DIY Spot Welder

at 6:00 pm. Filed under DIY Hacks, Electronic Hacks

 

Using a transformer for an old audio amp and a case made from an old computer power supply sure does make for a good looking DIY spot welder. It also has some smarts built in to detect when the welding electrode has been lowered to allow for a slight delay before the welding power is turned on. A pot is adjusted to change the actual weld time so you can get it dialed in and produce consistent welds. Manekinen says that it can weld 2 x 0.75 mm sheets with no issues. A BT138 triac is used to switch the power and seems to be holding up but Manekinen would recommend using something a bit beefier if you decide to give the build a try.

Automated Dartboard Score Monitoring

at 3:07 am. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks, Game Hacks

 

Dan sent in a cool Automated Dartboard Score Monitoring project that he just completed. It is based around a dartboard that already has a ton of smarts built into it. The cheap ($15) dartboard has built in sensors that can detect what score area was hit and keeps track of the score on a built in LCD screen. How can this system be made better? Well you could install a high performance CPU and transmit the scores to an Android phone! I had never heard of the Coridium BASIC Chip but it looks like a fast, powerful device for $10. The sensor wires were connected to inputs on the Coridium chip and the resulting hit locations are sent via a Bluetooth module to an Android device running custom code. If you want to play around with the code to see how it works you can download it from the link at the bottom of the project page.

Laser Cut Walking Robot

at 4:17 am. Filed under DIY Hacks

 

has built a cool looking laser cut walking robot. It was cut from 3mm plywood which is also a favorite of mine. In the video you can see how smooth the action is. Looks like the built might have taken quite a bit of time since there are a ton of small pieces and each one was connected using bolts and locking nuts. The motor sounds a bit underpowered but that is a simple fix. If you want to build your own or experiment with a similar design Martin has the design files available here.

LEGO MINDSTORMS NXT Pong Game using Wii Nunchucks

at 11:41 pm. Filed under DIY Hacks, Electronic Hacks

 

Matt Richardson has taken some NXTChuck LEGO MINDSTORMS  Wii Adapters and built a pong game out of the NXT system.  I have never had a close look at the LEGO NXT language before, it looks much more robust than I would have expected. As most other platforms have chosen, it looks to be a variant of C. If you are planning on interfacing some nunchucks to your LEGO NXT and have some control over the display screen it would be well worth the time to have a good look at the project code.

Designer Radios

If your last radio was picked up at a department store you might want to treat yourself to a stylish one next time. Check out this Laser Radio by Tom Kipgen from Tom’s Designer Radios. Nothing stock here! The image above shows a consignment job that he did for someone looking for a radio with a James Bond 007 feel.  If you want to see a video of one in action have a look at the Magic Eye model here.

Via: Retro Thing

“This is, in fact, a regenerative radio that runs a very small speaker. The main and tickler coils were wound as honeycomb and mounted in their separate housings on one end of the main tube (2.5” plexiglass). A special housing for a small halogen light and blue filter was machined and mounted behind the coils. “

DIY iPhone or iPod Touch Macro Lens

at 10:25 am. Filed under DIY Hacks

 

If you would like to take macro photographs with your iPhone or iPod you would be out of luck if you have a stock one in your pocket. But if you are like many of us your ever growing junk box of various pieces and parts might come in handy to give you macro capability. Seventeen year old Instructables user Radioactive_Legos has built such a device. He dug out some old scavenged lenses out of his junk box, mounted it in a piece of wood and rubber-banded it to his iPhone. Doesn’t look like much but the results speak for themselves!
