Also, glad to see you got the bootloader working. Would be a big relief to not have to worry about it going missing in the post!

“There are features that are built-in for trouble-free and safe PC operation. The input power is protected against transients, load dumps and double battery during jumpstarts”.

The DSATX has load dump protection. That is when the voltage at the input goes up to 60 volts because the battery got disconnected and the alternator is still connected. The DSATX has a Transient voltage suppressor that takes care of Load Dumps, and over voltage (double Battery, etc)

The DSATX will operate up to 24 volts on the input without damage. The regulators are designed power to a computer with an 8-16 volt constant input. It will operate down to 6 volts and up to 24 volts though. So If I used M1-ATX marketing, I'd say 6-24 volts, if I use wording I find fare and reasonable, I'd say 8-16v. I'll probably put down 6-24 as the main thing on the spec and then say something smaller for full load. Hmm, what do people really care about?

When you get a reverse voltage, load dump, or way over voltage condition, the Transisent voltage suppressor will clamp the input to 24 volts. If there is enough current, (reverse voltage, or large over voltage) the fuse will blow. This is the same technique I did in the MPBS1, uSDC20D and the M1-ATX and Opus all do this. When the transient voltage supprssor fails, it shorts to ground causing the fuse to blow even faster.

There were only 3 people who recieved the first batch of DSATX'z The rest are going to go out this next week for the others to review.

Say it survives diesel crank

The DSATX is super easy to use. All you do is hook it up to the plus side of the battery, ACC line to a switch or the ignition. And then connect the jumper wire to the power switch of your motherboard. You adjust the pot for 0-20 minutes for the main countdown timer, and adjust the low voltage pot to a low voltage between 10-12 volts. Half way in the middle is the default at 11 volts. That is all you have to do!!!

If you want to do any more, you have to use the serial port. If you get sick of the SDC you can put a jumper on it and then you just have a nice 220 watt power supply!

It is really easy to use.

I recieved all the parts today. I'm going to have these built on wednesday. If all goes well, all 10 will ship Friday.
