x0xb0x Sequencer LEDs and Switches
(Click for more In Progress (photo gallery retired)<\/em> photos…)<\/center><\/p>\n

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.<\/p>\n

Oh, also, my x0xb0x is mostly<\/em> 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’<\/a>. These need to be fitted, then I need to test everything.<\/p>\n

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

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<\/a>) to get here so that I can test things accurately, and I’m also waiting for a power supply kit (an Elenco XP-720K<\/a>) 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.<\/p>\n

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…<\/p>\n

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)<\/em> thus far, generally marked with their captions from my gallery<\/a>:<\/p>\n

In Progress (photo gallery retired)<\/em>:<\/p>\n

· When replacing a resistor in the power supply with a 200\u2126 one, I accidently melted part of the headphone jack. Whoops.<\/a>
\n· Another detailed shot of the FT232BM, the first SMT part I ever soldered, with a millimeter ruler for comparison.<\/a>
\n· 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.<\/a>
\n· Ahh, that’s better. This is a part of the board after I removed the flux with isopropyl alcohol and a toothbrush.<\/a>
\n· Main panel with everything but a few 2SA733P’s in it. Note the red LEDs.<\/a>
\n· My hacked together panel vise substitute.<\/a>
\n· Everything seems to line up with the front panel…<\/a><\/p><\/blockquote>\n

Parts (photo gallery retired)<\/em>:<\/p>\n

· A pile of the red diffuse LEDs I ordered from Digi-Key.<\/a>
\n· A pile of the water clear red LEDs which came with the x0xb0x.<\/a>
\n· Pile of LEDs in 0.22″ standoffs, ready for installation.<\/a>
\n· A red keycap on one of the tactile switches.<\/a><\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
