Depends on your voltage too, though voltage is a controllable variable in the spreadsheet. My calculations were done at 48V. Calculating range & such is a function of total energy, and a 200ah-12V pack has 4 times less energy than a 200ah-48V pack.

Elegant little design, great work!

Looks great! How do you get the compost back out? I'd love to see if you could break down 3d printed PLA plastic, I bet it would work and trying it would get a lot of people interested in your project.

Is it possible to export Visuino code as regular arduino C++ code?

ooooh I like TPU for that because it would store well wrapped up. Ive a 5 yr old who would enjoy this if it could be all made usable for tiny inexperienced hands which is why I asked.

Looks great! Just a thought but maybe V2 could have a longer rip cord (for diagonal across a standard 200mm bed) and a finger hold for the spinner holder could be added in plane without supports. I

Actually, is this model open for me to make modifications?

Hi, I no longer sell the kits anymore or have inventory to offer.

No. I wont go out of my way to further contact you to help you...Not sure why you thought I would or should. This is the place for questions kid.

Niceeeee! Looks good all around, esp the output curve

Sorry everything I remember is embedded into this instructable. Ive built many projects since this but none are vehicle related.

Thanks! This device is driven exclusively with an arduino Nano with a CNC shield that I buy in bulk and include with the kits. An uno could be made to work but you would have to replicate the entire pinout exactly because the source code is not openly shared, so I do not recommend trying that way.

That's great! I don't want to misquote on the cost but I will say that the lowest price option will be the print it yourself kit of course. Im posting the kits soon, just shifting my shop over from prototyping to production.

Hi Tim, thanks! I got sucked into the rabbit hole that is your site and you have an impressive collection of projects yourself. Im going to check out that handwriting font video when I get more time. As for dealing with handles on the CylinDraw, you are right that an interference is possible. The current procedure to draw on the back face of a mug is to flip the cup upside down in the chuck and also flip the drawn image too. (This works well as long as the cup isnt tapered AND has a handle, but that combination seems uncommon.) Oven baking the ink on would be great, I need to figure out which ones are made for that purpose. There are a zillion types of markers out there!

Its been a long time since I thought about this stuff so I have to refer to what ive already written but I found another comment I left that says I got it from mcmaster carr and the details were: "finished-Bore Sprocket with Hardened Teeth for #50 Chain, 5/8" Pitch, 15 Teeth, 1" Bore". I did not cut the shaft, I just left any extra shaft length stick out.

Looks good glad you enjoyed!

Hi Grady, I moved everything over to CULTS3D here: https://cults3d.com/en/3d-model/gadget/bicycle-boosterpack-clamp-on-and-go-electric-vehicle

Thanks, I used solidworks.

FYI to anyone thinking about making this, Ive purchased those 61bit LED wheels from two different listings on banggood and in both cases they split up the rings into separate individual rings...! Making it way more work to wire & assemble this device than it seems.

HI Pablo, cool robot, I love the idea of use these in schools! I made a sumo robot too and I just checked and we happened to use most of the exact same hardware! So I thought Id let you know that you could probably use my code too so you can show your students how a totally different programming paradign will yoield different results. (My program is a state machine) https://www.instructables.com/SimpleSumo-Educational-Fighting-Robots/

This electric motor has full torque at 0 rpm so no gearbox necessary. Its electric motor- sprocket-chain-sprocket - wheel

If you feel you are unable to use a device safely then don't. In practice there is never any slack to wrap around limbs because the line is so short, the spring is strong, and it doesn't have a thumb button to lock the spool.

Solidworks

Thanks and done!

HI, yes I had to move on. This project was fun and I have left all the documentation out there for people to make use of and enjoy. But it was not the financially profitable experience I had hoped for, so I needed to continue developing new products.

Im sorry but I do not.

I have not done any simulations but Im sure the most likely mechanical failure mode is the fishing line breaking or the pin that holds the bearing shearing off. The force on the pin is almost entirely transverse shear and the pin is 8mm in diameter, but still I think its adequate for use on small game if your printer is good and the layers adhesivs is strong.

This is quite a hack! I would love to see this made from scratch tho, so it would be more replicable

Thanks! I have a maker license for Solidworks at home and i love it.

It refers to the settings you select when you prepare an object for FDM 3d printing. Perimeters are the exterrior layers of a print and they have an outsize effect on part strength relative to infill. I suggest using at least 3 perimeters when printing gears.

But THEN what would you make? Ive thought about things of that nature but CNC lathes are just not as useful as CNC mills.

This is a great design & well documented to boot! Congrats on the big win of your new laser cutter!!

Wow this looks great!!

Loks great and a well documented instructable, love it!

I dont think thats much different that what I used, but I wouldnt go smaller.

1. Agreed, mine is complicated but I didnt see how to reduce part count at the time.2. The 20v signal is just for keeping the relays triggered, it does not interact with the 9v signal. 3. >>>> Your updated design is very clever, I only see advantages! <<<<4. Nowadays there is another type of product available to address the core problem. I know a lot of 3D printers who use these self activated fire extinguishers designed for stovetops. https://amzn.to/2PisEMg

Thanks! I live by the KISS motto so much I probably should get a tattoo lol

Awesome thanks!
