Blue Tooth Hat

August 13th, 2006 No Comments »


I’ve had issues with my blue tooth headset. If I turned quickly or tilted my head just right the headset would just slip off, maybe it’s the shape of my ear. Either way it’s an expensive device and I’d like to get more use out of it. So I stripped it down to just the PCB and installed it in a hat I wear often. Check out the Mod !

D.I.Y. iPod AV cable $1.57

July 29th, 2006 No Comments »

After seeing that apple’s AV cable was just a headphone jack and some RCA’s I figured I’d have a cable like that just lying around. I did but it only had audio left and right. For some applications the right audio would act as the video and you’d just get mono audio out. Not in the case of the iPod, it has four conductors on the 3.5mm head phone jack.

These are the connectors Mouser offers.

Here is a good pinout of the different types of 4 cond av cables.

So because I don’t think I’ll use this cable enough to justify the 20 bucks apple wants for their “proprietary” cable and I think its fun to D.I.Y. , I built my own.

Mouse Bot

This is a great starter Robot.

“Mousebot is a simple bot that uses two “eyes” to sense light and then turns towards the light. A single large “whisker” is mounted on the front of the mouse to detect collisions. A collision with a wall will cause the mouse to reverse and turn then take off in another direction. This project is pretty cheap, if you have a mouse to use the other parts can be obtained for less than ten dollars.”

Using his Sprint Sanyo 4900 and a USB data cable, Pat can access the internet any where he has sprint service. Good going Dad!

If you’d like to do the same this is what you’ll need.

Phone: sanyo 4900 or any other sanyo

Cable: I’d check eBay for one that charges while your connected.

Drivers direct from Sanyo

Once you have your cable and you’ve downloaded the drivers just connect the phone, windows will prompt you for the drivers.
Direct the windows prompt to the correct drivers for your phone. Then you should see a “usb modem” installed.
Next go to your network connections and “add a network connection”. The number to dial is #777 (this connects you to your vision plan which is a data service, so no analog conversion needed). Your user name is your sprint pcs e-mail e.g. jsmith123@sprintpcs.com. Your password is usually the last four of you social or a password you set up for you vision plan.
Once you’ve created the new connection just connect you phone and double click the connection. You should see you phone dial the #777 then switch to a RX/TX screen. Rx= receive Tx= Transmit. That’s it you’re on the net (or at least you should be). Go have fun, do a few speed tests and enjoy the fact that you didn’t have to buy a $299 pcmcia card to accomplish the same task.

Build your own Night vision camera

December 29th, 2005 No Comments »

Bad Ace Tech Show presents ” How to make a 12 dollar night vision camera from an old web cam and some film negatives.
night vision
Here you have your basic web cam (we found ours on the internet for about $11 US). With a screw driver and a little help from my gerber knife, we got it open.

Get out some old photos, or just get a roll exposed at you local 1 hour photo place.

Buy the cheapest film you can($1 US for 12exp), roll it out; let it get some sun then roll it back up and turn it in. (you now have like 6 feet of IR filters to share with your friends)

Note: The 1 hour place I went to doesn’t charge for film that’s totally exposed. (FREE)

Take a piece of the film that has been totally exposed (black) and use a gerber to cut out a “filter sized” piece

PSP plus iTrip

December 29th, 2005 8 Comments »

This is what happens when an iTrip (fm
transmitter for iPod) and a PSP get together.

psp itrip
 

I got this idea when I was driving around with my wife. She owns an iPod mini with an iTrip.

I was jealous that she could listen to her music via the car stereo and change frequencies on the fly.

She also had the entire FM band at her disposal. That’s 87.9Mhz to 107.9Mhz – over 100 frequencies to choose from.

Now, sure, I could go and get an FM transmitter to jack-in to my headphone jack, but then I’ve got this cumbersome thing hanging from my sexy PSP.

One idea was to gut a generic FM transmitter.

Most of those have switches to change the freqs, and I’d have to make a place for those switches on the exterior of the PSP.

That would take away from the clean look of the PSP

The plan is to marry the two so that the PSP still looks like a PSP, plus maintain the ability to change freqs on-the-go.
