Title: PCB design support wanted
Post by: farsi on Jul 14, 2014, 08:25 pm
Hi there,

I've build a simple LED project last weekend:  https://vimeo.com/100626504

The goal would be to help other beginners to make it easier getting started with LED programming. My idea is to have a jumper switch modes from simple digital pins control vs. control with a shift register.

How much would a PCB design cost? I've some friends in far east, who could help produce these boards at a cheap price.

Thanks for your interest and help.

I could do it for you, take about an hour, $60.
Female header for the LED for direct access,
in parallel with shift register output, with OE control pin selectable between High (disabled) (10K resistor to +5) and GND (On) or an IO pin (for PWM) from the arduino.
Don't even need a switch, just a 3-pin header and a 2-pin jumper.
Keep it under 5cm x 5cm, buy in 10 lots or 50 lots from iteadstudio.
8 LEDs, 8 resistors, female header, shift registers, decoupling cap, and +5/GND/datapin/clockpin/latch/oe.
+5/GND need to be always connected.

CrossRoads answer first, so, I couldn't do anything.

I have seen some of Crossroads PCB designs and can say you will get a very good design.

Thanks all!

This is an exploration type of project, and probably, the PCB can be released to public domain (CC type of license).

Just want to make a very tiny electronic product, to help answer some questions in my head.

Have a good night, and let's keep in touch. Looking forward for the development!
