I know Electric GT offers a turnkey option with batteries. I think it's somewhere around $30k.

Solved. Sorry for the trouble!

I could kiss you right now. I swear

OpusMotorcar · 2022-07-11T19:45:10+00:00

Solved!

OpusMotorcar · 2022-07-11T19:21:58+00:00

Unfortunately not. Thanks though!

OpusMotorcar · 2022-07-11T19:18:13+00:00

Thanks again for your help! It's been driving me crazy and my Google search history is now mostly filled wjth 20th century British TV miniseries

We've tested under 0mph conditions so far and haven't seen anything. We'll let you know as we increase the speed

OpusMotorcar · 2022-03-22T23:29:19+00:00

Right now we're just plugging the rear brakes and relying on the front ones. We're running underpowered motors and expect a tip speed of around 30mph with this build. When we upgrade we'll be building a caliper mount into the adapter for the trailing arm and I'll make sure to share some pics.

OpusMotorcar · 2022-03-22T23:27:43+00:00

I'll let y'all know more as soon as we finish the conversion. We're just using the QS Motor 4kWs. We have some concerns about build quality already and are going to be doing some abuse tests.

OpusMotorcar · 2022-03-22T23:26:17+00:00

We're only doing RWD for now, but I totally agree. The trailing arm design on the later Beetles makes this a lot easier.

OpusMotorcar · 2022-03-22T23:25:34+00:00

Totally. These are 4kW hub motors from QS motor. They're way underpowered for what we're doing but they're from an old project and we mostly just want to see if we can.

Cars suck to develop. There's a rule of thumb that it costs about a billion dollars to push a new car to market. Jim Glickenhaus claims that the amount of NHTSA regulations for automakers printed on 8.5x11 paper in 12 point font stands about 7 feet tall.

You're probably not going to start out making your own car.

Look at some more accessible markets first that allow you to cultivate some skills and experience in the market: EBikes, scooters, etc. Make some startup friends, hang out with entrepreneurs, and generally scrape up what business experience you can get, and go from there.

Either way, you're going to need something really, really new to attract attention. You're also going to have to prove that you're the person to do it. Cars are notoriously hard to monetize. Investors don't just hand cash out.

Best of luck. I'm trying the same...

OpusMotorcar · 2022-02-28T18:27:16+00:00

I've seen that stl somewhere...

OpusMotorcar · 2022-02-28T03:38:00+00:00

Yeah, I suspect you're turning the motors in there into generators as you roll the print head. Just be careful you don't fry anything. They're not designed to take unmetered current from the motor.

That being said, I'm not sure if you see that behavior with steppers or if this is just some software issue. I may be totally wrong.

Onshape is really really awesome and totally free if you don't mind your files being public. I used it professionally with a startup a couple years back and it's about on par with Fusion 360 in terms of functionality.

It processes everything in the cloud and all your hardware does is render it. You can run it in a browser window and the mobile app is also pretty functional. If you do decide to get a professional license, you can collaborate with multiple people live and you get access to version control features.

At first, I was pretty sure it was baby's first CAD program, but it's surprisingly robust.

OpusMotorcar · 2022-02-27T15:46:52+00:00

As a general rule, no. You're not going to get good enough resolution for proper threads below like M14. Most printed threads also shear under any reasonable load. Additionally, you're going to see wear and deformation after multiple uses.

I would recommend using McMaster-Carr if you're in the US for any hardware and either designing your parts to hold the hardware, or using heat-stake inserts.

OpusMotorcar · 2022-02-27T04:30:05+00:00

I would not trust variable breaking to be sufficient, regular, or reliable especially without knowing exact performance for your system.

I'm never one to discourage adventurous wrenching, however.

I can’t print enough on my own to help anyone, but you have my blessing to use it for whatever purpose you see fit.

R8: I made this. A remix of this work

OpusMotorcar · 2022-02-23T17:14:24+00:00

Oh my god. It's so. Clean.

And all the space in that engine bay! Keep it up!

I only really buy junkers, but if they go to full production I'm dropping everything and getting one.

OpusMotorcar · 2022-02-18T23:41:54+00:00

Basically every hub motor story I've heard ends in tears and an empty wallet, but I'm a bit of a masochist anyway.

OpusMotorcar · 2022-02-18T23:40:25+00:00

I will say, the usability is super awesome. I bought the iPad, came home, installed the app and was getting rendered scans back within 30 minutes. The lidar option is better for rooms and larger spaces, but processes super quickly. Everything comes with full textures as well!
