DIY digital 2ch oscilloscope

[insonicbloom]

that is pretty cool but the whole "design belongs to the university" thing bugged me a bit. when my university asked me to sign over my design I told them to fuck off.

very very nice!!! 6 people are idiots! good work!

[biketronic]

where did you buy the LCD? seems very cheap

[keoni29]

Oscilloscope in a cardboard box :D You're my hero!

[tejonBiker]

Good day, I searched for the TDA8703, in mouser electronics says "chip obsolete" :( any remplacement?

[Shaunakde]

Hi,

I am looking for good ADC modules for an ECG project. Any recommendation?

[Schmiki24]

Shoebox-scope ftw! :D

[spaceghostone]

Looks great, but what good is it if you cannot share the info with other people so they can build one too????????

[mrsteve1968]

Awsome scope, keep up the good work, dont listen to negative people......

[nanu3456]

:X:X

[cypher0147]

DUDE YOU CAN BUILT SO BIUTIFULL THINKS GIVE IT A LOVELY CASE IT LOOKS LIKE SHIIIIIIII.......

[ivanov3000mltk]

Very good job! Can you explain some points, please. As you say, you use ADC (TDA8703) with 40 MHz rate and SAM7 - on what frequency is data transfer made between SAM7 and ADC? and what you use as oscillating generator for ADC? May be you can publish scheme and datasheet on your job? Thanks.

[4sineweaver2]

Well, UoG rocks!

[DaniloDetoner]

olá amigo , você poderia me passar o site com o esquema do projeto ? obrigado

[laserflight]

actually making as osi urself is not to save money, but just the experience of building one, the knowledge gained with it and the feeling when u capture something with it is lasting..

nothing beats that feeling :)

super work guys..

[luisgarciaalanis]

What is the Max voltage it can handle in the input signal?

[NerdForMIT]

Nice scope. Yea I like the cardboard prototype as well.

[VynnKrail]

Świetna robota ;)

[hellsmaw84]

slap it in a steel case and proper silk screening and it will be perfect!

[flick2040]

also, does anybody know what song that solo is from, it's familiar and it's killing me to not know..

Radiohead - Hunting Bears

[flick2040]

awesome! I bet that was a great experience to build.

[tioz01]

I know u said the design belongs to the uni, but I really want to know how much a home made one costs. Is it possible for you to share that info? Don't need details, just final price tag would be enough.

[franekkafka]

It was ~1100PLN which is 333$ by the recent exchange rate.You could cut down cost if you didn't buy the FPGA(170PLN) and ARM(100PLN) chip ready on small PCBs and make all the PCBs at home.The LCD was ~150PLN.OpAmps for higher freq.are expensive too.

The important thing is:do you want to build an oscilloscope yourself.Aside all work you have to put in it,you don't get a device as reliable as commercial ones which have big budgets for dev.and are made by people with knowledge and experience

[tioz01]

Thank you, final price tag does seem a bit high for the bandwidth. Guess it's time to go back to ebay :(

[taimooribhatti]

Now, this is good advice!

[enginuitor]

Lovin' the cardboard prototypes :-)

[Alu10000]

AMAZING

[mateszabolcs]

Ohhh... that's beautyful... :)

[pinguinociccione]

WOW WOW WOW!!!

which microcontroller is used?

arm? avr?

very very coool!!

[LeoDJ1992]

Do you have the schematics?
