oldschool@tubes.com: Jul 01 12:42AM -0400 Most of the new scroll saws have variable speed. I have an old Delta from somewhere around the 1970s. The saw works fine, and is built much better than the new ones which have a lot of plastic parts. But it has one drawback, no variable speed control.   I've seen schematics for motor speed controllers, but I already have too many projects to do. Is there any reason I can not use a regular light dimmer to control the speed? I would use a dimmer rated at 600W or greater. (The saw runs on my 300W inverter in my car, so it's not a huge power user).   I also have some old electric drills that have bad motors or stripped gears, which have variable speed switches. I suppose I could modify one of them for this use too, but since I need two hands for cutting the wood, I cant be holding a trigger switch. That's why a light dimmer seems most useful. I can just dial the speed I want and dont need to touch the dimmer unless I want to change the speed.   Plus a dimmer could just be mounted in an electrical box, with a receptacle next to it, and I can just plug the saw into that box.   But I am asking about this because I am a little concerned that the dimmer could be hard on the motor, since these dimmers are made for lighting, not motors......

"pfjw@aol.com" <pfjw@aol.com>: Jul 01 04:02AM -0700 A resistance dimmer (gets hot) might work. Some triac dimmers might work. Look for a variable fan speed control. That would be the ticket. Noting all the while that the scroll-saw motor is not designed for variable speed and will likely heat up in short order. Many motors 'attempt' to draw as much current as they need to operate - and why it is that motor-type items hate brownouts.   Peter Wieck Melrose Park, PA

If ran too slow that fan will not pull in enough air and the motor will overheat.   Company I worked for burnt up 2 motors of about 100 HP running it on an inverter to slow it down before I looked into it. Put an external powered fan on the motor and all was well.

oldschool@tubes.com: Jul 01 04:04AM -0400 I needed to replace a 1/8" stereo plug on a cord. I found on ebay a pack of three 1/8" stereo plugs from China, for about $2. I dont normally order from China, but for the price and since I was in no hurry for them, I bought them.   That was a mistake. They are NOT stereo, they are THREE CHANNEL. The tip of the plug has THREE contacts, (plus the grounded base). What the heck are they for? I have never seen any 3 prong 1/8" jacks on anything.   Yea, I could just ground the uppermost terminal so it acts as a stereo plug, but it gets worse. Under the shell, I found a solder on ground contact. But none of the three conductors have any contacts attached to them. There are just three pieces of "rod" sticking out the back, with the insulation in between. I would have to wrap the wires around them, and solder them and by the time I manage to do all that in that tiny space, I'd probably melt the insulation between the sections and unless they wires were hair thin, they would short against the ground terminal.   For the small price, I am not gonna make a big deal out of it. I'll just have to order some properly made plugs from an American manufacturer, and use these worthless plugs for a conversation piece.

Don't tell me you've swallowed the Trump Kool-Aide? I doubt that 3.5mm jack plugs were ever manufactured in the US. If they were, it was likely before the early 1960s. If want REAL quality, then look at Neutrik. Best 3.5mm jack plugs in the business. You guys really have to get over this 'inch' bullshit. Everyone on the planet, save a tiny 5% of the planetary population has embraced the Metric system. Hell, engineers and scientists in the US use it.       -- Trevor Wilson www.rageaudio.com.au

I have never seen any 3 prong 1/8" jacks on anything.   You seem to have bought TRRS rather than TRS plugs, mobile phones often use them for stereo headsets with mic (and sometimes answer/end call buttons, or FF/REW buttons)

Personally, I do not use > them. If I need dimming, I use an LED.   Some LED bulbs are switch mode, usually flyback AFAICT. They are pretty much the same as CFLs on a triac dimmer.   Most cheaper LED bulbs are wattless-dropper - I haven't bothered trying any on a dimmer.   I've seen data sheets for PFC front end CFL and LED driver chips - but no products on the shelves so far.

We still have some few legacy LED lamps in place (stuff that came-with other stuff), but we do not intend to dim those.   NOTE: some cheap LED lamps are very noisy in the RF range. VERY noisy, approaching that of an unshielded ignition transformer (oil burner).   Peter Wieck Melrose Park, PA

"pfjw@aol.com" <pfjw@aol.com>: Jun 30 01:22PM -0700 When dealing with closely held beliefs, revealed religion and pronouncements from burning bushes, only war will determine what is 'truth' - and only insofar as the winner writes the history books.   Keep in mind the 'simple truth' of Evolution:   In the United States:   19% believe in Evolution. 34% believe in pure creationism. 25% believe in 'directed evolution'. The rest have no opinion.   And the US is by no means any different than the rest of the world in its beliefs.   So, something as esoteric as lamp filaments... you get the picture.   Peter Wieck Melrose Park, PA

The voltage steps cause current pulses that increase resistor P_diss massively. They dim perfectly on variacs - but probably no-one uses variac dimmers now.   I suppose in principle a mosfet dimmer could switch off & on at the same voltage each side of the peak, and thus work ok with CR PSU LEDs, but I've not heard of such dimmers - not been looking for any dimmers for years though.     NT
