dunno if I can help: there are two common types of these sensors I know of: - capacity based (requiring no pressure like the iPod clickWheel) - resistance based (two layers touch at a certain point) pressure based is quite unlikely. the fact that this thing has three connectors might point towards the resistance type. if it's a real Moog Ribbon Controller, it should be resistance based as well, because in german the moog rc is called "Widerstandsband" (Resistance Band). If it has a good size with a good prize ;D, I'd take the risk. Best, Michael

Brilliant! azz- I ought to think of lookup-tables in my first post... Cheers, Michael :)

Hi julienvoirin, to get the BMP is a relatively trivial task; if you're working with a master, the current version of the clockBox is already implementing everything. I did some slave-extensions to the code as well. To generate a square or saw waveform should be no prob: you just have to set up a timer (or use the relevant functions in the clockBox example) and change the form appropriately. Generating a sinus wave in C - however sounds like trouble to me, because (as you surely know), there are no highLevel mathmatical functions on the PIC. So I guess you have to find some ASM-optimized code for this (MB SID? MB FM?). Dunno if something helpful can be found in the lib; but I'm no friend of this lib anyway, because it blows up your code dramatically - and I'm not sure if it's as efficient as it should be. Hope this helps best, Michael

yes indeed: the qt chips are great, they even can be calibrated very easily, just apply a signal to a pin (high or low, don't remember) and touch! should be no problem to use more than one. I used the QT301 (capacitance to analog converter), the datasheet also contains some useful tips about mounting; here's a (probably most useless) video: http://www.audiocommander.de/blog/?p=66 I think I also saw some ICs with multiple inputs in one case and (of course) some with digital output as well.

Yes, these chips are heat-sensitive. Get normal 8-pin sockets, they're just a few cents each. They are quite common, plain 8-pin IC sockets like the one for the optocuppler on the Core: eg at Reichelt: - GS8 for 0,03 EUR (!) - GS8P (golden contacts) for 0,10 EUR Best, Michael

sorry s1, I know it's probably not helpful, but I begin to like tape ;D Check out this nice thing here => http://www.pixelsumo.com/post/tape Cheers, Michael

not a delay project, but definitely analog :) (maybe the walkman stuff is interesting for you...at least it sounds like fun) : http://www.makezine.com/blog/archive/2007/09/end_of_the_weekend_are_yo.html (Making a Mellotron out of Walkmans) best, Michael

no. this is a C++ project that compiles only on Linux/Unix (OSS/Alsa) and Acorn RISC OS. You cannot use C++ for SDCC/MIOS. As the PIC is really just a small device, this requires a really optimized strategy when it comes to buffering stuff... I'm not so sure about the hijacking: if you're talking about a MIDI-recorder that outputs a MIDI file format, I'd say this is quite different from what th0mas is trying to do - (you could have a look at the MIDI Recorder with MMC/SD-Card instead, it's german, but you may translate it with google or babelfish to get the basic stuff) - or if you're just searching for an application to store and replay sequences and do not want to wait for the completion of this project: have you checked out the MBSeq ?

Hello Doctor, interesting topic, this one :) I experimented once with ultrasonic sensors and found them relatively complicated: - they have to be fixed very caryfully and embedded somewhere where no possible vibrations may occur, else there are wrong readings - dunno if the TTL-communication is really "a snap" ??? - to create pulses to trigger the signal and read back those pulses seems quite complicated to me (in terms of digitizing this signal ... but I have no experience in that). IIRC I have seen an ultrasonic I2C device somewhere lately - can't remember where - this would be a bit nicer, I guess... All in all, I found the longest range (1.5 m; effective range ~1m) IR-Distance sensor a bit easier to deal with (so far) - but it's just my 2c, I'd be interested to hear other experiences... Best, Michael

if you mean the forum RSS: I think it's just showing the latest 5 entries... so, not broken, but not really useful either =) Best, Michael

Hi, hehe... it's good to see that some things solve themselve ;D I was away, so I just read your postings. Indeed, I would have suggested a small cap as well, so that the signal is grounded if you don't touch it. If it's not grounded (floating) there are some random values like as you would expect from an unconnected AIN pin. This behaviour is related to the MBHP Hardware concept and not specific to the ACSensorizer program. Best, Michael

I'm currently on the road ;) (back next week...) but afaics the latest css update where I changed the headline-fonts has not been updated by an admin (see page before) What problems besides the gifs and "it's-uglier-than-before" do you have? (btw: anyone is free to convert the pngs to gifs) If you mean the box-sizes: => they are related to the size of your browser window... best, Michael

Speakjet - A PIC ready sound chip?
audiocommander replied to herr_prof's topic in MIDIbox User Projects
that depends on the function: the buttons are mostly triggers/toggles (0/127), but the sliders and pots of course not. After you switched on the device, it should say "READY" once, then when you press the keys on your keyboard (on CH1), you should be able to trigger all allophones and sound FX. When you play on CH2, you'll hear allophones only, on CH3 only FX and on CH11-16 synth sounds. - Or you might change the overall channel (that's the "1" in the display) to change the current sound output to the appropriate mode. If you don't hear nothing at all and cannot change anything, I would expect that your controller isn't connected right? Are your cables connected right? Using an USB keyboard that does not route the output if plugged to the PC? What happens if you use the keyboard that's in MIOSStudio (or any other software keyboard)? Best, Michael Edit: - okay, read your post again: it's a bit cheesy that you can control the harmony-listen but the other stuff is not working ?? - the only explanation I have right now, is that your keyboard is sending on CH5 or 6... can this be? can you set it to CH1? -

audiocommander replied to herr_prof's topic in MIDIbox User Projects
yeah, 2x8 or 2x16; I think I will support both (or 8x2 / 16x2 ;) ) If there will ever be a menu necessary, I might switch to a 2x16 again; (like it's in the sensorizer) though my 2x8 just costed 3 EUR and atm there's all information there that's important, so it's up to you ;) But don't spend more than 10 € or $ on a 2x8...

Hi ultra, good to hear that. I think you should have 0.1.5r1 or 0.1.6; which has been the last 0.1.x version. I uploaded a new version 0.2.6 -> there are no new features compared to 0.2.5, but I compiled it without the HandTracker and AutoPhrase stuff, so it should be nearly the same as 0.1.x, but has some improvements and bugfixes: http://www.audiocommander.de/downloads/midibox/kII_026_070918.tgz (didn't had much time to test it excessively, though, I hope everthing works) If you don't have a 2x8 LCD, you can test it with your 2x16; I can improve the LCD-output if required. In the meanwhile it should work fine also with a 2x16. The 0.2.x version LCD output is a bit less cryptic ;-) You will find a PDF in the subdir "helpers" kII_0.2.4.pdf, which contains an overview of the current (most important) controls for my Korg microKONTROL to help you getting started with all the MIDI controls... you will find all (nearly) all midi controllable functions in the file "IIC_SpeakJetMidiDefines.h".

Speakjet - A PIC ready sound chip?
audiocommander replied to herr_prof's topic in MIDIbox User Projects
Hi Ultra, the normal behaviour would be that it says 1x "READY" once it's powered on and then it awaits your commands. Which kII-version are you using? is it 0.1 or 0.2? If it's 0.2: Have you grounded your AIN-Inputs? If not, I'm not sure wheather you use a beta-version with the HandTracker enabled or not. The easiest way to make sure it has nothing to do with the HandTracker is to clamp your AINs to ground. This is not needed for 0.1. (I will fix this with the next update, but haven't time for this until next week). If it keeps saying ready, this means most probably that the SJ is restarting over and over again - which is most likely a result of a short somewhere or a wrong connection from/to Pin 11 of the SJ (Restart). Is the PIC16 LED on? Don't let your SJ chip be powered on too long before you solved this. It's clear that nothing else is working, when the chip isn't yet connected properly. You should definitely check your board all over again and look for shorts or wrong connections. Does the main app (kII / Core Module) keeps restarting too? (Or other question: are you sure your Core module is okay?) You could also try to power the SJ-board alone and connect it to your PC to see if the serial connections works (I doubt it). The cap on the backside is just to improve the power; it shouldn't have no huge effect if you haven't soldered it. The "other cable" on my photographies goes from PIC16:8 to MAX:12; my board was too small and this way I could use it ;) Best, Michael -

Hi ultra, the J7 pins have to be grounded if not connected. It's all described very well in the datasheet, please have a look. Basically these are I/O pins that either indicate wheather or not something is being spoken or you can use them as digital inputs to control phrase triggering. You might even hook up a RC remote! I haven't used them so far, but it would be a lot harder to add connections if I need them one day, than to just set a jumper to ground an unneeded connection, so it does not hurt to have them... Pins 4 and 6 of the RS232 have to be connected with each other (as the color indicates). The brown RS232 line of the board remains unconnected; it's just brown because I used a colored 5-pin ribbon cable with these colors ;) R4 was indeed a volume pot of the last version, but I removed it because it was quite useless (the SJ is not loud enough anyway) ...forgot to delete it from the list ;D Best, Michael -
looking for smashTV crimp terminals in the UK
audiocommander replied to mat_s's topic in Parts Questions
Hi, Here's the Reichel-Link. Reichelt calls them "PSK-Kontakte" (long live the abbr. noone understands) Though I'm quite sure you'll get those in the UK as well... Best Michael -
Hi and welcome to te forum :) Yes, the 4620 still has the bug, 4685 most probably not, therefor the 4685 might become the new default. Dunno about the others... Best, Michael

oh yeah, the countdown... haven't heard that in the first run... not sure what that is, I doubt it's a speakjet, but you're right it's quite close. Here's the doku of the speech commands: http://developer.apple.com/documentation/UserExperience/Conceptual/ SpeechSynthesisProgrammingGuide/FineTuning/chapter_4_section_3.html The Tune-Format is quite interesting. There's also a very, very, very beautiful application shipped along with the Developer Tools called "Repeat After Me" with which one can easily generate TUNE formats (HOT Tip!!) Cheers, Michael -

hmm, can't see nothing there (no entries, no tracks, no vids). -
Not sure what you're doing exactly stryd, but maybe we should wait until the Admin(s) have updated the css. if you're keen on transparant gifs instead of pngs, you can dl and convert them. We have then to update all sources that use them (from *.png to *.gif) Best, Michael

I haven't changed anything regarding the image positioning, just the fonts and the toc padding.
-
one more thing: I just had a look on NothernLightXes user page and was very happy to see the new features used... :) in contrast, I noticed that Wilba isn't using the headlines as they were supposed to be, I mean starting with h1, then h2, h3 and so on... You started with h1 and then proceed directly to h3 and h4. I think it's quite clear that the fontsize is getting smaller and smaller the lower the heading gets - and moreover the indents are not very continuous. If the TOC is the reason for this, you can disable it completely by typing [tt]~~NOTOC~~[/tt]
