  • KDLaun made the instructable Bubble Machine
    Bubble Machine

    I used the basic design and added a few extra parts. Made a taller mount for the servo, some stabilizing legs for the tank and a mount for the blower our of 2.5mm acrylic. I used a 12v->5v step down module I had for the servo and powered the whole thing with a 12v wall wart power supply. It really cranks out the bubbles.

  • I recently doubled the length of my display stick to 288 pixels. I did get twice the resolution, but I have found, like moggymad1, that the playback is extremely slow, even with the frame delay set at zero. As a result, you have to move VERY slowly, and it's hard to hold the stick steady. I'm seeing a lot of vertical lines in the photos where I didn't with the 144 pixel version. The speed issue may be a limitation of the Mega. I was excited to add more pixels, but right now, I'm inclined to return to my smaller display. Maybe someone can come up with a modernized version with a bit more punch. :-)

  • KDLaun commented on HariFun's instructable Morphing Digital Clock

    I really love my remixremix version of the morphing clock. However, since the change back to DST, the clock displays the wrong time. I thought it would be easy just to adjust the timezone offset and reload the code. Now I'm finding that the very code I uploaded just a couple of months ago will no longer compile in the Arduino IDE and I can't figure out what has changed. No luck re-configuring using double-reset either, as none of the changes seem to take. Any help would be greatly appreciated. I'm getting the following error message:Arduino: 1.8.8 (Windows 7), Board: "NodeMCU 0.9 (ESP-12 Module), 80 MHz, Flash, Disabled, 4M (1M SPIFFS), v2 Lower Memory, Disabled, None, Only Sketch, 115200"MorphingClockRemixRemix-KAT:1312:11: error: expected unqualified-id before '+' token long t…

  • KDLaun made the instructable Arduino Pixel Stick WS2812
    Arduino Pixel Stick WS2812

    I used the same basic parts as the instructable, but laid them out just a bit differently. I used a section of PVC pipe to support the LEDs and ran the power and signal wires inside it. My project used a 1m long 144 LED strip and is powered by a TalentCell12v portable power supply. I was originally going to go with 2m, but decided it was just going to be too long to handle and store.I initially had some trouble getting the code to compile, but eventually found that the Aduino IDE changed the way it handled variable naming in later versions. I put some notes on it in the comments section. Getting the buttons to work was a real pain. I spent a LOT of time on them and must have tried every combination of resistor values several times, but eventually settled on one that seemed to work, althou…

I spent a LOT of time on them and must have tried every combination of resistor values several times, but eventually settled on one that seemed to work, although it was backwards and upside down. I ended up using a hardware solution, flipping my button panel over (and drilling another set of mounting holes) to make it work the way I thought it should. I also had to change the LCD wiring slightly to get the screen contrast to work the way I wanted, adding a 10K pot with the ends attached to 5v and ground and the wiper to the V0 pin on the LCD.

  • I did a little digging, and apparently there's been some changes in the way the compiler handles variable names since the original code was produced. I changed the offending line and it compiled correctly using IDE 1.8.8. Hope that's helpful.const PROGMEM unsigned char gammaTable[] = {

    Did you make a grid to go behind the diffuser?

    Thanks Hari. This was a very easy to follow Instructable. My only issues were in uploading the code to the Amica NodeMCU device I was using. I ended up doing a long-overdue cleanup of my Arduino IDE environment and it flashed without a hitch on the very first try. Going to try the remix version next...

  • Having a PCB is certainly a plus. I've since put together a mini cube and I'm working on a macro version as well.

  • Do you power the multiple panels directly through the Arduino? It seems like large numbers of LEDs might be too much for it.

  • Thanks Doug, very helpful!

  • Nice Instructable! Looks like a good future project. Is there a link somewhere to the InkScape file that someone might use to cut the pieces with a CNC router?

    Thanks, but no luck so far importing PDF, ungrouping and trying to trace.

    Hi Alex,Nice cabinet! It appears your storage boxes might be a bit larger than mine. I measued the metal in the wall angle and it's right at 0.5mm. Despite being thin, it seems quite strong. I'd say it would be able to support a container weighing couple kilos, more if it were attached by more than just the two rivets.

    Yes, you could actually adapt to ANY size or type of pipe depending on your needs. A polished copper version might be kind of cool! I chose the CPVC partly because it seemed a bit stiffer than standard PVC and primarily because the outside diameter was a better fit for the spools I had. Total price for the plastic parts at my local Lowe's was $6.88.

  • Wow! This is an awesome Instructable. I've been toying with various parts of a system like this for a couple of years. This really ties it all together nicely. Can't wait to get started...
