A load of fun, whether or not you're a musician - The Top 20 Synths of All Time, caught by rabitguy. (Actually, only positions 18-20 in the first part) Audio joy galore! Available in Flash, QuickTime, and WMV versions.

I think I must obtain this. A Kama Citra poster, starring a host of extraordinarily flexible citras. ("Note: Adam Wan and Sofawolf Press make no claim as to the applicability of the Citra techniques presented herein to the human form, and are not responsible for any injuries suffered in attempts to replicate them. However Adam Wan accepts full credit for any you actually manage to master.")

Or, for those on a more restricting budget, maybe just print a copy of this week's VG Cats out. =:D (So that's what a "donkey punch" is.. its application to Enron seems delightfully apt)

Seen by ysengrin by the De Young museum, "Child with Giant Hare" by Arthur Putnam.
Now this looks like a pretty cool projector. Only suitable for darkened rooms, at 25 lumens, but that said, it's palm-sized, weighs one pound, has native SVGA resolution, and is lit by an LED module rated for 10,000 hours, for $380. Perfect for guerilla cinema - just open up the laptop and start showing shorts in the street. =:D

Want to know what a Boltzmann Brain is? (Best read after the first caffeine of the day. Or other psychoactives =:)

Dragon Riding for Beginners

And Bob Bassett's latest is well worth a look. Never has ultimate evil been so utterly adorable. ^_^

Quite a fun look back at the Lisa, in the form of a Lisa emulator, available for OS X and Windows. "Another thing you'll notice about Lisa is that there is no Quit option. You can set everything aside, set the document you are working on aside, Save and Continue, and Save and Put Away, but you can't Quit. The reason you can't quit is because all of the programs are always open. The LOS is totally document oriented."

"The Rev. Lonnie W. Latham had supported a resolution calling on gays and lesbians to reject their "sinful, destructive lifestyle" before his Jan. 3, 2006, arrest outside the Habana Inn in Oklahoma City. Authorities say he asked the undercover policeman to come up to his hotel for oral sex." Reminds me, we never did get an answer as to just why Jeff Gannon had visited the White House quite so frequently, and at such interesting hours.

Hee! The poll results from the previous entry are looking quite amusing in places. I must give off some interestingly mixed signals.. =:D

And thanks to andy_squirrel for pointing out there's a third - and definitely the best so far, despite the absence of frolicking bunnies - trailer for the Simpsons movie over here. Speaking of which, the trailer for the ATHF movie is also now up, with a beautifully cheesy fantasy-style poster. (.. and what's Neil Peart doing in there?)

Sitting in my basement, sad and alone and slightly corroded from old water damage when our apartment ceiling exploded, is a Roland D5 Linear synth. It's not the biggest and brightest of it's generation - lowliest of the D series, surpassed by the D10 and D20. But it was bloopy and a well-loved keyboard while it was operational.

It took a face-plant once during operation, and stopped putting out sound shortly thereafter, not necessarily relatedly. There's a problem, if I recall - it's been a while - with the board's power, the negative voltage trace was shorted out and the on-board rectifiers kept torching itself. Shipped it to Roland for repairs, they shipped it back and said they couldn't fix it.

I have a plan. An evil, silly plan. It involves restructuring the board from a flat monolithic block to something shaped more like a Minimoog, giving me ample room to do repairs to the inner structure without having to tear it all apart when I'm working on it (the inside of the keyboard has a long main board and an equally long duaghterboard with the display and keypads and such).. and then, then there's be room to do a little circuit bending, install some pots and sliders..

I'm never going to live long enough to get all my plans done, am I? :(
Shorted trace, huh? If you can't unshort it, I bet it'd work to cut the trace on both sides of the short and run a jumper wire across the cut-out section, just find the solder points closest to each side of the cut-out area and attach the jumper wire to them... Least, that's what I'd probably try...
Ah, but finding the short's going to be the tricky part. :)

That said, you're right. I have a vague plan of tracing back through the power supply part of the mainboard until I've got the discrete traces for the various voltages I need - thankfully there are some test points on the board with silkscreened indications of what kind of power I should find where. I seem to recall a few different positives and one negative, probably for opamps. Then I'll make an appropriate well-filtered supply or three to provide it the power it needs, sever the connections to the on-board power, and splice the new supply in place.

In my copious spare time. ;)
Replacing the whole power section? Sounds complicated. My approach would simply bypass the damage and keep the basic circuit the same. Guess I just take a different approach to things, huh. :)

But yes, finding the short would seem to be the hard part...
