S-video From An Atari 2600

[Ben Heck] posted this writeup about getting S-Video/composite out of an Atari 2600. This is actually the hack of [Longhorn Engineer], who showed it to [Ben] at a recent event. If any of you have tried to play these classics on a modern TV you may have found it to be quite difficult. If you manage to get it physically connected, through adapters and such, you may still have video issues. This alleviates that issue completely. After you solder this in, your Atari has native composite/S-video. As you can see in the video after the break, it seems to work pretty well.

Lego Head Tracking

[Epoch] Sent in this simple head tracking project using Lego pieces. He’s made a custom mount to hold 3 Lego light sensors on a baseball cap. Then, after modifying his webcam for IR with some floppy disk scraps, he loads up the free-track software and can control his games. For convenience, he has programmed the Lego Nxt to only turn on the lights while he’s holding a contact sensor. You can see it in action after the break. This appears to be very similar to [Johnny Lee’s] head tracking. Judging by the video, it’s not as smooth though.

RF Modem + 250mW Amplifier

April 2, 2009 by Caleb Kraft 37 Comments

[Trax] sent in his writeup on this RF modem with built in 250mW amplifier. The original power of the RF transceiver was around 10mW, his final results after testing were nearly 250mW. He was able to to easily transmit data over 1000 meters using his test setup. He states that he was actually able to achieve this without an antenna on the receiving side. That’s pretty impressive performance. It’s also worth noting that he soldered all of the components in place using a home clothing iron and some soldering paste. That must have been fairly tedious.

Dear Hack a Day,
Websites keep publishing poorly executed jokes today; how can I fix this?

We’ve been getting a lot of questions on the tip line like the one above, so we put together this one-step illustrated how-to. If you’re not the physical labor type, you can use [Steve Lambert]’s SelfControl.

The Dream Tablet

[Matthew] has completed this Dreamcast tablet modification. That’s right, you’re looking at a Dreamcast laid out in tablet format. We’re not really sure what advantages the tablet layout has, since it’s not touch screen and you probably need to put it down to play anyway. The laptop or clam shell might have been a smart choice simply for screen protection. Putting that aside, this is really cool. He had to do some extensive re working of the motherboard in the Dreamcast to get it to fit. Interestingly, he hacked together a custom disk drive for it too. You can see detailed pictures of the entire process, including the construction of the case, on his site. Great job [Matthew].

[Thanks John, via Fusion Mods]

PSP As A Status Monitor

March 30, 2009 by Caleb Kraft 23 Comments

[Avi] sent in his PSP as a status monitor hack(zip). He’s using Lua on the PSP, so you have to install LuaPlayer. The computer side is written in python, so it should be cross platform. Last time we saw a psp as an extra monitor, it had more capabilities, but it was limited to Windows. You’ll find the Lua script as well as the python in the zip file. It’s a nice use for an extra psp.

Vexduino

[Jeremy] picked up a Vexplorer pretty cheap, and wanted to make it better. He decided that Arduino controls would probably be a nice upgrade. He patched into the controller and installed a nice looking plug to interface with the Arduino. He says the software was custom made as he couldn’t find suitable examples on the net. His software is available for download. We covered a picaxe controlled one in January, but it looks like that site is currently down.
