Does anyone know what is used in industry to "lock down" trim pots after they are adjusted. I know that nail polish can work but is there an actual product used professionally?

Thanks!!

In many ways printing has become cheaper. I have a Samsung laser that I purchased for under $100. I bought a bottle of powder toner for about $19 online and it can refill my toner cartridge 4 or more times. There is a plug on the end of the cartridge that pops off and you carefully add toner with a ...

I currently use two webcams. one a cheaper ($100.00) camera from Linksys that is stationary and the other a tilt-panning camera from D-link,the DCS-5200 ($300.00). Both are mounted in a window on the second story of my garage. Both have worked well in all temperature extremes here in the summer and ...

I saw these at Radio Shack also. They sell three different sets from about $38 up to about $99 or so. Pretty cute electronics kits that you can use to build a whole variety of circuits. They all "snap" together with metal snaps. Wish this had been around when I was a little kid. Great idea...

"HORN noise detector"!!!!!! What a difference an "R" makes!!!!

I have gotten the March issue already!!!

I elected to get my Nuts & Volts via PDF instead of hard copy and burn them to a data DVD. So far I have close to three years on one DVD...handy for at work. Maybe even save a tree!!!

I believe there is a technology, quite old now but appears on many hand held tape recorders called VSC or something like that for Variable Speech Compression. An IC was invented by a company of the same acronym and allowed a person to "speed listen" to voice recordings assuming the IC was ...

Bob,

I will check the neutrals in the service box just in case any are not snug. Good idea. I hope to look at the fan this weekend and see just what is causing it to remain in high-speed mode all the time too. All good suggestions... and thanks to all!!!

haklesup, That's what I think and hope for. I will look at the connections inside the new fan and try to determine what may have vibrated loose, etc. in the first 24 hours of use. As I look at the other items I should see right away the mode of failure (the dimmers, that is). I think the former owne...

I will have to remember not to tie my dog to my defective ceiling fan!

Interesting. Here is something that I did not mention with the newer ceiling fan. Oh, it's not Hampton Bay but a similar cheap one. The second night after installing it, it was running on low speed. In the middle of the night I noticed it was running on high speed. At that point, pulling the speed c...

Hmmm. I investigated the typical Fan speed chain switch and it looks like they indeed just switch in/out windings on the fan motor. I just don't get how a bad ground in this type of switch could cause the fan to run at high speed no matter what windings the chain switch switched in. But I do suspect...

Just throwing this question out there because I know you guys will have a quick answer. Anyone know how the typical "chain pull" speed control works on low price ceiling fans? This is the typical 3-speed control that goes from high-medium-low-off with each pull of the chain. I ask because ...

The best motion sensors (IMHO) are "passive IR" or PIR. You really cannot build one from scratch as cheaply as you can buy one. Many stores like Walgreens, Walmart, etc. sell little battery operated PIR devices that are either battery or AC operated and light a bright LED or incandescent b...

Mr. Al, If you are working with students then you should know this already: If an approach to solving a problem is so limiting and constraining it is probably not the right, or even preferred approach. Whom are you protecting with limiting the complexity to a point of compromise? I believe in keepin...
