It's been a LONG time since I did any soldering.  I was doing fine on the $50 robot until I got to where I needed a 3rd hand for tying in the ground wires!  LOL  I'll step back and do a little practicing :'(

well you dont need a 'third hand'. couldnt you just as easily tin the wires and then just mount on top of the connection and melt? im guessing this is for the power buses? i am going to have a go at this one today as well, the only thing i dont have for the $50 board is the atmega chip. (no where here stocks it) :( anyways good luck with the soldering!

solder iron = 1 hand
solder = 1 hand
holding wire in to board = 1 hand


total = 3 hands  :o

I have a third hand tool for things like these, theyre only like $6 and they come in real handy.

Also my secret to holding difficult components and wires in place during soldering is blu tac. It comes straight off aswell..

Don't get a third hand, theyre garbage in my opinion and can scratch your pcb and possibly cause a short.

I would get a pcb vise!! (i have the panavise jr, its amazing)

Let's change the math a bit...

solder iron = 3 fingers
solder = 2 fingers
holding wire in to board = 1..2 finger(s)

That leaves 3..4 fingers for nose picking - and let's face it... You've only got two nostrils, so you better ask a friend over to "help"  ;D

yes but soeren, assuming that wasnt sarcasm...how many people do you know that can solder, hold the wire to the board and pick their nose?

i do that in if its in the middle or to hold down header pins. if theyre on the side i use my improvised helping hands.

Blu-tack or electrical tape sounds like a great idea!

what I do is "two-man soldering".
I do the iron while my dad does the solder and wire.
It works really well

Hi,

"sarcasm" is a strong word for a bit of humour, I'd say.
Well, perhaps don't pick your nose with the hand holding the iron, you might loose an eye  ;)


You could use a similar method to the way it's often done (holding components in place for soldering) in hand assembled circuits in industry:
  • Load the components into the PCB
  • Place a piece of foam "rubber" over the components, perhaps using elastic bands to hold it.
  • Turn PCB upside down an solder (bending and cutting wire ends first).

Scotch tape works great to hold components in while you're soldering them in.

Hi,

You actually tape down each component before soldering?
Scotch and 3M must be thrilled ;)
