Fresh hacks every day
This is the control and monitoring hardware which [Jack] built for his campfire electricity generator. He’s done an amazing job to get this far. You can see he’s pulling 1 Amp at 14.2 Volts off of the system. But there one gotcha that’s still plaguing him.
The rig uses a big metal plate as a heat sink over the … Read the rest
[Jason] has been hard at work on this Arduino-based low-res gaming platform. He even had a fab house deliver circuit boards to pull everything together. It’s a little small in his hands, and the graphics are limited to the 8×8 pixels provided by the display. But it still looks like a lot of fun and the code was written … Read the rest
We’ve come across extremely expensive photocopiers that also fax, scan to email, and generally have too many features to list. [Eduardo Luis] figured out how to implement some of this type office magic using very inexpensive components. Specifically, he can press one button to scan a document and send it to an email address.
The user controls patch into … Read the rest
It seems like something out of The Red Green Show but this motorized stargazing chair is a serious piece of astronomical hardware. It has a shelf that places a set of high-power binoculars directly in the user’s line of sight. The elevation is easy to adjust. And a power drill lets you take the whole thing for a spin.… Read the rest
Kudos go out to [Jose] for his work getting so many different components to talk to each other in this Arduino weather station that using a Raspberry Pi to display the data online.
The components shown above make up the sensor package. There’s an Arduino with a custom shield that interfaces the barometric pressure sensor, real-time clock chip, a … Read the rest
This is the back side of [Dmitry Grinberg's] 8×8 LED matrix pendant. He had seen the other projects that used a 5×7 grid but wasn’t really satisfied with the figures that can be drawn in that confined area when each pixel has only the option of being on or off. His offering increases the drawing area and includes the … Read the rest
For those of you that can’t make a decision between buying an Arduino and a PIC processor, [Brad] has come up with a novel solution, the PICnDuino. We’ve featured him before with his [Retroball] project, but this time Brad has been full funded on Kickstarter, and is pre-selling boards for delivery in March.
[HAD], specifically I, was fortunate enough … Read the rest
