PSX joysticks, how I haven't remembered of that one before.... :) What is the value of their resistance, how hard is to fit them onto a frontpannel?

Ahother tread,LOL. Anyway, why are you so much against encoders? Expenses, complexity, ....?

Plz tell me, can touchsensor be built out of a metal plate[we are talking about a scratchplate]?

I'm a sucker for digital input...hehe. I found something interesting: Basics: http://www.societyofrobots.com/sensors_encoder.shtml The wireing: http://www.societyofrobots.com/schematics_infraredemitdet.shtml About that film with gradient printed: http://www.societyofrobots.com/schematics_photoresistor.shtml This would be easy to implement mechanically: http://www.societyofrobots.com/sensors_sharpirrange.shtml

Every big discovery has been achieved trough experiments. You of all people should know that if u r studying computer science. You do have programming, right. Does the compiler tells you (when it finds an error in the code) "Yo dude, there's an erra', the exact code should go like this..."? No! Or even worse, when you have a runtime error, program is succesfully compiled but not doing what it is written for. Then you have to track down error by your puny little self because YOU DONT KNOW WHAT U ARE DOING EXACTLY! On the other words, if you don't get this last moogah's explanation then we the "computer scientists" are soo sory to have such a specimen among us.

I have few things in my mind, first, Adding a VU meter and second, adding some scratch plates connected to some kind of encoder [i'm not sure what exactly]. And a question how to split a main/monitor signal [one to go to the amp, second to the vu meter] without loosing signal quality, would a simple Y-cable be sufficient or there is some circuit (ie. Audio Splitter)?

Rip wires from old pc cases, cd-rom audio cables, PC power supply [Fdd connector] and all that have such connectors that can fit to SIL headers.

A least the wheel aint freehanded.

I have bought a C128D for 0.5 euror bkz of sentimental reasons for it was the first computer that I had.The only difference is in casing, mine was plastic and this one is metal. I'm thinking of turning it into a midibox but case is too big for my needs(32x40cm) and C128 is in perfect case. What would you suggest? http://www.zock.com/8-Bit/D_C128D.HTML http://www.zimmers.net/cbmpics/c128ds.html

Let's not go to much offtopic here, I'm hopeing this tread to be productive. Laser cutted piece of non transparent plastic. I think that Sasa D. would agree with me. Question is how to lead signals from encoder if it is moved with handle.

Done it! Connected 80k & 37k in paralel then all that to one more 80k to achieve a resistance of 105k, MIOS UPLOADED So simple....and I'm testing for problems tru the whole last week.

Well, that's why I came here for ansvers, I too don't get it. [i didn't know it reboots if doesn't get a upload start, sorry] How about this, the logic voltage levels are offset and therefore pic doesnt "get it"? I've forgot to menition that there is nothing in the OCoupler position and that instead of R6 (1k2) was put ... CRAP!! 100R Let me get back to you.

A little idea TK, is it possible for you to put some different message on startup that would signify powerup[the idea is to easily detect reset]? Pseudo<startup> <upload request> <upload request> <upload request> ... Since I've read at lest 3 posts with Psu problems and rebooting. What do you say?

Word.

New MIOS 7_2 Report: Starting upload of mios_v1_9_pic18f452.hex Hex file contains code in MIOS range, forcing reboot! Received Upload Request Sending block 00000400-000004FF Error: Received unexpected Upload Request Sending block 00000500-000005FF Error: Received unexpected Upload Request Sending block 00000500-000005FF Error: Received unexpected Upload Request Aborting after 3 errors

So, I flashed/burned the pic and for the last couple of days I can't find a way to solve my problem. I am receiving Upload request but PIC won't accept data/send back checksum. I don't have the scope to check stability of power imput and I have read most of MIOS upload problems(and tired some of the solutions). I also erased the pic, check it for empty space and flashed once more.

@TK: That's just ruude!! How do you mean to get payed if you don't want to write a GOOD documentation upon a request from someone with 10 posts?! :) :P BTW: I' intend to try to make some order in that whole pile of information when I get my MB done.

Pinout would be nice, tnx in advance. Either way, that PS/2 intercafe will be an interesting thting to toy around [let's see, a trackball instead of 2 encoders; custom, 2xKeyboard...nice bunch of keys]

Oh, I think I've 4got to mention that thiese part are supposed to be "recycled" from old mouses[mechanical] or cheap mouses[optics]. Anyway, I learbed something new, today, tnx rabbit. Btw, I'm looking forward to complettion 0f that ps/2 interface

My preference is MJoy. Here is what I call a MicroBox[attached]: -2 bare pots -1 twostate switch [select pressed A/B buttons] -1 unused pushbutton [wired to button C] -housing: box that used to hold sticks for celaning ears I common work I ise it to control dry/wet effect output on mie SB Live! kx driver In Traktor, well, that's another story... [edit:] 4got to attach a pic

Very nice idea Sinnsyk but I wouldn't want that on my controller it just aint right. And by the way, traktor does have an option for such controlling of song, via one pot you can scan trough entire song[it would be nicer with encoder tough, then you could set it to software pickup and just roll away]. Just found out: you can actually scratch with a pot. But it aint the real ting. There is a DECK SCRATCH ON command wich would be tied to touch sensitive paltter [note on] And the there would be sent a scratch offset wia DECK SCRATCH command [64+/-64 controller offset] and the at the end when the platter speed and record speed matches DECK SCRATCH ON [note off]. Get it?

stryd you ar a willy one but your willynesnesnes gos the other way than mine. If the platter is moving at measured speeed X and we add a constant C1 to it so it would be equal to 64 and then we do the sam with measured speed of the record (Y+C1-/+C2) to align thiese two inaccurate measuring devices [two optical mouses] and then we take into accout the glitches so let's sat +/-2 to difference between a values you get the stable system without changes: X+C1 = 64 = Y+C1-/+C2 Why do we have to do this: bkz we need to know when someone lays hand on our record. See CDJ-1000 has a touch sensitive surface [or more probably a touch sensor] on the platter We....don't. We measure offsets. I know it is the hard way but I can't see your way working and I also can't see my way working without a nice test/benchmark. So when someone stops the record the right side of equasion goes some way (up/down)...and a kontroler starts sending messges, what kind od messages, the Traktor compatible wind messges. +64/-64 depending on the speed offset between the platter and the record. There would be no measurment of the needle position [i have no need of replicating NI FS] Also Traktor has a specialized input options: -MIDI - Incremental This should be checked for controllers sending incremental messages (endless knobs). If checked, three further parameters will be offered: -MIDI - 4 Control Mode Use this option to assign the NI 4 Control MIDI hardware incremental mode to a knob. -MIDI - Sensitivity Determines a fixed transmission ratio between hardware knob and software parameter (at zero acceleration). -MIDI - Acceleration High values of acceleration exaggerate the knob’s speed - the faster the knob is turned, the more quickly the rate of change in the parameter. Conversely, turning the knob slowly will allow finer tuning of a parameter. To be honest I can't be sure what combination would work in this scenario but I believe it is do-able.

Transfered mie pic to flickr, it accepts that.

Noo, I't has something against www.freewebs.com

It differs, all of you are skipping a point here, when you scratch, you dont move the turntable platter, ony the record. Thats what mats are for, they go beteen the platter and a record. The midi doesn't have enough resolution, right but what if you are sending only the offset. This new idea of mine should be tested/benchmaked: One optics to read the movement[speed, whatever] of the platter and second for reading the movement of the record. Divide them, trim them down with some constant [i can adjust the code] and you can send the offset in speed beween thiese two. Offcourse you would be needing a turntable with a working motor [or something rigged "just-to-work"].
