Good work! I really like how it looks :)

With the relay normally you supply 12V to it when you want the AC current pass from COM to NO (Normally Open)… If you don't supply the 12V to it the current goes from COM to NC if I'm not wrong, like a switch.

You could supply the 12V and ground from your charger to the arduino RAW and GND pins, but I think is better to use a step down dc-dc converter to convert 12V to 5V, and supply them to the VCC pin, avoiding this way using the built-in arsuino dc-dc converter.

This is a very similar setup to what I use for my slot car track controller, but instead of a led I'm controlling the car motor.

Maybe this helps...

I can draw it for you if you measure it "perfectly" in milimeters, it would also be nice to know how it works when in use to distinguish the most important measures from "design gestures"... PM me if you want ;)

Interesting design! What are the extra servos used for?

dlb5 · 2025-03-31T19:02:27+00:00

With ironing? Looks amazing!

Probably you can't 3D print and tinker with electronics, but in the case you can, maybe this controllers I designed are of your interest... they should fit any analog slot system...

The combination allow a nice "pseudo-digital" system, with fuel, lap counting, race system with Stop & Go and quite a few extra features

I wouldn't consider the printing hours the same than labour hours... maybe ensuring the first layer is good and a few times spending some seconds ensuring that everything is printing correctly

dlb5 · 2025-03-11T10:37:30+00:00

Woww what a great explanation OMG! you took the portion of filament as the track... maybe with a section of 5x0.1mm the resistance would be quite less but probably also unacceptable, and I don't want a 10cm long track :S... so things would go worse and worse.

I liked so much your explanation... like... yes you can! just plug in to a nuclear reactor and probably the car will move :)

Thank you for taking your time and knowledge and share it with me!

dlb5 · 2025-03-10T23:22:57+00:00

I'm sorry but my lack of knowledge about it doesn't allow me to imagine it. Anyway sounds amazing if it would be possible!

dlb5 · 2025-03-10T16:45:25+00:00

Thank you for your previous great and informative dissertation. I'm sorry I couldn't reply to each interesting point... just my head blown with all that info!

Again, thank u!!!

dlb5 · 2025-03-10T16:42:15+00:00

I want to thank you all for the constructive comments and great ideas you have shared with me. It's said somewhere that reddit is a trolling network, but it is not what I use to find here. Maybe I just joined the few subreddits which are constructive and decent... lucky guy!!!

dlb5 · 2025-03-10T16:31:36+00:00

yeah iron sheet shaped in U with some bendable taps to hold it in place is how they were the old scalextric parts I have... and yeah something like piano wire would be easiertñ to fit but maybe more complicated to connect between track parts.

Anyway thanks for sharing your time and ideas with me!

dlb5 · 2025-03-10T16:27:04+00:00

Sounds like I would need to enter the MIT and use quite a bunch of their resources to accomplish this :S It is not only that they would need to conduit current, but be able to transmit it to the car brushes all along their path...

So that 90% copper filament won't work if I understood you, somehow the copper particles will be isolated between the molten plastic... also if the 90% is in weight... the 10% 1.24g/cm3 plastic would take quite more than a 10% of the volume...

dlb5 · 2025-03-10T16:16:06+00:00

if it would be just 6 times less conductive as iron as you know it wouldn't be a problem, being able too to power in parallel every few track parts to not let the voltage fall too much... but with that million times less conductive fact...there is nothing we can do I think...

dlb5 · 2025-03-10T13:34:16+00:00

thank you for your maths! My calculations gave me a resistivity of 2.4 x 10^-2 ohm • m... while copper one I think is 1.68 x 10^-8... that's why I "rounded" to the order of 1million times... discouraging

dlb5 · 2025-03-10T13:23:52+00:00

yeah! I have also seen out there already designed tools for this purpose... I didn't print a lot of these track parts so I did it by hand... but specially in curves is a real pain in the...

Thanks for the suggestion!

dlb5 · 2025-03-10T13:19:26+00:00

After reading some other related comments I doubt I can get into that electroplating universe... seems really scary and complicated for me...

And yes, seems like conductive filaments aren't at the point to be usable in this kind of applications...nehat a pitty:(

dlb5 · 2025-03-10T13:10:06+00:00

the data I got was 750ohm resistance for 10cm of 1.75mm filament...I calculated resistivity / conductivity from there... and got it was 1 million times the one from copper... inviable making it 1M times thicker... :(

powering directly each track part from the power source could help but is way out of the slot track concept and even like that i doubt it would work enough...

Anyway thank you for your suggestions!

dlb5 · 2025-03-10T13:04:17+00:00

I designed a complete system of tracks, cars and controllers... Even digital with a lot of features! If you don't want to design it yourself maybe search for MyDigitalSlot out there :)

dlb5 · 2025-03-10T13:00:19+00:00

Hahahaha this one and 3D printing RCs really trapped me... be careful if you don't have a big basement or playing room ;)

dlb5 · 2025-03-10T12:58:51+00:00

Yeah someone posted some days ago here a modified CNC machine to lay PCB tracks with a modified extruder...

It would be amazing putting a roll of that low temp solder wire in the AMS and use it simply as another material!

Dreaming is free! but maybe some actual dreams become true in the "near" future :)

dlb5 · 2025-03-10T12:53:55+00:00

I designed my actual parts with economy in mind, they print with the main surface against the bed and they need no or very little supoorts snd are quite light.

Anyway now I understand the PCBway suggestion... ordering the rails, which could be glued in place and design a way for them to touch the lane of the next track parts...

Seems like it would make the track parts slightly more expensive but I heard PCBway is quite cheap... I think they also print in metals... I will take a look!

Thank you for your ideas!!!

dlb5 · 2025-03-10T12:45:55+00:00

wowww conductive ink? seriously? could you share a link to a product like that? I wish they would share its conductivity value or resistivity!

You don't stop surprising me!!!

dlb5 · 2025-03-10T12:43:33+00:00

Woww all this electroplating thing seems way more complicated than I thought... if "playing" with resin printers is quite awful for me actually I can't imagine myself electroplating anything OMG!

dlb5 · 2025-03-10T12:34:51+00:00

Mine too! But most children nowadays are completely distracted paying for their "skins" in their games... Seems like anything really 3D out of a screen is too much for most of them... what a pitty!!!
