I wonder if the microcontroller can poll the accelerometer fast enough to keep a pattern stable as the ball rolls? It'd be cool to see a Pacman or an eyeball or something that always points 'forward' as the ball rolls.
@TheRailroad99 2 роки тому
should be possible. the minimum ODR for most of those (haven't looked at the one Carl used) is 25 Hz (which would already be quite good) but they can easily go 100 Hz+ which should be enough. However I don' know if this would be physically possible, since this might also need a gyro sensor. one way or another you would probably need to calculate and subtract the centrifugal forces from the ball spin

Nice! I've been wanting to do a led sphere for a while but couldn't get my head round teh geometry. Re. the reed switch - you can get some very low power hall sensors that only draw a couple of microamps, which will be smaller and more sensitive. Magnet sense to switch on, auto poweroff if no movement for a while. I'm not surprised the adhesive peels, as this stuff doesn't work long-term if there is continuous tension on it. Maybe tack down with UV glue, or have the ends soldered together at the tips.

At work on lunch watching this video. Altium Designer Mentioned. Look at 2nd screen where I am currently working in Altium. GRIN Granted Altium Designer is VERY expensive, however Altium does have other PCB design tools targeted at hobbyists like CircuitStudio and CircuitMaker. (they however dont have the full capability of Altium Designer obviously)
@CTCTraining1 2 роки тому
Excellent project although I’m amazed it stood up quite so well to the battering. Perhaps embedding the leds into a cast bouncy ball might give additional resilience and inductively recharge the battery? “Games in the Dark” could be good idea for next Xmas. Good luck 😀👍

Slight sw improvement: 1. Create a 3d map of the LED's 2. Calculate the impact vector upon hit 3. Sweep a plane through 3D space along this vector 4. Update LED's according to when passed through their coordinate by plane = success.

@KeithOlson 2 роки тому
Cool build! Some thoughts: 1. What about using inductive charging? That would eliminate the need for external wires and the charging circuit could be set up to disconnect the battery--and thereby turn off the LEDs--until the unit is removed from the charger. 2. A TPU diffuser/cover would absorb more force. You could also put the whole thing inside an actual ping pong ball for added protection. 3. Instead of having magnets directly holding the two halves together, a solenoid--or two--could release a mechanical latch--or two--when the IMU detects a particular knock pattern. 4. Could the antenna be brought to the surface as a wire or even a trace on the LED part of the PCB? Does that make sense?

Challenges for another version: Make it charge wirelessly and print the case around the ball. Pause the print half way, put the ball in, then continue print until the case is done, this will make the outer shell much stronger.

A wireless charing loop might be a good way of recharging it. Perhaps you could even charge it over multiple charging points while it's rolling around... NFC or Wifi could be used to turn it off, and you could potentially use the lower pwer/sleep modes of both the gyro and the cpu to detect movement and turn it on, and then turn off after no movement detected after a certain amount of time. Just random thoughts...
@AzaB2C 2 роки тому

@MultiMegaMaxx 2 роки тому
Having 2 halfs that screw together seems like it would be a good bet and strong enough for the ping pong test. Perhaps a qi charging coil for wireless charging would allow you to permanently seal the pingpong ball since you already have wireless programming? Very cool project!

@tonywharton5220 2 роки тому
Adhesive doesn't stick to filament printed parts unfortunately. If you sand the surface smooth, you will have better luck 👍 The other alternative is to print the ball in resin?
@BEdmonson85 2 роки тому
I was thinking the same, the surface area is reduced due to the layer lines. Resin is probably a no-go unless he uses some crazy strong engineering resin. Even the flexible resins available to us hobbyists would crack after a while due to UV exposure.
@tonywharton5220 2 роки тому
@@BEdmonson85 The UV problem could be overcome with a UV resistant spray making the surface even better. I honestly don't think it would crack, depending on the thickness. But you are right, resin prints can be brittle if not cured correctly.
@BEdmonson85 2 роки тому
@@tonywharton5220 Yeah I didn't think about the UV protective sprays. One other consideration is weight. Resin tends to be heavier than plastic.

You should make a version two that has wireless charging and a custom ball holding wireless charging base. Then you could check if it is charging is if charging turn the lights off. But you could also watch for taps while charging and if tapped cycle through some options. (Solid color (more taps change color), cycling, strobe, random, etc)
@SirRodney42 Рік тому
Do you need the inner ball? Why not glue or friction fit the leds in the outer ball? That would save weight and you then have room for a bayonet locking mechanism in the middle.

@bloodaid 2 роки тому
Would it be possible to get custom manufactured flex OLED display? I believe it would lower power consumption drastically and also weight. Also a different MCU and a slightly smaller battery could lower power consumption and weight. Finally if there would've been a regenerative power mechanism that picks up some power from each hit, the battery could last a tiny bit more. This little cool ball of yours could def be optimised.

@alexstone691 2 роки тому
Im guessing putting some epoxy or something rubbery over the leds could make them survive easier and hold the integrity while possibly being more bouncy? Also isn't using wires between the hemispheres and the main board more durable than flexible pcbs For charging i would either put the pads into holes and wider apart so you couldnt really short them, or maybe just a diode? so it can be charged but not discharged? but that would require the charging circuitry be inside as well Great project though :D

What if printthe circuit board into the model? print half stop the print. Put the electronics in, and continue print? I know cura has some settings like.
@kid_named_fingers 2 роки тому
Adhesive didn't stick because you should've made internal hemispheres more smooth and in latitude-rib style. Probably some kind of solvant(acetone) should work as smoothener for the plastic.
@kid_named_fingers 2 роки тому
And i think outer shell is more than enough. Instead of internal sphere some kind of skeletal structure should work best.
@wiiu7640 2 роки тому
A major problem is the deformation of the outer shell which traditional filaments will do poorly at. I would try making some spring action for the LED sphere and making the outer shell a flexible filament so that it doesn't break when being hit repeatedly over a long period of time.
