START HERE | FAQ for DIY Electric Skateboard builders

I’ve got a nunchuck, so I’m not as familiar with the specific pulsewidth numbers. I’d say test it plugged into BLDC-Tool without the motors plugged in and see what the graphs are doing.

I have it set so when my finger is off the throttle it is at 50%

Does it stop when you bench test it flip the board upside down pull the trigger let go does it brake? Keep the PWM display open/connected while you’re doing it if you can.

i have orangatang 70mm 80a 4president orange wheels and was wondering if a 12mm wheel pulley would work with them

What is kv? What is the best kv? I am conflicted from getting a 260kv motor, 190kv, or 149kv. I don’t know if the more kv is better or not. I am trying to get top speed around 21-25mph. Can I get any help pls?

I did not understand that thread at all. I just need a simple answer man. More or less kv for acceleration and speed?

Do more research and don´t jump on this too fast in the rush you are atm. It depends what you need and if it suits the rest of the system. Match the Kv with the suiting battery in the thread i posted. And do more research - use the searchbar. Have fun building

Can anyone tell me something about this Meepo Board ? I watched some videos and kind of like it.

I can tell you it’s cheap from China is basically a boosted clone but has relatively low rated wattage on the motors. Could probably do the claimed distance on flat (if the batteries are what they claim). Seeing as how you have the same name as the link seems like a spam post (also board smells like spam)

thanks for giving your first impression on My meepo board. Sorry that I have to get notice by this un decent way. I would like to send you a free sample of Meepo, You pay only when you think its strong and wonderful. How about that?

Appreciate the offer but not in the market for another board myself and no cash to spend on another board right now for testing. Sure you can get some more reputable member here to take you up on the offer though.

@kieraneboard i’ll do a YouTube review video if you want to send one to me for free…

Thank you for being interested. And can you promise that you pay for the board when it meets all the specs as claimed?

@kieraneboard the cost of my time to make and edit the video is worth more than the value of the board. i am happy to give an unbiased review and compare with other boards that folks in this community who are UK based and are willing to bring along for the video shoot. but i am not looking to buy a new board and to be honest i wouldn’t wish to pay for shipping. I am happy to return the board if you will pay for shipping both ways. I review a lot of audio and music production grear for magazines and the expensive stuff (£5k+) usually works this way, same with pre-production models. that said a lot of companies are happy to let me keep the equipment…

Good. Could you email me your address. [email protected]

That’s really not a good thing. Maybe you can try the ones here. I honestly haven’t heard about that Meepo board until now.

Meepo Beat them on price and quality price ratio.

I found a guitar hanger which works just perfect for electric Skateboard. https://cdn.shopify.com/s/files/1/2096/3333/products/[email protected]?v=1500000402

kWeld - “Next level” DIY battery spot welder

It originally started as a one-off, but through continuous support from https://endless-sphere.com/forums/viewtopic.php?f=14&t=89039 and http://www.eevblog.com/forum/projects/guesses-on-what-i-am-attempting-here/ , I am now able to offer my solution as a kit for purchase.

https://www.kicksurfer.de/index.php/product-category/kspot-welder-kit/ http://www.eevblog.com/forum/projects/guesses-on-what-i-am-attempting-here/?action=dlattach;attach=329176 http://www.eevblog.com/forum/projects/guesses-on-what-i-am-attempting-here/?action=dlattach;attach=332388

Here are some key specs of my system:

Hardware: Input voltage for welding: 12V – 30V Extremely rugged MOSFET-based power switch and mechanical current bus design Maximum switch current: 2000A Power switch internal resistance: 120µOhm Logic supplied directly from battery – no need for a separate auxiliary power supply

Software: Central weld control algorithm uses a Joule metering approach instead of a simple timer, eliminating the need for two-pulse firing and providing more consistent welds – the amount of energy that is deposited into the weld spot is always kept constant Ability to detect a failed weld, and acoustic feedback to the user Manual mode, triggered from external switch Automatic mode, accompanied with a warning sound and triggered with a 0.5sec delay, once the system detects that both electrodes are in steady contact with the weld material Audible feedback of weld process completion Numeric feedback from an executed weld, assisting the user to achieve best results: deposited energy amount, required pulse time for this energy, measured current flow, measured ohmic resistance of weld spot

It is not the cheapest solution on the market, but it has shown bullet proof stability. It is more than capable of welding 0.3mm nickel strips.

These videos show the system in action:

Cheers Frank
