    It sounds cool, but if I want to spend some time battling with buggy MSP430 code then I just write some. I appear to be quite good at that.

    t0mpr1c3 reacted to zlalanne in [Energia Library] Xively   
    Below is a link to a port of the Arduino library to interact with xively for Energia/MSP4305529LP. For those that don't know xively (formerly cosm) is an IoT online service where you can send and receive data from. It allows you to view the data sent in graph form to view trends over long periods of time.
     
    This library requires the HTTPClient Library found here:
    43oh
    Github
     
    Once both libraries are installed you have access to high level APIs to send and receive data to the Xively servers. There are examples that demonstrate how to upload/download a single datapoint as well as an example that uploads to several different channels at once. More information can be found on the github page.

    Mounting holes would be a good idea. I think I'll leave the rear of the ring blank. I'll let people decide what they want to use to drive it themselves.
     
    I'll mock up some simple boards that could mount directly to the ring. Eg the G2553 could easily drive the ring for a simple clock. But for complex animations a bigger part might work better.

    t0mpr1c3 reacted to RobG in 120 LED Ring Clock   
    According to specs, @5V and at full brightness, WS2812 draws 30mA.
    WS2812B is suppose to draw 60mA, but from my experience, it's <50mA.
    At 3.6V, your LEDs will be reddish, but they will still work. 
    LP (G2553) can supply up to 250mA, so we are talking ~10 WS2812 or ~6 WS2812B at full brightness (in practice, you can do a lot more, but color is way off.)
     
    For the ring of 120 WS2812B, I would suggest 5V/6A, so you can light them all up and have consistent color.

    t0mpr1c3 reacted to cubeberg in MSP430 Sewable - any interest?   
    Here are the finished scarves.  I'll upload some closer pictures tonight, including some shots of the board.
     
    The conductive thread was definitely interesting.  What I ordered from Sparkfun does seem to have issues if bent too much.  It doesn't break - it develops kinks that can become hard to pull through, so I had to be careful not to get it twisted too much.  Once I figured that out - it was pretty simple.  I honestly don't know how far you could run the thread - but I've seen projects with traces running several feet.  The thread seems pretty tough too - I'm not overly worried about my kids breaking it.

    Thanks marsbase. I'll put you down for PCBs too.
     
    We are now at 1200 LEDs including extras. I am looking at 12 lots of 100 WS2812Bs from this seller on Aliexpress ($183.43 shipped DHL) or possibly 2 lots of 600 from this seller on eBay ($190 shipped surface). The first option would work out to $19 per set of 125 LEDs before shipping from me to you and Paypal commission.
     
    PCBs will probably take longer than usual because Chinese New Year is coming up. I am planning to use Elecrow (green, 100% E-test, HASL finish). Shipping the PCBs by DHL would be my favoured option. It would cost a dollar or two more per set than HK post, depending on how many we order.

    I am in for 2 sets of 125 LED's 2 sets of PCB's.  I am only interested in the LED's if we are able to get the PCB's along with them.
    No spare LED's.  I have a way to drive them so as long as the PCB's provide the basic DO --> DIN chaining, I am good to go!
     
    WS2812 or WS2812B's are fine as long as the PCB's will accept either.

    Here is an updated PCB. 100% compatible with the old one. However this one features the new WS2812B footprint.

     
    Here is the Altium project files. Includes gerbers and schematics.

    Edit:
    As per @RobG's suggestion this is a moddified version to fit onto a 5cmx10cm PCB. only 5 of these are required to make a full circle. This is an un-proven design, however it was created by placing 2 of the smaller segments together in altium. So it should be good.

    As used in the LED ring clock in quantities of 120. It is a nuisance to buy 200 when you only want 120 plus a few spares. 4 lots of 125 = 500 LEDs which would cost around $85 shipped (surface) to me. 8 lots of 125 = 1000 LEDs which would cost around $165 shipped (surface) to me. 10 lots of 125 plus 50 extras = 1300 LEDs for $196.43 makes $18.89 per set of 125. After PayPal costs that's around $22 just under $20 per lot of 125 plus shipping from me (in USA) to wherever you are. Once we have enough people signed up I'll ask everyone to pay, and once everyone has paid I will order the LEDs.
     
    Datasheet
     
    If people want WS2812B's instead we could do that instead, as long as we all agree. Shouldn't be too hard to fix the LED ring clock design to handle that. I will be ordering WS2812Bs. Greg has kindly redone the Gerbers to match with some advice from RobG.
     
    Post on this thread to sign up, I'll keep a list on this post. Let's try to deal in units of 125. If you would like extras please indicate in your post. If enough people want extras we might get to the target quicker. I can also order PCBs and distribute them, but it definitely won't be worth it for less than 50 boards and it might be a bit marginal even for that quantity. which should present some kind of saving, but I'm not sure how much. 40 5x10 boards from Elecrow shipped DHL cost 4 * $12.90 + $28.26 = $79.86, or just below $10 per set of boards.

    I didn't consider the PCBs because they are a set of 10 already ... easy to order direct from somewhere like Elecrow, plus you get to choose the colour that you like.
     
    There are volume discounts at 50+ boards, and I could potentially mail them together with the LEDs. For now I will just register interest and we will see how it goes. Sound OK?
