Gears Embedded In Business Cards

[vimeo 2395048]

In [Bre Pettis]’s latest “things” video, he talks with [Adam Mayer] about his geared business cards. [Adam] has designed several versions of these cards that have functional gear systems in them. There appears to be a simple two gear one and a more complicated planetary gear set up. The designs have been uploaded to Thingiverse, so you can download and build your own.

Nintendo 64 Crammed Into A NES

[Matthew] sent us this Nintendo 64 stuffed into an NES. He did a great job really, everything looks nice and tidy. the presentation is decent with only the game ports visible on the front to tell you its not stock. The accent lighting on the side vents is not overpowering. Overall this was a really well done mod. Just like the Nintendo 64 in a Wii mod, this only plays Nintendo 64 games. OK guys, lets get some mods going that don’t involve cramming one Nintendo product into another Nintendo product.

Using VFDs As Amplifiers

[HP Friedrichs] sent us this cool writeup on how to use scrapped Vacuum Fluorescent Display tubes as amplifiers. For those unfamiliar, a VFD is a display device common to electronics.  Many have been replaced by LCD, but you can still find them in modern products. [Friedrichs] points out that his 2008 ford has a VFD for the multimedia display.

Since these units are basically tubes, he figured that you should be able to use them as a tube amp. After some testing, he found it to be quite adequate.  The project includes tons of background information on how tubes work, how VFDs work and how to utilize it for amplification. In the picture above, you can see him using one (middle) to amplify a home made radio (right).

Upgrade An Electric Lock Keypad

[OldGrover] bought a Weiser electronic lock. Only 6 months after installing it, the keypad stopped working. Instead of just accepting this, [OldGrover] built a better button pad for his lock.  He decided to go with big push buttons instead of a similar to stock membrane system. After tracing out where the original buttons connected, he attached his new buttons and enclosure. Pretty simple really but it fixed the problem and kept the lock out of the landfill. Now, he has a unique looking keypad on his front door.

PS360 Controller

[Ben Heck] posted his PS360 controller. This is the case of an Xbox360 controller with the guts of the Dual Shock 3 from the PS3. They Dpad is from a ps2. We guess that if you can build them any way you want, you might as well make it exactly how you want it. Wasn’t there a time when everyone laughed at the bulky Xbox controllers? Yes, we know, they’re smaller now but that comic pops into mind anyway.

Gameboy Color On An LED Matrix

[youtube=http://fr.youtube.com/watch?v=-n-iORmV3Qk]

Here is a video of a GameBoy Color being played on an LED matrix. He has built it up to 140×140 LEDs so far and it seems to be going well. He needs to add the final 20 LEDs to get the 160×140 resolution of the GameBoy.  He notes in the comments that he had some problems with dead LEDs in the boards he got from eBay. Trying to remove the dead LED with a hot air rework station resulted in massive damage to the board. At one point he says that the power consumption is 1KW when showing all white. Wow, that’s a drain.

[Kevtris] gave us some more info in the comments with a link to the build pictures in his blog.
