    "Order Sample Kit Now" red button below the schematic. Limited to 1 kit per person.
     
    There is no stock at the estore now but it does say accept back order.. Honestly I have no idea what this is for, all i know is there are 3 parts that come with this kit (for controlling motor drive).

    Done
    (19th Nov).
     
    ----------------------------------------------------------------------------------------------------------
     
    Is anyone doing work on the CC2500 other than GW. I found this link and each unit is priced at $1.8. Shipping is ~11 via China post and ~$25 via EMS.
     
    I was wondering if we could do a group buy(I'll organize). I'll have it shipped to me and then to you guys.
     
    Cost breakup for 20 units:
     
    Unit cost: : $1.8
    Postage within US: $1.71 via first class mail
    Shipping from China breakup: $12/20 = 0.6
     
    Total: 1.8+1.71+0.6 = $4.11

    MattTheGeek got a reaction from djun in [RFS]Motion Pack - Let your launchpad sense motion!   
    I've been thinking of creating this for a while, and i think the time is now.
     
    The motion pack is a 6DOF (Or 9DOF if the gyro is added) launchpad booster pack to sense acceleration and magnetic heading.
     
    6DOF version:
    A HMC5883L 3 axis compass and a MMA8452Q (or perhaps a MMA8453Q) 3 axis accelerometer with supporting components.
     
    9DOF Version:
    The 9DOF version contains everything the 6DOF has,but includes a ITG-3200 3 axis gyro. The ITG-3200 has been replaced with the L3G4200D triple axis gyro.
     
    I'll figure out pricing soon... but the 6DOF shouldn't cost more than $19.99 (or even $14.99) populated. But it's a different story for the 9DOF...

    MattTheGeek reacted to bluehash in Get your Booster Packs Sponsored - $10   
    Hello guys..This has been at the back of my head for a long time. So lets start at Booster Packs.

    43oh will be glad to sponsor your initial Booster Pack[bP] development. $10 will be awarded to you to make initial PCBs or purchase parts. It's not much, but it is an incentive. A max of two BPs will be sponsored/month.

    Your selection depends on the following factors:
    [1] Be a member on this forum for at least 4 weeks and have a minimum of 20 posts.
    [2] A thread in the Booster Pack sub-forum.
    [3] Create initial schematics and layouts in the thread, including selection of parts.
    [4] BP usable by a large number of people.
    [5] Open source your schematic and PCB Files. Git it if you have to, but keep a copy on the Forum.
    [6] Some amount of test code if the success of your Booster Pack depends on it.
    [7] A voting system for the community to decide if the BP needs to be sponsored. I'm not sure how many votes make a good BP. If there are enough "Yes" votes(more than 50%) than "No"... your sponsored.

    I can't think of anything else.I'd also like to put a donate button for members to donate towards the pool. Would there be any interest in this? Donations will be made public to ensure transparency. I would appreciate the communities response to the idea. This will also help increase the number of sponsorships/month.

    There is no liability once you are sponsored(since the schematics/PCB files have been shared). It's a matter of mutual understanding that you will not run away with the boards. Maybe give them away with the interested party paying for shipping.

    One thing to keep in mind is to keep this KISS - Keep It Simple, Stupid.
    Also, no arguing, but intelligent debate when voting. This is NOT a competition.

    Whats the trace width of your external power? I believe you might be exceeding the maximum current limits for your power traces. Also try to add a extra via when you are switching layers, as one via might not cut it.

    About early august, a family member died. One month later, my house caught on fire. 3 days later the half of the remaining processions were stolen from the fire damaged house, and I've relocated. It's been a rough 3-4 months.
     
    So whats the good news? i'm writing the the first final release, Version 1.0.x, from scratch, taking in the input from the community.
     
    While i don't have much in equipment and tools, i'll see what i can do.
     
    In short...
     
    I'm back

    @cdch10 In CCS, make sure you've added the EasyMSP folder as an included folder. The best way I've found to set it up is leave EasyMSP in the installed folder, in my case it's C:\EasyMSP. Bring up your project's properties, right-click on the project name and Properties is at the bottom. On the left column, click C/C++ Build. Then under MSP430 Compiler, select 'include options'. Then just add the EasyMSP folder. Also, make sure to follow Matt's instructions. #include "EasyMSP083BETA1.h" and setup();

    Hmm.. I did send kits for you to try out on. Did they get destroyed? If yes, I'll try to at least secure a launchpad for you.

    I think it's very appropriate, it's to show appreciation and to compensate you for the work you have done. Those are pretty common on freeware project sites.

    Thanks for the list. I think I speak for most here when I say that it makes us feel good to be able to help out one of our own.
     
    OK... A quick run across my (fairly pathetic) workbench yields a smattering of semi-useful stuff:
    -breadboard and a few jumpers
    -few strips of header (M/F)
    -various LEDs (sorry, I don't have specs)
    -a few GP diodes/transistors
    -a couple of 3v vregs and a 317
    -a few caps (just about enough to make the vreg circuits)
    -a bunch of 470 and 100 ohm resistors
    -some tactile buttons
    -a couple of proto-boards
     
    PM me your address and I'll send this stuff off and have TI ship a LaunchPad or two direct to you.
     
    EDIT: Just remembered: I have an extra servo I can send!

    MattTheGeek got a reaction from RobG in MSP430G2xx3 Development Module/Board with EasyLink+   
    Hey all,
     
    I've been designing a development board/module for the 28pin MSP430G2xx3 devices.
     

    MSP430G2xx3 Development board/module by MattTheGeek, on Flickr
     
    In addition to breaking out the device, it also features:
    [*]IR transmitter and EasyLink+ Compatible
    [*]On board power regulation and protection.
    [*]A user controllable LED, and a Power LED.
    [*]Button for Reset/NMI
     
    You may be wondering what EasyLink+ is... Well, in a nutshell it would allow users to wirelessly program their device using a bootloader on the target and a launchpad with a special Link shield. It also can be used as a regular IR transceiver or for distance sensing, etc...
     
    Tell me what you think.
