  1. Spirilis had an extra board from the original batch he sent me to try out. Here is a video review of it I made and an explanation of how to program it: http://www.youtube.com/watch?v=GHjFCnXXAoQ
  2. I finally had a few minutes to do this today... Could you check this again? Thanks, Matt (I rotated the 815 optocoupler at U1 - I was going by my misinterpretation of the datasheet rather than the dot on the board. That crap near J7 is just a piece of paper towel.)
  3. What is the purpose of U2 and U3 on the Launchpad (attached to the LEDs)? Part number SN74LVC2G07.
  4. Does that configuration look correct? (I haven't tried powering it up yet.) I also made a blog post to explain what I'm trying to do, in case anyone is curious.
  5. How would you get the phone company to give service for the device you made? I can just imagine calling up those folks and trying to explain how I hand soldered a GSM card to a circuit board and want to get on their wireless network..!
  6. I am ordering parts for Page 5 on your "Pictures of the boards Nov 2012.pdf": I assume the "gate resistor" on R3 is just a standard resistor, not some special kind... the part number you have is a duplicate of R1. Also what is R1 under the relay section? 680 ohm? In your schematic PDF, is it SW2 triac, SW3 SCR, and what is the difference between SW1 and SW4?
  7. Thanks! I was working on some timerA stuff this past weekend so now I have a better understanding of how it works. I should be able to get it working. I'll let you know how it goes.
  8. This is cool. Any ideas for projects using these that don't involve LEDs? Maybe some sort of radio transmitter integrated into one's clothes? Perhaps a shirt that senses the temperature of the skin and automatically warms you in places you are cold (like those electric socks you can buy, except it shuts off in certain areas when too warm)?
  9. Is this board going to be in the store soon? I'm not in a hurry - just wondering...
  10. I found a really good tutorial. Download the C2000 Teaching ROM... it is a bunch of pdfs from a university class.
  11. For the past couple days I have been trying to write a "TCP speed test" which is where my code sends TCP packets through the wiznet w5200 ethernet as fast as possible from a msp430 5-series chip to my unix server, so I can measure the performance of the msp430+wiznet, and also to help me find bugs in my code. So far I have just found a couple bugs in my code from this and am still working on it.
  12. I am interested in the "variety pack" with the TRIAC. This article I just read was pretty good to explain to me how dimmers work. I also came up with a Plan B for having it IP addressable, which is to use an FRAM Launchpad with the SimpleLink wifi module on the RF headers. I don't know how TI fits a wifi software stack in 16KB of memory but I guess I will find out when it arrives. Wifi actually makes more sense than Ethernet, and with this simplelink app I supposedly I can configure the wifi on the Wifi board from my phone. I could then connect to it through my home wifi network and co
  13. Well my plan is basically this: to have a power strip with an IP address. There are a lot of potential uses for it. I would like to be able to connect to my power strip over the internet and toggle things on and off remotely. Lights are a simple example (good for a youtube video demonstration), but I also have some old computers I need to sometimes powerup / reset remotely. Mainly though I am interested in learning - phase angle firing sounds cool to me (dunno, definitely sounds impressive - I have just started learning about TimerA as well. Looking at your diagram you are using P
  14. I ordered a sample fr5969 chip and they actually sent it to me for free. You can then put it in the eval board and use it.
