Well, the laser guitar is on display there, though to my dismay is not out in the open for people to play around with. I told them repeatedly they could leave it out, but I guess they're worried...

Hey, everyone! I thought you'd all like to know that my laser guitar will be on display at my local museum for an exhibition called RAM. It's a showcase for art meeting technology. A few of my...

The input mechanism, mostly. The best I can think of right now is that the player can kinda wiggle their finger lengthwise within the confines of two frets to simulate the effect. The problem is...

I got a basic "whammy bar" working last night, I'll improve it tonight so that it's more responsive. I still have to figure out the best way to simulate a "string bend" on strings that don't...

OK! Kids in bed, time to start working this new shiny code into my guitar... After I watch Eureka. ;)

Sweeeet. The final piece in my plan for world domination! Ok, well, maybe I'll settle for laser guitar awesomeness.

Thanks, Jonathan! You are a gentleman and a scholar.

I'd look at the hardware, but you said it's the same on three different boards. Very odd indeed. Does DAC.start work with pin 11, by any chance? Does anything work with pin 11 (can you blink an...

Dunno if it helps, but did you know that you can share Data I/O and clock pins between the ADCs? The only thing that needs to be unique is the CS pin. Of course, you need to make sure that only the...

Thanks for the links, everyone! I'm sure I'll find what I need here!

Hi everyone,

I'm thinking of starting up a project that would randomly fade up to 25 LEDs on and off, like stars or fireflies. I'm sure you know what I mean. Since the propeller wouldn't really...

BST (Brad's Spin Tool) allows you to set multiple object directories. You also set the order in which those directories are searched.

Wow, amazing work. I've got nothing more to add, other than that I'm looking forward to using it once it's finished!

Ooooh, you just gave me an AWESOME idea! ;)

Should work fine. You can save yourself some cost and board space by combining C2 and C3 into a single capacitor. 220uF should be plenty.

How broken is the connector? If you've torn off pads then you may be stuck. But if the connector itself is the only thing that's broken, then you should be able to replace it. I'm pretty sure this...

It's been a while but I thought I'd update everyone on the progress I've made with my Karplus-Strong wielding laser guitar.

First off, I fixed the memory issues I was having, both in running out...

The best way would be to use a separate 24V power supply for the solenoids. Each solenoid would be switched on and off by a suitably sized MOSFET. You can get logic-level MOSFETS, which can be...

Some tips:

1. Keep the AC stuff on one side of the enclosure, and DC stuff on the other. Try not to have AC power lines crossing DC or signal lines.
2. How you attach grounds/VSS/-V will...

Do the Plant Whisperer and my upcoming laser guitar count as supported platforms? LOL.

Ah, I thought you'd seen those already and wanted more. ;)

Yep, there are bits of knowledge here and there, but there is not a full, detailed workbook. In addition to the resources you'll find here and at the 12blocks website, there are a few Instructables...

That's one of many current and past CNC projects on Kickstarter. Do a search for "CNC" and they'll all turn up.

Are you trying to solve the issue of price or portability? If it's an issue of price, see if you can find a good used full-size laptop. Even an old WinXP unit will have plenty of power for...

Sounds like an entirely new chip design, which they're doing already. I think you're just going to have to wait until the Prop II arrives.

Exactly. An internal ground and power layer will actually work together as a big, flat capacitor; further enhancing the decoupling capability of the PCB. A two layer board would certainly be...
