Veroboard- newbie question

[ben]

Hi All,

I am making a LED array with each row to have 7 LEDs joined + to - to +
etc and the appropriate resistor on the end. This row of 7+1 resistor
will be replicated a few times down the board. Postive and negative
wires will run down each end to daisy chain the rows together.

My question is with the veroboard that I have. It has the copper
strips running down the longer length of the board. A single row of 7
LEDs and 1 resistor to fit how I want it will mean that they
'jump/span' across the copper strips. Is this correct or should each
row be running 'with' a copper strip down the board?


Thanks heaps

I'm in the middle of doing a simular project. Best to make your own pcb, or
for prototyping just use perf board and solder leads together of the led's
and wire.
If you need help with the pcb, I may be convinced to help out. My last
board has space for 1280 leds and runs on 140 volts. Email me if you want
help with subject of led.

You may place your parts on the vero board in whatever arrangement
works for your application - just remember to cut the copper strips
where you don't want a connection.

Thanks,

My question is I guess if I want to cut the strips if they run down the
board with the LEDs/transistors spanning over multiple copper strips?

Use matrix board instead. No strips of copper like veroboard, just a
pad on each hole.
You can bend the pins over to make the connections.

YES.

I note you're using google groups [options] then [view original]

Hi All,

I'm no help today, Ben, but might I ask where you buy veroboard from?

I usually get mine from here: http://www.diystompboxes.com/cart/

Just curious if it comes in a bigger size elsewhere. Usually i use
Small Bear pad-per-hole board and just bend the pins over (like lots
have suggested).

thx

450mm x 95mm is the largest Veroboard I've seen.

(about 18"x 3.75")

(local trade electronics supplier)

price seems a little high, but it is the genuine article, not a knock-off.
(and those aren't US dollars)

knock-offs in smaller pieces are about half the price by area.

Bye.
