Re: pin assignments between BOB-10680 and 74HC595

Well, you know most of the pins since it's pretty explanatory. After process of elimination:

SER = Ser_In
L_Lock = RCLK
Clock = SRCLK

Re: How can I debug my 555 timer circuit?

Could I have damaged the resistor, the potentiometer or the capacitors by causing too much heat during soldering (I use sockets for the ICs, so they can't be affected by the soldering)? If that is a possible problem how would I check if a component is damaged? could have damaged a component, sure. ...

Re: Wanted: Hole Alignment Standard

Well, to put it in the simple terms, it's all about the money. To make, let's say a RTC, requires few components but the board would have to be larger thus making it more expensive. Another thing would be accommodating all the common circuits that people use and trying to make a case for all of them...

Thanks!
Yes, although I don't have one personally, I interpret that has being able to use all 10 fingers and it will recognize them individually.

Re: Common shaft couplings.

If you haven't tried yet, I would use Google with search terms like [shaft dia.] and coupler [ing]. Other than that, you could try some 3D printing sites and have them ship it to you. I do have the equipment here to design and print some if your interested.

Re: I need a slot car controller

Have you tried Google to see if anyone else has done this project? If you can't and don't want to do this yourself and learn something, you will have to pay someone.

Re: Simple pcb design project

Pretty much every pcb cad software will export different file types based on your needs. Just need to search what file types are excepte...

Re: LED Dimmer Compatibility Question

Looks like the cheaper will work, but remember the old saying, you get what you pay for. The only thing I am concerned about is the transformer. There is no specs on it. I haven't read the manuals offered at dekor, so maybe read through those and see if they have anything. Or just drop them an email...
