Hi, Hello you in sales? is there anybody there?

Sorry I know this is'ent the place. What about a sales or quires section.
As you did'ent answer my email, here I am.

I recently purchased some items from you, this included some gears GBX023, I still managed to not quite understand your wording, and got a bag of 50 gears all the same size! what good is that to the average robot builder 1:1 =1. A bag of mixed gears including a few worms would be great!! I took the Diasize 60/31 to mean 60mm dia with 31 teeth but it is in fact the other way around... Perhaps I should buy some packs and sell my own little bags of gears, anyone interested!! Going cheap say two of each size + 2 worms.

Other than that I am enjoying my Picaxing! Do you sell? or you perhaps you should sell standard 40KHz Ultrasonic transducers?? used on lots of robot/buggy's.

Just to make this a bit more interesting here's a pic? of my buggy-bot's new IR rear object detector, fairly simple a ICM7555 cmos timer driving two IR LED's at 38KHz via a BC547. A TSOP2438 38KHz detector drives 2 comparators, one suppling the signal to the pic, the other lights the green LED for testing, etc.

I look forward to hearing from you.
Regards

I agree, there needs to be a buy/sell/trade section on the forums. some posters here feel their skills are inadequeate for doing projects they describe, while others come up with neat projects that others might want to buy outright. Also, I bet there are a bunch of guys with spare parts that they wouldnt mind unloading.

I myself am still looking for a real cheap GPS, but still cannot afford to bid effectively with units on ebay.

I myself am still looking for a real cheap GPS, but still cannot afford to bid effectively with units on ebay.
What kind of GPS? all-in-one with display, serial/bluetooth for connection to PC/PDA?

How much is cheap? I bought a Route66 bluetooth GPS on Ebay last year for less than $10 delivered.

Delorme produced two serial GPS units: the TripMate which outputs NMEA data and the EarthMate which outputs Rockwell binary data.

There is one Tripmate on Ebay at the moment with a $1 bid and $11 shipping http://cgi.ebay.com/DELORME-TRIPMATE-GPS-RECEIVER_W0QQitemZ130333910602QQcmdZViewItemQQptZGPS_Devices?hash=item1e5881a64a&_trksid=p3286.c0.m14

There is a lot of info about the TripMate here http://www.bevhoward.com/TripMate.htm

There are several EarthMate serial GPS units available on Ebay for relatively cheap (search term is: hyperformance gps). If you want to write the conversion code, there is info online to guide you in doing that. With the speed of the X2 chipss, it may now be feasible to use an EarthMate GPS with a PICAXE.

Earthmate serial GPS with a $5 bid on it (+ $5 shipping) http://cgi.ebay.com/Earthmate-DeLORME-Hyperformance-GPS-Receiver-w-Guide_W0QQitemZ170387702140QQcmdZViewItemQQptZGPS_Devices?hash=item27abe6017c&_trksid=p3286.c0.m14

Another one with no bids and a $1 start price http://cgi.ebay.com/2003-DeLorme-Earthmate-Hyperformance-Car-GPS-Reciever_W0QQitemZ260484057817QQcmdZViewItemQQptZGPS_Devices?hash=item3ca60f4ad9&_trksid=p3286.c0.m14
