A brief update for all of you, in case you were wondering. I’ve been busy with stuff. Blinky stuff.
And yes, the cheap YouTube dubstep is so you don’t hear me saying things like “EFF YEAH”.
So, Caleb ordered 15 five-meter strips of APA102 IP67 sleeved LEDs. APA102’s are relatively new, and straddle the world of addressable LEDs, somewhere between the LPD8806 and the WS2812 in terms of utility and awesomeness. Curiously, they are available only in strips at this point (at least on AliExpress). One little problem with them: Caleb bought IP67 rated strips, which have a silicone sleeve surrounding it. Given the indoor nature of the installation, this sleeving was just going to be a nuisance.
This is part 1 of a ‘however many parts it takes’ series on an LED installation we’re doing for a nightclub on Railroad Square in Santa Rosa. Check out the series.
I freely admit that I have a soft spot for LED lights. Early in 2014 (during the dark months), my maker space had a light painting event, where people brought all manner of lights and long-exposure cameras to play with light in myriad ways. Never mind that it was storming outside. While the rain fell, we all hung out in the dark and played.
Then fellow Chimera hacker/maker/hustler Caleb got a project put together for Google making a gigantic cloud made of steel and lightbulbs, lit from within by color LED lightbulbs. Needless to say, I was crushed. Read the rest of this entry »
I’ll admit, I’m not an avid guitar player. My instrument of choice has always been percussion. Whether it’s slapping my legs to some rhythm in-between my ears or pounding on a djembe or a doumbek or a bodhrán, that’s my first musical love. Heck, I even have an O.G. Roland electronic drum set still sitting in a box after, I don’t know, 9 or 10 years?
Finishing the job
In many ways, this is a continuation (culmination?) of the Randy Destroys Things from last year, when I tore into the Squier Mini Player.Today, I got a bug up my behind, dug out the old amp board, and literally tore it down to the bare PCB. Or as near as matters.
But it wasn’t all for naught: I spent the day also painstakingly tracing all of the circuits on this board to give you (drumroll) a PDF of the schematic, as well as the KiCAD .SCH file (once I figure a good place to host it). Read the rest of this entry »
You’d think it was winter
I’ve come to realize I need to break out a space heater in my workshop in the winter. My knuckles still ache from the cold. And this is Northern California. No wonder I don’t live in New York or Minnesota.
Having just stripped down the printer (i.e. all wires and electronics are pulled, while the motors, extruders, hot end are still in place), it is high time I start figuring out how to rebuild it. A friendly comment from Arthur Wolf of Smoothieboard got me thinking a lot about their electronics package (seeing as I have an affinity for open source hardware and software), which also got me thinking about not only the stepper drivers that we would need, but the power for the heated bed.

Oh. My. God.
You know that feeling. The feeling when you hold a real tool in your hand for the first time.
It has heft. It feels like a tool. Your mind instantly starts to work out all the projects that you can do with it, because it calls out to be used, to be exploited.
It’s winter time everyone, and that must mean that it’s time for Randy to break things and perhaps put them back together. Or perhaps not, only time will tell, friends.
Anyhow, from my friends at Chimera Maker Space I was handed a not-exactly-functioning Bits From Bytes BFB3000 3D printer that was, in the words of Executive Director Dana Woodman, “about to be shitcanned” (NOTE: those were probably not his precise words). My mission, if I chose to accept it was to “make it work.”
Of course, I took this to mean I had unlimited budget and resources. And by that, I mean that whatever I felt like spending on it out of my own pocket to get it running was probably what it would take.
Damn you, Intel Galileo! Why must you vex me with your question, so innocuously posed, in bright yellow letters?
