Fresh hacks every day
[Glitch] got his hands on a slew of relays which are meant for use in industrial equipment. They are designed to operate at 24V. He wanted to use these with common microcontrollers and instead of buying a driver he designed and built his own.
There’s a few things to consider with a project like this. You need a power … Read the rest
[Craig Turner] wrote in to tell us about the wireless fireworks controller he just finished building. It has eight total channels and offers the kind of safety features we like to see when working with explosives.
The image above details the launcher side of the project. The project box houses an Arduino which is powered by a 9V battery. To … Read the rest
This board is the start of [Steven Pearson's] quest to automate his home. The module will be used to prototype the rest of the project. Right now it uses an ATmega328 chip running the Arduino bootloader. This connects to one mechanical relay which we would wager is mains rated. The module will be controlled wirelessly via the wireless module … Read the rest
[Steven Mackaay] added a simple user interface that implements a shutoff timer for his desk lamp. His project log comes in two parts, the breadboarding and the actual implementation.
He wanted a few things out of the build. The first is an LED that would help him find the lamp in the dark. The second feature is a shutoff … Read the rest
[Viktor's] found an opportunity to put his embedded design skills to use when the furnace controller in his building went out. He admits it would have been much easier to just purchase a replacement, but not nearly as fun. Instead he built this furnace controller based on a PIC 18F4550.
First off, you may find it strange that we’re … Read the rest
As part of a complete home theater setup [Andy] wanted to be able to control the lights from his couch. He started thinking about the best way to do this when he realized that his TV remote has buttons on it which he never uses. Those controls are meant for other components made by the same manufacturer as the TV. … Read the rest
Late last September, Hackaday along with other hackerspaces including North Street Labs, 1.21 Jigawatts, Maker Twins, made their way to the NYC Maker Faire via the Red Bull Creation contest. The objectives of the contest were simple: build a game in 72 hours, have people vote on it, and join the Red Bull crew in Queens for a carnival-like atmosphere.… Read the rest
