sir, ano po specs nung Oscilloscope nyo?
ang totoo, di ko pa sya tapos..  :(
pero alam ko na mga limitations nya..
like screen resolution, 97x65 lang ang resolution ng nokia 3530/3510i LCD..
saka yung ADC module ng pic ko (kung tama computation ko) 500kHz lang sampling frequency ko,
compared sa mga typical na scope na 300MHz bandwidth 2.5GSamples/s..  :(
kaya hanggang audio freq. lang kaya nya..

ang next na mas magandang nokia colored LCD is yung sa 6610/6610i..
meron na rin nakapag-interface nito sa ibang forums, kaya malamang available na ang library para dito..
aside from mas mataas resolution nya, meron na rin syang backlights,  ;D
saka mas maganda yung connector nya kaya walang worries na baka masira yung mga pads sa LCD..  ;D
yun nga lang, mas mahal ito.. dati may nagbebenta sa tipidcp.com, 1k daw!  >:(
siguro, 500 pesos sya sa mga cellphone repair shop..  ???

ang mahal lang talaga is yung LCD (and also yung controller),
the rest pwedeng kahuyin na lang sa mga lumang projects..

first, the price of commercial oscilloscopes are high...yung mura, karamihan mababang frequency lang ang kaya, especially the PC Sound Card Based ones...

second, and the most of important of all, the satisfaction you get when you designed and made your own oscilloscope...might not be comparable to commercial scopes, but it's your pride... ;D

if you have a good knowledge of CPLD/FPGA, and have some chips lying around (CPLD/FPGA and some SRAM or Buffer), you can actually make a PC USB Based scope similar to Bitscope's...100MS/s would be doable...

i did a bom cost study on fpga/cpld-based scopes but from a practical point of view it would be best to just buy the low-end variants.
