"Don't worry about what anybody else is going to do… The best way to predict the future is to invent it. Really smart people with reasonable funding can do just about anything that doesn't violate too many of Newton's Laws!"
I wanted to share my experience using the SpokePOVs in what would be considerd “harsh” conditions. They not only survived 12 days, 2 rain storms and masses of playa dust, but worked like champs- all 6 on my BurningMan bike. Photos that it actually happened are attached
This is a testing rig I constructed for my SpokePOV kit. I used an old bicycle, ceiling fan motor and wiring from an old lamp. It works great as a bench test rig when programming and testing my SpokePOV boards on the wheel. It could also work as a cheap display device.
Unfortunately, the SpokePOV is only one colour, and the m132s, as I understand, doesn’t have the ability to display images. Besides, I think these are a little too expensive for something that I will not use often.
So I though I would try to make my own with components I already had around. This way I don’t have to spend any more money to try and play with a bicycle POV.
This project features:
16 RGB (Red+Green+Blue) Light Emitting Diodes;
Arduino compatibility (Suposedely, I’ll have to check that later);
Single layer printed circuit board, suitable for home fab;
All through hole componentes, suitable for beginners;
Hall effect sensor, for image synchronization;
Least number of componentes possible;
Unfortunately, only one side of the wheel is illuminated (check update).
Fits 26″ wheels, I haven’t had opportunity to try it in 20″ and 24″ wheels.
This project is also a open project. Anyone who wishes to participate is welcome. The contributions will be added to this instructable and published.
Summer means tank-tops, air-conditioner installation and new kits!
This kit is something I’ve wanted for a while. Its an all-through-hole USB AVR programmer for a bit over $20, with both 6 and 10 pin cables and a jumper for powering the target board from the USB hub’s 5V power. It can also be used with SpokePOV kits to upload images and configuration (finally!)
A simple open-source USB AVR programmer and SPI interface. It is low cost, easy to make, works great with avrdude, is AVRStudio-compatible and tested under Windows and MacOS X. Perfect for students and beginners, or as a backup programmer.
The project is based off of the USBtiny code & design. The main improvements are: adjusting the code to allow it to act as a SpokePOV interface, adding lowlevel bitbang commands, and addition of a “USB good” LED. Other changes are new VID/PID (to make it official), removing some of the commands, and moving around the pins a bit.
You can build this design using the schematic and firmware, or buy a kit from the Adafruit webshop. Having a full kit available solves the “chicken & egg” problem of purchasing or building a USB programmer that then needs a programmer of some sort to ‘kick start’. (See USBasp, AVRdoper, USBprog)
All the firmware code is distributed under the GPL, the hardware design layout files are CC 2.5 Attrib./Share-alike
I’ve completely revamped the SpokePOV software for both Mac OS X and Windows. The interface is better, the image handling is nicer, the download/uploads are faster. There’s even a debugging wizard that will help you figure out why it might not be working.
If you’ve had any problems before, you should check this out! And let me know how it works for you – good and bad. (Just comment here or post on the forum)
