DC Power Station for a lot of Cell Phones?
SpiderWrench has a Maker challenge! “Ok, I really need help with this. I have several prototypes without power, (or rather, I have been forced to use an AC power strip with 30 individual, ugly chargers and a mess of wire everywhere) here is the situation: I need to be able to charge 30 new cell phones on a single power supply. Through some risky experimenting on my part, I have been able to charge 3 cell phones off of a single wall transformer, and I know I need more power to get 30 up and charging. I have thought of using a modified laptop/PC power supply, and I think it will work, but I do not want to risk blowing up 30+ $300 cell phones which are not mine to blow up.” Post up ideas in the forum!

AizeMashehu’s writes “I built two fan controllers into a happy-face baybus for two sets of fan arrays so I can hear the sound of silence while the eight large fans chug-a-lug-lug. One knob on the new fanbus controlls the two rear 80mm fans blowing into the water-cooling radiator (in addition to the existing 120mm fan with rear-mounted speed control knob sucking air out of the radiator from the other side) and the other knob controls the 2 front 80mm fans that blow air around 5 of the fastest hard drives in the machine.

Tom sent in this fun how to from Jared and Dan “The idea for this project evolved out of necessity. Dan and I are both avid gamers. After a few hours of gaming with our normal high-end mouse pads you get a build up of sweat. The mouse and mouse pad becomes slippery and you start to loose your competitive advantage due to the loss of precision. While there are a couple mice on the market that have small fans in them to dry out your palm, they all have major failings in precision and accuracy. So after some thought and discussion we chose to build out our own custom mouse pad with a blower in it to suck the air down through the pad and away from the gamer’s hand. The result is astonishing!” 
Craig guide on PC keyboard interfacing… “Why would you want to interface the Keyboard? The IBM keyboard can be a cheap alternative to a keyboard on a Microprocessor development system. Or maybe you want a remote terminal, just couple it with a LCD Module. Maybe you have a RS-232 Barcode Scanner or other input devices, which you want to use with existing software which only allows you to key in numbers or letters. You could design yourself a little box to convert RS-232 into a Keyboard Transmission, making it transparent to the software.” 
Japala writes “This is the project that I started to do something about these old and outdated mouse pads, maybe to add some more “glow” to them. I bought the plexi from a firm specialiced in plastics. They sell these surplus peaces priced by weight. I found this clear 500x500x5mm piece and payed 45 FIM for it (~$6).” [
Derek Yu writes “Creating pixel art is a skill I picked up because I needed graphics for my games. After a lot of practice, I became rather handy with it, and started to see it more as “real” art rather than just a tool. These days, pixel art is quite popular for gaming and illustration…In this 10-step tutorial, I’ll teach you how to create a “sprite”, which is a stand-alone two-dimensional character or object. The term comes from video games, of course.” [
