Repair (Maybe) or Replace Mouse?

The microswitches inside a mouse are called "Snap" switches by Omron. They manufacture switches and relays by the truck load. The tiny bump on the switch that goes "Snap" is an appropriate name! A few years ago I purchased two Kensington 72121 corded mice. I liked the design immediately. The thumb b...

FTA Satellite TV

The latest issue of Nuts & Volts has a Q & A about Free to Air Satellite TV. I remember countless articles in various electronics hobby magazines about backyard satellite dishes. All these publications are now defunct, but it was a very popular subject twenty or more years ago. Several technically ...

Re: Small TV & External Speakers

This has nothing to do with my post, but I just had my upper wisdom teeth extracted. My eyes swelled shut. After that I kind of lost interest eating, sleeping, and small TVs! The swelling is almost gone after drowning my head with ice for 24 hours. Remember those incredibly cheap 13" (CRT style) B &...

Small TV & External Speakers

I just purchased an LG 22" TV (22LB4510). The sound quality improved after changing some of the settings in the audio menu. For a small LED TV the sound quality is acceptable. I plugged-in a pair of external speakers to the 3.5mm jack. No sound. The manual is written in plain english, but 90% of the...

2-Wire Power Strip?

I refuse to wear eyeglasses while I'm in bed watching TV. I've always had some kind of cart with a small TV next to my bed. It's tempting to mount a 30 or 40 inch flat TV on wall in my bedroom, but I'd be forced to keep my glasses on while I'm trying to fall asleep. I went into my shop and built an...

Re: I can't see these LEDs!

CeaSaR, I mentioned that there is a very small hole for the LED. I may be wrong, but I see some kind of "light tube" when I look through the lanyard slots. Could it be a small piece of fiber optic cable? Probably not. My first thought was to take the case apart and make that miniscule hole larger. T...

I can't see these LEDs!

I purchased a 32 and 64 gig USB thumb drive. I don't care about the brand, but I like flash drives that have an LED indicator at the back-end of the stick. I found a couple that got great reviews on Amazon and many other retail sites. They perform perfectly, but the LEDs can only be seen through two...

Re: Higher Capacity Sealed Lead-Acid Battery

Hey guys. Thanks for your replies. I don't post much on any technical forum. I always hear a little voice in my head saying, "why are you asking a question, when you already know the answer." The fact is, I purchased the newer version of my old, reliable Toro trimmers without much thought. I could t...

Higher Capacity Sealed Lead-Acid Battery

Many years ago Toro made a battery powered string trimmer (you know, weedwacker). It cost $50.00. I purchased two. The Toro engineers decided to completely ignore the appearance of this device. It was really ugly! The sealed lead-acid battery was large, which made the trimmer top heavy. I loved thes...

Re: Will This SMPS Run a 5½" Circular Saw?

You're absolutely correct, Steve G. All of these small battery powered saws stall out if you push them too hard. Startup or inrush current are big problems. Batteries are very forgiving because they're little chemical factories. As long as they don't run too hot, batteries quickly recover from high ...

Will This SMPS Run a 5½" Circular Saw?

It seems like I've always had a shop for wood, plastic, metal, etc. If you've been a lifelong tinkerer and builder I'm sure you have tools that failed for some reason. Total junk gets tossed but some tools are just stored away for years. You think, "someday I'll get that thing working again." I've g...

Re: Can a Cell Phone be Tested for Defects?

Since there is nothing we can do about it, I was afraid to mention digital telephony as a possible cause. Before the complete change over from analog to digital broadcasting, my TV signal from Comcast was very good. Now that everything is digital there is frequent (brief) signal loss that effects th...

Can a Cell Phone be Tested for Defects?

Virgin Mobile is my provider. They use Sprint's network. Signal strength is always strong (4 or 5 bars). I can call anywhere and person I'm speaking to hears every word I say. On my end there is a problem. The signal briefly cuts out about 50% of the time. I miss spoken words, so I'm constantly aski...

One Lever Moving Another with Precision

(I deleted the first two paragraphs, describing the device these levers are attached to. It really doesn't matter, but I'll include the info if anyone is interested.) Using 25 mm thick aluminum, I've machined a large bracket that clamps to a big lever. The darn thing fits like a second skin. Several...

Re: Printer Alignment Problems

OK Janitor Tzap. I should have checked on the availability of parts, before posting about this AIO. If you mention a malfunctioning printer to almost anyone, they'll tell you buy a new model. The exception are expensive laser office printers, that are usually serviced by a contractor. Reseting the p...
