In this video I will try to create off-road tires as well as an overpowered battery pack for my electric longboard. For the tires I will be using TPU filament and 3D printing to create them and for the battery pack I will be using LiFePo4 100Ah cells. Let's find out whether both ideas will work out. Let's get started!

  • This video made me feel a little better about my own project failures because forgetting a specific, important detail (like you did with regenerative breaking and the boost converter) is exactly the kind of mistake I would make

  • Why not have a 'brake button' which takes the voltage booster out of the circuit at the same time that it engages the regenerative braking?

  • There is another guy I watch make home made power walls. There are a lot of safety precautions with regards to these awesome batteries. Since they have more power density than tnt. Cardboard and kapton tape is a must. No sharp connections. Do not rely on the plastic on the cells but cardboard..

  • You are using a lot of batteries in your projects. Can you build a project that will test one of these batteries for a certain amount of time? For example, it will charge and discharge a cell for as long as you leave the device powered. So it starts by charging the cell, then when it gets to approx 4.2V it will stop charging and will start discharging up to approx 3V and then start charging again and so on and maybe measure either the number of times it charged the cell or the amount of energy used in the process. This would be very useful when you want to check the health of a cell over some time and/or a number of cycles. Imagine if you want to buy some cells from aliexpress or similar but you don't trust that the cells will last very long. You can buy one and have it in this device for a few months. A cell that is advertised for 2500mah will take less than 125 days to go through 500 cycles if the battery holds its capacity or less if it will decrease. After this, you could retest the capacity and see how much you have left. Best wishes!

  • Wait... so why couldn't you just set those batteries up as 2 parallel sets of 2 in series? You'd double the voltage and reduce the amperage to a slight safer level. Is it not enough amperage that way?

Can you make a video on how to design a circuit for pmdc and bldc motor and how to expand it power (say controller can handle 100 amps but after testing i need 150 or 200 ampss) if I need . Then how to do it. Specially I can't find a suitable controller around me so I want to make one . Please help.

  • I have been working on induction motors and generators for a long time now. And we do big boy stuff power goes upto 75HP for each wheel(thats 300horses and nearly 1200lbft torque). With experience I can tell, the initial bite to push you on the board the Volts will not help you at all, its the amps. If you record the power graph you will notice the current to kick you off is nearly 6 times off the current at higher rpm. So you need amps for the torque and volts for the speed. And they are inversely proportional in a constant power input(so are the torque and speed). Figure it out the next time.

  • Hi, Im Interested in building or buying an Electric Longboard myself, but have some questions about the legal side of it... Im from germany too, but write this in english as thats the language of your content and audience. So as dar as I know, something like this would be only legal on sidewalks or bike streets in germany if it can classify as a toy. Now to classify as a toy it must, apart from other regulations, for one thing drive within a certain speed limit. im not exactly sure how high it is but it is but it is pretty low... Now to classify as a roadworthy vehicle, simmilar to e scooters that were included in the last revision of the StVO, to drive on streets it has to have a handle bar or steering wheel. So am I right in my assumption, that electric longboards are technically illegal in germany, and driving them relies on the police not being interested in prosecuting you / ignoring you?
