Raspberry Pi 2 and Other Stuff

Got back from a 10 day survey in the Aegean Sea last Thursday. I think, It’s been a long time since the last time I posted something here. So, here we go.

Before the trip, about 2 weeks ago, my brother and I purchased two Raspberry Pi 2’s, and a Radxa Rock Pro (not going to use all of’em at once) for a future art project of his. I also got acrylic housings and a NoIR Camera for the Rpi 2’s. I’ve been playing around with the Raspberry Pi 2 (as Radxa Rock Pro waits for its turn), and I totally love it.

Ryokan

One of my favorite Zen stories… I’m not sure if this could be considered a Koan…

Kodo Sawaki

Japanese Zen Monk, Kodo Sawaki

Ryokan, a Zen master, lived the simplest kind of life in a little hut at the foot of a mountain. One evening a thief visited the hut only to discover there was nothing to steal.

Ryokan returned and caught him. “You have come a long way to visit me,” he told the prowler, “and you should not return empty-handed. Please take my clothes as a gift.”

The thief was bewildered. He took the clothes and slunk away.

Ryoken sat naked, watching the moon. “Poor fellow,” he mused, “I wish I could have given him this beautiful moon.”

NTN – 600 Hull Rigging – Part XXI

Yesterday, I messed up the front plate. I had drawn the whole thing in SketchUp, and cut and drilled (one wrong hole, fixed with epoxy putty) the aluminum front plate for the motor bolts couple of days ago.

I will drill the front holes on the side brackets such that, when they’re placed among the wooden rails in the hull, they’ll be right in the middle of the slots cut in the front plate, allowing for 3.8 mm motion to each side.

I will start working on the new front plate, soon.

Recommended Firefox Plugin – Open in Browser 1.5

If your Firefox fails to open text files, such as C code, as text files, this plug-in is pretty handy.

Open in Browser 1.15

Open MenuNo more waiting for some IDE or text editor to open on-line codes or other annoying stuff.

I normally use GKrellM plug-in GkrellShoot to get screenshots on my Awesome WM, and it uses ImageMagic to grab the screen. I didn’t know it could not grab open menus (and I was too lazy to find a way to do it with it), so I moved on to GIMP (File -> Create -> Screenshot), which did a great job.

NTN – 600 Hull Rigging – Part XX

I started working on the boat again, after a long break. After squaring my wise again, and also squaring the bottom of the rotary table, I’m back to working on the mill. I placed them both, side by side, on the table this time. Since the table can handle 55 kg, I think it’ll be fine. The weigh about 35 kg, including the 3-jaw chuck (which I need to center on the rotary table, using a piece my friend Murat is making for me on his lathe).

Last weekend, I got some metal parts (I didn’t even look to see what they were) from a hardware store, which seemed suitable for the motor side brackets. They were thick and tough, yet light. So, I got about 5 of them.

Rotary Table and Electronic Controller

Ok, it’s been a while. We are in a new year, (sarcastic) yaaaay. But at least we have a 4 (minus 2 already) day break ’til Monday, yet I don’t feel very productive. I still did a couple of things in the shop, in the past week.

I worked on the aforementioned rotary table controller, played with the rotary table and the 125 mm manufacturing chuck I got for it, and I still need to finish the boat! It snowed a bit lately, and we’re expecting more. I want more…
