New UIRT2 hardware ready

[oe1k]

I'm still willing to make up a batch of single-sided PCB's at the EE lab on campus for free and help coordinate kits. I'll watch here for PCB.

I've been looking into a SMT version too, but how do you then program the PIC ?? ops:

Further I think the new PS2UIRT is more user friendly since no internal wiring is required. I'm still not sure how to make the present UIRT2 work with the internal WOL connector . This would however still be an alternative.

One question though, the switch on RB0 is it a toggle switch or a push button with pullup or pulldown?
I tried to use RB0 with a pushbutton but the input oscillated alot, when it was floating.

A simple pullup (or down, i can't remember which way round its set up) resistor will solve this.

OT: Do you have a web address for "the ir-X from Applied Digital" mentioned above?

Thanks. If they aren't being manufactured anymore, this would be less attractive. At least from MY perspective.

Just remade my uirt to the new schematic (on breadboard) and it seems to all be working fine. Not tried the programming yet but using the darlington driver definatly seems to have improved the tx range.

Cheers,

these 2 I know, but I've never used them (since I don't know how to make the files ops:

I'm interested. I haven't stayed on top of the whole UIRT development at all, but if the PS2 schematic in the other thread is this same UIRT then it looks like a quick home-etch and $10-$15(US) in parts would do the trick. Jameco has the 16F84 (4MHz) for $6.

UIRT2 looks great! Just what i need for my HTPC.

Just one thing..
I've got a Asus A7V133-VM motherboard. (MicroATX, Athlon or XP). WOL and WOR connectors seems to be very expencive stuff, because Asus have left them out on my board. (They are mentioned in the manual, and the soldering points are there, but no connector)
Therefor I have to use the power button method for UIRT power-on.
I don't know how my MB does this (negative or positive voltage), which pin is ground and so on.
Is there a failsafe way to do this?

Your friendly moderator here: start a new thread for new questions. Long threads tend to be very confusing and non-informative. I'll lock the thread if it goes on for much more with off-topic questions, nothing personal against anyone, just trying to keep it 'neat'.
