I just uploded two pictures of my remote LM335. One is of the sesor, wiring harness and aluminum tube casing, the second is a closeup of the sensor. The foam...
Cool, thanks for the pictures. As a reminder, anyone who'd like to share pictures of their hardware is welcome to. Just put them in the Yahoo group gallery...
I just created an album under "photos" called KD7JYK. I will put my various OT related photos here. So far there are the two photos I posted earlier. I will...
I just uploaded yet two more photos of my completed remote LM335. One is of the entire remote sensor in it's case, the second is a close-up of the tip where...
If I might make a suggestion for the format: The APRS Working Group specification v1.01 includes an "User Defined Data" format that might work well here. This...
Hi Larry, I'm catching up on email and saw that I had yours flagged for follow up still. Can you send me a screen shot of your configuration? I did have a bug...
Hi all, I've added to the photo section of this yahoo group 3 photos of my completed OT. I enclosed it in a Radio Shack project box and added a 7805 to power ...
Cool. I've seen that same Radio Shack box used a couple of times now. Yeah, the 78L05 really can't handle most GPS receivers, at least not without some...
I went to Radio Shack today to look for a voltage regulator and I got a 7805A to power my GPS (GPS wants 5-9v and I'm powering it from the car). It has the 3...
Josh: The package should have shown you what the leads are. Look on the back of the card. Generally, regulators in the common package with the tab on top are,...
Scott, as long as you don't go for a switchmode regulator all linear regulators are equal! It's simply input voltage - output voltage times current........ The...
... I put up some pictures as well as it seems to be a popular thing to do nowadays.. All in all I'm not that satisfied with my first try at boxing up the OT,...
Josh, 7805 has center lead and heatsink connected together. The 2 other leads are input (in your case 12V car) and 5V output. You HAVE TO add two 100nf (=...
Josh, Everything you want to know about 7805's can be found here: http://www.fairchildsemi.com/pf/LM/LM7805.html Later.. Larry "The only reason for time is so...
Josh, The center pin on the 7805 and the tab are common and are tied to ground. Larry "The only reason for time is so that everything doesn't happen at once." ...
I must have missed the original message... you can find a datasheet here: http://www.fairchildsemi.com/ds/LM/LM7805.pdf The tab and ground pin should both be...
But some are more equal than others. =] There are differences in terms of reverse bias and transient protection, and of course dropout voltage and max ...
Here's a guy running a TinyTrak off a single AA: http://www.dk7in.de/TinyTrak_e.html I haven't used that particular chip, but I'm using another one to run a ...
The center pin connects to the 12V ground from the input and the 5V ground for the output. The tab is for connecting a heat sink whick dependingon the...
Build #53343 has been released. The only real change is the addition of a 'PTB2 Output' option. You'll need to download the new config program to see the...
Hmmm.. perhaps a four-character unique code (sort of like a TinyURL) could identify the notification setup, followed by a series of delimited arguments? It...
Ok, I screwed up - the 53342 firmware release got dropped in the wrong folder, and the server was still serving up 53322. It's been fixed. My apologies to...
Hi, Im starting with this, and would like know about any software and how to connect the yaesu 411 to a laptop for recive the information sended by OpenTraker....
Claudio, you will need a TNC and a software to display APRS data. There are many out there to choose from. As a Linux user I can't recommend any Windows...
For receive-only operation, I use a scanner (the FT-411 should work just as well) connected to a laptop's audio input with a simple 3.5mm patch cable. AGWPE...
I have been playing with a SMT (beta) tracker from Scott for a project. I've been able to connect with a computer and set the configuration, and successfully...
