ok after a little chat with smashtv last night i will be going to use the original panasonic faders i was looking at first of all, smaller fotprint and smaller travel on the fader but it means that things will be in proportion better and the case will be smaller. as the faders are only for the filters adsr its not an important feature its so precise to have a larger travel for them. at the end of the day they are 10k linear faders and will work with the mb64e and ain board, im trying my best to keep true to the replica design, so today i will redo the fader section and move a few things around then i will check over the weekend with a 1:1 printout onto adhesive backed paper which i will then stick to a stiff card, cut out the holes etc and mount the parts to check layout, if im happy then its off to the cutters.

well i still have a few little placement issues to iorn out tonight, i think im going to do a little more and then not send the files tomorrow but finish up tomorrow and then over the weekend check things over for anything i missed and then send it out. i still have 8 momentarys to place and the 8 buttons for the mb64e to place also, apart from that its pretty much finished casewise. main dissapointment is the faders, too large for the unit really, i did find some dual gang 10k linear faders that were smaller but i cant see the tech drawing to see what sizing would be like. heres the llink, if these would work with the ain board then i may get them actually and they will make things a little better, but smaller faders again like the ones used in the spl racks would be even better. http://www.maplin.co.uk/Module.aspx?ModuleNo=2215&C=SO&U=strat15 does anyone know if those faders on the maplins site will be fine with the ain board on my mb64e build??? the plan now is once cut, to have it sent back un powdercoated for inspection and a trial fit of everything, and then if its good i will then get the powder coating done

im now surrounded like a kid in a sweet shop with the goodness that is smashtv's kits ;)

well today the kits arrive and i can get them all built up and connected together over the next few days. as soon as i have got the core 1 ain and 1 din board assembled and connected i will connect the pad array together and see which will be taking the matrix for input. so the internals will consist of the following items. gm5 for midi input 2 cores 4 dinx 1 ain 1 dout 1 x mb64e for bpm 1 x midimon with small mtc display casework is ready for the lasercutters and then powdercoating, im then going to see how much it will be for it to be silkscreened using a company here in the uk, failing that its lazertrans again.

rabbit. from what i can gather he is saying that when he presses the button for mute say on the down press the led lights up "on state" then when he lets go it turns off and the mute doesnt stay on. so im guessing hes asking if he should use a latching button for this so that when the button is pressed and released the mute stays in an "on state" then when pressed again goes into the "off state" similar to having a latched button. im guessing thats what he means from his pigeon english.

i think you are reffering to using latched switches and then having the down state as on and then until you press it again its not off. im sure i saw a thread about this the other day. http://www.midibox.org/forum/index.php/topic,14000.0.html

let me check in the manuals for that switch, i have the mec manuals here. ok i found the page in my manuals and if you go here you will find the right pdf file : http://www.mec.dk/files/webMPCBandCircuitDiagram.pdf scroll down to the circuit diagram, as these are single pole switches its an easy connection put the feed into pin 1 or 2 and then the out to pin 3 or 4

its quite disturbing that you decided to take a picture of you wearing your wifes underwear let alone post it on the net!! lol :o :D :D :D

I WOULD REALLY LIKE TO HELP BUT I CANT HAZ CIRCUIT DESIGN FOR THIS

i missed getting hold of smashy before he shipped my latest order out so i need to buy a spare ain board and parts if anyone has got one lying around they dont want. i will pay via paypal the full price. thanks

had some details about the pads today, so im hoping that just linking them to the din board will be fine, just in case im going to get another ain board. i hope the mb64e will let me have 2 ain boards attached should i need it. piccy but i also had this info from the guys at mpcstuff 1. Durability: 100,000,000 cycles 2. Max. current Input: 5mA cm2 3. Operating Voltage: 1 - 5V 4. Resistance (not activated > 20 Mohms 5. Resistance (activated 2K - 40K) using a 1.2kilo force. 6. Environmental Temp. range: -50C to + 90C, 95% relative humidity 7. Inks: Carbon = Acheson 423SS or equivalent, Conductive Silver = Acheson 725A or equivalent, Dielectric - Acheson 451SS or equivalent FSR - ECM ink system (DB24,SE2 & DBE solvent) fsr info.JPG fsr info.JPG

i have done all i can for now, so i will have to wait now for my parts to arrive from smashtv as for now im just taking some time out i have to finish fine tuning the case but when its ready i will put some pics up while its done at the lasercutters and powdercoated.

thanks lyle, i have got an ain coming anyway from smash so i can try it on that also as well, and if thats a better solution get another one but we will see whats what when my kits arrive. at the moment im busy laying out the casework and working out all the pem placements and clinch nuts placements. i have to keep remembering to allow tolerance for the parts and the powder coat.

when i bought them i was under the understanding they were just simple conductive pad sensors not fsr, thereby they would act as momentarys. lucem that would require that for each sensor pad then? which would mean 16 duplicates of the circuit? it would be cheaper and better time efficient for me to just do the button matrix board under the pads.

i have looked and i dont have the slightest clue how to implement them as all im finding are ic ones. if when i cnx the strip to the din it doesnt work i will just bin it and build a 4x4 matrix of micro momentary buttons and float the rubber pads over the tops. if i had known the sesor pad was going to be fsr rather than conductive then iw ouldnt have wasted my money in the first place, i would have just got the rubber pad and made the matrix for much much less.

i recieved an email from one of the engineers this morning with an attatchment of hte pads details, i will have to get in touch with him again as there is no info about the pads impedance/resistance. i will have to change the ffc zif connector i have got because the pitch is different but thats ok as they are pence to buy. if i get permission from them i will put up a copy of the pictue pdf i have been sent so others can learn from the info etc as well. i have asked about getting a standard conductive pad array made, which instead of being an fsr would just be a set of internal conductive pads and the whole array would work as a basic momentary switch array with no fsr functionality thereby eliminating connectivity issues. im going to ask the price on a prototype unit and take it from there, all in all this is an interesting project now as im now learning about fsr tech and about the sr chips on the dinx boards (must admit though... the sr details are some serious reading!)

this is the reply i got from interlink about the ones they used to make for the mpc Please see comment from engineering: “The resistance between a common trace and a drive line is a function of applied force. It ranges from open circuit at no force, to 100kOhms at light tough, to around 1kOhm with a very heavy press.†however im still waiting to hear back from the guy whos currently making them now and he is the person who invented the fsr technology he may give me more detailed information i hope.

thanks lyle, lucem gave me some info in chat also. i recently spoke with the gentleman who actually invented the fsr technology, he was most helpful and very nice to talk to. i ahve sent him lots of pictures and information on what im building and about the forum and ucapps site. im hoping that he will be able to tell me what the impedance is soon and i can go from there. it will be great if i can use these pads on the bpm controller im building, otherwise i would have spent almost $100 on something i cant use!! and i would then have to make a momentary button matrix and sit it under the rubber pads. but space the buttons just under the pads so that they dont depress until you actually give the pads a good press. thanks again lyle.

ok i got my replacement pads and pad sensors however i have a quandry. the sensor array uses fsr force resistive sensor harder i press less resistive it gets, now how can i use these as momentaries on my dinx boards????? because i do not have a clue how! this page i have found from an old pdf from a company that used to make them for akai mpc's shows some sort of circuit that makes one some form of switch but would i really have to make a seperate board just for this? there must be a simple way to use them? (update this looks like a good option for using them prehaps?) http://www.active-robots.com/products/phidgets/datasheets/1121.pdf any suggestions welcome thanks!

thorsten, i think no-one understands you because even when you try to talk simply you still talk "genius" you are the resident albert einstein you know!

momentary tact switches

yes. you have the 8 non motorised faders on the ain board if you want motorised you add the mf board, the pots will be encoders to go on the din they are endless rotary encoders, which means you can turn them 360 degrees full circle no stops. and the buttons connect to the din also, remember you will need 8 buttons for the menu system, and you can use serge's pc editor for it, also look at a bankstick for it as well to store setups. if you need more info just ask as for how goto for buttons http://www.ucapps.de/mbhp/mbhp_dinx4_32buttons.pdf'>http://www.ucapps.de/mbhp/mbhp_dinx4_32buttons.pdf for encoders http://www.ucapps.de/mbhp/mbhp_dinx4_16enc.pdf'>http://www.ucapps.de/mbhp/mbhp_dinx4_16enc.pdf for motor faders http://www.ucapps.de/mbhp/mbhp_mf_interconnections.pdf'>http://www.ucapps.de/mbhp/mbhp_mf_interconnections.pdf lots to read on ucapps.de http://www.ucapps.de/

i would def be interested in two of these , maybe four if need be

apologies for the lack of updates: well im still waiting for my wood sections to be finished, im not in a rush as i want them to be right first time, but im in a queue for the beech to be treated. so in the meantime im playing around with some graphics for the front panel, im not sure what im going to to with yet as im still trying to get things to do what i want them to do in illustrator. i managed to make some layouts using the dxf files of the case from solidworks as templates to work off, imported them into illustrator and drew up what i needed. when i finished the first set of designs i printed them to a glossy stiff paper and then after a rough cut out placed them on the casework to see what they would look like. i need to refine things a little more but its a start, heres pictures of the look im going for the arturia origin style of graphics. as soon as i get what im looking for i will then print to lazertrans paper and do the transfers.
