Regarding ESD, I have Zero anomalies to date experienced on #24. I do dethrottle during surface transitions instinctively for safety (defensive rider) and I am generally running through similar rocky pavement / pebbly pavement sans the changing construct and materials found in a fully urban environment. Relatively low RF interference out here as well where I live. Transient protection diodes, etc seem like a solid way to go but depending on the current that must be dissipated, specs may need working out for repeated ESD attacks and bypass / return paths to be defined. My ohmeter measures to 20,000 ohms only so the wheels have at least that much isolation. Rubber is a generally good insulator- But Ohms law applies so if 20Kv is present you’ll prolly discover it travelling the easiest path back to the wires e.g. jumping through wheel core, bearings, etc. You prolly already characterized all this already so good luck hardening the setup. I would readily pony up for your next offering should you stay the course solving these sorts of issues as I think these are things fully worth solving and looking forward to your future creations. Have a great week, I’m back to work myself
I am also thinking there is possibility that spinning components such as motor core and wheel bearings, etc are generating transients the create back EMF cyclically (figure a switch opening and closing in a circuit), in pulsed fashion and at various frequencies, as well as lie in wait for easy route to discharge… I digress. Cheers.
We really don’t run into too many people on runs. When we do, maybe 1/5 are even interested in getting one. Throw the price point in , that’s 1/3
of them gone. Now that I can just say “look at MBS Agent” I’m a little hopeful that maybe we’ll see some strangers mountain boarding. Still. Hasn’t happened yet but this is very new.
Literally none of us who DIY and don’t own a company can “justify it.”. Not gonna stop me though.
Skaters of yore who rather not or cannot push and pump anymore, college kids who are already familiar with boarding around campus, folks in mid life crisis, gray haired folks in their 50s crisis, those who have mundane lives and looking to do something different and exciting, it can be a target rich environment. Maybe the industry as a whole can combine efforts to market properly and help define future culture. Food for thought…
way to make it poetic.
Marketing is hard especially in competitive environment with high price points. I think going to go-cart track events, mini moto, motocross and mountain bike/road bike events will get some units off your hands.
College kids are broke, grey haired will break and incel market is death by a thousand cuts.
Mid life crisis dudes/new dads/ aging skaters are it, but you gotta wait 5-10 years between each generational group. Hence the obvious lag in PEV market.
The tech is ahead of the market rn but it should swing back.
I work on mass transit buses and for years I wondered what exactly is the purpose of these Static Straps. All the hundreds of buses I’ve seen have them, older buses had two in the back, newer ones have one in front and one in back. They wear out, constantly replaced and are seen laying around the shop. Basically just a strip of a rubber material, bolted to a ground point under the bus, hang down and drag on the ground anytime the bus is in motion
At the shop we call them Static Straps but a quick search they are actually called Anti-Static Straps. Possibly an easy solution to discharge a built up charge?
MTA?
Absolutely fascinating.
Yea, I’d just connect hangers together and the deck with a grounding wire.
Though I think a bunch of new pre-built boards are getting into the DIY platform. It will be easier for people that buy those boards to upgrade them down the line instead of buying a brand new board.
Unfortunately this wouldn’t actually work in our case. We technically already have 4 anti-static straps - the rubber wheels.
Adding straps wouldn’t do anything, because the charge is being built up on surfaces that are not electrically conductive, and so those straps would be conducting to nothing.
I should put one on my car though so I don’t have to brace for the shock every time I touch the door!
Looking good!
Buses have huge tire contact patch but still have those straps. Just threw it out there. Luckily I’ve never had a had vesc fault that caused me to crash but I’d certainly drag a 10mm wide belt like strip if I was having vesc failures and it was a fix.Pretty wild this was even discovered as a possible cause for some vesc failures.
The big vehicle ones are more for static discharge when stopped for refueling since the vapors are more prominent. Most stations have discharge spots to touch before refueling. Those flaps get blown by the wind and dont make contact while driving. Most around here have gone to chains by now. Common on school busses.
The ones sold for smaller cars were like those magnetic balance bands and did nothing but hype
Thanks for the clarification. Sounds like they are required on certain vehicles. Totally makes sense. I never knew of discharge spots at stations
4th of July coming, who’s riding? I can’t wait, but its monsoon season here just started. So maybe in the mornings as late evenings is when the clouds sweat.
I think a stock class racing category is a good idea. Let’s more people experience racing in a safer and less intimidating way.
Making a stock class is useless when you have stuff like what happened to Evwan at esk8con happening, there are problems that cost nothing to fix and would make a much bigger impact than making everyone to buy a certain board.
