    Hi there,

    Just wanted to run the following past you:

    As a key pillar of the electronics blogging community we have indentified your blog to road test some of our new products we currently have on sale. If you are interested in this scheme then we will happily send you products which will be yours to keep, free of charge in exchange for a review of the item.

    As a high service distributor across the world, Farnell strive to gauge feedback from those within the industry with an online presence in order to make the necessary improvements to our products to delight our customer base.

    Furthermore, we want to build a positive relationship with those within the electronics community as we do on our own community website element14.

    A wide range of products are available to review from a number of high profile suppliers including Tyco Electronics, Vishay, AVX & Amphenol.

    If you are interested in participating in Farnell’s product road testing then please reply to this email and we will be able to provide you with a suitable product to road test.

    You can then review the product based on your experience. All we ask is that a link to the supplier’s page on the Farnell website is included within the review. This is so anybody reading your blog can easily identify where to purchase the product on the Farnell website.

    Thank you very much, hope to hear from you soon.

    Regards,

    Ryan Gibson

      Hello Ryan,

      This sounds very interesting! I’m employed as electronics engineer, so I’m already well aware of Farnell as supplier. Roadtesting products would be very nice!

      Thanks!

    Hi ,

    I was amazed to see your LEGO project. I am working on the same concept but then for a railroad crossing, signals and point control. The pcb’s came two month ago from china 😉 now I’m busy programming them.

    Still some challenges though. Timing and debugging are two hard things on a tiny44 as it turns out (an atmega328 is much easier IMHO).
    I was able to run your code in the arduino IDE, but no good results until now but I will try to persevere of course 😉

      Hi Johan,

      I used the AVR-JTAGICEmkII to debug in combination with AVR Studio, but since Linux is my operating system of choice, most work was done with AVR-GCC and Code::Blocks.

    Hi
    In the spec for the IR protocol it shows controlling the outputs in a boolean mode (Single output mode, data nible 0b1001 to 0b1110). I notice that the the driver you have chosen can’t do this (can’t pull both outputs high), is this an issue to you?

    I ask because I’m designing a similar project and need to decide on a driver too. It seems hard to find a suitable driver that can do this. I don’t know of any Lego devices that require this an I wonder if you think it’s worth the extra effort to implement.
    Thanks

      Sorry for the late answer; this is not an issue to me, because the driver does the same as the original LEGO one

    Hello HvdD,
    interesting discovery the RX-part of LEGO-powerfunctions has an opensource enviroment.
    (I can follow and rebuild this, but development/programming is tough….)
    But my question/remark is about the TX-site:
    The Transmitter of LEGO-powerfunctions, are they available in software + some IR-knowhow?
    Reason: I like Lego RC-trains / PF-trains and DCC, but still running on 12V: http://members.casema.nl/famvollaard/legotrein/index.html
    If I can modify the DCC to LEGO-PF-IR that’s neat step forward.
    Who can support this idea?
    Thnx Roel
