Software can be modified, hardware can't. It's easier to sell and buy
objection!
i wouldnt say that hardware cant be modified.
this is because you have never see free hardware.
woot? not only i have seen it, i actually do it: http://multio.mamalala.de to give only one example ..... be carefull what you wish for .... ;-)
sorry.i made a mistake here. so, i don't undestand you : why do you say hardware can't be modified, as that what you're doing?
once you have the shematic of your hardware, it's easier (at least for me) to understand how does it work than to undestand how does a software work.
the good point of a hardware is that you can print the all shematic on a big piece of paper. you can't wih software (how many page do you nead to print pd code?). you can have everything in front of you with hardware developement. not with software.
if you know all used electronic parts inside-out, then yes. otherwise you also have to read datasheets, manuals, etc. taking the iobox as example, the datasheets of all used parts will give a higher pile of paper than the printout of pd's sources
adding compiler documentation will add more paper if you really whish to make a competition ;-) (well this is stupid as i don't think it's really important to discuss if hardware or software is easier).
[...]
i can take a bunch of ttl ic's, memory, microcontroller. all that is needed to make it work is to know whats an input and whats an output, and connect these. with analogue circuitry you _have_ to do calculations to make it work.
to make TTL work as you wish, you also have to think. i don't see diference here.
for example, a transistor alone isnt of much use, you need at least resistors also to make it work in a meaningfull way. and those values have to be calculated. in digital world, i only need wires to connect the pins of the chips.
you don't plug wire randomly, as you don't put random resistor when you use transistor.
i dont have to care about bias points, positive/negative swings, etc. as i would need when building an amplifier stage.
yes, ok.
maybee i do not express myself clearly. the only thing i wanted to say in this discution is that using linux is not enough to be free. maybee it's harder to make hardware thant software (i don't change my mind anyway), but this is not really important.
in fact, one could look at it (the digital part) as "pd with real objects".
pd with real objects is more analog electronic than digital electronic. pd with real objects is modular analog synth made 20 or 30 years ago.
agreed. but i was more refering to the simplicity of connecting black-boxes (in this case chips vs. pd objects) instead of caring about the inertia of them. to build a analogue synth module, even a simple oscillator, you need more knowledge than you need to build a running light with one digital chip (cd4017).
at least you nead to know that you nead a cd4017... you have to learn thing befor doing digital electronics
there is a lot of projets to build free pd with real objects. (I personally have build few of them, for the one interested with free music.)
do you have any pointers? im interrested in such stuff generally .... soon i will put mine online, just need to "polish" them so they can be put online ....
i don't have bookmark anymore about this, (as i was working on this many years ago) but i've got a lots of shematics that i'll send you off list.

(as this discution is highly OT, i just got further : how many people in this list have listen to ANALOG FM synthesis. i never succed doing so great sound with pd or any other digital stuff.)
true.
its just that many people are not interrested in creating new hardware, for whatever reason.
siting on a chair, drinding beer, eating pizza :-) it's a joke, but to be honest i never drink coffee becaus it's incompatible with hardware soldering, so yes, ther are some (bad) reason to focus on software better than hardware.
many are afraid to handle chips, a solder iron, etc, because they think its too complicated, and that the parts would be too sensitive (i.e. that they would be easily destroyed). but its not that complicated and sensitive as most people think.
it depend on peoples : i konw a lot's of people who think that software developement is harder than hardware.
its pretty much the same as it was when computers became widely available. many people were afraid to touch them, because they thought they are too fragile. today we know better, and many people built their own pc's from single components. and whats the real difference between plugging a ram stick into your pc, compared to plug a chip into some pcb? to me, not much ....
anyway, to go back to the original discution : whatever the dificulty of hardware developement, you can't say you're free if you use not-free hardware.
agreed .... ;-)
