Yes. glad to... but give me a short while - a day or so - to recalculate the details and write it up. Jim H Received from Dave at 3/22/2019 02:25 PM UTC:

Thanks Lee, ? I have to get some tips yet. But that may work.

If you scroll down that link and see the pictures of an opened wand, there is an LC at the tip connections. Not sure the values. [email protected]> wrote:

I just verified I could test mine with paperclip as the outer coax jumper, and a arduino type jumper with the plastic rounded using an exacto blade to fit in the center contact, that I was able to

Pretty much need a handle and tip to test. However, you might be able to wire just a tip with a diy socket of hobby brass or an Arduino type wire jumper and outer clips. It's at RF frequencies so not

Good find and useful info. Thanls

I like that idea. I actually looked for that container at Walmart once and will have to look again to see if they still sell it. Until I build my plexiglass tank (lot's of irons in lot's of fires

Jeffrey, ? Thanks for the idea on the tank. I am going to build one but until it gets done I will likely etch in a plastic container.

Jim, ? Could you explain more on how to make the mix with the copper wire? I like the idea of less corrosive fumes. Thanks, Dave

The Metcal wand as I understand it, is just a length of flexible coaxial cable. Has anyone tried to home brew one? I have a stash of EBay tips that don't fit my MX500. Maybe thats a way to use

Both lights, red and green? Normally, green is power, and if there is a red light, then that indicates that the tip in the wand is disconnected, defective, missing, etc.... That is about all you can

@Harvey, ? I picked up an older PS2E-01 from ebay without a soldering pencil and it was listed as "tested-good".? I got the unit and both lights appear to be on when powered up. Is that all it

<https://www.buerkle.de/files_pdf/wissenswertes/chemical_resistance_en.pdf> is a rather complete chart of chemical resistance of various plastics. Legend and description of the chart's resistance

I've used the same one for the CuCl/ H2O2 and HCL mix. The seal around the top may not hold up, but the tank will. Harvey

Polypropylene is pretty unreactive. I doubt any commonly used pcb etchant will affect it.

Another possibility for the tank is to use a Storage Dispenser from Walmart. The dispenser is the kind used for storing and dispensing cereal or other grains. I've been using one obtained from

If you're adding H2O2 to the solution, you don't need bubbles to regenerate since the oxygen from the H2O2 will do the regeneration. Personally I'd make a solution of copper wire in HCl and H2O2 and

Jeffrey,You need bubbles if you use HCl plus H2O2, to regenerate the solution. The benefit of bubbles is double. They regenerate the solution and agitate thy he bath at the same time. Just a

I would suggest that for an easy low cost etching tank, go to a thrift store and purchase a suitable sized crock pot .? Make sure it is a ceramic one .? They are not affected by Ferric Chloride ,
