Did I mention ADD? and anything to do with water, drip irrigation systems and chasing verbal rabits.

  • I am not sure what type of fertilizer you can use with fish, but I would say by the yellowing of the leaves of what looks like bok choy, you need something. I know they do make plant food for fish tanks. I would say either your magnesium is low or your iron. I use to run a 240 gallon fish tank and a number of other tanks, plus, a short 30 gallon guppy tank with lots of plants.

  • Q: about the Arduino IDE – has anyone figured out why the SamD boards are grayed out under Tools\boards in the 1.6.6 ? Adafruit had some answers about problem libraries, but not sure if it addresses this issue. Wish Nate had someone who was in charge of software issues.

  • I wish this could be I2C using PCA9555 for decoding the keys (also handles the Debouncing of said keys, and you don’t have to worry about polling), and four PCA9635 to run the RGB leds (you may need to do some hardware tap dancing to drive the LEDs meaning extra resistor and a transistor, also you might need a different RGB led - but I can see why it could not be used). The cool thing is the whole thing becomes 5 wires to run the board- +5V, GND, SCL, SDA, and a INT. The INT is what lets you NOT have to Poll all the switches. When a key is pressed, the INT lets the micro-controller know something happen, then the Micro Controller checks the two ports to see which key has been pressed on the PCA9555. It cuts down on wasting time polling each key, and handles all the timing for the LEDs (which also means you can get the full spectrum of color from your LEDs). Everybody makes out that the coding is hard for the I2C but it really isn’t.

  • Don’t say that too out loud— someone will do it.

  • RE: Dentures/Retainers — they are already doing that. The COOL thing about this idea is when they now make the mold of your mouth, they can scan the mold (Which means you don’t have to have a new mold of your mouth every time they want to do something- the old way destroyed the mold so you had to have a new one every time), then make the Dentures/Retainer/whatever. You lose your Dentures, retainer, whatever, they can make a new one without the hassle which means quick turn around.

  • It would be interesting if there was a way to 3-D Print sand castings. Then you could make your own castings of something and then actually pour metal into the casting. I am thinking something like making a actual working turbocharger or something like that. Yeah plastic is nice, but it does not always hold up to the heat for some projects. (Yeah, you would have to do some tooling on your project, but this would bring you one step closer to having a working project.) I am almost thinking something like what you make for ballast for model railroad track- a mixture of sand, dish soap, glue, and water. Problem would be how to get it to dry quickly, and be put through a small nozzle. Yeah you would have to have one of those box sand blasters to clear the sand castings, but that would still be a lot quicker.

  • But is the stencil printer PB&J friendly?

  • I am sure glad Wedge did not add anything to the table.

  • Q: of the three types of filaments which has the best resistance to UV?

  • The only way to get rid of an earworm at Sparkfun.

No public wish lists :(
