Pwede ang POT sa position but this will be placed on the hardware side, adjusting the DC offset (virtual gnd) of the opamp.

yes sir isa sa mga yan

pero baka hndi nasimple ang kalabasan

True.
I was even planning to make the interface just 2-3 buttons para mas simple ang construction.
Wala na lang time. Yung power meter ni Rafft pa nga hindi ko pa na-tanggal ang bugs sa new version.
Review mode pa.

a mini DEMO of that scope.. pasensya sa lousy function gen... was thinking of hooking up the input to the PC soundcard and use "function gen app" para PERFECT ang output waveform, kaso wala ako available stereo plug ngayun...

mini DEMO 3310 LCD scope

Woots29 · « **Reply #86 on:** December 21, 2009, 04:49:39 PM »

waw galing sis rafft rafft

baka pwedeng lagyan ng hold

RaffT · « **Reply #87 on:** December 21, 2009, 05:00:41 PM »

may hold naman talaga yan.. hehe nakalimutan ko lang i-demo.. most of the "control" was done sa function generator... dalawang "function" lang ginalaw ko sa scope, yung us/Div at freq switch...

bad nga lang ang output kasi "maingay" yung function gen ko. If it where from PC yung signal, eh gayang-gaya talaga yung waveform from PC to lcdscope.. kaso namissplace ko yung stereo plug ko

insomartin · « **Reply #88 on:** December 21, 2009, 06:05:22 PM »

parang nakakatakot gamitin... feeling ko nag cliclip yung signal kapag sinicenter.!

sana wala na yung line sa taas and baba. kasi perception ko talaga clipping yung signal. noobie.

ok na ito kesa WALA.. hehe at least the MOST important part dito is yung TRIGGER function, kung wala nyan, eh "jerky" ang waveform.. just like when the LED is blinking, meaning hindi siya nati-trigger

RaffT · « **Reply #90 on:** December 22, 2009, 03:48:11 PM »

ok eto na ulit!

another DEMO, now using PC+soundcard and wavetool software.. for use as function gen...
hindi pala 2KHz max na pwede makita ng scope, yung demo eh 1KHz na yun

3310 lcdscope Demo 2

EDIT:
====
anak ng .... eh lalo pa pumangit ang vid quality dahil sa transcoding.. arrrrrrr

zer0w1ng · « **Reply #91 on:** December 22, 2009, 08:08:43 PM »

The clipping of the signal is due to the input which reaches the ADC max level (5V or 0V). When this is reached the diodes inside the ADC input clips the signal and the reading will be still 0 or 255 thus the clipped waveform is shown.

insomartin · « **Reply #92 on:** December 22, 2009, 09:48:28 PM »

the bad clipping is from the function gen in the first video. the clipping on the 2nd video is good (not showing).

Ah..I thought that it was due to the levels over the range.

galing ha

tony · « **Reply #95 on:** January 06, 2010, 08:13:09 AM »

ang galing mo rafft....sana madevelop mo yan sa mas malaking lcd screen or as attachment to desktops or laptops...kuha ako ng kit if ever.....

Woots29 · « **Reply #96 on:** January 13, 2010, 06:58:31 AM »

or LCD ng sirang portable DVD

(sayang kasi mga datasheet nun eh intsik tsk

)

Tanong lang po san po ba pwede gamitin tong osilloscope na to. Pano po ung program nito! Pwede po bang ang monitor ng tv ang pwedeng gawing monitor ng oscilloscope! HEhe

zer0w1ng · « **Reply #98 on:** February 05, 2010, 02:03:58 PM »

TV video signals are fast. Hindi ito pwede.
Audio signals, AC lines or few kilohertz signals lang ang kaya nito.

travian19 · « **Reply #99 on:** February 07, 2010, 10:47:41 AM »

pwede pong makuha ung ginamit ung software sa pagbabago ng program nito!
