I'm looking for a bare bones bluetooth module for use in a wireless H.U.D. I'm trying to rig up. Can anyone recommend a solid, decently-priced component and where to get it?

Nope. Been looking for one myself.

What are you building??

Here is a site where a guy documents a build where he uses a BT transmitter/receiver:

http://zedomax.com/blog/zedomax-diy-113-build-a-bluetooth-controlled-holloween-hovercraft-party-light/

Has some good programming information, some code, interfacing, schematics etc etc....

Enjoy.

Here is the bluetooth transceiver they used:

A LCD microdisplay that serves as the heads up display for a wingsuit avionics suite.

Coupled with a GPS to derive ground speed? forward speed? way points and what not?

Funny you said avionics.... thats what I do for a living...

Yeah, I'm going to tie a Win-tec WBT 201 into a Palm Tungsten E2. The inital plan is to code up a simple program that will strip some basic data from the 201's output and formulate it into a simple compass/speed/altitude display to pipe to the LCD. This is assuming that I can extract data from the 201 in real time. If not, then I'm going to play around with some GPS receiver modules to rig up what I need.

Ideally, I can get it all working and fitted into a small, clean box that bolts where a camera mount would go on my RatHat. My preference is to make the lcd wireless so that if it should get caught on a riser or something, it's not phsyically connected to my helmet by anything but some plastic screws.

Either way, wouldn't it still be "pull time" ?

You can try Ezurio a UK company I have used them in projects. There are others but I can't comment on quality as I haven't used them.

Except for the HUD, you describe an applicattion I build last autumn. It uses audible feedback and was discussed in this thread.

pocketParalog - a Java ME application which will run on Mobile Phones, Pocket PCs and Palms (The later two with the free IBM Java implementation). I have tested it on my Nokia 6230i, Palm Tungten E2 and Dell Axim 51v.
- It supports Bluetooth GPS (serial as well if you can get an adapter, which will probably be a PITA) delivering but the basic NMEA sentences.
- It records the raw data for later replay and/or import into Paralog.
- It can store a waypoint and set the ground level (GPS returns MSL, Not AGL!)
- It displays real-time information for altitude, horizontal, vertical and 3D speed, glide ratio and of-course and distance to the stored waypoint.
- Speeds, distances and bearings are calculated using the sophisticated algorithms used in Paralog.
- It has a 'Vario' function for speeds, glide ratio and of-course to waypoint (to help you get back to the DZ when in low visibility conditions or flying on your back). Center and range for the vario is user selectable.
- It can sound three freefall and three canopy alarms (user selectable).

Right now, I consider it more a proof-of-concept than an appliation and I is free for anbody to try. PM me if you are interested.

The phone/PDA fits into a jump suit pocket and the WBT-201 is mounted on the back of my helmet. (See this post for details on mounting the WBT-201)

May I have a copy of that application? I'd like to test on my BlackBerry which supports Java (J2ME/MIDP 2.0/CLDC 1.1). I am also a software developer myself, by the way... I program software for BlackBerry for a living.

Because I am deaf, I can't hear the noise that I make while I am tracking and adjusting - so tracking is more of a trial and error by feel alone and watching landmarks below me. So I definitely have a use for GPS logging to practice tracking and getting better at it (because I am aiming to specialize in bigways...)

I'm considering a Bluetooth GPS logger, and am aware of the WBT-201 that works with skydiving, but I'm also interested in the QStarz BT-Q1000 because it has 5 Hz update capability (streaming over a Bluetooth connection). Webpage here. Does anybody have experience with 5 Hz logging during skydiving? How well does 5 Hz work?
