Fresh hacks every day
Most of what people call batteries are actually cells. All of the common disposable alkaline batteries from AAA to D are single cells. The exception is the 9v battery which actually has six smaller cells inside of it. [Tom] took a look inside three different batteries to see what cells they're hiding. Since he no longer uses the batteries for their intended purposes the individual cells may find a … [Read more...]
To the casual observer this flower looks nice as its illuminated center fades in and out. But there's hidden meaning to that light. Some of the blinks are longer than others; this flower is using Morse Code. [Renaud Schleck] wanted to try a few different things with his MSP430 microcontroller. He decided on an LED that looks like a flower as it will be a nice piece of decor to set around the … [Read more...]
Adding some lights to your everyday items will certainly give you a style leaning toward the world of Blade Runner. But if you can add functionality to control the blinky components you've actually got something. A great example of this is [Kathryn McElroy's] Chameleon Bag. It's a shoulder bag with a light-up flap. It can color match your clothing, but she also built some features that will let … [Read more...]
[Dino's] kitchen skills match his hardware hacking prowess. Look really close at the image above and you'll realize this collection of transistors and passive components is edible. Rather than decorating cookies for the holidays he built this audio amplifier from gingerbread, icing, and candy. The thing is, [Dino] almost always has that extra touch to his presentations. If you watch the video … [Read more...]
[Cunning_Fellow] published a post with three proof-of-concept approaches to driving a WS2811 LED pixel. We looked at a project early in December that used an AVR microcontroller to drive the RGB package. [Cunning_Fellow] saw this, and even though he doesn't have any of these parts on hand he still spent the time hammering out ways to overcome the timing issues involved with address the device. His … [Read more...]
The work which [Mark] did to mount this iPad mini in the dashboard of his Ford truck is commendable. It looks like it came from the factory this way, and the functionality matches that illusion. He actually started the project before he had the iPad mini on hand. A PDF that mapped out the exact dimensions was used as a template for the layout and alteration. He took the stereo controls out of … [Read more...]
[Hailrazer] over on the Made by Bacteria forums was a bit tired of all his consoles cluttering up the space underneath his TV. No worries, though, because it's actually fairly easy to combine a Gamecube and an N64 into one system that looks very professional. While [Hailrazer]'s Gamecube was left reasonably complete, not including the addition of a mod chip and SD card to hold Gamecube disk … [Read more...]
