I had a small update on this blog yesterday, but promised a new one today, and here it is. The finished model (except for a spray paint coat to seal up the wood - that comes next).
I am assuming now that the build is gonna be a bit slower the days to come, because I need to figure out a couple of things when it comes to casting the mold. Gotta get hold of release wax too, so I don't think I'm gonna be able to do more with the enclosure before after easter...
Anyway, here's the
:nuke: The enclosure is soon ready for the warp core!
Today, before and after easter dinner party at the in-law's place :yawn: , I killed some time in the workshop. Enclosure model is due to be finished tomorrow - or at least the wood work part of it. Still needs heavy bondo work to be all there, but I am pretty sure I'm starting that tomorrow.
I haz some new pics too of course! :w00t:
First sidewall for the right horn installed. Lots of angles, lots of work.
Today I used up some hours of my day off for enclosure construction!
A couple of pictures of the build so far:
A picture of the front. Didn't have all the right tools, so it was a pain getting everything line up, so some bondo work will be needed to correct everything before making the mold.
Just a quick shot that shows the horns on the front. The angle is gonna be approx. how I hold the "horn".
Hope u like it :)
Until next time, have fun :)
OK, so it isn't a MIDIbox yet, but I intend to add a Jef's sequencer so that it becomes an MB-9090. I pretty much forgot to take any photos during the build as I was too busy soldering. Here are a few pictures of the finished PCBs and their wonderful hideous cardboard base and panel. I intend to design a desktop case for it once I have the sequencer.
Board 1 part finished - the only build photo I took.

EDIT: I deleted the old pics from the blog, and replaced them with lower resolution ones, so it doesn't take ages to load with internet speeds I take for granted :P hihi.
The case build has started! Keep in mind when looking at these pictures: The actual case is going to be cast with fibreglass, and this is only the wood model wich is gonna be used for making a mold. So this is a L O T of work!
I have shot tons of pictures during the work, and some of them mak
Just a short update.
The usians finally came through, and sent me the cloth I ordered a long time ago. This is gonna be used for the front panel. Rest of the case is being cast in plain fibreglass. Colors for the case was originally green / black, but the cloth wich is gonna be cast in transparent epoxy, were not available in green, so it the theme changed to blue / black :).
Thanks to www.compositeenvisions.com for delivering promptly - NOT. Well well, I got it in the end...

Jumper for select PortA Pin0-7 or PortA Pin4-7 + PortB0-3 on DB15 connector. (Future extension ex: old Joystick).
Midi I/O with leds.
Two Audio output with jumper selection, depends on TIA chip.
Finally mounted all the PCBs on one of the 2 more or less identical modulars we're building over at the labs. I made some 2cm (0.787 inches if you prefer mongoloid units of measurement) thick strips of brass. Those were perforated with a 10mm hole so that they can sit between the pots and the front panel, then I added a small hole for the M3 screw that fixes it all in place. 2 strips per card ends up in too much metal shop for my liking but the end result is surprisingly sturdy.
We opted fo
Finally had some time to sit down figure out the cable configuration for J10 / J14 on stereo SID setup. Also made the connectors for audio outs on the sid modules.
There's gonna be some weeks before I get the custom case going, as I am building my future studio at the moment - that has to be done now, as the window for using money on that, and real help came along.
I'm really looking forward to getting started on the case for this. A concept drawing of it is uploaded in my gallery some
Thought I'd try setting up this blog. Get stuff gathered in one place. Until now I have been "blogging" in the gallery. Anyway... I have never ever tought of doing a blog before, so I guess it's gonna be funny to see what comes up here - probably the usual shit :).
url=http://www.ucapps.de/midibox_seq_lite.html]MIDIbox SEQ V4 Lite (in short: MBSEQV4L) is a minimalistic but powerful â€œMIDI sequence looperâ€ which allows to apply various MIDI effects to spice up the original recording. The sequencer never has to be stopped! Even when a new sequence should be entered, loaded or stored from/on a SD Card, MIDI effects are added, etc. It will always run in sync with the internal or externally supplied clock.

This is a demo of a MIDIbox based DIY project that emulates both PROG- and PCM-cards for the Korg Wavestation line of synthesizers. These units were produced in the early 90s. While they are not exactly collectorâ€™s items, the RAM-, ROM-, and PCM-cards for these are very sought after today. The DIY project demoed here aims at replacing a RAM/ROM (PROG) and a PCM (waveform) card with a little MIDIbox-based circuitry and software that allows t
The Television Interface Adaptor(TIA) is the custom chip that is the heart of the Atari 2600
game console, generating the screen display, sound effects, and reading input controller.
Clock and CPU Synchronization:
The 3.58 MHz oscillator (OSC Pin) also clocks a divide by three counter on this chip whose output (1.19 Mhz) is buffered to drive an output pin called 00.
This pin provides the input phase zero clock to the microprocessor which then produces the system 02 clo
I'm probably a bit nostalgic for a time I played the game console in the living room of my parent.
Need electronic sounds that have traumatized my childhood.
The Atari 2600.
I started this project 5 years ago. The first prototype I built was too big and too expensive to manufacture and not programmed into MIOS:
A friend of mine recently reminded me that I had promised to make one for him(another nostalgic).
So I resumed work in late 2010, after checking that no one already did
