Hunka Hunka Burning Love

Hey @esaj I ran across this interesting MESR-100 ESR capacitor tester, and I thought maybe you might find it handy. Component tester Kinda neat mini-oscilloscope (probably not that useful)

Wringing gauge/gage blocks. Interesting phenomenon. Science!

Forever is such a indeterminate period of time, but it does seem like forever already. I haven’t sold any of my EUC stuff, but I’ll probably ride again someday. Just gotta find beefy elbow pads! I know it’s weird from riding at every single opportunity to no riding at all, but the financial responsibilities seem to be preventing me from taking risks at the moment. Oh well someday someday! I did manage to replace a couple of tricky engine mounts on my car this afternoon so that was fun. And grimey! I had to Scotch Brite pad myself clean in the shower since the grease was not coming off! Happy riding to everyone!

But the thing is it took you 58 seconds to figure that out (more for me until I watched it a couple of times)! Seriously though they did a crazy good job with the CGI it's getting to the point where if someone took the extra time to make it perfect you would think it's totally real. It's getting there. Want the heebies? Watch this video.

It's not common at all for EUCs to quit working at 20 mph, but rarely for whatever reason they can (eg. due to overspeeding, bad battery, unseen bump in a sidewalk while running high tire pressure, etc) so you have to be able to deal with any possible consequences. We all hope that any falls are manageable, but things can go south really quickly so unless you're a Ninja you really need to be padded up and be prepared as much as possible. I've got a job that is physically demanding with tight tolerances so manual dexterity is critical. My shoulder is 99.99995% better, but there still is a tiny bit of not happy tissue in there that twinges in certain positions. A big problem is that over time riding feels so safe that you forget the possible hazards and end up going faster and faster or taking that bump a little quicker or just miss seeing that pothole or road ridge up ahead... Still it's crazy fun zipping around on one wheel. I miss it so much.

Way back, I remember someone who desoldered his MOSFETs to move them to a daughter board. I think he basically used a wire cable to connect it to the mainboard. I wonder whether moving to an easily replaceable MOSFET board might be a consideration for the future. That way it could be designed like a mini-CPU board with a heatsink on top and a fan as well. It could be located in a better cooling area so air flows over the heat sink fins. Or maybe even a ceramic heat sink could be used for better cooling. There didn't seem to be any timing issues, but I think that was one concern that was raised. It sure would be easier and cheaper to replace just the MOSFETs on a mini-board if those are the only things blowing.

I was wondering whether that residue could have been the silicone waterproofing paste they tend to slather on?

Hey hey I was just taking a break from the whole EUC scene since I haven't gotten my riding itch back. The more I read the forums and watch videos the more I miss it so I've been doing other things pretty much. Looks like everyone is still having lots of fun riding which is great! I still haven't found what I'm looking for in terms of arm/shoulder protection, but I was eyeing some CCM heavy duty hockey elbow pads with thicker cushioning. My theory is that if I can find something to fall on with my arms that helps decelerate the fall, that should help reduce strain on the shoulders allowing me to ride again. But maybe it's best that I just watch from the peanut gallery for some time though. It's good to see everyone continuing along with EUC riding!

Nice new wheel! I didn't quite make it through reading all 19 pages of this thread , but sorry to hear about the disappointing MOSFET failure on the steep hill climb. I think it's important to remember that these electronic gizmos do have their limits. That hill test is pretty much an extreme case which most wheels aren't purposely designed for. I wonder if we did a survey, how many people would say that they absolutely need an EUC to be able to climb such a steep hill for a prolonged period of time? How many of us have actually done a similar hill climb? Probably not a huge number of people. It's almost like expecting all cars to be able to run the 24 Le Mans road race. Unless the car is purposely engineered to survive something as grueling as that, most likely will fail. These consumer grade EUCs are likely targeted at the average person's needs. They have come a long way in accommodating heavier western riders with larger feet, but they really haven't made huge leaps. It is getting there slowly but surely. Do we all wish EUCs could climb the steepest hills and never fail? Definitely! But I think if we are honest with ourselves and understand the reality of it all, the Nikola will perform just fine for the majority of riders out there within a reasonable range of riding conditions. It's too bad it didn't fail gracefully though (ie. tiltback to allow rider to dismount and wheel to cool) as that would maybe allow people to forgive it's steep hill climbing failure.

I still miss it. I had a dream a while back about riding my wheel and the good times I had. I just can’t afford to have a more serious injury considering my profession. Arm is 99.9% better after 9 months, but it still hurts to sleep on my left side. Annoying! You guys be careful out there!

I wish I could go to Denmark! Sadly no I’ve never been there. Although I’ve lost some of that lovin’ feeling for riding, I still have an itch to get back on. The slight twinging pain every now and then in my left shoulder reminds me not to though. Until I get some better elbow padding at least!

It’s still alive. Pooping like crazy and wanting to bite everything in sight. I hear some bunnies aren’t as destructive. I guess I lucked out and got one of the odd balls. It’s soft and fluffy and cute, but man it’s got attitude sometimes. If it doesn’t get its snacks it shreds up its cage paper and flips his waterbowl over like a disgruntled prisoner. Not a good pet!
