It used to be #midibox@EFnet.. now that I /joined, it's mine ALL mine.. buahh-hah-haa.. Klingen, Dan, Smash - You'll NEVER get OPs again ;D M

Well, I haven't made any comparisons - but B40C1500R is the same series as B40C800 and you can directly tell it's ok: rated 40Volts and 1500mA versus the original 40V/800mA.. M

http://www.midibox.org/forum/index.php?topic=5556.0 It depends.. maybe on the number of potentiometers connected? ;) M

Yes it will or not :D Once Optrex reveals the controller or compatibility to HD44780 - It works. It's up to you to be experimental or check the datasheet againts HD44780 based displays. Do whatever you like. Do it! - It might be an experience, Moebius

Remember, I don't know a thing about these breath controlllers... In the page I posted, it shows the breath controller having -8VDC for the voltage input. (Tip) With mods suggested, I think so. At least here it has a negative input voltage. Or Tip (2) -8VDC, Ring (1) Signal, Sleeve (3) Ground. I think You'll anyway need a bipolar supply for OPAMPs to (full) scale it's output correctly for 0-5V inputs MB64 wants. Moebius p.s. You COULD power it with a single AC wallwart and halfwave rectifying for +/- voltages.

I'd say plated are better. Anyway, I'm using an Antex iron, which has a different way to attach the tip. In the years of use it has turned dull gray, but tip is still nicely tinned. (But I usually tin it, when I'm turn it off and wipe the excess solder off while it cools off.) Moebius

It's possible - maybe not for 20€, but close. Here's what I found with little Googlin': http://www.tfe.umu.se/personliga/jh/simple.htm It can be interfaced to MB64 pretty easily, but you'll need a buffer circuit for it. tech blaa blaa: Top part of the schematic shows a buffer to drive M5283P VCA. It's been voltage limited with 5.6V zener so it's pretty close to what Midibox analog inputs want. Simply changing that to 5.1V zener and using 1M trimmer for R19 would probably do the trick. And you'll need a bipolar supply for this. Bye, Moebius

Yes. You connect +5VDC to the core/SID J2. (mind the polarity) - leave the regulator out from the core... ect. The Ground is there, but it's just not marked as ground but Vs. And yes, audio out needs Ground connection. I'd say any bridge rectifier should work. Or 4 x 1N400* series diodes (1N4001<->1N4007) Bye, Moebius

Cool! Did I say Cool? - and shame on us who didn't do this before TK... :'( Thanks Thorsten! M

No problem, man! ;D It's a nice thing You brought this BBD topic to our attention again.. Wisefire: There are 2 ways to control these from the core, I think: A. Generating (biphase) clock signals to drive clock inputs BBD. I don't know much about MIOS timing, so I don't know if this is possible for, say Chorus/Flanging effects (clocked fast). But this would enable direct control of the delaytime - at least for longer delay effects. B. AOUT+Voltage Controlled VCO to clock BBDs. (C. Using normal MN* clock chip and vactrol/LED+LDR combination to control resistance of the clock circuit) Bye, Moebius

Like June -04 old, even on AH.. M p.s. Still guessing those are Shanghai Belling BL3*** parts marked as MN3***..

Because sometimes News ain't that new :D M

You shoudn't believe everything they tell Ya on AH, kokoon :P M

Hi, I don't have MPLAB and don't know which file to load. But the file your referring to is empty. Bye, Moebius

Try the yellow pages. There should be several sources available for plain sheet metal cutted to dimensions even in small quantities. Bye, Moebius

Do you speak .dxf? M

I know. I'm sorry, if I sounded a bit rude. These people just deserve our respect. (Just look at the Pixie BOM - It's a bit more complex than modularized MBHP designs. I know I wouldn't enjoy hand picking all those resistors..  :P) I'll give a try on this one, can i ask you guys - is any of these ICs hard to get: CA3080 - Transconductance Opamp [discontinued] These OTAs are getting harder to find. You can still get them for a reasonable price, but local shops or major distributors might not be able to help. LM3900 - Quad Norton Amplifier Being a Norton, not a typical OPAMP, might be a bit hard to find (?!) CD4069 - Hex Inverter Unbuffered CD4069UB really? Just make sure you get the Unbuffered type. Whoops - I forgot, those polystyrene caps could be a bit hard to find and a bit expensive. Pointers: 1N4001 50V 1A Diode (or any 1N4001-1N4005 range) 1N4148 Signal Diode   (or 1N914) +5V 1A Regulator     (LM7805) +9V 1A Regulator     (LM7805) Cheap and easy to find: CD4007 - CMOS Logic CD4011 - CMOS Logic CD4013 - Dual D-type flip flop CD4015 CD4016 - Quad Analogue switch CD4024 - 7-stage Binary Counter CD4030 CD4051 - Single 8-channel Multiplexer CD4081 5V0 Reference Diode (making a wild guess, It's actually 5.1v Zener  :P) Transistors are regular small signal PNP and NPN types, very common. If you can't find 'em, can be susbstituted easily. Bye, Moebius

True, so true... :-\ M

Hi. Mr. Laurie Biddulph is a well respected figure in SDIY. I haven't dealt with elby-designs, but also haven't seen any complaints. He mostly provides PCBs and kits for designs that are not supported by the creators themselves - oh, with his own improvements. So, what could be called a favor for SDIY community is also business for him. It's only logical for him to keep PCB design documents private?! Remember, the schematics are there. Nothing but Your skills and dedication (which might go hand in hand), keeps you from designing a new PCB from the scratch? ::) Bye, Moebius

The EL backlight should have only two contacts .

Congratulations, Boys! The first ever transaction/trade on fleamarket and looks like it works. Let's keep it that way. M

Great! Yellow 15 pin D-connector sounds just like standard gameport/midi. Go ask for "a soundblaster midi cable" from your local computer store (and compare prices if you can! Some stores have a huge profit margin in these) You'll need that midi connection for uploading MIOS and SID app to the core. Thanx, Moebius

Read the documentation again and use the forum search function ;) In MIDIbox64E it's possible to use pots (64 of 'em) with encoders and buttons. This thing was discussed not a long time ago. Bye, Moebius

Hi. Should (Must) :) Ok. The PSU puts out +5VDC, right? You have read the schematics carefully and noticed, this goes to core J2? (remember the polarity).. If plugging the core to PSU drags voltage lower, it could be a short somewhere in the core. Bye, Moebius (p.s. Do the core debugging without MBSID connected - and yeah, remember it still needs the regulator and that +14VDC from the optized PSU circuit)

I don't think you have done everything right ;) You should be able to measure +14VDC between the ground and the output of the 7809 regulator. Did you realize, that 7809 "common" (or middle) pin is connected to PSU +5VDC? Bye, Moebius
