So I was looking at the proffie board for a muse for a poi/flow arts open source board and I wonder if adding voltage booster to 5 v and level shifter would increase run time… because higher voltages.
or is still the n mosfet work with longer run time because those will turn power into heat…\
ALSO DOTSTARS, is the min voltage about the same as the neopixels?
In theory, a voltage-to-voltage converter could increase run time, however…
FETs are very efficient, (resistance in millioms) and the voltage from the battery tends to be near what is optimal for neopixels, so voltage converters are probably not worth it. If you want longer runtime, adding bigger battery, two batteries, or using replaceable batteries is probably going to help much more.
As far as I know dotstars behave very similar to neopixels in terms of light output and run times.
Ya. I found one converter but its more limited in amps. so like 60 to 100 pixels. max.
In poi the room is kinda limited. Contact staff / dragon staff you have a bit more room… but Its still tight.
Also as you add weight, they get more nose-breaky.
What about less LEDs, more diffusion?
Are you doing sound for these? Curious about your design 
The dj brings the sound…
thats how flow arts like poi and contact staff and fans and contact sword. and…
I’ve been to a few spin jams . Might have even hosted one or two way back. I stopped when I looked out my rear window and saw a new friend doing fire breathing. Luckily my neighbors were cool back in the day!
I’ve been doing ‘Indian’ clubs lately…really helped my staff spinning! Considering Proffie applications for where fitness gear meets flow arts now.
Anyway, proffie’s form factor and effects are great and I’d love to see them in poi. Especially with some of Fett263’s gesture and timing dependent changes.
Still waiting on dotstar support though. For no sound and dotstars, have you considered these:
I don’t think it’s open source, but it’s a pretty friendly community.
I prefer more fire eating than breathing… lamp oil gets all over my face.
Pixal blaze would be awesome if it was opensource. but its not. also I dont know if it can do POV.
Because thats as pricey as a proffie board. Its like 5-8 bucks to make.
Could always put on the black hat can copy it. or just make a wled board…, or the thing I am doing which is expanding someone elses opensource project…
it doesnt have any usb nor no charging.
You are juggling Indian clubs?
It might be better to use a teensy for this, since it it has a much faster CPU, which should be able to run complex blades at very high frequencies. Combine that with dotstars and you would have something pretty amazing I think.
A teensy is also fast enough to do POV-from-sd-card effects which would allow for nearly arbitrary long pixel streams…
This is an expansion on a another pov project someone is running and its using an esp32 c3 its got an app…
They dont have motion my. goal is to add that and make it like the proffie of flow arts. btw how compatible is esp32 with proffie os… it would be nice to have simple one button ui. No sd card needed. small is another goal and motion and syncing between modulales via espnow… also make remotes. I mean sd cards would be nice.but that seems like a lot. also dotstars and neos…
and add in custom for stalls. and a playlist for shows.
I also want to build a itty bitty board for a one or couple led to add to poi handles.
like these but I want to control the colors…
Its looks like a attiny85 with a charge circuit a totally what custom board stuff is for…
this si the current github for this pov poi
and her is another pov poi that is less polished but has motion
Ha, no I’m spinning them to keep my shoulders in shape. No releases.
Did some reading on your TeensySaber 4 progress and I think you stopped working on it.
From a brief search that Teensy 3.2 is being phased out. Coincidentally, there was a recent drop and a few are available:

That big red warning about discontinuation at the top is a little discouraging though.
I really want to get those dotstars running, so it’s tempting…
Any hope for the v4?
I am a swimmer so I am pretty strong and flexable in that way. I have stopped because I felt too bulkly.
It’s not well tested, but ProffieOS should work just fine with Teensy4.
I haven’t tested the Fastled support (dotstars) so there might be some rough edges there.
For POI with no sound, you would want an external motion sensor, and a FET for cutting the power to the LEDs. (Both are optional.)
Totally. motion for POV poi makes the image more stable and looks clear. also you can do fun things like changing behavior when slowed.like swap patterns and set pattern to just play at a steady rate under a certain lack of spin. and you can set the axis of spin.
already added the N channel mosfet.
I need to learn to program button presses. for my poi handle project. which I think is just going to use neos and fastled. and I got to figure out how to do patterns of on and off or color. I read code pretty well and can redo examples from from scratch is hard.
