  1. I liked the price and I almost did it, but $14 to ship 50 of them seems a bit extreme.
  2. That is a great price on them, I just wish they had a smaller count to buy than 50. I could probably get away with 25, bu 50 is probably pushing it. Thanks for the links.
  3. Where are you guys getting vampire plugs these days?
  4. I had thought about that. How are you doing it? Text? Audio? FM transmitter? Merry Christmas to all! Sent from my DROID BIONIC using Tapatalk
  5. Yeah I just did not too long ago, I forgot to say something about it, thanks for the reminder.
  6. I have a video, but I need to get it onto youtube first. You basically have the idea though: *All is off *Mary/Joseph and farm animals come on *Jesus comes on *The start turns on and then I pull it to its height *The shepard and his sheep come on *Lastly the wisemen and a camel come on *Then they all turn off and the star resets itself The whole process takes about 55 seconds to go through the progressions. Yeah, I was trying to workout something for the pages turning, but it seems like it might be too complicated. The scrim idea is really interesting. I hadn't heard that
  7. This year I automated my blowmold nativity so that it turns on in sequence to tell the story (along with a star that physically gets raised). I think for next year I need to physically tell the story along with the animation to complete the setup, but I am struggling with how to go about it. One thought I had was an outdoor projector that when triggered would show different slides that told the story, but I am having trouble finding projectors that can do that (as opposed to just showing a single slide all the time). Another thought was to have a large book (think 3ft tall) that have
  8. Doh! Not sure how I missed that! You are right. I looked through the specs, but I am not sure what phrase I was looking for, whatever it was, it wasn't that. Thanks for pointing to it!
  9. I have a quick question about the ULN2003. I know that it can handle 500mA per pin, but is there a limit for the whole IC? Can I max out 500mA per 7 pins for 3.5A total?
  10. I have a carousel that is a number of years old that only seems to want to only go in reverse these days. It doesn't have any twists in it and it inflates fine. I had it setup in my garage and let it run for 2 days straight and it still had the issues, so I am not sure what to do. I've read that there is a sensor that tries to determine if there is a kink and will go in reverse to untwist it, so maybe that sensor is broken. I have stopped/started it numerous times, so it doesn't appear to be realizing that everything is OK. My thought is to reverse the power to the motor to force
  11. In case anyone stumbled upon this thread looking for a similar answer, I ordered a Maxim MAX4544 SPDT analog switch to solve this. I haven't had a chance to test it out, but I can't imagine why it wouldn't work.
  12. David, Not sure if you are still lurking about, but I am back to working on this (though I would love to hear anyone's input). As I dive into the snow machine I want to control, I have a better understanding of how its inner controls work that I need to replicate. Basically, the snow machine will be supplying a constant 12V, when I don't want the snow machine to run, I pass that through. When I want it to run, I need to pass 5V through (which I plan to make via an LDO). What I am going to use to make the distinction is the opto-isolator detecting AC voltage on a section of the disp
  13. I am once again prepping my big homemade Christmas Countdown to go out and am going through the yearly (and then throughout the season) process of replacing bad minis that have blown on it. I switch cut-down strings of minis with 24VAC (10 minis per string). I have a lot of bulbs go out and I think that there is either a voltage spike when changing the numbers (maybe noise on the line too), or an inrush when the numbers change. One of the particularly painful issues is that when the bulb blows, ~80% of the time, the shunt doesn't short it and the whole segment goes down and I have to troubl
  14. I had a similar issue for mine. I ended up making mine out of a PVC toilet flange due to inexpensive cost and its durability compared to other options. Yuo can see some of it here: http://tooz.us/northpolecommandcenter.html
  15. You might want to look at a cam follower (see this animation). I did something similar on a smaller scale using a wiper motor as well to make a bear's walkie talkie go up and down with a pause on both ends using a wiper motor. There are some pics and videos of it here.
