Re: Beheaded fatty nail as soldering tip...

Hi Al. How much erosion brass, bronze tips show compared to copper ? With an iron nail, erosion should be minimal, stiffness great, But of course slow heat conductivity that calls for fatter and shorter tips to approach a reasonable performance in certain uses. Remember trying a gold clad tip when l...

Re: Beheaded fatty nail as soldering tip...

That grounding wire... Good ! A foot will make maaany years of tips. Iron cladding not needed for longevity at that price, like vintage tips were, plain copper. Thank you. These used to be at the 99 cent store. Not any more. And no RadioShacks in 100miles. ----> https://www.aliexpress.com/item/3-pcs...

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. Trying another way ----> [img]file:///home/externet/Desktop/P1010740.JPG[/i...

Re: Why is there no way to contact the Administrator?

Hey Len, ask telemarketers for their credit card number upfront.
When they ask why, tell you charge $100/hour to talk. Minimum charge 1 hour...
