Wow, I've been Blogged at Make Zine. Kick ass!

As promised here are: Musics, Photos, Damages and Reflections.

In the beginning...	Filing down pots after cutting	Number 28 = 23 + 5!	Cataloging EVERYTHING
First time soldering something to the board	IO board when we got it. (USB pre-soldered)	First Milestone of IO/Power	My beautiful wife, the solder queen!
The VCO section is finished!	Power attached for testing.	Transistorize teh world!	Waveform Switch! First Knob!
VCF (ohhh!) VCA (ohhh!) and Mixer	VCO and Envelope	KNOBS! SWITCHES!	Almost done...
IO Board finished!	Testing the whole unit	Hmm, more 'testing' required.	Funky zoom on topside of board.
Finished! Mmmmmm. X Ohhhhh Sex Box!

Damage Done To Humans By x0xb0x

• Poked a LED through my thumb mounting it on the standoff
• Very minor soldering iron burn on my middle finger
• Lung Damage due to burning flux and solder
• Sleep Deprivation
• Sanity damage due to anticipation
• Anticipated: Ear damage

Damage Done to x0xb0x By Humans

• One 6V Voltage Regulator. Totally fuct. No hope for patient. Currently sitting on the floor behind our computers, sans its three legs.
• One transistor slightly wounded from soldering, cutting, and re soldering. Patient made full recovery.
• Amputated Headphone Jack

Testing the x0xb0x.

After the filter section, we opted to do no further testing until we had the thing completed. For better or worse. In retrospect, I would have liked to have done more frequent testing. Not having a desktop power supply really put a stumbling block in our testing. Using 2 double-a batteries connected together did work enough to do some very VERY basic testing, but certainly no calibration. Not having a scope meant that I had to use a pair of headphones for the testing. This sucks, because you can hardly hear the notes, and it doesn't sound ANYTHING like a TB-303 at this stage in testing, so deep inside the back of my head, there was a little voice that said "That sounds nothing like it. You've paid a bunch of money for something that makes thin, weedy noises, and they aren't even loud, and it might not even work when you have it all put together!".

I found the envelope testing to be hard to follow, so we decided to skip that until we could properly generate envelopes in keyboard mode. By that time, we were so close anyway, that we got the rest of it all put together.

Except... it didn't work. Until we put the microcontroller in. You know.. the brains. Duh. I coulda used some. I blame lack of sleep (it was almost 2:30 at that point), and flux inhalation. So we did get it working, and I twisted knobs on random mode.

Calibration of the x0xb0x.

Calibration of the box went surprisingly smooth. I did have some troubles with the software oscilloscope crashing, but it wasn't that big a deal. I used this one Here

I have the resonant frequency tuned (roughly) to the official roland specification of 500 Hz. Because I did the tuning after the envelope and Accent sections, I am probably off some, but if I am, it just means I have a higher resonance, which will hopefully account for the slight difference in square waves between the x0xb0x and tb303.
