LED poi ball and advice about making LED toys

I ordered this 'happy spin poi ball' from raveworx.com. Well it broke within one day. OK I'm a beginner with poi and I dropped it a few times. Still, a poi ball has to be strong, right?? I wrote them an email saying I wasn't going to buy their stuff anymore because it was poorly made. They offered me a lifetime 5 percent discount. Hmm... sounds like baloney to me.

So I took it apart and tried to fix it. One of the wires had broken and then the other one broke too. Well in order to solder the wires correctly I had to test them. Although the unit worked on 4.5 volts, the only thing I had to test it was 6 volts (4 AA batteries). Yeah the lights blinked, and I managed to solder the wires...but they just wouldn't light up.

Boy I was pissed off, I worked so hard to fix this crappy little toy. I wonder what I did wrong. Do you think I fried the mini-transistors or chips by applying too much voltage? How sensitive ARE these things?

In a related topic... I have these little blinker circuits with 3 LEDs, I took them out of some Halloween rings. I would love to put them into something that I could attach to a string and spin. Like plastic toothbrush holders or travel pill boxes. Main problem... the switch is a tactile switch that automatically turns off after a few seconds. I wonder how I could rig this so it would stay on until I turned it off.

My main problem in making LED lights is... something to put them in, switches to turn them off etc.

Anyone here make small LED toys?

  • unfortunately you may have fried the LEDs with over voltage. You can test if the circuit is still alive by touching the leads of a good LED to the old ones (remember they are polarized). You may be able to rescue the toy by replacing the burned out LEDs.

    It it indeed hard to make toys from scratch that are durable, soft and look good. Lots of engineering challenges.

    I've been having great fun with the Yoho glow poi, $20 from coolneon.com. rugged, good looking, not terribly hard.
