Posted:Hi everyone! My first thread here - yay! I got fed up of stinking of paraffin, so I've just started building some LED Poi and judging by the prototypes I built, they're going to be BRIGHT.

Per Head :
3 x AAA batteries
4 x Super Bright LEDs

Each head should be about 240mm long and 30mm round, giving off a bar of light 18mm by 30mm. At the moment, I'm running the LEDs at about twice what they're specc'ed for so I'm not sure how long they'll last - time will tell. The LEDs I have now are blue, but I've seen some green ones which are ~3x brighter!

Has anyone played around with PIC Microntrollers? They're what make the Aerotech staffs etc. work, and I'm thinking of modifying the POI I'm working on so that they can flash different colours / patterns and stuff...

Posted:I must agree it is soo much fun making LED poi. I think I have about 50 prototypes sitting in an old cardboard box.
Mum used to get pissed at me covering the kitchen table with wires and stuff biggrin

LED's have really advanced over the years, which is great ubblove

Look forward to seeing your poi in action

Cool! Just make sure you don't create a fire hazard. If you're running these things higher than they're supposed to be, things could get a little warm!! I'd hate for some sock LED poi to turn into fire poi mid show!! Actually, that' would be kinda cool, lol, but not with that kind of equipment, so be careful!

And by all means let us know if you come up with any magical designs!

Posted:joulz : Not quite like glowstick form. The batteries run down the center and the LEDs are arranged around the outsides. I'll try and remember to post a picture of what I mean this evening...

Big Andy : Point taken - I shall keep an eye on how warm things get although I reckon that when they're swung around, the air will probably be enuogh to keep them cool. We'll have to wait and see smile

Posted:eek eek gosh, reading this thread just brought back a dream that i had last night - i got whacked round the head by something really hard, turns out some kid had thrown something really nasty and heavy at me (as they do).. then was about to throw it away and noticed it was a flashing green and red ball and was like "oh wow, LED poi, i'll keep that!" and then realised i only had one and had to find another......
it's always fun when random things bring dreams back to you, so sorry if that was dead boring but i thought i would share it here anyway ubbtickled

I have a reasonable idea... *pokes at the various bruises covering his legs / head / arms etc* ...which is why these ones will be covered in foam.

The aluminium bits arrived last night so I built a really crude mockup. Looks like these are going to be awesome - and not too heavy either. I reckon they'll probably be lighter than my wicks!

Apologies for the lack of piccies - I'm moving back home with the folks for christmas and packing took longer than expected.. rolleyes ..I'll try and get some tonight instead biggrin

I've now made the Aluminium parts I need. With a bit of luck, I'll have the first version (constantly on with blue LEDs) working on Weds. If I manage that, I'll post some more pics smile

I second the motion-please make a tutorial for building those- I want a pair in the worst way now! biggrin

At the moment I'm working on my own homemade set of beginner's poi- I will have to post instructions for those too, they're coming along very well so far.

and why do people call me a raver when i swing glowing stuff, and a firedancer when i do the exact same thing with kerosine?

has anyone thought of having the batteries on cuffs on your wrists. ok so you cant let go but it means you have the reduced weight and can get back to fast glowstringing.

*gets out rubber stamp that says "JADED", smacks darkpoet in the head with it*



No, just kidding, you're absolutely right, but let's face it, alotta "ravers" are addicted to speed when it comes to glowstick poi, so electronic glow poi that are light enough to spin at blazingly fast speeds are not without a customer base.

The "duct tape a rav'n in the end of a glowstick" thing is still my favorite home made poi idea to date. So easy, so cheap, and so cool lookin!

Those look neat from the pics though, Fire Geek! I'd like to see those in action.

Posted:Wow, been a while since I posted on here, but I'm back again smile Unfortunately, most of the metal parts for these were machined on a lathe.. but I bet you could make something similar out of plastic!

The actual electronics are pretty simple - four super-bright LEDs (in parallel) atatched to 3 AAA batteries. If you'd like a diagram, I can provide you with one.. ?

I got the batteries from eurobatteries.com (AAA NiMh) - 1.55 per battery, but they're rechargeable.
LEDs came from led-lights.co.uk - 1.32 each

Bear in mind that you need 4 LEDs and 3 batteries per head so ~9.93 per head. On the plus side though, they're rechargeable and in my experience, will still be super bright after 3-4 hours use!

I really need to get round to ordering the parts to make a flashing circuit so I can flash different colours, speeds etc. Sounds to my like dark poet is already onto this though biggrin

re FireGeeK on another thread.
How are you mixing them? Just two colours on at a time? I plan to strobe mine at speeds higher than the eye can perceive to mix the colours more effectively. I've not (yet) tried this, but it ought to work - that's how computer monitors work after all (well, sorta )!





thought this might be a bit off topic for the Luxeon thread.

At the moment I'm mixing them two colours at a time, each light at 100%. I'm trying to find a way to specify how much power to provide to each light, which should allow a huge variety of colours. I tried using Pulse Width Modulation , which might be similar to what your planning to do?
I'm using relatively cheap controllers for my poi and while they do PWM it's unusable because it's low speed (something like 100 cycles a second) and you can clearly see the off section of the strobe when the poi head is in motion. More expensive hardware or a pure analogue circuit should get the frequency up, but it starts to get expensive or requires more experience than I have.

As far as mixing the colours - you might not _need_ to strobe: movement is your friend here. I'm using 8mm LEDs at the moment, positioned side by side on the end of the PCB, so two of the colours are about 10mm apart. When held still they don't mix very well at all, but when in motion it mixes perfectly.

peace
