Picture of LED longboard! LED skateboard version 4!
I know I have said I was done with led skateboards because I want to move on but I had to improve my longboard before I put everything to rest! I use my LED longboard more than my other LED skateboards simply because I am less likely to do any tricks on it and damage the componets, my previous board being a perfect example. This is the same longboard as found in this one http://www.youtube.com/watch?v=4kAZj_Zz4ro. I have had no problems with that one so why the change? I simply wanted more of a selection of modes and I was getting sick of seeing the altoid tins. While they serve as a great housing for circuits they are not weather proof. Mine got all rusty and started to become weak. If you are interested in this then I will show you how to make one! Watch the video in the next step! I explain a few things and show a full demo!

Step 1: Watch the video!

I was inspired by someones comment to me to improve mine.

I just finished making a similar set up with the power supply you have shown. I havent hotglued the circuit board yet. But while testing the lights out with two 9v batteries in series, I noticed that the 12v regulator seemed to get pretty warm rather quickly. Is this normal?

Yes it is normal. Linear regulators dissipate unused voltage in heat. If it is warm and not insanely hot it should be just fine. I would suggest adding a heat sink for added peace of mind. If you're using really good batteries like duracel, that could also be the reason why it's getting warm but like I said it should operate just fine. Check out my recent led skateboard build I made for Andy Schrock! I used a better power supply. Here's the link. Also if yoh have any more questions feel free to ask :) http://m.youtube.com/watch?v=Ek8ZP3f985Y

OK, Thanks. I rode it around a while and it never got too hot, just rather warm. And I did use Duracells. My next version will incorporate a lithium ion battery like you used on that video. I found a battery on ebay. Where did you get your 12v booster and charge cont.?

So let's say if I wanted to use AA's instead of 9v batteries, could I use an 8 AA system (12v) and just skip the 12v regulator overall?

Absolutely but after a few hours of use the voltage will slowly decline thus the leds will get dimmer. Voltage drop will impact that set up. I recently made a better one using a lithium ion battery circuit. I personally would suggest something around that area for best results.

do i have to take the circuit board out of the powersupply or if i have the charger can i leave it in? and on the LED strips of 8 do i strip the glue on top of just at the copper ends?

steo4 shows the charge regulator being connected to the rgb remote receiver board. the output of the regulator is connected to the positive input on the receiver. then its grounded to the center pin of the regulator. the schematic is available in a previous step. you don't have to take the circuit board out but I did to have solid connections. and only strip the clear rubber off the copper connections

in step 4 what is the second circuit board which looks like it has glue all over it and the capicators connected to it?
