Due to the impacts of the coronavirus outbreak, we are experiencing longer than normal lead times on certain products. We encourage back-ordering out-of-stock items to receive them as soon as possible.

  • I found a really great use for these. Possibly... the best use??? http://youtu.be/f9CN5YiTgSI

  • How practical would it be to use this to detect smoke (like, as part of a fire protection system)? The datasheet recommends that I don't use it for this, but do they mean that in a "this device is incapable of detecting smoke from a fire" way, or in a "don't let your life depend on this device" way?

  • These lights use a protocol more similar to SPI than I2C. They're basically shift registers, only instead of 24 outputs, you need to shift out three bytes of eight bits each, each byte representing the brightness of green, red, and blue (or is it RGB? I forget). Just like regular shift registers, any bytes beyond what a single register can handle will be passed on to the next light in the chain.

  • Retired? Why is it retired? I was just about to buy a handful of these! I'd check out the other Arduino development tools, except that none of them resemble this product at all. Will you be selling the Arduino Ethernet soon? (I'd still prefer this product; I hate those stupid sockets.)

  • How do I assemble a complete package for this thing? Is it this LED breakout, the driver board, a lens, and a heat sink?

  • I've been playing with this thing for about an hour. I absolutely love the tiny form factor. What I don't like is that it's very, um... slow. It takes eight seconds to draw a fullscreen (400x240) GIF or BMP, and 15 seconds for a JPG. Drawing text, a group of buttons, or round shapes (arc, circle, etc.) takes a little while; you can sit there and watch the pixels draw onto the screen.

    If I were just designing for myself, maybe I could put up with the sluggishness, but I'm trying to envision myself as an end user. No matter how well-designed the interface itself was, would the end-user put up with a screen that took several seconds to render each time you made a choice? That makes for poor feedback.

    Am I just doing something wrong, or is this simply a hardware limitation? Can any optimization be done? Would I get better results with a higher-end EZLCD product?

  • Holy crap! Well, it's too late for Christmas this year, but it looks like next year will be even more merry than this one.

  • "When I first looked at the LED strips, I wanted to resist the temptation to use them as Christmas lights as much as possible."

    Why would you resist that temptation?? It's a great temptation!

  • It might seem a little pricey, but it's an order of magnitude more affordable than touchscreen panels from AMX or Crestron, which is more-or-less what I'm trying to imitate. You can do a lot more with those interfaces, of course, but I can't get over the feeling that they're significantly marked up in price.

  • I'd like to mount this panel in a single-gang box using a custom plate I could whip up on my CNC machine. The tricky part is that I'd like it to have a portrait orientation. Is there a way in software to flip everything 90 degrees? At minimum, I'd need to be able to rotate text and widgets.

No public wish lists :(
