Fresh hacks every day
We’ve seen automated grow boxes of all shapes and sizes, but all were for growing plants. [Jared] over at Inventgeek wanted to do something similar for his algae. He started off with an Arduino-based solution that allows the controlled pulse of LEDs connected to his standard bioreactor as a prototype. Once he determined his proof of concept worked, he … Read the rest
[bongodrummer] wanted to use a lathe to make some gifts for his family. Instead of buying one, he decided to make one and recycle some parts in the process. More info after the break.… Read the rest
The fantastic people at MIT have taken it upon themselves to explain how an OLED works. Their visual aide in this explanation is an electrocuted pickle. This helps describe how OLEDs are actually constructed from organic material. Many of you probably already know how they work, but for those who don’t this video will clear up any questions you … Read the rest

You can buy portable versions, but he realized he had enough parts laying around to slap together a portable one himself. He pulled the inverter from a scanner light and wired it up to a … Read the rest
This Arduino powered DMX controller came along at just the right time. We had shown you a project earlier that involved the DMX system and several commenters remarked on the price to get into DMX hardware. If you happen to have an Arduino around, you can build a DMX controller. He found a schematic for a DMX driver, and … Read the rest
This Clock Knock Block has a bit of everything; milling, Arduino, sensing, solenoids, and plenty of dirty puns. Just knock on the box or on the table right next to it and the time of day will be played back to you in a series of crisp, clean knocks. A big part of the fun here is that the … Read the rest
Everyone loves a good LED matrix hack, and we’ve seen our fair share, but never a 16 by 24 hand soldered SMD one. [bear24rw] and his team needed a project reflecting the interests of one of his classes, being an EE major, an LED matrix was just the ticket. Based on this instructable, he was able to cobble … Read the rest
