Me Like :) !!!!!

I like the textured look with the grill mat or fiberglass cloth. Cool !

That is crazy well done!!!

Beautifully designed and executed!!!!

Thats cool!! I have to make one for my cats to chase!!!

I was going to say Genius.... perfect execution too.!

Very cool. Lots of used for this!

Fantastic idea!!!, I just ordered the standoffs and magnets. Will work with the 2 of these I use:https://www.amazon.com/gp/product/B01MZG2D99/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

UberCool and funny!!!!

Hi, dllewellyn2, man that really acts like the 2 battery symptom. If you sparked a weld, it would( might) darken for a less than second and go clear. I wonder if they used a super cap or the second cell was not expected to expire so not accessible? Could you send me a pic at indigoredster@outlook.com, or if you are adventurous, maybe mail it to me if you want me to try an open it up( but no guarantees that I can fix it ) It sounds like an interesting puzzle.

Did you have 2 batteries in your helmet. Often the one the that drives the contrast of the LCD has almost no drain at all and will show 3V almost forever, but the other 2nd one that controls the sensing circuitry will be drained. Otherwise its either in the control circuit,pot,switch, IR sensors, and maybe the solar cel. I guess that's sorta obvious if it's not working :-)

Cool glad to help. I should sound better after if you crank it. Won't clip.

Awesome!!!! Good source of goo for many things too!!!

You really need to add some base resistance 16-100 ohms to keep from frying your audio source. Right now its driving directly into a diode junction short( what the BE junction of an npn looks like as as currently hooked up as load )

Wow this is uber cool!!!!!

Stop Fidgeting and Pay Attention!!!!!!!!!!!! :-)

I love this!!!!!!!!!!!!!!!!!!

Thanks Tom!! and again beautiful soldering and layout. Very compact!!!Do you use a stereo microscope?

Cat approval shows you are a good person! Great work on this! The wooden floor looks amazing too.

Kitteh Approved!!!! Awesome! I have a similar one I purchased for my office to grab a 5minute power nap sometimes!

Hi Tom, I did just that,and got the largest, but even zooming the pin numbers,refdeses,part numbers are badly pixelated. Can Eagle print to pdf? just add that as a file. Reason is: I want to make some :-)

Hi this is very well done and I like your layout. Add mention that it is an Eagle schematic and layout. The schematic is hard to read, please make/add a finer resolution one and a parts list.

This is an awesomely done instructable. The hookup and descriptions are dead on and easy to follow. I have an analog version of this that I've used since the mid 80's to help find shorted parts. It was indispensable when I did tour gear for George Thorogood and others back in the day. It located shorted output devices in large audio power amps. Without it, you had to unsolder multiple devices until you found the culprit. In hi power systems the heatsinking makes the old "inject controlled current and see what gets warm" method fails. At Hypercom a new proto build of a pos terminal design had a dead sort. Current limited injection alone didn't show any hot spots. It ended up being a solder splash under a decoupling cap. I will be building this! Thanks!

Awesome!!! Well described on building too!

What a great idea for those old panta-armed lamp things. Very Cool!!!

I really like the shape and form that results. You know, if you did this with mylar or shiny metallic strips, it would make an interesting scalable multi-angled degree retroflecter device. pdf saved.

Nice!!!! I like the detail and great distance tips!! Thanks!

What cool images this produces!!! Moody and almost mystical.

Maybe also try a heat gun and a paper towel to wick the wax off. Beeswax is an awesome metal tool protect-ant so that may be useful to keep on in some cases.

What a novel idea!!!!! Well Done!!

I would be honored :-) You do great work!

This is great. I remember flocked things. I think hte first one was a bobble-head puppy figure. This would be a good 3D printer object finish treatment!!!!

This looks really cool!!!!!

I had never heard of this. Cool!!

Very well done!!!!

This is Creepy-Bizzaro-SuperCool!!!!!! Had to make a word up for it :-)

Very novel idea! Awesome!!!!!

My high school physics teacher had a big metal pretzel can ( used as an overall vessel for the experiment) with a hole at the bottom edge thought which he ran a 1/2" tube about 4feet in length. The tube went into a small soup can filled with flour. He placed a small lit candle into larger can next to the can with flour. Then he place the lid on the overall vessel can.When he blew into the tube, it would then blow the flour into a dust cloud inside the can which the candle would ignite and POOOOFF, the top of the vessel would blow off and hit the ceiling. cool experiment to get kids attention!!!! Kudos out to Teacher Carl Boyd of Delaware 1979!!!!

Ignore the trolls they are innovation killers.

Awesome that you did the entire drone and radios!!!

Like this :-)

Excellent !!! This could also be a great 123456 hand clip set

I like the Amber color. It antiques it a bit.

Agreed. The 1/8" x 12"x12" ones I bought have at least 3 layers from what I see.

A lot of general purpose laser cutters handle 1/8" plywood well. That what it looks like to me. Amazon has tons of venders for this.

Excellent things!!!! I will be making some of these!!!

2nded Beautiful!!!!!

This is great!!!!!

Nice!!!!!!!!!!!

@Nobster146 It's apples and oranges: An IGBT is much like a mosfet front-end and a BJT back-end combined together. New devices of both types have improved so much that either can do the job if selected properly. You want to look at voltage, amperage and especially the SOA characteristics of the devices (datasheet) and determine the needs of the application. IGBTs used to be best for under <20khz operation, but newer ones have pushed that limitation up.

Great Job!!!!!!!!!!!!!!!!!!

Very cool!!!!

Thanks. Useful to know!

Soap?

I've not seen solid glycerin. Where do you get it?

Awesome! I have tons of chucks laying around from surplus. This will be very helpful!

Awesome!!!!!

Beautiful work!!!. Note:Mach3 is usable with USB smoothstepper and other USB and Ehternet controllers.

Exceedingly cool !!!

I will work some up.

Please never take my comments as trolling. I try to only comment on stuff I really like. I was a HW/SW designer for a large point of sale company and we had to generate true random seeds for certain aspects of the terminals. One method used did checksums over volatile memory or registers prior to being initialized. Some ideas used dynamic memory that was temporarily refreshed then tested during charge fade. I just wanted to help to improve seeding for lottery chaos happiness.

I like this!!! I would also add some mixture of the seed being derived from XORing accelerometer shakes deltaT's ( more then one axis), temp, humidity, and the analog read A0: is that just an A/D read of the open pin? Does it change radically from successive reads? Very cool and well done!

Nice work!!!!

Excellent job and instructable!!!!!

Interested :-)

Very Cool. Thanks for the instructable, program links, and info. This could be used for machine tool way covers/bellows design.

This older brand of helmet had non-replaceable batteries. No access to them. So using external cells makes it easy to replace as needed. Newer helmets are trending to make the batteries replaceable.

Excellent Excellent Excellent Job!!!! This will be useful !

This is cool. I await the video!

Beautifully done! Is there anything you can't do? You have super powers :-)

A-Mazing!!!!

Blown Away!!!

That looks great!!!!!

Cool!!!! Nicely Shown!

This looks great!!! I want to make a set!!!

Looks amazing!

Striking metallic coolness. This reminds me of a vintage art set technique, but I cant put my finger on it....

Nice single layer layout flow!

Excellant idea!!!!!

This is going to come in handy!!!!!
