eWheel Velo Bling-Bling Freescale Project

So here is a really, really cool project: eWheel Velo Bling-Bling:

‘Velo’ is the local Swiss term for ‘bicycle’, and no, this is not my project ;-). It is the one of Peter Schmid. Peter wanted to say ‘thank you’ for some of my blog pages. And I want to say that Peter did an awesome project!

The concept behind VeloBlingBling is POV (Persistence of Vision): a series of LED is rotating and moving fast, controlled by a microcontroller. If the LEDs are turned on and off in a fast and synchronized way, it creates the vision of a steady or moving image:

Peter created the first proof of concept with a Freescale FRDM-KL25Z board and Arduino Prototype-Shield:

The first prototype has been built with a Freescale KL25Z128VLK4 device and 16 LEDs:

And here the second prototype, mounted on a bicycle, with a Freescale MK22DX256VLF and 32 LEDs (16 on the front and 16 on the backside of the PCB):

Technical specs:

  • Built-in bicycle-meter (distance, speed) including barometric pressure measurement (altitude), temperature, time, stop watch, …
  • 32 LED’s (16 each on front/back side)
  • Configurable with Bluetooth Low Energy (BLE, Bluetooth 4.0) (e.g. with Android 4.4+)
  • USB connectivity
  • Hardware includes charger for LiPo (700 mAh) using micro-USB connector
  • Start/Stop button
  • Up to 50 loadable images

For all the other details, check out his website (in German): http://veloblingbling.ch

Peter is still undecided if he should make it a commercial product or not. Or what about making it Open Source and/or providing a kit? What do you think?

Happy Bling-Bling-ing 🙂

  1. Hi Eric

    I like the project but the idea has been commercialised some time ago by a number of companies/manufacturers:

    You can order some quite advanced ones in Switzerland for under $80: http://www.veloplus.ch/AlleProdukte/Beleuchtung/PARTYMONKEYundMINIMONKEYRadlichtervonMONKEYLECTRIC.aspx
    Of course, an open source project would be interesting for peope who want to buid them themselves, but I don’t know whether they will be able to do it much cheaper.

  2. Kudos to Peter for sharing it – fantastic if you wanted to let it be open source.
    From the product managers that I’ve known – roughly 50% of the effort is in development and 50% is in marketing, pitching it,building contacts – so for commercialization you need to find a company that can buy it outright – perhaps exhibit at a maker faire.
    Thanks to Mark for providing other references, looking at MonkeyLite M232 Us$59 – after the electronics and software smarts – there are still all the mechanical design considerations- battery powering and mechanical sealing for a harsh environment on the road.
    If Peter did want to open source it – it might be possible to still get some revenue through say sparkfun.com, or other maker type places. – but I’m guessing there are headaches for defining a toolchain for this K22.

    The tool chain should be the least of worries since Freescale supplies their free and unlimited KDS (Kinetis Design Studio). Of course it would need to have some form of debugger integrated to allow it to be used by hobbyists who don’t want to purchase a JTAG debugger to connect with (the OpenSDA chip can be put into the HW if needed).

  4. I agree with neilh20.
    It’s a very interesting application, altough I don’t know if it has a BIG commercial value. I think he should consider the effort necessary to make it recognised on the market, production costs etc. Developing a prototype is relatively easy, but mass production is another thing.

    I don’t know if is the case, but in my opinion most people that thave technical knowledge have more difficulties in dealing with the non-technical parts of making a product and putting on the market. If he has patronage, any kind of support or partner, things could go forward.

    Making it open source and be opened to donations is the easiest way to make it worth, but of course it is not the most profitable. I think he should think that.

    For the people in general, it would be great if it were open source and even with a kit =D.

    And with my limited german skills, Gut Arbeit von Peter, ich wünsche ihm viel Glück in dieses Projekt.
