Do not lose your cool at the slot car track - make this modification to your hand controller

Thank you James, 42 years of slot cars my self.

More bells and whistles on that controller than a Xmas tree 🙂. If youre really worried about overvoltage on the fan connect a 12V zener across the fan terminals after the dropping resistor. A 1W 5.6 or 6.8 ohm resistor should be OK coupled with a 1W zener.

Nice idea with the 12V Zener 👍🏻

Thank you for this series.

[@CleaveTech]

Glad you liked it. Thanks for watching 👍🏻

Always impressive what you can achieve in 12 seconds =) Very clean project, much better than many diy electronics tutorials found online. Thank you for sharing!

[@CleaveTech]

Thanks for watching. I wondered if anyone would comment on the 12 second thing 😉😂

@@CleaveTech I was going to on one of the previous vids, especially with otherwise trivial tasks taking from hours to eternities =D Made me smile. Thank you!

[@ViperMike-c2r]

Awesome video series. Can I purchase one of these controllers? Thanks.

[@ViperMike-c2r]

Hi James, great video just subscribed can I purchase a controller or do you have a schematic a list of all the parts that are needed so I could try to build one myself and a wiring diagram thanks

Good video as always and most helpful. Now I'm in the process of adding 30mm fans to my 13 year old 3rd eye controller. I will be using 2 or 3 fans with on off switch so a question I have is with fans running how much power do they take from the car or will I not notice much drop in power?

[@CleaveTech]

Hi Mark. The power loss that you might feel really depends on the track power supply, track wiring, sockets and controller wiring. Each fan should have a current rating and you can just add them up to find out how much current you will be drawing from the track power just to power your fans. You probably won’t feel any difference in power, even if you ran 5 fans, but there will be a small power loss to the car even if you can’t feel it 😉.

[@markhammond3800]

@@CleaveTech Thanks for the reply now I went with 3 fans and found the controller stays cooler and the car went quicker. Or could the car going quicker just be the brushes have nearly worn out on the motor.

[@CleaveTech]

@@markhammond3800 , haha, it could be a bit of both! A cooler Transistor means that there would be more consistency in performance and depending on how your controller is wired, there could be less power loss through the transistor at maximum throttle.

Do you have a part number or even better a link to buy the 16ohm 5% brown ,green, black ,gold, resistor the one I got from amazon was twice as big as the one your showing.

[@CleaveTech]

You probably need to check the wattage rating of the resistors. You may have ended up with a 0.5W or even a 1W resistor! A 0.25W or even smaller wattage resistor will be fine in this case.

[@nflpicks4920]

So this would be a nice summer project for me!! Can you provide a list of all parts etc to make my own controller?

[@CleaveTech]

Check out this link for controller building. The parts for a nice controller are all listed. You may have to source them from a more local supplier to you, but at least you will know what to ask for 👍🏻 www.chaskeelingscd.co.uk/building_your_own.htm

this was the most informative series I've watched in a long time. New to slot cars and i just built my first controller from scratch thanks to you. i found the website u linked awesome with ur explanation it was just too good to be true. send u some pics on insta

[@CleaveTech]

Thank you. So glad you loved the videos and found them useful to build your own controller. I will head on over to Insta and work out how to view the pics.
