This page contains some research related pictures not all available on other pages. Jan 3, 2001: Updated picture links
(NOTE: the rest of this page is not so recent anymore)
Sorry its a bit later, but now a page with a complete modest PA system ('home'-built) is available, plus pictures of the available synth parts and the 19 inch rack mountable prototype enclosure.
I'll make a picture of the assembled system (which already has withstood 2 parties), and I've made a page on the Z80 system I've mentioned on my other pages, but unfortunately I couldn't yet ftp the pictures in place, because I'm out of wen space on tripod. be sure to check later though (I'll redirect them elsewhere) because it also contains neat pictures of the almost 20 year old DMA LED display unit I mentioned !
Though 80 Watts is fine, and the applied chip satisfactory, the availability of the Spice circuit simulator stirrs my curiosity as to what may be achieved through some serious discrete electronics design, and what the characteristics of some amplifier circuits can be. I will gather up some of my findings . I'll also include my notes on how to extend the set of available circuit models in Microsims demo package. When I'm rich I'll buy the thing (no promise, its quite expensive, but I'll consider it seriously)..
I've added a server option in a mesa program, be sure to check the bottom of the above page ! Sources, executables (windows 95) and libraries available.
I've done a prototype of a combination of a 'talk' tool, and a remote file transfer tool, check out the version 0.3 for free !
Stay tuned for updates om the synth front, for instance I've started to look at some of the blocks of the fatman synth, which has some interestingly to the point implementations of analog synth building blocks in it. Worth reinstalling microsim's simulator (the evaluation version, that is) for. Sp are the schematics from here.
I've been working with MicrSim, and found out that before the demo-limits are reached, serious designs are possible. Therefore, the current project is to desig and simulate a microprocessor core , and a custom DSP core for various electronic music tasks.
Here is an example of a drum track generator I've started to program, with example sound file. NEW: I've made the drum track generator available as a stand alone Bwise application with (C) program. Build your own drum tracks!! This points directly to the ZIP file conaining all necesary parts, check above drum page for a description.
I've picked up on Tcl/tk, a package I;ve started a block diagram editor in when I was still at university, and that I've done a complete UI in for a graphics package and a set of communication programs. Lets see what a few days work in Tcl/Tk can do. In fact that page now contains a graphical 'flow' type of editor, which I programmed in about a day and a half (try that in Java or C++..).
Also try the Tclet (embedded tcl/tk in a hml page) version of Bwise on the same page!
Making printed circuit boards also appears to be no problem, Microsims autorouter works just fine on the circuits in the schematic editor. I'll need to learn some of the PCB lingo, but the results seem good enough to be put into a board, and they use standard file formats. I tried others, but here is a very small inverting amplifier unit in schematics and half hand placed, auto routed circuit board:
A page in progress is the sampler page , where I build up towards the circuitry for a serious sound sampler.
To play around with the PM synthesis program, download the file
pm.exe, start a DOS shell, and type for instance:
pm 128 10000 soundfile sound.wav outnode 40
The program takes some time to run, when it is finished
use a WAV player to listen to the ressults, usually clicking
on the 'sound.wav' file in windows will do the trick. I am
not sure the WAV format is perfect yet, some programs seemed not
to be able to process it, but I could play the 16 bit PCM file
simply by using the windows 'property' menu on the wav file.
Experiment with the number of nodes (128, e.g. 64) and the sample length (10000, could also be 100000 for longer samples) and the place of the waveguide where the virtual microphone is placed (40 can be anythin between 1 and the number of nodes-1). Better still, change the source code and recompile! Or wait for more elaborate user interfaces to appear on this site...
An outline of my synthesizer related past activities, and a whole lot of synthesizer building blocks, toghether good for at least a few synth designs.
Various electronics based (product) ideas.
Main electrical engineering page contains various references.
I've glanced at and programmed a fairly in depth Java example for which I had at least one motivation .
Cygwin has been my second solution to not having a decent compiler and no money to purchase one (gnu of course the first), and adds a lot of UNIX-like facilities.
There are various subjects I haven't by far written enough about, such as various ideas in computer software and architecture and hardware , in nano-biology and in neuro(no)logy . See also this older link .
I've made various CV pages and docs for various purposes, this is a (recent) short one, this a more elaborate one to a synthesizer company. I'll add more later.
Can one publish to expose possible criminal behaviour? I think one should, and start with an attempt to verify wether some of my thoughts are somehow related to reality. Read the heading of this page very well. Let me in on your thoughts, sign the questbook (can be done anonymously), send me a mail, talk to me (the picture on the main page needs to be processed to include a beard, because my raisor has been stolen).
What is christianity about? This FAQ answers some profound questions, while here a few experiences with christianity are presented as a consumer guide.
A lot of materials that grew during my study of the hebrew and greek of the old and new testament are long but not hollow texts, such as on imagery in James, where do I stand on main issues from e.g. Corintians (quite challenging), maltranslations of the greek (idem !), and my general (old) translation page which contains pointers to various translation efforts, amoung others a pictorial interpretation of the hebrew alphabeth , and its verification in (old) hebrew word examples. All of this can be put next to a examle interlinear translation to find out how much difference there can be between letter and lexicon based translation (and interlinear example) , and our bible text.
The greek has similar phenomenons, such as very crucial words like virgins .
Also, quite some passages have been translated/interpreted wrongly, such as in Timoty .
