Wireless Temperature Control for a Microbrewery

Wireless Temperature Control

When brewing your own beer, temperature control is important. If the temperature isn’t regulated correctly, the yeast will be killed when it’s added to the wort. It’s best to cool the wort from boiling down to about 25 C quickly before adding yeast.

To do this, [Kalle] came up with a wireless temperature controller for his home brewing setup. The … Read the rest

Remote control command center includes RF and IR functions

all-in-one-remote-relay-includes-RF

We’re still not quite sure what to call these projects, but as we’ve said before, it’s a pleasure to see what people are doing to use one remote control to rule them all. The project being developed by [Kalle Löfgren] seeks to simplify the remote controlled items in his home by combining all control into one smart phone app. The … Read the rest

Tool box light dimmer helps out a friend, offers up design tips

[miceuz] has a friend that works as a theatre technician, and in the course of his job he often needs to jigger with various stage components while shows are in progress. As you can imagine, the lighting situation is far from ideal, so he asked [miceuz] to build him an adjustable lighting solution for his tool box.

The circuit itself … Read the rest

Bitbuf delivers some of the best chiptune effects around

Wow. And furthermore, WOW! Just looking at that clean prototype you know that a lot of work has gone into the project, but when you hear this chiptune MIDI device you’ll really be impressed. We know what you’re thinking, but really, you’ve got to hear this to appreciate the quality [Linus Akesson] achieved in this synthesizer. You can catch it … Read the rest

Reverse engineering a cheap LED message marquee

[Hugo] went all out when sharing his findings while reverse engineering this small LED marquee. He purchased the 29×7 LED matrix for under $12 but was surprised to find that the USB connector wasn’t a standard type and didn’t come with a cable. He first soldered a standard connector in place and then set out to make the device do Read the rest

Exploding an AVR

Unfortunately [manekinen] wrecked a couple of AVRs during his tinkering. Not letting this get him down he decided to blow them up to see what would happen. In exchange for their precious magic smoke the AVRs revealed a good portion of their silicon die.

While the details are a little sparse it seems like he hooked them up to … Read the rest

Flower with PCB pot and LED blossoms

[Johannes Agricola] recently held a workshop at the Peace Mission in Goettingen, Germany where he shared his RGB LED flowers. The small round PCB hosts an ATmega88 microcontroller which is running the V-USB stack so that the unit can be controlled by a computer. Each flower blossom is an RGB LED connected with four enameled wires which, when twisted … Read the rest
