a good source for magnets like that is the magnetron tube from a microwave oven. the advantage is you do not have to overcome the glue that is used with speaker magnets and they are also very strong and a simple wire cutter is all you need to get them out.uncle frogy
how much current does the draw?uncle frogy
what metal is the wire screen made of?uncle frogy
LEDs and Lighting Class
the look of the finished project in photos does not really indicate size very well.it looks bigger than it must be as an index card box is probably not 18" high by 18" wide by 8" deep as an amp good job!uncle frogy
well there is the LM386 of course which is an OP ampuncle frogy
I had need of just such a switch inline with a big ole 1/2 inch drill motor I was using to mix some stucco I had the drill lock on and the dam thing slipped from my hand continued spinning and wound up the power cord and broke it. all I could do was stand and watch.never thought of one of these before thanks for posting it. I will add one to my kit in the near future.I did make something a little bit similar for working on electronic equipment during trouble shooting. I got tired of having to keep plugging and unplugging the power cord so a put a single through double throw switch on a power chord to switch hot and neutral I left the ground pass through.always like good ideas!uncle frogy
let me try that again a single throw double pole switch to switch the hot and neutral ground is a pass throughsorry uncle frogy
an OK improvised junkyard amp suitable for the lab or prototype testing but not "road worthy".I have a fondness for this kind of "post apocalyptic design"uncle frogy
I was thinking do I have any nice square nuts have I seen any at the big box hardware store?then I thought T nuts would work and I have a bunch of them in different sizes.. This is just what I need to hold small work pieces at the drill press because it is no fun when the bit grabs just as it punches through specially in metal.uncle frogy
great idea. I have always disliked the "decorative" only use of expensive and still useful vacuum tubes. but these could be made out of dead ones rendering them no longer useless though still visually interesting. Your choice is opened up to tubes that do not have any common use today, look in any long dead TV's great thinking!uncle frogy
your project gives me too many ideas I was content with making do with my shop which has grown as the jobs range has increased. Just what I needed another project! I think I can adopt some of this one to help consolidate and organize the space in my too small of a space for the all the work I end up doing.The cabinets are a great idea because it is dust control that is a major problem in an active shop and the cabinets keep stuff, the growing hardware and tool collection, in enclosed spaces away from the "f''n" dustuncle frogy
I have a very similar drill I have done a little work on. it is too fast for most of the things I need a drill for but I did press into service as the power for a drill bit sharpener that likes the higher RPMs. I all so have a 1/2" drill of the same vintage that does not spin very fast but it sure has the torque for big auger bits over 3/4" and up and does a swell job of mixing 5gal. buckets of mortar and plaster does not get hot or bog down both could use a little polish though then I might be afraid to use them
That looks like what you said it was an environmentally safe method of trapping wasps and rather simple to build.I do not like being stung by wasps much either and have not been stung very often because I do not hassle them. All wasps are carnivorous I had the most numerous nests when I had dogs and the unavoidable flies which the wasps were eating. I like flies much less than I like those things that eat them how ever and preferred to just make the wasps not build there nests right in any paths I would have to take on a regular basis. I do not have any dogs at present and now seldom see any wasps in my yard and no nests I can find.uncle frogy
that is a pretty ingenious set up for extracting lye from wood ashes.

was there any problems with the rotation like wobble or vibration? A balanced sphere or wheel rotates easily but that "loop" besides the air resistance is a different thing.uncle frogy
I never thought of the steel wool screw trick that is now store for future referenceyou must have a very controlled touch to use steel wool on glass like that many would probably ruin it I was told that when the windscreens of small planes are cleaned it is ad vised that they only go up and down so any streaks and small scratches only go in the same direction might be because they are plastic but any way.I have used steel wool to patch rat and mouse holes to good results. I used a little courser grade and in-bedded it in the plaster they have no problem chewing plaster but they can not chew steel otherwise they would be eating through caned foods and peanut butter jar lids.uncle frogy
that is a nice one time use hammer cheap and quick to make but not built for strength or long use. It reminds me of the soft blow hammers plumbers used when working on cast iron drain pipe. they were a piece of black pipe for a handle and the working end was a beer can filled with lead. they would put a fitting on the pipe push it into a can and fill the whole thing with molten lead. lasted long enough and could be reformed when it became too deformed in use and it did not break the cast iron pipe.uncle frogy
