Making my own KEYBOARD?

Question

I'm trying to make my own keyboard with many less keys than a conventional one. It would only have about 10 keys. I have most of the hardware problems figured out. Now comes the part about interfacing it with the computer. Could I have each keypress event send power through a specific resisitor, which would send power to a capacitor? The power would then be sent through the data channel of a serial cable and the pulse would be measured in terms of time by a program I will write. Is this at all possible or would I absolutely need to buy an ADC. If I used another channel besides the data line in the serial cable, would I be able to avoid an ADC? Thanks a lot in advance. Please either answer here or email me at [e-mail]!

Now that I think about it, I would have to use several capacitors, the resistors wouldnt have the desired effect

Yeah, im just trying this to make it as simple and cheap as possible

I suppose so...im just trying something, this is more of an experiment than anything...

I think youre right in the end, I'll just rip apart an old one. Another question though, I just backlit a keyboard with some leds for the hell of it. If I tied them into the power for the keyboard, would the keyboard still have enough to function

dumb question, nm

Answer 1

why?
you would probably need a microprocessor,
keyboards are keyboard port or USB

just use the parts from an old keyboard,
like the circuit board.and cable
make your life easier.

Answer 2

The songwriters "own" the track, no be counted who's interior the band. In different words, if a band has 4 individuals and in user-friendly terms 2 of them write the track and lyrics then those 2 own it. If Roger Daltrey needed to re-checklist his vocals, then that's actual superb assuiming the Pete Townsend wasn't gonna treaten to sue and Roger substitute right into a contributing songwriter. despite the fact that, there is no clarification for Daultry to choose for to alter his vocals. Doing so might, maximum possibly divulge his barriers (that's the comparable clarification why Robert Plant won't do a Led Zepplin Reunion) If I take place to get offended over it, there is no longer implication of possession as a fan. that's like asserting, "i'm offended at the same time with your question, yet i'm a fan. So, I now own your strategies (if no longer all of you). Plus, claiming possession over some thing reason your offended, is the comparable as stealing. No, track would not substitute into the international's components (till it Christmas Carrols or "chuffed Birthday", songs so previous that's imposable to hint down the songwriters.) track is partly owned by checklist labels so if an artist would not own their track (and somebody else did no longer purchase the rights), then the label is granted possession. Artists could and do have the appropriate to toy around with their previous artwork, there are lots of re-recorded songs and finished albums already obtainable (to no longer point out all of the remixes of songs).

Answer 3

Hi. A keyboard works by connecting a unique combination of wires which the computer recognizes. The simplest ones simply have a grid of wires, one vertical and one horizontal. Touching the letter "a" will connect just the vertical and horizontal wires that cross at "a". Hope this helps.

Edit. I built my first keyboard from magnetic reed switches which closed when a magnet, attached to the key, was pushed down. Worked for years and was still working the last time I fired up my Timex/Sinclair 1000.

good luck with that! =)
