TUBE SIZE: 5/8"OD (Outside) CONNECTOR SIZE: 3/4"OD XSmall & Small Push Buttons In this tutorial, I'll show you how to make your own Smart hoop using an LED strip.
Please note: I am using a NON-Waterproof LED strip for this hoop. These strips are much lighter than the Waterproof LED strips, but they are not, of course, waterproof. So I would be cautious about getting this hoop wet.
Connecting the Battery Spring to the Push Button In the video, you'll notice that I attach the battery spring to the push button with tiny nuts & bolts. This requires that a small hole be drilled in the end of the push button, which is tricky to do. I didn't have much luck drilling the holes myself, so I took my push buttons to a machine shop & they drilled them for me on a huge drill press. This may not be an option for everyone, so I have been trying to come up with an alternative solution. You can try & solder them on, but I didn't have much luck with that & besides, I really hate to solder! You could try epoxy or glue, but I have not tried those, so I can't tell you how well they work. What I have tried is Sugru. If you're not familiar with it, google it. I bought it at Lowes or you can order it online in many different colors. It seems to hold well & hopefully it will last for a long time!
Using 3/4"OD Hoop Tubing with Flush Battery Holder I haven't made a Smart Hoop from 3/4"OD tubing yet, but if you would like to try it, here's a diagram for it. What is nice about this hoop is that the battery holder is the same size tubing as the hoop tube, so that it is flush. This hoop uses 2@5/8"OD polycarb connectors that are approximately 1-5/8" in length. The connectors are riveted in place, so you'll have to figure out how to do this with the circuit running through them, which shouldn't be too difficult. Maybe one day I will make a tutorial for this hoop, but for now at least, there is this diagram to help start you off!

Just reapply every so often. Battery Dude
If you want to sand them, use really course sandpaper grade (40, 50 or 60). This also provides a good grip, but eventually may lead to cracking or breakage of your hoop.
When I used to tape my hoops I sometimes would use a half inch strip of gaffer tape just along the inside. I don’t really like the criss-crossing of tape that I have seen, although If you need the gaffers for extra grip then its probably a good idea. I have also tried First Aid Clear Tape, spiral-wrapped on a few of my led hoops. It helps for grip and you can’t really see it, so it doesn’t interfere with the lights. But I don’t think its very durable, so if you use it, you may have to re-tape often.
Just discovered this super duper grippy tape by 3M. (Thanks to Caroleeena!) It comes in 1" rolls but you can cut it down to 1/2" or 1/4" strips with scissors to line the inside of your hoop. When applying it, make sure you rub it down really well to get any air bubbles out. It's pretty transparent, so it's great on an led hoop, & seems pretty durable. You can order it from Identi-Tape (bottom of the page) or from Amazon.
