I built it and it worked fine. It sat on my workbench for a few months.
I tried it again and it worked again. I then disconnected the power, then connected again, then it stopped working. I noticed that VR1 was getting hot, very hot. Since then, it does´t work VR1 still gets hot.
Does someone know the problem?
Remove IC1 and IC2. Check regulator. Make sure you get +5V at output. If not, replace regulator. Replace IC2 (timer) . Check +5V. If not present, replace IC2. Finaly replace IC1 and check operation.
Everything went okay until the last step, Ic1 is bad I guess.
Thanks.
oh yea, where can I get a new Ic1?
Please return defective IC to:
Velleman Kit Tech. Dept.
Legen Heirweg 33
9890 Gavere
Belgium
Can you send me an email and tell me what the new controller will cost?
Thanks,
Wayne
Sorry, we are not familiar with international shipping rates and taxes. Still, we think it will not be too much, far less then a new kit we would guess.
Thanks. I will most likely send for a new one. I live in Germany.
I only need the price for the controller. At a popular electronics store
here, the offered thr price of 25 €. That´s a bit much for me, cosidering
the whole kit was 50 €.
Thanks for your reply…
25 euro is rather expensive. Please return your assumed defective processor with proof of purchase. If it is less than 2 years old and if we do not notice any abuse, it might be exchanged under warranty conditions.
