Re: magnetic amplifier battery charger circuit

So, where does the 'magnetic amplifier' come in to all of this?
Certainly a simple regulator would be adequate

Re: Crazy Phone issues here..

Yes, here in the East Verizon is doing very little to maintain the copper system. Messengers are drooping, lashing is falling off and nests of abandoned cables are wound on poles. Good pairs are hard as hard to come by as good service. They ran my copper to a fiber concentrator a mile or so away a f...

Re: Powder coating power supply

Look around for a scrapped electronic air filter. Check the local HVAC guy's junk pile!
The power supply is usually a modular unit.

Re: Crazy Phone issues here..

Seen a central office lately?
No relays, clicking, buzzing only the sound of the air handlers.
It's all solid state and when Zeuss visits, it is unfathomable what he can make happen!
Upgrades are often downgrades.

Ahooga!

I was recently involved with a vintage Ahooga horn project for a friend, and it was was a good example of a plan almost not coming together. He wanted the horn to be self-contained in a carrying bag for concealment, and a wireless remote control to sound the horn. To start with, the horn is 6 VDC at...

Re: Technology Backfire?

Funny story.. I had a friend that had big power lines at the rear of his property. He gathered all the extension cords he could find, hooked them up and laid them down as a coil near the tower base. He couldn't believe that he only read about 1 volt so he had me check his readings. I also read about...

Re: jack Question

Thanks all, the jack has been found at https://www.tubesandmore.com/products/jack-stereo-14-pc-mount-fender-amps-88-99 The picture is out of proportion but the measurements in the specs are almost the same as the OEM jack. It seems that Fender also uses this jack on some amps, and the only differenc...

Re: CNC Router anyone?

Yes, I am aware of many CNC forums but I was hoping to attract someone that does work similar to what I am doing. Most of the time I am cutting flat work, like front panels and enclosures for products I produce. Square or rectangular cutouts used to be a royal pain and now it's just draw and cut. Ro...

jack Question

I have a Pyle portable amplifier in for service, with a couple of the front panerl 1/4" jacks broken. They are 1/4" TRS (Stereo) jacks, but they have two isolated switches. They have 7 terminals, Sw1, Sw2, T, R, S and it is board with a threaded barrel. The jack body measures 27mm long. 17.5 mm wide...

Re: Bud Metal Question!

Years ago I struggled to repair a water spot on a piece of furniture. The more I worked, the worse it got. I caller MinWax tech support and they helped make it disappear. First, don't sand just the area, make a bigger area the repair so it blends gradually. Next don't use fine sand paper first. It b...

CNC Router anyone?

Just a shout out to see if anyone in this dwindling forum is doing any CNC fabrication with a table top router. I've had mine up for about a year and have had pretty fair success cutting plastic and aluminum panels and enclosures. I would like to compare notes and discuss modifications I've done and...

Re: Technology Backfire?

I wound a 4 foot 1,000,000 turn coil of wire on the roof and hooked up a diode to charge the battery. It kinda works but the car turns left ok but its cranky on right ones. The GPS brings me back to where I started from in 23 hrs, 56 minutes and 4 seconds, the left turn signal is a bit faster than t...

Re: TV lacking remote control...

My shop set is a Vizio smart set and it would turn on from the remote but no other remote buttons worked, and only unplugging it turned it off. The remote was swapped with another proven remote with the same result. I found a power and main board set online for around $30. Swapped them out with the ...

Re: Bud Metal Question!

Most of the dings are on the back of the cabinet
where a fan cutout is milled. The front has a lot of machining but that is covered with a graphic overlay.so it is clean.
Since this is a product being sold I just want to cover the bare metal showing through.
