEDs I have seen WS2812 256 LED p
