Whatever we do, encephalograph, an ECG, a myogram or something like that, or simply copying other people's devices.. to view the signal without recorder will not do! oscillographs not do - it can only show the same shape and frequency of pulses. in other cases, it will be "garbage".
have a funny pattern. on one device (or two, if you fear for your comp).
no microcontrollers! all molded to the LPT port.
but there are two problems: the presence of the port on the PC and mikruhi in stores )
I haven't taken the case, try first to solve these two problems

the recorder for our experiments.

Yes, I know these shemki, but here, few people will be wrapped mikrikov, well, if all that would gather.
and modern digital ostilly also able in this mode to work

Most interesting is that this scheme can never collect.Экко wrote:but there are few who will mikrikov wrapped, well if all that would gather.
Here HERE can be ordered already assembled version (the place has been repeatedly tested).
But if you have to pay a little more then you think and the controller will flash (firmware and the value of the fuses I have).
Total everything will cost $10-15 and nothing to solder no need.

to collect it is not a problem. and to flash programmer needed. for different microcontrollers your programmer to do

LPTScope on VB is written, if you find the source then all is fine. and in VB do not understand, do not respect themselvesАлега wrote:Gather-gather.You just make a working circuit,and the software would not prevent travel.
