New Jarduino build gets started

Hmmm, braided copper solder wick, good to know. I had a devil of a time trying to get that sucker off there. I kept trying to tell myself, "well at least you know your soldering is good!"

Do you just use any stranded copper wire (I'm assuming prepped with flux) or is there a specific product you get? I do have a desoldering pump, but go figure, I only remembered it after I'd finished.

Looks like this:

It's also called desoldering braid. Desoldering pumps work kinda "meh". The braid works like a sponge and sucks it up real quick. It's way less cumbersome and fussy than than the pumps. The day I discovered this stuff I tossed my desoldering pump in the bin (actually it was first disassembled for useful parts, then binned

).

The solder wick comes on a roll
It looks similar to braided ground straps on older cars
Very handy to have on hand, but I've always got by with a solder pump

Nice work so far

Edit: I'm too slow

Sweet thanks guys. I'll see if Lordco or The source has some kicking around here for next time, because I'm sure there will be a next time.

The Source Pacific Rim Center shows 2 in stock

Hey, thanks Greg! I haven't been up there yet, but now I definitely have more motivation

I got some more goodies in the mail today. A ribbon cable for the LCD screen. I want to mount it in the hood so I don't have to open the cabinet door to see the screen.

And the 4 driver LDD mounting boards:

And thanks to Chatouille, I now realize I ordered the wrong PCB board terminals for the boards and I'll have to buy 3.5mm pitch blocks rather than the 2.45mm I have coming. Du'oh!
Good thing I only paid $1.5 for ten and free shipping.

Hey Dom,

Which of the RC guys did you get your boards from? I'm thinking I might try to grab one as well. Make sure you connect the PWM signals to ground with 10K pull down resistors.

I'm excited to see your build!

Do you mean to use the pull down resistor in case of power loss to the controller? (so that the LED’s don’t go to full power?) From what I’ve read, if you remove power to the arduino, the PWM output is already held low, and the lights will not come on. It would be a great safeguard if the physical connection is lost though, and very easy to add to the LDD boards.
