How About an Ultrasonic Pill Splitter?

When I was kid the first thing I ever saw labeled "ultrasonic" was a small cleaning device that held about one cup of water. It could clean jewelery, small instruments, etc. <p>As my interest in electronics increased, so did my fasination with ultrasonics. A local artist who carved incredible design...

A Thought Experiment - Thermoelectrics and Cars

I just had a idea. Wow, that was painful!<p>My dad, and everyone in the small town where I grew up drove large, full size sedans. This was during the 60's and 70's. Remember those old Buick station wagons. They were so long, wide, and heavy that the shocks could be blown out and you would hardly not...

Re: Flexible Thermoelectric Coolers Anyone?

When I described the thing I wanted to cool I really wasn't thinking about a can of soda. The object I'm trying to cool is part of a much larger device that costs many thousands of dollars.<p>Yeah, you guys are right. Thermoelectric coolers are big current hogs. I should have realized that construct...

Flexible Thermoelectric Coolers Anyone?

Does anyone sell a thermoelectric cooler (also called a Peltier module) that can be wrapped around something that is roughly the shape and size of a soup can. A flexible heat sink to go with the module would help a lot too.<p>I've seen a whole bunch of the flat, rigid kind. My instincts tell me that...

Re: Long Interval Clock and/or Timer Needed

WOW!<p>Thanks to all you guys for your replies.<p>Some of the ideas mentioned above crossed my fuzzy brain. Buying a cheap PDA or building a timing box of some sort were a couple of things I did contemplate.<p>Years ago, when I first got into breadboarding and building electronic gizmos my favorite ...

Long Interval Clock and/or Timer Needed

I've got a large fence around my backyard. The gate is always locked for security reasons. Before the fence was erected the person who came approximately once a month to read my power meter had no problems accessing the meter. Now, I have to leave notes all over the house reminding everyone to unloc...

Exceptional and Cheap ($30.00) Clock Radio

A white bread and mayonnaise sandwich may fill your stomach, but if given a choice you would certainly not eat such an unappetizing pile of goo!<p>For the most part clock radios are something like white bread and mayonnaise sandwiches. They wake you up to whatever station they're set to and that's a...

Re: Battery Backup for Clock Radio

Darn it, josmith!!<p>I saw that Timex Nature Sounds clock, pulled the box off the shelf and read it's features. I guess the manufacturer didn't bother to list the memory preset feature on the box. At least I don't remember seeing it listed. I looked at so many clock radios. Everything starts to blur...

Battery Backup for Clock Radio

Before surface mount components, hybrid modules, and super miniaturization it was easy to float a battery across a small gizmo like a clock radio to prevent memory lose in the event of a power failure.<p>A couple of 1N4001 diodes, a battery, and an optional resistor depending on whether the battery ...

Controlling Water Pump Speed

Years ago (when I had the patience of a saint) I experimented with every kind of SCR/Triac based control circuitry. I breadboarded heating element controllers, lamp dimmers, motor speed regulators, etc. It was almost like being addicted to a drug! Every new schematic I could find in a book or magazi...

Need Data Sheet For Discontinued RS Thermometer Module

I'm somewhat frustrated that have to post this request, since I once had several copies of this Radio Shack application data sheet.<p>Its for a thermometer module that sold for $19.99. When it was available through their many stores it was part #277-123. Later on it had to be special ordered. The mo...

Thank you Edd, Dean, and scottK.<p>I really appreciate your replies to my posting.<p>I made one mistake when I quoted the price of a new pack for this Milwaukee drill.

Drill Battery Pack Dies Suddenly!

Over the past few years I've purchased several professional grade battery powered tools. I drove seven or eight thousand screws with a Porter-Cable drill before the battery packs gave out.<p>I now have an 18 volt Milwaukee drill that's about 17 months old. Unlike the Porter-Cable unit, this Milwauke...
