So many components involved! I forgot that the bridge needs some Vs across those Ds. This should make things easer than. I need to drive this NCP3065 and the output of this chip will deliver 0.7A.
Thanks very much.

My question was, what happened to uF or mF and so!? I cannot find anything in English explaining "HFK"!
220 HFK. 7WO or
100 HFK. 8L2
Thanks.

Thanks Dave for the board, you might hear from me again.

It's the output of the transformer that has to be 40V DC, 700mA, and 60Hz. So, it the transformer is rated 120Vac/40Vdc at 2 amps than it should deliver the desired effect, correct? Of course if I can find such transformer, most are 48Vdc, 2amps rated. I got some computer trans but they deliver only...

I am looking for transformers:
40V 700mA, 40V 700mA, 10V 700mA, the voltages cannot be below their values.
What determines the output current of a transformer?

My mistake. These are capacitors.

What kind of component marking is this one:
220 HFK. 7WO or
100 HFK. 8L2
Thanks.

I got the PCB and I will send my proper reply.
Thanks much!

That would be really great to have enough etching trays and make some really neat looking cabinets that would display lights or whatever!!! I love that idea!
How much do you sell them for?

You will have my reply once I’ll get it.
Thanks much.

Thank you guys. Yes, I am looking for a blank sheet of it and seemed like there is none.
Thanks.

Would anyone know where to get single sided PCB? I cannot find a single place that can sell that. I can get double sided from Radio Shack but I do not want double sided because I do not need it!
Would anyone know of a source? I am looking for 5.5 x 5 inch PCB.
Thanks.

That’s a good suggestion. I would find out once I would have everything working that something is not completely finished. I found this link and some others: http://www.seattlerobotics.org/guide/servos.html The main issue is the bracket that needs to be attached to the camera to hold the servo in ...

In the article “High Resolution time-lapse movies using a still cameraâ€

I would like to built a fixture for something that could be a cheaper alternative to something that is already out there if I will have enough luck. So, at the moment I would like to avoid going into too many details if that’s OK.
Thanks.
