Problem with my Sim Reader!

[megamaster]

I made the Dejan Sim Reader (See Picture Below) but when I plug it in the led don't light!:confused: I have double check the circuit on my PCB Board but it seem to be ok!:( Does this schema really work? :confused:

the circuit is working one.
it is better you use 7805 (5v votage regulator ) than 2 BC239c for regulate the power.

There is 3 "BC239c"! So I have to use 3 "7805"?

NO!!!!!
Use SIMSCAN v2.0, LED power up only, when the software is running....

[megamaster]

I have already tried that! Still the same!

i'm not say you change all the BC239c to 7805 lah.
here,take a look to the schematic i attach here,it is almost same to the dejan reader,just here it use the IC2 LE50ABZ,and dejan use two BC239c and some resistor.

so you just modify your dejan to this.
if you cant find LE50ABZ,you can use 7805

But this one need a power source 9V! Ok I will tried that!

Thank!
