LED Hoop AA Battery Upgrade
Power your LED hoop with a single AA battery, rechargeable or alkaline. It can power 21 LEDs for about 3 to 4 hours and can be swapped out for a fresh AA at any time. Perfect for hooping off the grid, in the desert or on the road. Carry a few AA’s and you are set for hours of hooping. Swap batteries in a flash. Never wait for a charge again!
The basic kit includes one AA circuit module and one AA battery holder. You’ll need to solder the AA module to the switch, LED wires, and battery holder according to the diagram below. So this is not recommended for beginners or those who have not soldered before. Read full instructions before purchasing this kit.
In order to swap out the battery you’ll need to open your hoop, so you will want to file down one end of the tube connector so it can be easily pulled apart, if that had not already been done.
NOTE: you must use a minimum of 7 LEDs in your hoop with this system. Connecting this system to fewer LEDs will over-drive your LEDs with too much current and damage them. So do not connect less than 7 LEDs even when you are first attaching you LEDs to your wire

Hi there! I was just at Ultra Music Festival and a girl let me borrow her LED hoop, and she said she got the kit from you. So now I’m thinking of getting a DIY from you, and am trying to figure out the best battery option. I’m thinking that the AA’s may be a good idea. Is the AA option just as bright as the regular batteries and the rechargeable? And when assembling the hoop, do I follow the same instructions? Thanks!!
Im not surprised to see ProdMod hoopers are so friendly. The AA option will be just as bright as the standard non-rechargeable battery. But not quite as bright as the rechargeable version. If you want to make it really bright you can add another AA battery to it in series, but it takes more room away from the LEDs. Keep in mind the AA option requires some soldering at least to the switch. You can buy it pre-soldered by choosing the option above. Either way you still need to connect it to the LED wire and battery holder which can be done by soldering or twisting the wires together and taping.
Follow the basic hoop instructions until you have to install the switch at Step 10. Then follow the diagram above to insert the module and switch. You don’t attach the battery holder until after you install the tube connector in step 11.
Re: DIY LED Hula Hoop New Ideas thread.
There already exists a circuit module that allows you to power a DIY LED Hoop…
Hi there!
You mention that the hoop lasts 3 to 4 hours on one AA battery. How many LEDs are in a hoop that lasts 3 to 4 hours? Is it 7, or will it last 3 to 4 hours with more LEDs?
Thanks!
sorry I guess it creates ambiguity with that statement of 7 LEDs. I’ll change the wording above. I tested this AA circuit with 21 LEDs and it lasts 3 to 4 hours. I’d have to test it with different amounts of LEDs to tell you if it would last longer or shorter. Did I answer your question so far?
Just assembled 21 light purple led’s with the AA Upgrade…There does not seem to be enough juice to power the LED’s it looks like a minimum of 3 volts when I hook it up to a power supply…After completing the wiring, the circuit module does not seem to allow any current through. Any advice?
I heard another buyer mention similar issues with UV LEDs. I am out of town now but plan to address this when I return next week. It may need a different circuit. I`ll post about the solution as soon as I have it.
sorry for the inconvenience.
I just re-tested this AA circuit with 21 light purple LEDs and 21 UV LEDs and they both light up fine. 7 LEDs will be brighter than 21 but non-the less they all light up. Are you sure that the orange and green wires are connected to the LEDs and red and black is powered by one AA battery? I used a single AA NiMh with 2700mAh. And I also used a 1.5 V Duracell alkaline battery. both worked fine. The alkaline was a bit brighter.
Also you must be sure never to power the circuit until after you connect LEDs to the orange and green wires. Powering the circuit without LEDs properly connected WILL damage the circuit.
We ordered 84 LED’s from your site, so that we can make a few hoops. We are currently exploring out battery options. We were thinking about putting rechargeable batteries that would be charged on a wall charger in our hoops. When we went to the store we found many different types of AA battories, rechargeable and otherwise… any advice. (we may use more than 21 LED’s.)
I really want to make some mini LED hoops with 3/4 OD tubing. Would this battery system fit in the smaller tubing?
The AA battery holder is actually too fat for the tubes that have inner diameters of 0.625, which is typical of the tubes with 3/4″ outer diameters.
But you could use a AAA holder instead. Downside is that the hoop wont last as long with a AAA as it does with a AA battery.
