Hi! I am a 24 year old experimenter from sweden that have been doing electronics since i were 6 year old.
Oscilloscopes are a great too to have around the lab for checking signals for abnormalities, i used to have a Tektronix 2445B 200MHz analog scope but its been broken for some time now, then i thought: hey i have that old broken 10MHz scope just laying around, maybe i could do something with it.
Said and done, i decided to try and build a scope from scrath, maybe i´d learn something in the process.
This is the progress after about a week of work:
That's a lot of wires but a cool project non the less
I hope it comes together well for you.
The only issue I have is the viewing panel without the grid divisions. How do you know the period and amplitude of your waveform?
I just wanna see what waveforms look like. But the grid is typically in centimeters so if i wanned to i could make a grid outta some plexiglass and calibrate the input for xV/div and so on.
This is a work in progress and may take several years to finish.
hm reminds me of a similar scope my dad built from a kit long ago, it still sort of works but the screen displays a bit topsiturvy, probably needs a few parts changing like caps
A little update. Yesterday i designed a triggered sweep generator with trig holdoff.
Schematic:
The holdoff works by strobing pin 6 on the LM311 as per datasheet suggestion.
Eww digital. Why would i get inspiration from that ? I cannot program FPGA's, or any mcu for that matter.
