A month ago, we ran a post about [Jim]’s rare and strange transparent microchips. He’s back at it again, this time taking a look at the inner workings of MOSFETs
The Unallocated Space hackerspace is moving, and they’re looking for a few donations to get the ball rolling.
Yes, it’s a Kickstarter for a 3D printer, but the LumiPocket is interesting, even if only on the basis of the engineering choices. It’s a UV laser resin printer, and they’re using a SCARA arm to move the laser around. They’re also doing a top-down resin tank; it requires more resin, but it seems to work well enough.
Around DC or northern Virginia? We’re going to be there on September 11th through the 13th. We’re holding a Hackaday Prize Worldwide meetup at Nova Labs in Reston, Virgina. Sign up now! Learn KiCAD with [Anool]! Meet [Sudo Bob]! It’ll be a blast.
Not around DC or NOVA? This Wednesday we’ll be hosting another chat on .io.
The GEnx is one of the most beautiful and advanced engines in the world, and that means [Harcoreta] oven on the RC groups forums has made one of the most beautiful electric ducted fans in the world. On the outside, it looks like a GEnx, including reverse thrust capabilities, but inside it’s pure electronics: a brushless motor rotates a 100mm, 18-blade fan. He’s hoping to mount it on a Bixler (!). We can’t wait for the video of the maiden.
Open-source Mars rover
[Seth King] wasn’t satisfied with current robotics platforms that don’t work well outdoors. He started the Open Rover Kickstarter with the end goal of having a 6-wheel robot with a rocker-bogie suspension just like the Mars landers. We’re sure it’ll be an interesting platform.
Adding a Flash to a key fob video camera
[doctormord] picked up a key fob “spycam” and was surprised that there wasn’t any onboard illumination. Then again, that would probably defeat the purpose of the “spycam.” A transistor, LED and resistor later (translation), he had a camera with a light. Pics here.
Automated WEP cracking
This is a video of [Elliott] using his autocrack script to crack a WEP wi-fi network. It took [Elliott] less than a minute to crack a network he set up. Lesson: don’t use WEP.
Adding wi-fi to a laptop the fast way
This laptop used to have a broken Mini-PCIe wi-fi adapter. [Mikko] fixed the wireless by taking out the old card and hooking up a USB wi-fi adapter. He soldered the USB leads directly to the back of an internal USB port and used hot glue “to prevent bad things from happening.” A very easy, fast, and cheap way of fixing a broken wireless adapter.
Han Solo’s soldering iron
When [Craig] was 15, he broke the Bakelite casing of his father’s soldering iron. Being a good son, he fixed it by gutting his original Star Wars Han Solo blaster. Nice, but not as great as Starsong from My Little Pony.
Remaking the first video game
At the Revision 2011 demo compo, a museum project called [MEGA] won first place in the “Wild” category with their zero bit recreation of “tennis for 2”. Entirely made of analog electronics, the retro game completes its presentation on a round o-scope screen. You can see a video of it after the break.
Mint-tin bicycle computer
[Alexdlp’s] newest instructable is a attractive and compact bicycle computer running off of an Arduino, and sports the usual bike features. It does not stop there, adding in a 16×2 LCD gives more room for data in both numeric form and bar graph form, and adding in a pair of radio modems allows that data to be fed back home where it can be logged and compared, perfect for the more serious biker.
8085 Reference Card
If you enjoy retro computers, or would like to make your own, you will find this Intel 8085 reference card is a real treat. Based on a original reference card, it has been expanded to give more detail for additional interrupts, electrical reference, T-State timing, and undocumented instructions.
Connect a SNES controller to your Android phone
[Bruno] wanted to be able to use a real SNES controller with the emulator on his HTC Android phone, packing in an Arduino, 6 AA batteries, and a breadboard and mission accomplished! Hardly as portable as the phone, but we commend the “get it done” sprit. Join us after the break for a quick video.

Oven parts scrounging
In response to last week’s post about parts scrounging with a heat gun, Hackaday forum member [BiOzZ] decided to try doing the same thing in his oven. It seems to work quite well, but we’re wondering if there should be any concerns over the lead content of the solder. Anyone care to chime in?
Spill-proof parts holder
Have you ever been in the midst of disassembling something and knocked over your container full of screws onto the floor? [Infrared] has a simple solution to the problem which also happens to keep a couple of plastic bottles out of the landfill.
Easy button stops abuse of the word awesome
Do you often repeat a word ad nauseam? Make author Matt Richardson does, and he hacked a Staples “Easy” button to help him break his addiction to the word “Awesome”.
Cheap Remote-controlled baseboard lighting
[Sean] scored a pair of LED deck lighting kits for a steal and decided to install them into his newly renovated kitchen. They are currently remote operated, but he plans on adding an X10 interface as well as PIR sensors for automatic triggering in the near future.
Yet another LCD recapping guide
It starts with a finicky backlight, or perhaps a high-pitched whine from the back of your display – by now, we’re sure that everyone knows the symptoms of an LCD panel that’s just about to die. [Eric’s] Syncmaster recently quit on him, so he pried it open and got busy recapping. It’s running again, and he wanted to share his repair process in case others out there own the same display.
Powerplant control room panoramas:
There are two power plants presented in 360 degree panoramas here. All those dials and switches just get us giddy. The one pictured above was built in 1918 and is still in operation. Not only are the control rooms here, but several other locations around the facility too.
Energy recycling prosthetic foot:
At first, we thought that this energy recycling prosthetic foot was going to be a power generating device to harvest some energy using our weight in the heel compression. Actually, it is showing off a fancy micro controller based system for reproducing our naturally springy step.
Translating in real time with google:
Google is working on a system to do real time translation of text on your phone. It is integrated into the “google goggles” software which allows you to search the internet using images from your phone. This is pretty cool, but with google translate and OCR being readily available for quite some time now, we have to wonder; why didn’t we think of that?
Exploded images of everyday objects:
[Adam Voorhes] has put together a small collection of exploded views of everyday objects. While they aren’t laid out great for reference, they look good and might make nice artwork in your workshop.
Here’s a quick and dirty kinetic sculpture. It’s a track for a steel marble to roll around in with a magnet on a rotating wheel to pick it up and start it over again. Not every hack has to be a beautiful masterpiece, they just need to be fun. Of course, if this were an incredibly complicated piece it probably wouldn’t have ended up in a links post.
[AlexP] has been involved in the NUI Group and in writing drivers for the PS3 Eye. This time around he’s got eight of them running on one computer at 60fps. Security cameras come to mind but this could be useful in a lot of projects. We’d be interested in seeing what you come up with. [Thanks Kyle]
If you have a problem with folks peeing on your stoop then this is the answer. [Hannes Nehls] put together a urinating-drunkard deterrent by placing a humidity sensor in the (achem…) trouble-spot and a small tube above. When they pee on the sensor, it pees right back on them. Video available if you click through to the link.
If you’re a little shaky when it comes to understanding and working with amplifiers this tutorial is for you. It’ll walk you through the basic concepts, then apply that knowledge in a simple op-amplifier circuit.
It’s always nice to end a links post with something creepy. These faces are made from a cast of the artist’s face. They sing a trio of nonsense and it’s the life-like movements combined with the obviously mechanical backend that tingles our spine. But they’re really just a novelty and not the real thing.

Everyone Remembers Free day right? [The Ideanator’s] Bus Pirate came in such a nice red box – he decided to make it his permanent case.
[Chico] is in the middle of making a CNC, but decided to make some music with the steppers in the mean time.
What looks like an old wooden box is actually [Ludvig’s] super sweet retro arcade cabinet. Complete with a giant emergency stop red button.
Who says Legos are dead? [Carl] used them to create a simple and cheap diffraction grating projector. Including video!
[Torchris] used an Ethernet shield exactly as it was designed, sending data over Ethernet. Still a nice hack for those needing help working with Ethernet shields and Arduino.
Finally [Robert] let us know about a friends Arduino Binary Clock. But we think his elegant use of tape and a sand blaster to engrave glass is cooler.
