Making, baking, and (un-)breaking things in Southeast Michigan.

Tonight I finished assembling x0xb0x #888, but on first power up no audio is heard. The sequencer runs and I know the VCO works, but beyond that I’m not sure where the problem lies. Time to dig through the schematic while sitting in front of it with a scope.
Fun.
(I just hope I don’t have a blown BA6110 like some folks have had…)

A few days back I released my x0xb0x artwork into Creative Commons, but I didn’t mention what it was that got me thinking about the artwork and its license, prompting me to do this. It turns out that James Irwin was wanting to print more copies of this artwork up to sell via his shop AbleIdeas. Wanting the art available for others I licensed the art as I did, giving him permission to print and sell copies, and he agreed to send me one piece.
I received this piece of x0xb0x art today, and I must say that it looks pretty good. The texture of the plastic on the top layer is a bit more matte than my original pieces from Maverick Label, but the print quality and the cutting looks great. Lining one of his pieces up with mine showed them to be practically identical. The adhesive backing is the slightly thicker 3M 468 MP, which is 5 mil as opposed to the 2 mil 467 MP I’d selected from Maverick. This will adhere better to rough surfaces, but supposedly doesn’t help with the bond on smooth surfaces. I’ve been told that this adhesive will change to the 467 MP in future runs.
Oh, and (possibly) best of all? The Thailand Post (ไปรษณีย์ไทย) envelope the artwork came in was exceedingly cute (front · back). It could have used some backing board to ensure the artwork didn’t get bent (as the slight wrinkles visible here on the backing paper allude to), but the plastic looked just fine. I’ve mentioned this to James and he’s made note of it.
So, if you’re wanting some of my artwork printed up for your x0xb0x and don’t want to order in quantity from Maverick Label, definitely check out AbleIdeas x0xb0x store.
In x0xb0x #888 building news, tonight I sanded down the front panel to remove the epoxy lettering, cut a hole in the rear panel for the power switch, fashioned an impromptu indoor painting area, then began painting the rear panel. Hopefully I’m only a few days away from applying this artwork and finishing off another x0xb0x. I do still have to order some knobs and pushbuttons from Digi-Key, but those are essentially only finishing touches. Those can be changed after the case is closed.

After sleeping in a bit, most of today was spent on the mainboard for x0xb0x #888. Everything went quite well, the board cleaned up great, and it’s ready to hook up in the case. I even made a particular point of soldering all sealed components before washing, then doing electro-mechanical parts afterward with no-clean flux. I haven’t always been this particular in the past, and having to occasionally avoid a switch or button while scrubbing the flux off was a hassle.
Tomorrow I’m hoping to start on painting the back panel, possibly adding a power switch, and assembling everything for its first full-system test and (hopefully) tuning. I’ve already confirmed functionality of the power supply and USB (which the FT232BM from yesterday handles), so that’s a good start.
Here’s two more photos from today’s work:
· Soldered connections for the tactile switches, showing the slight bit of residue from no-clean flux.

· Detail of the cleaned solder joints on the DAC, located between the mode and bank switches.

Yesterday while washing dishes someone was walking around my neighborhood putting Benefiber recipe booklets in people’s front door handles. Living in an area with mostly older / retired people I must get roped into the demographic of those who buy fiber supplements.
While I like ensuring that my diet has sufficient amounts of fiber in it, I do so by eating things like porridge instead of bizarre concoctions like the Fiberccino shown above. Water (capitalized, for some reason) is the most natural thing in there, with refined sugar as the distant second.
Other recipes in this booklet include Upside-Down Pizza, Quick Sloppy Joes, Cajun Chicken Salad, Cheesecake Pie, Apple Dumplings, and Raspberry Sauce, all with Benefiber-brand wheat dextrin, because Benefiber® Makes Taking Fiber Easier Perverse™.

Either I’ve become a bit better at soldering, or things like the FT232BM in the x0xb0x are easier than I recall. I’ve finished the IO board so it’s time to wash and test it, then move on to the main PCB.
Here’s an amusing (to me) photo of solder dust from below the brass pad in the iron stand. Note the black cable tie at the top for scale.
Oh, also, this assembly is once again reminding me of my very dislike for cornrowed (upended) resistors. They take 3x as long to fit as normal, flat ones. Also, when there are 50 of one value of resistor right next to each other, maybe resistor networks would be a good idea?
UPDATE: Here’s the same chip, with most of the flux removed. There is still a very small residual amount of non-water-soluble flux left, which was removed after this picture was taken.

The morning after the giant storm which dropped almost a foot of snow here it’s nice and bright and sunny. Hopefully the roads are becoming clear and it’ll stay cold enough that this turns into a nice blanket of winter sitting over everything for the rest of the holidays.
Of course, then right after that it’ll turn into typically Michigan piles of gray and brown dirty snow piled at the sides of parking lots, mixed with shopping carts, Burger King bags, and broken pieces of parking blocks.
(This photo was taken in the reflection from the microwave in the kitchen.)

After the snowing stopped (about 3pm) I decided that I should try going for a bike ride. This was much more difficult than I expected, and I wasn’t able to ride more than about 100′. As soon as I’d get going the front wheel would slide and essentially turn into a ski, and I’d slow down enough that I’d have to stop.
It seems the only thing that this much snow is good for is holding up my bike while I take a picture of it fitted with its new fenders. The rear one is a little low, but that’s roughly how it’ll be adjusted.
This weather is making me wish I had access to a Pugsly, but I also don’t want to spend the $1500 or so it’ll take to build one up nicely. I think I’ll just wait until a bit of the snow goes away.

For those of you not in the midwest, this is the reason I’m staying home today. Also, this was taken about 45 minutes ago (yes, it seems the time in my camera is wrong), and we’re only about half way through the storm.
While I was writing this the power flickered, went out for about 30 seconds, then came back on. While I would still have had hot water and the ability to cook food, I would have been without heat had the power stayed out, so those 30 seconds were a bit nerve wracking.
Looking outside, my footprints from when I went out to take that photo have pretty much been obscured and now just look like slight dents in the ground.
For reference purposes I’ll quote the National Weather Service‘s warnings for today. One of them even notes that there may be thundersnow. There is no snow more hardcore than THUNDERSNOW. \m/

Today I purchased some extra dorky fenders for my mountain bike. I don’t really mind mud, but I don’t like glops on my face and a handful rubbed into my back when riding in cold, sloppy weather. This is exactly the kind of weather we will have here in Michigan on off-road paths through March or April.
They look a bit strange on the bike, but seem like they’ll do a good job of collecting / blocking spray and mud. I’ll try and get a photo of them mounted after I try them out in actual riding.
For reference, the fenders I picked up are the SKS X-TRA-DRY rear and SHOCKBOARD front mudguard.

Almost three years ago (wow!) I built my first x0xb0x. Being unhappy with the original artwork I designed my own, making the template available for others to use. However, I’d never actually released the artwork under a particular license. I’d forgotten about this until recently, so now I’d like to release this artwork under the Creative Commons Attribution 3.0 license.
This means that anyone can reuse this template and artwork, sell artwork based on this, and do anything they want with it as long as they credit my contribution.
Here are links to the various template files which I am releasing under this license:
