Still haven't posted an updated version, but the next one will also include a bootloader update. This actually reverts a change I made earlier in an attempt...
Scott, you mentioned PLC logic a couple of weeks ago... we have a balloon we want to launch and would like to send a message to the T2 to use the hi side...
A bounding box (coordinates giving two corners) would be very easy to implement. I won't have a generic way to do that for a while, but I can do a one-off...
Maybe in 4 to 6 weeks.. no definite word yet. I'm just brainstorming (and double checking ideas w/you) before presenting them to the balloon guys... better to...
I've had several requests for a geofencing option like that. Any suggestions on how to safely disable a car using the high-side switch? I suppose a brute-force...
muhhhhahaha..... I like that.... semi permanent disabled. But the "must have" accessory would have to be the ejection seat. What would really be fun would...
I learned the joys of NC and more complicated relays at a young age - tore apart a whole pinball machine to build all sorts of stuff with 'em, and nearly...
Ok, latest version is posted. I dug up a revised version of the FSK modulator I wrote for the OpenTracker around the end of 2004. It never worked right and I...
... Are there two hardware PWMs on that chip ? Wondering if there is a neat way to "choke" the PWMA by dc from PWMB. Increasing component count, tempco...
... How about shorting the switch to car horn ? An 'indirect' more than 'benign' method. Customs officers ought to know about morse, and act when the mercedes...
There are, but the other one is used for clock recovery on the receive side. If I wanted to use an extra I/O pin, I guess I could switch it between hi-Z and...
The "geofences" might have a use as report triggers (or blockers!); circling closed garages and any other black holes. Little reward from lots of cpu cycles,...
Actually, for rectangular areas that are orthogonal to the coordinate plane, there's not much processing involved. Each GPS coordinate is already converted to...
Perhaps defining multiple orthogonal areas? A 2 point line suits me ... or a parallelagram... If you look at the coast of SC, it runs approx 45 degrees to the...
... IIRC, Scott mentioned support of great-circle distance calculation. If that will be scriptable, many local contours could be approximated using distance to...
I'm hoping to finish up the next revision of the through-hole (OT2m) board soon and get it submitted in the next couple of days. I think I've fixed all of the...
Yes, in the KPC-3plus's DB-9 radio connector: 1 TXA Transmit audio (AFSK out) 2 XCD External carrier detect 3 PTT Push-to-Talk 4 CTLB (AN0) Control line B (ANO...
Mute pin can be allocated in the kpc3 software to two pins.... pin 8 and I think pin 4. I use pin 8. Pin 7 is power. Pin 2 is XCD. I like the idea of a...
... I'd really like to see both of these capabilities. The feature I'd like most would be to have the GPS or the KISS port on that 2nd interface (don't care...
I'll second Curts request. I'd love to see one serial port for GPS and the other for TNC (KISS or otherwise). Then, if we had the GPS sentences (maybe just...
Getting the second port to work for GPS should be pretty easy. KISS too. I think the console will probably be confined to one port for simplicity. I'm going...
... There's not a ton of space left on the board, but a 2N7000 might work as a cheap low-side switch for a couple hundred mA. Actually, the first SMT ...
I kind of lost track with the thread, but are you looking to put both serial ports on the same physical DB9? If so, no big deal, we can just make up a Y cable...
