Lars, that sounds a small bit harsh.. That said, my non-informed opinion is that we run into physical limits. Wires, FETs, etc. They may squeeze any extra few percent from tweaks to the design, and advanced tuning, but I think that would come at the expense of safety tolerances. To me the...

Old version I received one email, now I get dozens. I think something broke here.

I follow a few forum threads, and wish to reduce the number of emails. I used to get one email if there was a new post, now I get dozens for busy threads. How do I fix this?

Yes, but ethanol boils at about 79c, water at 100c. Cooler is better in this case. And we could reclaim the resultant vapor for later ingestion. :) Build a mobile still! 2 stones, one bird! Maybe feed the flammable ethanol into a turbo unit! I remember flying with my dad in his plane...

Everclear? ie 95% alcohol, drop that radiator, and just let it boil off. Or would that be stupid?

nice post, a bit too verbose, as I tend to do.. As for "the cloud". well sure if you want to put your data in a public place and then hope for the best security wise, then, yah, ok. mostly I go for local hosting, I got 4 providers doing FTTH for less than $10/month each. Not sure why I...

So what was it originally? Some kind of traction motor? It looks sturdy. Sumitomo is a huge conglomerate, they do most everything.. I did study engineering in Uni, but, wow, this is completely beyond any math or fabrication skills I ever dreamed of having. Statics, dynamics, inertia, ok...

Can you expand on that "Studied" bit? What were your thoughts, what, why, how? What measurements were taken, etc. Seriously, but man that is awesome! Bought three, then .. hardcore stuff. amazing dedication and drive. With an actual budget, so not just dreaming and "I wonder" stuff...

Can I get one made with the "Mad Max" style? extend them out a foot each way to provide space for fake pedaling motions, then weld on a bunch of jagged bits of metal, balanced of course. Do not want to not induce unwanted resonances.. Sadly, an under-served market space. Sigh. How much...

Meek shall inherit the earth, well SCREW that.. Never admit anything! Oh, yeah, it's cool.. indignant.. OF COURSE it is cool?!? everything we do is cool! Why would it NOT be cool? Full on, no shame for the win! Kids these days.. Get off my lawn, mumble..

Perhaps an undiscovered genius! It could happen..

I just love how you guys just crank out these cool parts, making it look SO EASY! Then a casual pic turns out to be super COOL, with ZERO effort. Unintentionally artistic? Or did he stage that shot and delete the first 212 tries?!?

Yah, I love the bete noire B/W look.. Artsy! :lol: With a hint of Russian Industrialism (a touch retro, nee (accent mark...) .. Dunno.. Maybe add a bit of a steam punk motif. sniff. And some robots with lasers! STOP GLARING AT ME.. OK, I will go away now!

But that is not counting the inevitable fakes! :twisted:
