Hi Berni, try to discuss your idea here. Take this Olimex JDM and use your Idea with it.

Someone Electro · 3rd July 2005, 02:07 PM

Lets see thsi is JDM right

I gota write down what PIN controles what:
MCRL: pin 3
Vdd : pin 5
Clock: pin 7
Data : pin 8

This pin configuration works whith IC prog right?

Oh an the idea is to use LEDs to regulate the 12V to 4V (2 2V LEDs in seris)

So the LEDs wont only give an status indication but do a useful job protecting a PIC from 12V

Some serial ports also take 2V on a input as high so this gets rid of an nother transistor.

Il try to get it work whithout even an 5V regulator but using LEDs (how much power dose it nead in programing mode anyway?)

If this works it going to be an realy flashy programer.

It gona be powerd by the port it self.

Whatch out, JDM's ground IS NOT connected with PC ground, but it's on different level. This programmer is JDM based and IS compatible with IC-prog.

Programming current is very low, don't even bother to take it into account.

Yea i know i was trying to find out where ground is.Then i found out that a certan voltage is "ground".

So i need 8 LEDs

I wod be cool to have difrent color LEDs at difrent positins in a semitransfarent box.But im going to go whith what color i find laying around. (probly some normal red,yelow and green LEDs)

The only problem is i dont have an COM port conector. To aculy conect the ting

I am interested if you can make this work

I hope i wont ask my cat for advice what to do it it dosent work.

FINALY you stupid,trublemaking conector shit!!! :evil:

I FINALY got it out of the ruber.Becose the cable out of it only had 3 wires (TX,RX,GND) so i had to rip it out off the ruber.I was redy to throw it out the window! That conector pised me off!!!It just didnt want to get lose.Now to soler the wires to it. (I beter come down before i get to doing it.)
