Re: Beheaded fatty nail as soldering tip...

Yes, the bare solid copper tip has to work well, but where did you find/get/source pieces 4mm diameter solid copper wire ? Less diametre is not stiff enough.

I will have to check the nearby metal supply store for 4mm copper rods...

Beheaded fatty nail as soldering tip...

:shock: Very cheap soldering pencils use a tip that is nothing else than a rod held by a set screw. A proper tip has a copper core and iron plated. For not precision temperature work, like salvaging components off boards, what is the inconvenient on using a nail properly ground to chisel shape tip ?...

Re: Line Array - Anyone have experience?

Nice project. Do you prefer individual amplification for each driver or a series-parallel array fed by a single amplifier ? I would go with the single amplification; done it a few times that way. And no dedicated power supply to the speaker, less parts to give trouble. The old Bose have a 3x3 array;...

Very well said, CeaSaR. :smile:

So Postimage, eh ? If it works to link public images to public forums I may save them there; as 'Photobucket' used to be. Now, with 'Dropbox', got hurdles too.

Re: HEY Dacflyer! GIANT LED DISPLAY!

Suspected that they would want viewers to sign up... It is all about controlling you. I cannot even attach a screenshot of the red message "Sorry, the board attachment quota has been reached." when I try to attach a picture.

Re: To evaluate performance of used 18650 cells...

Thanks, Len.
All that makes good sense. I did not take in account the cost of cells; just saw the frustration of picking a bad cell from a bin of charged ones that some do well and others not at the moment of need.

To evaluate performance of used 18650 cells...

A bunch of old, used, salvaged lithium cells of unknown capabilities. Need a load scheme to evaluate their condition. Like loading them at a certain current load for 1 minute; another load for 10 minutes, another for one hour. Measuring the voltage at end. Perhaps checking voltage recovery after a c...
