x0xb0x Sequencer LEDs and Switches

x0xb0x Sequencer LEDs and Switches
(Click for more In Progress (photo gallery retired) photos…)

Have I mentioned that I love that macro lens? With the 1:1 extender it’s so, so, so much fun to play with… I only wish I had increased the depth of field there so that focus didn’t fall off so quickly. Still, I like it.

Oh, also, my x0xb0x is mostly done. I say mostly because I’m still waiting for Monday’s delivery of a Mouser order containing a bunch of 2SA733P transistors. The reason is detailed here under the section labeled ‘Picking the right transistors’. These need to be fitted, then I need to test everything.

Somewhere in there I also have to order up the front panel overlays (photo gallery retired), too… I just hope other people want to buy them.

The testing stuff brings up something else. First, I’m worried that my x0xb0x will have some sort of problem. Second, I’m still waiting for a new DMM (a Fluke 179/EDA Kit) to get here so that I can test things accurately, and I’m also waiting for a power supply kit (an Elenco XP-720K) so that I can feed power to various bits of the synth while I’m testing it. After I build the power supply, of course.

So, to make a long story short, I’ve gotten things about as far as they can go for now. I’ll do more later…

In case you are interested, here’s some of the somewhat more notable photos that I’ve taken of the my x0xb0x building (photo gallery retired) thus far, generally marked with their captions from my gallery:

In Progress (photo gallery retired):

· When replacing a resistor in the power supply with a 200Ω one, I accidently melted part of the headphone jack. Whoops.
· Another detailed shot of the FT232BM, the first SMT part I ever soldered, with a millimeter ruler for comparison.
· While soldering, flux is left behind on the PCB. This must be cleaned off afterwards. The flux can be seen here as clearish blobs over the solder.
· Ahh, that’s better. This is a part of the board after I removed the flux with isopropyl alcohol and a toothbrush.
· Main panel with everything but a few 2SA733P’s in it. Note the red LEDs.
· My hacked together panel vise substitute.
· Everything seems to line up with the front panel…

Parts (photo gallery retired):

· A pile of the red diffuse LEDs I ordered from Digi-Key.
· A pile of the water clear red LEDs which came with the x0xb0x.
· Pile of LEDs in 0.22″ standoffs, ready for installation.
· A red keycap on one of the tactile switches.
