Re: [time-nuts] Trimble Thunderbolt NMEA ?

Tim, It shouldn't be too hard to modify the code for my Thunderbolt monitor to make it into a TSIP-NMEA converter. The last version of the kit has a uC with two serial ports. I m out of the kits at the moment but I have a few spare boards left over. Don't have time to write the code at the

Sparkfun is selling a board (around $15) based on the STM VL6180 chip that measures distance based upon time-of-flight of pulses from an on chip (or at least in-package) VCSEL IR laser. Claims to have a range of 0 .. maybe 30 cm. Unfortunately it doesn't look like you can directly access

Hi Angus: Do you know if they have an IR pulse front end which would be more interesting than the ultrasonic front end? Mail_Attachment -- Have Fun, Brooke Clarke http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html http://www.prc68.com/I/DietNutrition.html Angus wrote: In
