Fresh hacks every day
Here's a weekend junk bin project if we've ever seen one. [Pat] used a quartet of computer fans to make his laser Spirograph. Deciding to try this simple build for yourself will run you through a lot of basics when it comes to interfacing hardware with a microcontroller. In this case it's the Arduino Nano. The Spirograph works by bouncing a laser off of mirrors which are attached to the PC … [Read more...]
This quick and easy evaporative cooler might be just the thing the next time the air conditioning goes on the fritz. [Stephen] saw an eBay listing for a personal air conditioner that used a moist sponge and fan to send some cool relief your way. But he wanted to run his own test to see if it really did anything before laying down the cash. The idea is to run air past a moisture source. Some of … [Read more...]
At first we thought that [Brandon Dunson] was writing in to tell us he's too lazy to fix his bathroom fan. What he really meant is that simply replacing the unit isn't nearly enough fun. Instead, he developed his own bathroom fan trigger based on stinky or humid air conditions. He didn't publish a post about the project but we've got his entire gallery of build images after the break. The … [Read more...]
We have no idea how well this diy fume extractor works, but it sure does look great! We've been thinking that it's time to stop trying to blow away the solder fumes while working on project and this might be just the kind of motivation we need. The 6" cube doesn't get in the way of your work, and since it includes a carbon filter it should keep the smell of burning flux to a minimum. [Jeff's] … [Read more...]
Start your week off with a smile thanks to the video [Sammy] put together. It shows off the cooling rack he made for his network equipment. The project was developed out of necessity as the summer weather was causing his modem and router to heat up and at some point one of them would just shutdown and refuse to work again for hours. We haven't run into this ourselves but it's good to know that … [Read more...]
[Styropyro] did a great job of taking common parts and making an interesting item. He calls this his Tornado lamp, and it's made with stuff you probably have around the house -- well you might have to substitute more common glassware for that Erlenmeyer flask. The bulk of the hack is in the base. You'll find a laser diode pointed at a small scrap of mirror. That mirror is mounted on the center … [Read more...]
The fan motor on [Pete's] oscillating tower fan conked out on him. It's a shame to throw away the whole thing, but it's near impossible to source parts for a small appliance like this one. So he set out to rebuilt the motor and get the thing working like new. The motor in question is of the brushless AC variety. [Pete's] gut told him that the failure was due to bad lubrication of the bearings … [Read more...]
