    Several years ago I bought a PC logic analyzer from Intronix (http://www.pctestinstruments.com).  It is really quite good, but this Analog Discovery product looks much, much better.  Seems like a must-buy.

    If you ever wanted to get logic analyzer, you should take a look at Digilent's Analog Discovery.
    Analog Discovery is a multifunction device developed by Digilent in cooperation with Analog Devices (AD is filled with chips from AD.)
    AD features analog and digital inputs and outputs, and can be used as an oscilloscope, function generator, logic analyzer, pattern generator, virtual I/O, voltmeter, spectrum analyzer, network analyzer, and even power supply. And the best part, it's affordable, especially for US students.
    I got my AD several days ago and let me tell you, AD is a true Swiss Army knife for geeks.
    To show you how useful AD can be, I used it to test new version of my audio analyzer BoosterPack.
    For my tests, I am using oscilloscope, logic analyzer, and waveform generator instruments (AD comes with software called WaveForms, which is a suite of virtual instruments.)
    Waveform generator provides 2 audio signals (via 3.5mm stereo jack) to BP's audio input. A simple tone or a sweep can be generated, so many options.
    Oscilloscope is connected via (optional) BNC Adapter Board and a probe to audio switch's output, so I can see which signal is fed to the EQ chip.
    Finally, logic analyzer is connected to LP's SPI output and displays sampled data.

    At my job, we had a training class on FPGAs; the project I choose to do was a take on a digital theremin, which ended up using a Launchpad with Energia.

    Probably not - I think this is one of those where they cut them up out of recycled electronics. That, and it's encased in some sort of coating now so we'll never know
    Which actually gives a neat idea - someone should make one of these that lights an LED using the energy from the field if you put, for example, your phone near it by using the signal your Android phone sends out for NFC. Then you could encase it in plastic/glass/etc but you could have something on it light up if you put your phone near it, and no battery It would be like waving a magic wand (except you're waving your phone around)

    LariSan got a reaction from vicvelcro in LaunchPad Proto Plate- from Ponoko   
    I had a few of these "protoplates" made-- I fell in love with the one from AdaFruit for the BeagleBone and really wanted one for the LaunchPad and had some made. 
    (I have to thank Bart, if he's on here, for really making my first Ponoko trial-run so smooth). 
        So here is where you can order the sheet.
    It's 14 total plates on the Plastic- Acrylic- Clear- 3mm- P3 sized sheet, which comes out to be about 3.50 for each plate- total about 46.50 (Bart had free shipping since he's a regular user at Ponoko). 

      I'm sure there is a more efficient way to arrange these to get more on the same sheet (there was a lot of extra plastic that wasn't used). This was a trail run for me. 
    It comes in a large sheet, where you only need to pull off your plate
      I left the backing on the plate--     Added the breadboard:    
    these breadboards from Mouser (I get them in packs of 10 so it comes out to be about 4.95 a piece)
      The hardest part was to figure out how to connect the LaunchPad to the sheet.  Even though it's nice that the rubber feet were already included... it turned out to be inconvenient. 
    The BeagleBone and the Arduinos have screws that allow you to use standoffs.  In this case after trying: hot glue, epoxy, these scrapbooking "zots" (super strong adhesive tapes in dot shape) and double stick tape and found out that all of them don't adhere to the rubber well.  What's worked is Crazy Glue.      Put it on the LaunchPad, set it down and let it dry...    then I peeled off the backing.        I'll get to test these in a workshop soon, but so far I like them, but plan on changing a few things.  I have about three extra that I wouldn't mind sending to anyone who wanted to see it.    It's hard to know which direction is up... I have two sleds and one is right handed and the other is left handed... I guess if I just removed the logo all together I could have it be either right or left handed      This is what I think my next one will look like, but I'm completely open for any suggestions!     Hope that's helpful, I've included the files to make the edits in my dropbox (it's in illustrator and the forum doesn't like the format for some reason). https://www.dropbox.com/sh/6tho7jrplryvyhl/PJAJ22XqpQ

    Here's a couple of LP v1.4's that I built from the legacy PCBs kindly donated by @@LariSan. Soldering the LEDs was a bit tricky as the 0402 pads are closely spaced and I only had 0805 components. In fact the soldering generally wouldn't win any awards, but even so I am pretty happy with how they turned out. Thanks BluHash for distributing these through the 43oh store!

    The DIY Launchpads are middle and right. Yeah, the short ones with the orange tactile switches and green green LEDs.

    Found these at one of my favorite stores for small parts: http://www.taydaelectronics.com/premium-jumper-wires-female-male-200mm-pack-of-40.html.  Tried to find some one eBay a while back and couldn't find a good source.
    Great for breadboarding with the LP.  Thought @@LariSan might be interested in using them for classes - 20 would be enough for a student.

    If anyone is planning a CC1200 (or CC11xx) booster pack for this, let me know. I'll support it. I've already done considerable work with the EXP-5529 board + CC110x, and I'll happily port to 5529-LP. It would give me an excuse also to hire an intern to finally finish the RTOS-managed, threadable Energia fork I've had on my todo list for a while.

    Did you guys notice TI's selling their new MSP430F5529 USB Launchpad board? I found an old announcement back in 2012 on 43oh main page that TI's working on it but haven't seen any on it being sold. I just found out today and apparently it's sold out. :-(
    TI also changed the descriptor tool by making the interface a bit prettier but they removed the definition USB_MCLK_FREQ which will break all the code in their last USB API so now there's a new USB API 4.0 that requires CCS 5.5 to be installed, though there are workarounds so it will work with existing CCS.

    You are amazing. 
    I have been so overwhelmed with getting things going for this huge education show we are doing in Atlanta, when I came in and saw your package on my desk. 
    I opened it and immediately loved the FTDI breakout board , but what I REALLY REALLY REALLY love (I can't stress that enough here) is the adapter board you made! Not sure if I'm just late to finding out about it until that moment it came out of the envelope, but you have made my ENTIRE week. I don't have time yet to write the blog post I need to about LaunchPad + Beaglebone in Education, but your "BoosterPack Cape Adapter" fits perfectly!
    I was so psyched that I actually rescheduled a in person meeting to be on the phone so I could solder the headers on and try it out
    Anyways, THANK you for sending me a few samples and when I get back from ASEE, I hope to have the post out on the e2e blog roll so you can see how your board fits in with all of the other University tools!
    And yes, I will be sharing them around the office!
