Yup, Â illogik is absolutely right ;) You generate +/-15VAC, by connecting secondary windings in series (the ends will give that 30VAC) and "central tap" (those pins connected together) is a reference ground, or 0V. bye, Moebius p.s. I found ICL3038 from a trashed CT (roentgen) machine laying in the backjard of a hospital. Man, You should have seen "the quality" of the "scan motor control" PCB - I hope it wasn't tested on living subjects as backside of the board had 'bout dozen jumperwires in it. ;)

Well, Nice story. It gives some good tips on low level FM programming. But it's a bit annoying, that he keeps repeating an incorrect information about Sega Genesis having the same soundchip as Yamaha TX81z ;) Bye, Moebius

Hi, http://www.axoris.be/MissParkerDetails.htm Schematics, gerber files can be found from there. Bye, Moebius

(Tervetuloa midiboxin ihmeelliseen mailmaan ;)) Hi, By looking at HD44780 based LCD specs I think setting display type to 2*40 would do just what you want (Addresses for the last 20 characters of the first line (2*40) equals adresses of the 3rd line (4*20) ect.). quote: main.asm: So, if you want to have 5 selection buttons above display and 5 more under it - You edit those in.. Bye, Moebius /edit:typo

If you can clone EZKIT, sure ;) Bye, Moebius

My only 9v switches places from the fire alarm to the multimeter and back, how come I can't ever remember to buy a second one?! ;) Well, it can also be UNHEALTHY for ya. (That's my excuse ;)) Ever heard of "the hygiene hypothesis"? Bye, Moebius p.s. iceberg, I think you should have a go with a microscope and have a GOOD look :o at your "clean hands" ;)

Answer is simply: NO :p Rather have a look at the Miss Parker: http://www.axoris.be/index.html Well, the problem is that this isn't simply a matter of electronics. Yes, I think anything you need to know is available - there are no big mysteries in DSP. But, are you any good at programming? How's your math, then? My friends studying computer technology have their basic DSP courses at 3rd year of their studies, after completing engineering math, Â C++ and embedded system design courses.. How deep are you willing to dive into this?! And then again. Maybe you should have a look at your DSP's manual MIDI section ;O Bye, Moebius

Hi, Hmm... It will work as a (very small sensivity) microphone, but it ain't piezo, which picks up vibrations from the surface it's connected. So I can't guarantee any success with it. Piezo discs are very cheap, so why don't you buy some? Bye, Â Moebius

YM2612 has more or less different specs than YMF262 - there are many generations of FM chips around. (tx81z is multitimbral alright, but it's still 4op (vs. DX7's 6) - so less is more, or.. what?) Bye, Moebius

http://www.ucapps.de/ ?!? ;D Bye, Moebius

Hi, Cheapest encoders are available from voti.nl: http://www.voti.nl/shop/catalog.html -> Switches: M-SW-ROT. But those have to be modified to non-dentented: http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=parts_q;action=display;num=1092049636 Bye, Moebius

Hi, references: http://www.uni-bonn.de/~uzs159/ 555 based VCO and ADSR 566 based VCO 3080 based VCF http://www.midwest-analog.com/diydel.html 3080 based VCO 555 based ADSR --- Need to switch mains from a logic level circuit? Using this driving a triac will do that for you. A popular choice for intergrator with reset VCO's. Bye, Moebius

Say what? 4Op FM (Dx100) is the second definitive element (apart from 909) on classic Detroit techno/house tracks.. Funky basses, leads, strange noises and squecks ;) That's how its done ;) And checked the specs: Yamaha OPL3 (YMF262) Device 4 Operator FM Synthesis 20 Voice Channels And it's Stereo ;) Bye, Moebius

Check: http://tangentsoft.net/audio/atten.html Sure it cuts fast in MB environment, you'll see 50% of values are at the top 10% of the fader travel.. Not exactly a precision control ;) ..But usually that cutting task is left for the crossfader (IF dj prefers using it ;) ) and basic beat mixing is done with channel faders.. and  then precision is needed.. (well, kill eq's help a lot...)) Bye, Moebius

That's really a simple matter of taking outputs (8ppqn for 32nth notes, 4ppqn for 16nth and 2ppqn for 8th as you already knew, ::)) And using those as switch inputs and then the common contact is trigger output. A rotary switch will do, but if you really want only three positions, there's a special version of a 3 position toggle switch (on-on-on) that could do the same. Only thing that makes me a little concerned is that are those little PICs outputs capable of directly driving 101's trigger input? Bye, Moebius

...on a upper board, bigger SMD on the right side is a yamaha YMF262, smaller is YAC512. ;D Information gathered from TK's previous posts and having a look at Pro Audio Spectrum Soundcards pcb ;) Bye, Moebius

Hmm.. SH-101.. Brings back some good memories ;) Well, implementing midiclock syncronized trigger outputs is possible (and should be done) as well as DIN Sync for old drum machines - and probably will, someday ;) (Don't look at me, I'm not even nearly there yet) And for the DIY solution, already there, go to: http://www.angelfire.com/geek/srlabs/diner.html Bye, Moebius

No problem - We try to help. Bye, Moebius

Hi. Yes, It works with only two cores and sids ;) Bye, Moebius

Well, I wouldn't be so worried 'bout Behringer, they just use fairly common business practices ;D, but Do(p)epfer - known to rip DIY designs :P (Yes - I do encourage NOT supporting do(p)epfer in any way, even not to buy their cheap trafos.)

Does anybody know an elegant way to do this? MIOS supports 4bit LCD mode on HD44780 controllers, and KS0066 seems to be compatible. To set data communication in 4 bit mode, you have to override settings made by MIOS_LCD_TypeAutoSet function at startup. This can be done by MIOS_LCD_TypeSet function, read MIOS functions page: http://www.ucapps.de/mios_fun.html My uneducated guess: Appending (quoting MIOS function reference):     movlw     0x37 | 0x80     ; E1: D.7, 4bit interface     movwf     MIOS_PARAMETER1     movlw     0x24 | 0x80     ; E2: C.4, 4bit interface     movwf     MIOS_PARAMETER2     movlw     0x00         ; LCD type 0     call     MIOS_LCD_TypeSet In main.asm of the application, in "USER_Init" section ,will do ;) Bye, Moebius p.s. Be sure to check MIOS function reference for minor hardware changes needed! ;)

C-c-Check this out: http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=troubleshooting;action=display;num=1094414018 I wouldn't go for the analog solution. (For the reasons you mentioned ;)) And small customation on the firmware are easier and much more elegant, than doing it with hardware. Bye, Moebius

That's the way - I think ;) Bye, Moebius

They do ship to Europe, Quote: "For address outside the UK but within Europe please add £1 per pack for extra airmail costs." from http://www.lazertran.com/orderuk.htm The real problem lies in the payment, as brits are not a euro country :/ - Payment probably has to be in GBPs. And for those like me, not having a credit card, a very expensive bank cheque is the only option. So I would be very interested, if somebody on the euro zone would be kind enough to arrange a bulk order. Bye, Moebius

Antex roxx, Big time ;) Mine has served me for 10 years now, with the original 3mm angled flat tip - just keep it tinned. I have to disagree with this. ;) Hmm, what would those "small components" likely to be? I have worked with my Antex successfully even on some SMDs. A tip: Tip rotation ;) But it could just be that I'm used to it and my 1mm Multicore 60/40 (rosin flux) solder.. The problem with a fine pointed tips is that it makes soldering larger components/pads difficult. To prevent cold solder joints you should be able to hold all applied solder flowing and a larger tip is good for that. SO, if you're antex is XS - I would recommend getting type 50 tip (2,3mm, angled flat tip) as a replacement. It's just slightly smaller than original. Bye, Moebius
