Shipping coast to France

Hi Tea-Bag,

Shipping coast to France for 2 PCB + 2 PRP is $ 6,00, is that right ?

Thank You

Matched LED's

Where do I get 16 matched LED's?

What is the procedure to match them?

See BOM & general instructions. But any generic red 5mm led bag will do. Using a 9V battery and 1k2 protective resistor to feed, and you measure each one's ends for voltage when alight.

Hi Tea Bag

Something was wrong with my payment on 7th of July. I have just made a new payment for 1PCB + 1PRP.

Thank you

Thanks

If you've got that regulator, you could just set it in constant-current mode with 1 resistor, for the current that should be passing trough the leds in operation (Was that 6ma, or am I wrong?). Then you'll get perfect measurements for each led you test.

It takes some doing to read up on these threads.
I havent found any reference to those PRP resistors you're talking about.
How many of those would I need ? Are they 4 bucks each ?

Hi Tea-Bag
I have paid for boards and resistors on July 14.
Can You confirm PayPal reception?
Thank You.

4 bucks for just the signal portion. These are PRP 9372 1/4 watt for audio.
4x 220R 2x 220K 2x 1M. Enough for one board.
