good eye stryd :) its apparently one of the old bomber microphones from world war 2, so somewhere between 41 - 45. Model number T-30-V. I am all for history and conservation but I doubt this is a particularly rare piece, it cost all of 10 dollars on ebay and I have spotted others on there in the past.

Hey all, look at purchasing some rotary encoders for a mbSID im building. Has anyone had any experience with Bourns encoders model number: ECW1J-B16-BC0024 ? I was wondering if anyone could tell me how they feel? They are a bit more expensive than other ones I have been looking at, but I am willing to spend a bit more money for better quality. However, if I am not getting any more quality for my money...stuff it! I will go with the cheapies :) any help much appreciated, thanks guys EDIT: here are some pics of them

Hey all, So a little while ago I picked up an old Shure throat microphone for cheap. Its basically two contact microphones that sit on either side of the voicebox and pick up vibrations that way. The jack on it is straight out of a science fiction movie so I figured I would wire in a new one. There is a device that lets you speak or not speak built into the wire (kind of like a walkie talkie speak button) and from that to the jack runs three wires...but from the microphone to the button runs two. My noob question is this: is the signal mono or stereo? I bought a stereo lead because I figured two microphones would mean two signals...but wouldnt only two wires running from the microphone suggest it is mono? and if thats the case...how on earth does that work? if it is summing the signals together isnt there a really good chance of them phasing each other out? That is a photo I found on the net of the throat mic. basically, those two black little disks sit on your voicebox... any help much appreciated! thanks guys

well, due to uni commitments I haven't had a chance to fully read up on the Encoder issue, but I managed to take a small step in the right direction :) Due to a bit of confusion with the other project im working on atm (building a strobe) I had a brand new stereo 6.5mm socket at my disposal, so I decided to use it for the mbSID :) I am no electronics wizz, but when I was buying it, it was a choice between this one, or a DPDT (dual pole dual throw) socket...does it matter this one isnt DPDT? to be honest, I can barely remember what that even means... Anyways, on with the picture! Like I said...its not much but its a step in the right direction :)

I had a read through that article stryd_one but I couldn't see too much that could help other than how to remove the detents?

OK, first question. Will the following rotary encoders be able to be used on the mbSID? Specifications: Weight: 11g Electrical Output: 2-bit gray code Closed Circuit Resistance: 3 ohms Contact Rating: 1 mA at 5 VDC Insulation Resistance: 10 megohms at 250 VDC Dielectric Withstanding Voltage Sea Level: 50 VAC minimum Electrical Travel: Continuous Contact Bounce (15 RPM): 5.0 ms. RPM (Operating): 100 Mechanical Angle: 360° continuous Running Torque: 30.6 to 204 g-cm (0.42 to 2.83 oz.-in.) Shaft Side Load (Static): 2.04 kgf (4.5 lbs.) minimum Weight: 3 gm (0.1 oz.) max Operating Temperature Range: -30 °C to +70 °C (-22 °F to +158 °F) Storage Temperature Range: -40 °C to +85 °C (-40 °F to +185 °F) Humidity: MIL-STD-202, Method 103B, Condition B Vibration: 30 G Contact Bounce: 10~55~10 Hz / 1 min. / Amplitude 1.5 mm Shock: 100 G Rotational Life: 30,000 cycles minimum Switch Life: 20,000 cycles minimum IP Rating: IP 40 Wave Soldering: Sn95.5/Ag2.8/Cu0.7 solder with no-clean flux: 260 °C max. for 3-5 seconds Hand Soldering is NOT recommended Power Rating (Resistive Load): 10 mA at 5 V DC Switch Travel: 0.5 +0.4/-0.3 mm Switch Actuation Force: 360 +153/-102 gf (5 +2.1/-1.4 oz.-in.) Im aware of what kind of pots are needed for the MB64...but I couldn't see it written where it says what kind of encoders to use? Could their button function be used to trigger anything on the mbSID? or would it be useless?

Well, after reading on here for over a year and considering various projects, I've finally bitten the bullet and started making a mbSID synth :) all I have done so far is source a SID chip, purchase a 2x20 LCD and track down a box to squeaze it all into. Im going with a cigar box...dont know why...just thought it would look amusing :) Here is a pic with the LCD display in place after varnishing the box. I thought it would be an easy box to work with but I was horribly mistaken. Soft timber that marks too easilly, and is way too thick to cut through easilly... any comments/ideas? I am currently practising my electrical skills on a few simple kits before I take on this properly :)

ahh ok, cheers, im guessing these should be linear encoders? 10k? or is it different to the midibox64? Is it possible to get these without detents?

Hey all, been a while since I have been on here. I am finally getting around to building a simple MBSid :) I am using a cigar box to house the project, so I dont have massive amounts of real estate for running a complete face setup. I was wondering if anyone could tell me the following. I am planning on running the basic minimal setup as covered in the User manual, but Id also like to have pot control over things like the Filter and LFO. Other things like the mod matrix and stuff I have already decided I wont be implementing in the front panel. Is it possible to only have one or two of the sections (like Filter & LFO) set up, and the others without dedicated controls? Cheers Andrew

if you want really decent pads, go for an M-Audio Axiom....they are absolutely awesome. Velocity Sensative...plus you can easily swap them around so them send CC data instead....its a suprisingly intuitive way of controlling midi data....very good for...mm...whats a good word...hehe...transducing? human emotion.......

ahh, my bad! cheers for the heads up :) Exterior of it was a bit dusty, gave it a rub down with some eucalyptus oil to get all the gaff tape gunk off it...looks good as new now! :)

Agreed with everyone above...panellssss :)

do what I'm young and stupid enough to plan...do them symultaneously! I couldn't choose either... And whilst I have the QuadraSID plug-in, and a more-or-less functioning FM synth i wrote in max/msp...the sexy appeal of actual hardware is relentless :)

Yea :) I did a bit of reading and realised it will be a bit difficult to connect via computer, but that wasn't my original intention so if I cant do that it doesnt matter too much... I was basically planning the following singal path (probably not the best re. latency, but its better than a network that drops out intermitently): My Computer>USB CONNECTION>Novation 25SL>MIDI CABLE>TimePiece>MIDI CABLE>Novation 25SL (everyone else...4 other ppl from memory, all identical setups)>USB CONNECTION> Their computers... I take it I can send a signal (Midi clocksource) in one input, and send that signal out as many outputs as I want? Its proving to be a pain in the ass finding a manual for it (never thought it would be easy :)) and hehe yea, when i said not the usb one i meant not the AV :)

not exactly :) there are 2 for sale on ebay at the moment, one in OZ. Id buy it and open it up...but if it takes a fair amount of force to use then it probably isnt worth spending the cash on..as it wont be overly useable for actual performing :(

So, I'm in an electronic group at uni (I study music) and we had a recent performance that had a nasty issue. We were running midi sync via MAX/MSP over a network we set up, but the router kept dropping the signal (turned out to be faulty). In my frustration afterwards I did some searching on ebay and came across a MOTU Midi TimePiece II (not the USB one)...I watched it and slapped a bid on it at the last second. It arrived today in perfect working order :) So, how much did it cost? $100? no $50? no $20? no.... $14.50 :) australian...thats probably about 6 pounds to those from england Absolute bargain :D

Hi Simo, im sorry, I dont think I full understand what you mean? Do you mean if I run that directly into a computer, there is software already written to interpret the signal and change it to MIDI?

...I'm sure it would be way too hard, but I thought it was worth asking about anyway. Don't know how rare they are, but I've seen one or two Commodore 64 Koalas around over the years. For those that dont know what they are: from what I can see its basically just a very early form of graphics tablet. It's touchpad size is almost the same as a Kaoss pad.... how difficult would it be to turn one of those into an XY midi pad? It is already designed to take physical data then send it into a commodore 64s joystick socket...could this be somehow changed into midi CC information? more or less how the touchpads on novation SLs work... Just a thought :) Andrew

bummer...those red ones would have been perfect :( does anyone know where to get these from?

this is more of a wank factor/bling factor thing I agree :) but having both would be useful if you were say using it in a dark environment :) so all i need is dual 10k linear taper potentiometers? I guess also with all the awesome work people have done on here, Im looking to do something a little bit unique with mine and try something that others haven't yet :) or has this been done?

...as ive said in many posts so far, i am a newbie when it comes to electronics, but whilst doing a uni assignment my mind wandered. Please bear with me on this one, its going to be worded horribly as I dont really know the right terminology to use. Anyway, in a MB64/MBSID/MBFM (the only ones ive looked into), would it be possible to use one of those dual potentiometers like the following: (Horrible example of what I was looking for but I'm pretty sure you will know the kind of thing im talking about) First question, by looking at it, im taking a wild guess that you can run two currents through it and have both controlled by the pot and outputted separately? So could you, say, have it working in the way that they usually run, then have the separate bit of them recieving a different source of power (say, a battery pack) and have them controlling some form of light? (im guessing you cant dynamically dim an LED so im not entirely sure what kind of light you would use). but anyway, basically the idea is to have a little light next to the potentiometer that brightens/dims the more the pot is turned....just a way of having a visual reference on where all the pots are at? and if its powered separately by a battery pack or something, a: it isnt sucking power out of the modules, and b: you can switch it off when you dont need it.

ooh, ooh, thats a question I think I can answer! on uCapps there are different versions of the DIN module listed. he means 3 DIN modules which have the 4 "74HC165" ICs. here is a schematic off uCapps: and here is an example of a 3DIN module: anyone feel free to correct me if im wrong, and bludgeon me over the head with a hammer :P

ahh sweet as, sounds exciting! :D

Brisbane :) For anyone else that lives in brissie, im southside...about 5 minutes walk from garden city :) Yea, theres a jaycar about 10 minutes drive from here, might head there next weekend after my exams are over for uni and go scrounging for things i need/want :) thanks!

a tad bit confused with the post...25au each....but they are sold in groups of 4...so this means minimum purchase is 100au?
