I am in quick need of 3 total unbuilt kits with cases. Since Scott is out of town, I don't think there is any way to get any until he gets back. Does anyone...
Hello, I just got my OT a couple of weeks ago and scott already did the 1-wire mods... "a 680 ohm resistor between JP4 and JP8, and solder a wire jumper from...

Sorry, this is a bit off topic. Anybody else have trouble getting e-mail through to n1vg.net? ... Reporting-MTA: dns; LT2-500 Arrival-Date: Mon, 22 Aug 2005...
Ack, that's not good. Try it now - I think I got it fixed. The new server didn't have the 'sales' alias for some reason, and was passing it on to the old...
My OpenTracker arrived and works with GPS. I'm ready to roll it over to the Ultimeter configuration to work with my weather station. Three questions: 1. I...
Does anyone have a schematic/parts list for using a FET to power the radio on/off to conserve power? I'm contemplating getting a cheap Yaesu VX150 for use with...
... Yea. Someone on this very list came up with a nice circuit. I drew it up in a schematic capture package and gave it part numbers. I can send you an...

... Yes, it should work with the latest version. Make sure you do a full load, and that you don't keep any configuration data. And yes, you can roll back ...
... Yea, me too! Hey, when I find it, I'll see if I can post it. -- Curt, WE7U. APRS Client Comparisons: http://www.eskimo.com/~archer "Lotto: A tax on...
I've had several email conversation with Jim, the guy who sells these.. The 35Amp rating is a bit over optimistic, IMHO. More like 8A continuous.. but for...
... For through hole designs, I use the 2N7000 or BS170 FETs a lot. I'll have to see what it is I'm using on my solar powered weather board - it was some ...
... I have one of these units in my Jeep. Works great for that application but I don't think it would work for extremely low-power situations. What I...
I was doing some power calculations for a similar circuit, and came up with some outrageous trace sizes needed for handling 20 or 30 amps. I suppose it'd help...
... I'm starting to recall some of the details now of working on this project. I was interested in a mobile radio application, so I needed high-side switching...
... I took mine out of the case, popped off the two red wires, and put a couple of #10 wires on there, just to avoid voltage drops. Had to bore out the holes...
I agree, if you are doing low power work, this may be overkill. I have also found you need a good 1 or 2 seconds of time BEFORE you transmit or receive, just...
Great thanks - got it. I had to re-download most of the files from CVS, but I am now able to compile a complete build. This weekend I'll try it out. What's...
... Nope, the only way to kill the bootloader is to execute a bulk flash erase command. I'd have to check the datasheet on how to do that, but it's not ...
As far as I can tell, looking at the datasheet, the IPS5451 is nearly a one-part solution. Its a high-side solid-state relay, looks like I connect the control...
