hey man.... what color are you going after? typical colors have more MCD ratings. if your going after blue, white, violet, ect (exotic colors) then you will have a dimmer MCD and way higher cost, usually.
i got mine off of ebay from the user "vdehkl", they are from hong kong but got here in about a week or two tops, and im on the east coast even.
the guy is very friendly and if your after bulk then he gives some good prices. im 99% sure he sells regular colors even if they are not on his ebay 'selling' section.
my 5mm white LED's are supposedly 10,000MCD and they are damn bright. bright enough if you look at them straight on about 2ft away youll be seeing starts when you close your eyes for the next hr. but the wavelength of the color might have a big factor in the "brightness"
also remember that the viewing angle adds to the brightness somewhat. ive got some 10 degree 10mm LED's that are rated at 30,000MCD and they dont look very bright unless you get directly above them. esle you get a diffused section of light that doesnt look very bright.

hey guys, getting worried about a PSU in my 3xLC midibbox...
heres the specs...
3xLC core
24x alps 11M9 motorfader (TK said ideal setting was 7.5V on the MF module on ucapps)
288 10mm LED's for meterbars (obviously not only one hit at once) specified as 20mA each
264 5mm LED's for rings specified as 30mA each
150 5mm LED's for individual buttons specified as 30mA each
24x LCD (yes, 24 of them) but i cant find the power consumption clearly stated in the datasheet:
http://www.crystalfontz.com/products/12864b/CFAG12864BWGHV.pdf
i'll be wanting to use the backlight so keep that in power usage consideration.
anyone got a shot in the dark on what kind of powering station i'll need to get this running all up? im guessing at somewhere near a small city size powerplant. especially with 24 LCD's.
any help much welcomed!

albs.de is out of the V-faders i was told, actually they had like 10 left, not enough for me. might be enough for your still though, might want to email them.
roger, i thought the order was closed on the faders. i need these things in a MAX of like 4 wks. if there was any way you could get/ship before then i could consider but i dont know what your plans are for it :( i really would like the V fader over the lesser grade ones. :'(
-
hey man. not a problem.
gotta be patient usually with these forums. people are spread out over all the world and time zones so it takes a while, luckily i could help you out on this question ;)
i got(getting) mine from www.albs.de, 100mm (which is like 4 or 4.5" travel), the Euro distro of alps japan products. mouser is always out of stock of the fader and it cost alot more.... the penny and giles are very nice, and expensive, and usually used in neves and ssl's (like the name,hehe). but those arent the same type of faders (those are faders with audio tracks and a audio taper, not linear, slope of adjusting). as far as i know no one has tested a P&G fader in a midibox, its thought to work, but not really worth buying 24 of them to 'experiment' with. correct about 60mm vs 100mm, resolution is the same just a smaller travel.
personally i wouldnt even consider non motorized faders. they are such a PITA, might as well use a mouse i believe. if you go faders then go 100mm and motorized halfway decent ones and cut cost in other ways, its the most important part of the LC imo.
on the panel i dont have to much to reccomend, im getting mine waterjet cut. a guy thats building a MB64 ( i think its stickied on the top of this section of the forum) got the company that does that thing to do it. weird name cause they are from germany but have a US division in seattle i think.
np np.

brandon,
hows it goin man. heres my view on it...
only hardware that supports motorized faders is the LC (logic control) system. so that will be your base. which will be better cause your using a host audio program.
keep in mind that this wont work with pro tools. they are to strict with their openness of adjustabiliy in the program for external devices to control it. cubase and logic are what most people use LC for but it can be used for other things if you want, but probably wont need the motorfaders for those...
on your list of things it looks fine to me... i dont know off the top of my head how to control a dedicated plugins adjustable functions like you want to do with hi/mid/lows. but i dont know if this is the best idea, reason being is that thats alot of buttons, and what if something doesnt even need eq, much less 3 bands on that channel, then your just taking up space on your board.
and #6. the gain pot? lol what are you trying to make a live board? you dont need a gain pot cause theres are no pres in here and motorfader is used for gain.
1. If this is doable, where do I need to start planning this thing out?
--- yes, easily doable, im doing a 24ch right now with 200 buttons so yes yours is easily doable. start with what motorfaders you want RIGHT NOW. i havent found an ALPS motorized fader in the states so i'm having to get mine from germany. dont loose track of cost cause they are about 25$ a pop.
2. Would this be ran as a MIDIbox64?
--- nope, LC
3. How much should I plan on investing in this thing until I get it finished?
--- huh? well, you havent said anything about the actual housing so keep that in mind. probably dont want to make a nice/expenisve box and have it in MDF
4. Is it possible, and how hard would it be, to add another 8 motorized faders?
--- easy, add another core module. only 8 MF per core, im using 3x Cores.
5. Where do you guys recommend buying parts? My understanding is SmashTV has most modules ready in kits (which I will gladly purchase ), but what about other things, such as motorized faders, switches, etc.? Could I buy most things from Mouser?
---- MF will be hard to get, panasonics kind of suck and they are hard to find in the states, ALPS are not bad and thats what i went with. Penny and Giles are nice, and at 75$+ a piece i would hope so. knobs and stuff wont be a problem if you want conventional knobs. mouser has a pretty good selection and if you cant find it there digikey has it.
6. I also would like a backlit LCD on it and USB implementation...
www.crystalfontz.com is who i would recommend. figure if you want a graphic or character LCD first though. look at around 30$ for an lcd just buying 1. on the usb you'll need a midi to usb convertor like an MAudio 4x4, which i believe is discontinued but can be found on ebay for around 100$, and just hide it in the box and have 1 usb out, and 3 optional ports on the back of the box for expandability.
goodluck.

hey smash, thanks for the reply.
yes, this will be an 3xLC box(s).
hmmm. let me think about this DOUT again and post when i get back (running out for a few hrs).
do you have this stuff in stock smash? i'll be looking at ordering all of it early in the week if possible.
thanks.

Question 2 (dumb :-[) : Does anyone know where to find something to put on that really small bit of joystick so that it looks like a real joystick at the end ? Is that standard ?
Olivier
you'll have to worry about thread pattern and thread depths buying the end from a different company, but ive seen a few ones that dont look to bad on arcade surplus sites. like the people that fix arcade machines. check into it.
goodluck

also check out
if you need anything smaller. also have nickel and titanium, expensive though.

*beforehand warning*, yes i know its alot and is going to be alot of cores/modules:
3 x CORE
24 motorfaders = 3 x MF module
24 Analogue Pots (pan pots) = 1 x AIN
24 Encoders = 2 x DINX4
150 buttons = 5 x DINX4
288 meterbridge LED's (12x24ch multiplexed) = 2 x DOUTX4
264 LED ring LED's (11x24ch multiplexed) = 2 x DOUTX4
144 standalone LED's = 5 x DOUTX4
so...
3 x CORE
3 x MF module
1 x AIN
7 x DINX4
9 x DOUTX4
so 3 cores will be plenty for that right? 3 cores would support 12 DOUTX4's and 12 DINX4's.
that look ok? im going to be having displays but that wont affect module requirements.
let me know if im off!
thanks.

So long as you don't use the MIDIbox with a display, the order doesn't matter, since the pots are free assignable. A changed order could also be irritating when you plan to use Serge's MIDIbox editor for the configuration of MIDI events
Best Regards, Thorsten.
and how would you arrange if graphic displays were used?
thanks.

heres a better write up on it:
http://www.artlebedev.ru/portfolio/optimus/
i dont know where hes getting the big buttons like the spacebar, i know a company makes the smaller ones. maybe NKK? but they are like 30-50$ USD if i remember correctly. so thats one expensive keyboard.

but the only way to link cores is to use the MidiLink idea right? then i have the 20cm distance between core rule?
im going to have 1 core remote by about 3 feet. whats the best way to do this?
i wanted minimal cables going into the other core box.
i can run a power cable and the midibox connect wires next to each other right? should they be sheilded or is plain stranded teflon wire ok?
thanks!
taylor
-
thanks :)
by 'common midi port' you mean the midi Thru connect to the core?
-
im going to have another core remote from my main core output, and ive got a few questions about the connection between the cores....
1. how far can i go in distance? is this even a problem to consider ( wont be more than 3 or so feet probably)
2. do i have to use ribbon cable to connect the mutiple cores? is cable capacitance a problem? will i have a problem if i use around 16AWG wire instead?
thanks!

with Jitter (a Max/MSP derivitive) you can control video with any controller you want. midi devices included.
might want to check it out.

TK,
by "50 LED's" do you mean at the same time or the memory to program PWM for each of them?
i was hoping on using the pulse for all the buttons and the LED rings (not for the meters though)
i wouldnt be pressing more than one button at a time, but with the LED rings they are going to be going all at the same time if theres alot of panning.
is there no hardware way to do it (like the schematic at the top) and still comply to the hookup pattern for the midibox?
thanks.
taylor

TK,
thanks for the reply.
actually im not trying to flash a button as if i was in RecordArm or the likes, im trying to fade up to and fade down from a button push instead of having it just hit with luminosity all at once.
ex. think the Apple monitor/desktop on and off button. when you touch it it "glows" or fades in and out instead of just coming on and off.
any clearer/advice?
thanks!
taylor
-
you mean which host application? this is going in an LC and controlling Logic 7 pro.
-
thx for the post TK.
could you go a little more indepth? at what level language would it have to be programmed? when you say software side do you mean MIOS or write a stand alone application to control sent voltage, ect?
good idea, will save me alot of $. thank you!

hey all. im trying to implement this schematic into my LED's on my midibox:
it uses to amps, one to bring the LED from 0v to its set voltage, then one to bring it from set to 0v. thus creating a pulse effect.
the parts are pretty cheap, but when i have 50 or so buttons i want to use this with then it gets a bit costly.
is there anyway i could use this schematic as a 'LED master' pulse section where all pass thru this before the LED.
only thing i can think of is it messing up by pressing another button while the one before it hasnt finished its pulse cycle yet.
let me know if you have any ideas!
thanks.

sorry. gotta be patient around here. not a super populated board at all times. people are spread out over all the world so be patient. i know it sucks to wait on a question...
about your 'small sliders'.. what do you mean by sliders? like an un motorized sliding potientiometer (unmotorized fader)?
where are you getting your lit buttons? got a link to share?

Hey Taylor
... not exactly :( Let me explain:
I guess you'll work with the LC protocol. So if you want 24 faders you basically need 3 cores (one per 8 faders) that's how the LC is implemented into the host. So your host software sends you the LCD information for 8 faders over MIDI over one hardware MIDI port.... and the same for the next 2x8 faders.
Now just let's talk about the first 8 faders and at the end you just have to build this package 3 times.
You can have two character displays per core. So you have two displays on your "basic" core, which also runs all the functions (... encoders, buttons, faders). Normally on this core you would read out the display information for the first display of fader 1 to 4 and for the second display of fader 5 to 8. But you only read out the information of fader 1 for display one and fader 2 for the second display. Now you send the same MIDI signal which feeds your "basic" core over the thru port to the NAND Gate, which amplifies the signal so you have three times the same MIDI signal containing the same infrmation (of 8 faders). Those three MIDI signals are feeding your 3 additional "display" cores. One of those three additional cores reads out and diplays the information of fader # 3+4 on it's two displays, the next #5+6 and finaly the last one displays faders 7+8.
Greets, Roger
Roger, thanks, im still reading this over and researching to see exactly what i need.
would the Graphic LCD's be treated the same way as this? or is there some sort of cap on the bandwidth, ect. if there was a memory problem with trying to do all the graphic lcd code on the original core, wouldnt the 24 (sounds stupid, i know) core system that was linked work because they each have their on main core and plenty of space?
thanks.
taylor

Roger,
that NAND Gate is interesting. the 7400 looks like a quad chip. so thats 4 gates right? so four 2 to 1 gates. so that would get me 8 LCDs per 7400 IC right?
what about graphic LCD's? is there a bandwidth or memory problems with those compared to char lcd's?
thanks alot!
taylor
Could someone point me in the right direction
in MIDIbox HUIs

motorfaders or non motorized?
what is your budget? if your basing around 24 motorfaders then get ready to shell out some change man, just as im doing right now.
