This is great!!!!!
@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.
Thanks. Useful to know!
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!
Beautiful work!!!. Note:Mach3 is usable with USB smoothstepper and other USB and Ehternet controllers.
DIY Metal Stamping
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!
Wiper Motor and Arduino Mega Servo
Excellent job and instructable!!!!!
Technical Origami with ORIPA, FreeForm Origami and SolidWorks - TfCD TU Delft
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 :-)
Cielo: Expanded Atmosphere
That looks great!!!!!
Cool!!!! Nicely Shown!
This looks great!!! I want to make a set!!!
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!

This is very CreepyCooolll !!!!!
This looks awesome!!!!
@DonL55 That's awesome info!! I will try to get an RCR123a and try it out. -Lee
This had me rolling. The brain transplant was over the top!!!!!! Awesome!!!!
Outstanding Design, Implementation, and Technique, I've wondered about those Kreg Jig tools. This looks perfect!
Awesome. This is much better than killing intelligent beings who are just trying to live and putting their heads on walls.
And Enchanting :-)
Amazing transformation. You are SuperWoman!!!!!!!!!!!!! Good to see you back!
@ LaserDave Agreed 100% They kinda suck the fun out of life.
Yes! I used to joke I had a calibrated tongue. For guitar effects: this was useful to tell if your battery was good enough to get through a gig.
I especially like the idea about re-using the clip!!!
Hmmm. If you know what you are doing it's not impossible.https://www.google.com/search?q=soldering+lipo&ie=utf-8&oe=utf-8
