Hello, in this project I want to show you how to build a multi functional Police Light with a Attiny25/45/85 . It will have serval animations , which can be changed with a button on the circuit board, it has 2 channels, which can be controlled with PWM. That allows us to add serval animations

Introduction Having to use a Raspberry Pi and other USB Devices in an electronics production environment where 5V isn’t standard, I have noticed a lack of power supplies capable of fitting in. A unit had to be designed to fit into systems where 12V & 24V are the norm or where batteries / solar panels

An Arduino, some addressable LED’s, a bluetooth module, code and a 3D printer come together to make blueShift – An OpenXC LED Tachometer. blueShift is so named for the Bluetooth protocol used for data communication, and the use of a tachometer to indicate when to shift your car. It may be amusing to note that

As a break from the pick and place posts, in this article I’d like to aggregate my research about laser cutters and my experience importing a chinese laser cutter. There’s a wealth of knowledge scattered around the web, and this article won’t meet everyone’s search criteria, but hopefully this will be a resourceful stop for those that are in

Whether engineer, hobbyist, or maker, we’ve happily watched as chipmakers and third parties alike have come to their senses in recent years and cooked up a smorgasbord (smorgasboard?) of low-cost microcontroller devboards – in some cases, very low cost, like TI’s $4.30 MSP430 board. More recently, we’ve seen ARM Cortex kits for $10-$50, the flowering
