Daylight is drawing in earlier and earlier every day and because of that, lights are extremely useful when using the Diabolo during dusk. Not only that, it looks frankly amazing. It also means the monthly Firejam in Castlefield bowl has started up again.
Dusting off my LEDs and adding them to the Diabolo again. However there is a problem. I am pretty much in love with Sundia Diabolos and the battery in my Sundia LED kit is pretty much dead. Can I get another one? Not a chance, its sold out everywhere it seems.
After unscrewing the LED kit, I noticed a small rechargeable battery like the Pacemaker one. Currently it all works when plugged into MiniUSB (bottom left), which clearly suggests the battery isn’t holding any power anymore. So I decided to look into getting a replacement battery because its worked so well for my Pacemaker device and I’m about to do similar for my pebble smart watches.
However I can not find the battery type or anything about it. I assume its a 3.7V tiny lipo Li Polymer rechargeable battery with a connector but I can’t confirm this at all. Both sides of the battery have no details except a slightly faded Sundia wording. I also don’t see anything on the circuit board but I’m sure someone reading knows or can help me.
I think this might do the job but anyone who can point me would be massively useful.
A while ago I blogged about trying to replace the battery on the Sundia Diabolo LED kit.
Lots of friends tweeted me and helped.
I learned a lot including LiPo is always 3.7v and the configuration of the numbers which were faded out on the current battery. With that information I finally bought some batteries from ebay.
They took a while to come but I did a few rough tests and it seemed to work and then not work. So I left it, however I now know the reason why it was on and off is because of the wiring.
The wiring was small and trying to bind the wires with my large hands was always going to be a problem. In the end I finally got it hooked up and stripped the wires back further than originally planned. Once done, it was stable and I was able to make it work consistently.
What it really needs is soldering because lets be honest its going to be thrown around a lot and the impact on my black tapped connections will be high. Because of this, I’m considering adding foam or bubble wrap to the inside of the case to put less pressure on the inner elements. Ultimately they should be soldered and the battery stuck in place with something stronger than black tape.
Ironically I decided to get a fire diabolo, at long last. There is something about Fire which is much more impressive but infinitely more dangerous (in a good and bad way).
Update on the Sundia Diabolo LED
With the mess which kind of worked, I thought I need to talk to a professional about it. My good friend Jasmine was the natural choice, so with chocolate, a takeaway and some good conversation. Jasmine lent her professional eyes to the LED kit. Fixing everything so well, I was blown away with the results as you can see above!
Now thats how to fix the Sundia Diabolo LED kit!
