Waar haal je die VFD's vandaan als ik vragen mag? Prijs? IK heb zelf tot nu toe een mono SID module gebouwd, via de RS7000 aangestuurd. Ik was ook aan het denken om mn eigen filters te bouwen, maar die nieuwe MFB filterbox is toch ook wel heel interessant ::)

Ik zou wel interesse hebben in VFD displays, Trap.

Great work, and neat interior! I can imagine :)

heeft iemand nog eentje liggen?

Pak de source code van de MIDI merger/monitor als voorbeeld, zo zie je hoe je MIDI kan ontvangen. De rest is vrij simpel: gewoon de ontvangen bytes naar een poort van de PIC kopieren. Als je nog nooit met een PIC gewerkt hebt, probeer dan eerst eens iets simpels zoals het laten knipperen van een ledje ofzo. Ik heb zelf ooit MIDI verstuurd met een PIC. Op het net kan je nog andere projecten vinden die dit ook goed beschrijven. suc6

Great box, and my compliments for the PCB artwork! What do you mean with this? The placement of the componements? trap.

Thanks Thorsten and Wouter!

Ja. Eerst brand je de bootstrap met JMD. Daarna plaats je de pic in de core en kan je m.b.v MIDI-OX MIOS laden (die main.sys dus). Tenslotte moet je nog via MIDI-OX de applicatie laden (volgens mij binnen 2 seconden na powerup van de core), in dit geval dus de midibox sid. Trap.

I could not resist to place this link: http://www.rozzbox.de I think it's such a nice little synth, and all in a 8bit uC! Great retro no-nonsence design. I'm also curious about the parallel digital/analog filter..

As long as we're talking about midi and video: I've been experimenting a while now with video and MIDI. Up to now mostly with hardware, but I want to *generate* more sophisticated video from MIDI as well. I've been looking for a good environment to do simple 3d graphics. I guess it will come down to some hardcore OpenGL programming, or not? Does anybopdy know a good environment? Any tips or links for tutorials? thnx Trap.

Damn, well at least I tried :) Not really AFAIK, but I'll ask somebody who's done this alot. I'm also looking for other techniques to make really detailed and high quality prints for cases. The "SID vicious" print on top is actually a sticker cut out by a cut-plotter, combing several plotted stickers could also be interesting with this etching. AVU stands for Africal Virtual University, apparently this little box was meant for video conferencing in a project to stimulate education in africa. I guess it never got to it, instead it became a SId synth :D

Thnx guys!! And I like yours better Pay_C, wanna trade?? ;) To answer your questions: I did not make this frontpanel! In fact the front panel looked like this when I bought this housing at a dump shop (for only 2 euros ;D). It used to be a satellite demodulater, I just replaced two BNC connectors for 6,3 mm Jacks and voila: it had SID vicious written al over it!! However, I have made some similar panels in the past. Basically it's the same procedure as for making printed circuit boards: you take your blank (aluminium) panel and paint it partly (or completely) with photo laquer. Than you print out your design on overhead sheet or chalk paper and devellop the photo sensitive laquer with UV light. What was black on your print remains. When finished you should protect the panel with blank laquer or folie.. What looks like my MIDI-out on this picture is actually my MIDI-in :) The red LED is DC (power) and the two blue ones are MIDI in and out. I don't have pictures of the inside yet, only one more from a higher angle. To save space on this server I'll put them on my site with some of my other uC projects soon. Trap.

Hi all, For some time now I've been using my mono "SID Vicious" which is just great. However, I do have one problem: when changing a patch I hear a loud 'Plop" sound. Ofcourse this can be expected because all parameters are updated, but the plop is so loud I really have to be carefull :-/ I think it's my combination of SID version (MOS 6581 3984) and capacitors (WIMA 470nF ceramic). Did anyone have this problem before? what's a good combo for SID version and caps for a low plop sound? Thanks, Trap.

Like the song and also a well balanced mix IMO, keep up the good work! trap

Ik zou graag nog een SID willen hebben, liefst een 6581 /R4 maar iets anders is ook ok. Als iemand nog eentje heeft liggen, ik heb nog wel wat spul te ruil van PIC/Atmel. gr, Trap
