Has anyone here seen this yet? http://jderogee.tripod.com/project1541.htm. This gizmo presents an SD flash card as up to 512 floppy drives to a Commodore 64 8). Preorders are now closed, but all the info needed to make it are right there on the site. Maybe we can get a group buy of PCBs going. Who's interested?

There's a group buy for Wogglebug #3 module PCBs going on at http://diy.czmok.de/Group-Buys.66.0.html. If you can remember the "music" from the movie Forbidden Planet, that's the kind of sound a Wogglebug can create. Boards are 7.10 Euros each assuming 50 boards are made. Also, there may be a group buy for front panels brewing at the dotcom synth Yahoo group at http://launch.groups.yahoo.com/group/synthesizerscomgroup/.

They're probably so delicate that a gnat farting nearby would cause them to break.

What's the sitrep on the panels?

The switch is the same as is used on the C64. If you can desolder one without making a mess, you can use that. He said something a while ago about ordering some, but I haven't heard anything recently.

Oh... That's right. A transistor protects the output, but not the input. Exactly what is the problem that requires the transistor? Shorting the pins kills the SID?

Ah, I see. I would have used a switch instead.

I've pondered something like this shortly after I saw the beer advert that showed Christmas lights flashing in time with Trans-Siberian Orchestra. I'd start with incandescent lights powered by a couple D-cells. Use DOUT outputs to trip relays to turn on the lights. But, aren't DOUT output lines pulsed? That may cause trouble with the relay. In that case, adding a latch before the relay may be helpful. Would someone who knows more about DOUT please help me out?

Ugh. Even if they were ten times cheaper, it would still be way to expensive.

Why is that guy using shorting plugs? There are jacks that will, when wired correctly, do exactly what he's trying to do.

Jameco is a much better source for that kind of thing. See http://www.jameco.com/

Yow!!! I don't think I'd have the patience to deal with a breadboard like that. If I were you, I'd use telephone punch-down blocks. But still... 20 ranks of pipes in your house. Pardon me whilst I drool. :o

My only problem with PAIA is that the frontpanels are the bad silkscreening. When I got my Fatman, I noticed that tapping the silkscreening with a fingernail would cause it to chip. I tried spraying it with a clear laquer, but that made it look awful and didn't do anything to prevent chipping. So I just scraped off all the silkscreening and labeled things with a Brother labelmaker. It worked out okay since I hacked up the front panel anyhow. FWIW, I moved all the jacks to the rear, cut out the area where the MIDI and CV jacks went, and replaced it with an aluminum plate. There's enough space for a finetune pot and five toggles.

You don't need to use up an entire sheet of transfer paper. First print the pattern on plain paper. Then cut out a piece of transfer paper just large enough for your pattern. Tape that piece over the pattern you printed on the plain paper. Finally, print again on that and you have your trace pattern on the transfer paper. You can find reviews on different papers and various techniques at the Homebrew PCB list at http://groups.yahoo.com/group/Homebrew_PCBs/. For example, certain brands of inkjet photo paper are good for toner-transfer.

1) Take a small microphone and put it in your mouth. 2) Make a really loud belch. 3) Loop the sample, slow it down by a factor of 10 or more. 4) Apply lowpass. I did it with SpiralLoop.

Specifically what bugs you? Is it something that could be fixed without trashing the entire user interface? At present, all I want to do is get rid of the cruft.

Is there anyone here who knows enough about Java to join me in forking Jsynthlib? My intent is to continue development of this utility, fix bugs, add new synths, and generally keep bitrot away. I have a private server to host a CVS repository.

See if you can guess how this was made: http://frotz.homeunix.org/tmp/metalburp-128.ogg

Oops! ;D

Low? I thought the quality was at least decently good.

Try washing the boards, top and bottom, with flux-remover.

See http://frotz.homeunix.org/p112. I'm sold out, but I'm taking names.

It was kinda like that when I did a run of P112 kits. I took preorders for 35 units, but a friend convinced me to make 100. They're all gone now and I'm thinking of doing another run of 100. Is anyone here into old computers?

Perhaps Smash could get in on the deal and add the boards that aren't presold to his inventory.

One more: The silkscreen for the diode in each core has a via right in the middle, obscuring the arrow. Which direction is the arrow pointing?
