--- A perfect day for flight practice ---
After record temperatures here in Colorado (37 deg C/99 deg F), the temperature plummeted overnight to 10 deg C (50 deg F). Low clouds and threat of thunderstorms kept most pilots at home, but it turned out to be a perfect day for flight training!
It was nice and cool, calm winds, and high enough clouds for flying locally. I was basically alone at Boulder Municipal Airport (BDU) and neighboring Longmont (LMO), and could practice landings and radio calls without anybody around. Perfect for a nervous student pilot.
The cold air made the little engine in this 50 year old airplane much happier. Yes, I am currently flying with gasoline, but I do see an electric (or perhaps biodiesel) airplane in my crystal ball. That is actually one of my main motivations for becoming a private pilot: I am convinced that the next big thing in EVs (electric vehicles) will be aviation, and I want to be ready. :-) ... See more
--- Upgrading our toys: Digital read-outs on the milling machine! ---
Bill has spent the last three evenings upgrading our little goofy milling machine with DROs (digital read-outs). The 3-axis DRO was less than $300 including shipping from eBay. That's a fraction of what such systems used to cost, so Bill is super-excited, to say the least. :-)
Although I still have to hand crank for the movement, digital read-outs makes it a million times easier to machine parts accurately. No counting turns or trying to see faded scales under dirt and metal chips. No wondering if I did four turns or five turns, or perhaps six, or was it three..? No stopping and re-measuring after you lost count. You just zero it wherever you want to, and look at the display.
With high-quality end mills (from eBay, of course!) and digital scales, you can do relatively high precision machining work on a cheap milling machine! The frugal Swede in me likes that. ;-) ... See more
--- Flashback Friday: 7 years since conquering Pike's Peak ---
I meant to post this two weeks ago, but I somehow missed the reminder I had set in my calendar. May 25th marked the 7 year mark of my homebuilt electric street bike "ElectroCat" being the first electric motorcycle to conquer Pike's Peak. Electric cars had conquered the 14110 ft (4300 m) tall mountain before, but this was the first time an electric motorcycle did it.
I was signed up for the legendary Pike's Peak Hill Climb race in June 2010, and I needed to get some data for energy consumption. The ElectroCat did successfully finish the race with rider veteran rider John Scollon. It was certainly not a winning time, but it was the very first electric motorcycle to ever finish the race. I should have ridden in the race, but was injured during practice and couldn't participate. Despite this very last minute rider change, we made a little bit of history.
Since then, electric motorcycles have had large successes in the Pike's Peak race, and it is only a matter of time before one takes the track record. As opposed to internal combustion engines that lose about half their engine power in the thin air at the high altitude, electric motors are unaffected. Electrics are simply perfectly suited to win this race! ;-)
I always like to say "You can be the first, or you can be the best. If you are the best, someone can beat you. If you are the first, no one can ever take that away from you." I like to continue doing things that are "firsts", I enjoy that much more than being the "best".
The 7 years since that first Pike's Peak ride just flew past, and I can't even imagine what the next 7 years will be like. But I am sure it will be yet another adventure, and hopefully it is will contain several new "firsts".

--- Fast girls! ---
I invited my mom to join me at the Signs Award in Munich, Germany, so we also checked out BMW Welt | BMW Museum and took the BMW C Evolution electric maxi scooter for a spin (OK, no spin, it was bolted to the ground, but we were imagining quietly swishing through the Alps... :-) ).
