Fresh hacks every day
This remote control tank now takes its orders from a Raspberry Pi board. Well, actually it’s taking orders from commands pushed to the RPi board via SSH. The control scheme works out quite well. Using a low-profile WiFi dongle the RPi automatically connects to the wireless network when it is powered on. This makes it a snap to SSH … Read the rest
This piece of furniture begs the question, why think of a desk and a computer case as separate things? It combines Ikea furniture with electronic hardware to create the ultimate command center.
First the obvious parts: there’s a nook for the computer case that hangs just below the desktop off to the side, and the twin displays are mounted … Read the rest
If you want to run your Raspberry Pi from something other than a mains power converter, and you’ve got some courage to spare, this hack is right up your alley. [Tom] wrote in with a switch mode power replacement for the RPi’s stock linear regulator. This is the first hack we’ve seen where the RPi’s on-board hardware is being … Read the rest
When we used to use firesticks (the pen style plug-in soldering irons) it was always a worry that we might leave them on. But now we use a base unit which has an indicator light to serve as a reminder. Still, [FoxxTexx] isn’t taking any chances and instead built this timer-based outlet which kills the power automatically.
The parts are … Read the rest
This pleasant-looking plant may try to take your hand off if you’re not careful. The robot flower (translated) includes sensors that cause the petals to move in reaction to external stimuli.
You can just make out the distance sensors as black rectangles on two of the petals. These let the flower track an object by rotating the flower … Read the rest
[Mikey] got a real deal on some A123 Pouch Cells. These are large Lithium cells that tolerate 100A discharge and 50A recharge currents, with 20 AH of life off of one charge. He’s been doing a bunch of testing to find out if the cells can go into an expandable battery pack and be made for use with hybrid cars… Read the rest
Learning to lay out a printed circuit board takes some time. But after you’ve churned out a few it’s really pretty easy. If you find yourself at that point it may be time to learn about more complicated board fabrication. We think a good primer is this multi-layer PCB layout guide which [Rik te Winkel] recently put together. It’s one … Read the rest
