Why is this trending?

@ivorjawa I want to know if he survived. Keeps popping up here and there from time to time from different people, and each time I think: "I really hope that guy's still alive."

@@pantherapardus1398 you’ve got the wrong CWMG. I’m referring to a guy in my apartment complex in Alameda, CA about 8 years ago. One of those big luxury cruising bikes, always playing Careless Whisper loudly as he left the garage.

@ivorjawa Oh I see.

searching, and finding nothing...😕

Mostly like a helicopter. Math is all pretty much the same, except the disk isn’t fixed over a center. I’ve got standard helicopter controls with some switches to govern whether the platform moves as a flat plane, or in spherical or cup-shaped motion.

I looked, I can’t find it. I don’t even remember if it was an HDL I used or a state machine built with schematic capture.

@@ivorjawa awwww man..thank you so much for the answer anyway

@@anisakaric5130 Here’s someone doing the same thing and explaining it better than my code would. www.instructables.com/How-to-Control-a-Stepper-Motor-With-an-FPGA/

Thank you so much for the help,i truly mean it@@ivorjawa

Not building a full helicopter (with this model), just learning how to model them.

Just wanted to learn how rotorheads work, mathematically. Full explanation here: github.com/ivorjawa/rotorhead/blob/master/RotorHead.ipynb

It’s a coil. It doesn’t matter.

I mean, I’m literally using a Lego train controller here to go from +9v to -9v.

@@ivorjawa Either of the 2 pins of the voice coil are + and -?. I have a PC source for the voltage. 5v or 12v?

@@omnia_tempus_habent yeah, it’s just an electromagnet. Positive voltage it goes one way, negative goes the other. 12v should be fine. Like motors, the voltage is really only limited by the resistance of the wire and dielectric breakdown of the insulation.

It can but not with the line follower program. With a controller I’ve got it set up sort of like a helicopter.

5.8 GHz video isn’t great

It’ll be a while before the code is clean enough for public consumption.

thank you @@ivorjawa

@@antek9702 I’ll put something up on GitHub fairly soon I hope.

Pretty sure it was to drive an electric frying pan I was using as a reflow plate. Had a thermocouple glued to it with RTV silicone. Fun project.

Sparkfun. Might be difficult to get ahold of right now. www.sparkfun.com/products/15536

I’m pretty sure I got those wheels in the original 1998 Mindstorms set.

The wheel part number is 2903. www.bricklink.com/v2/catalog/catalogitem.page?P=2903&idColor=1#T=S&C=1&O={"color":1,"iconly":0}

@@ivorjawa thank you mate. Cool part

I ask about other part, the wight one for the steering. Sory if my english is not that perfect 🤦. I guess its come together with that set.

@@yuvallegomotorized oh, that’s from the 1988 8865 Test Car set. www.bricklink.com/v2/catalog/catalogitem.page?P=2737&idColor=1#T=S&C=1&O={"color":1,"iconly":0}

There is an independent motor for each wheel. The differential is the microcontroller.

@@ivorjawa Can the microcontroller handle the different speed meanwhile turning?

@@Pales27 look up torque vectoring.

One of the technic turntables

Was it ever assembled tho?

Mindstorms is lego.

@@ivorjawa well, I never know about it, thank ya

Everything interesting about this build can be inferred from looking at that joint hard enough. I don’t like the way this one turned out; I’ll post something better once I get the steering worked out, and I’ll post instructions for that.
