DSO138 Digital Oscilloscope Kit step by step build

[@oscarjosefsson9300]

From what I can tell, a good video. It is nice that you show how you actually do it and give som tips on how to handle and identify the components! Some other channels shows assembly with a time laps so you don't really see anything meaningful at all...

Very clear and instructional, thank you. I believe the kit can be obtained with all the SMDs in place, which should make assembly even easier. It looks a very useful project for a novice enthusiast.

[@robojax]

You are welcome. I did not know if we could get the kit with SMD components in place. Thanks

Helpful watching before attempting. Thanks for explaining how to decode / interpret the labels of various components.

Good vedio from Sri Lanka I also going to buy this kid

Good video. I was having issues with those 2 caps that my tester wouldn't read. After putting them under the microscope I decided the 3 dots was a 3 so the smudge must be a 1.

Soooo… this is now my second soldering project. First one was a little clock. 😂 I had some confusion regarding bad readings from my multimeters and accidentally placed one of my 470 ohm resistors in place of the choke, probably trying to get ahead of myself. 🤦🏽‍♂️ While desoldering, I broke the lead RIGHT where it meets the body. Luckily I found the tiny effers with a magnetic sweep. Now to the point, the node in question is R40… that is where the resistor should have been so I soldered the broken pieces to that spot. After soldering the base, I put a bit of solder at the broken joint… will this work? Long winded, excuse me! Kids runnin around everywhere and YES I’ve had a couple drinks! 😂

Not letting me add a pic for whatever reason…

thanks a lot!!!

[@robojax]

You are welcome.

Why does Robojax.com keep popping onto the screen? It's not necessary. You have made a very nice, honest & clear instruction set here but it's made difficult to follow with the silly unnecessary pop up:(

[@robojax]

Thank you for pointing this. We were selling products online and had store. I will remove it immediately from now on from any video that is recorded.

[@untrust2033]

It's to stop people getting away with stealing it. It doesn't get in the way

[@jsngallery]

what temperature do you have the iron set at? tks

[@robojax]

I can't set the tempearature on my soldering iron. Just 30W or 40W soldering iron will work fine.

Its funny withe the transistors I was trying to find the data sheet for the pinout but couldnt find it. I should of just looked at the well laid out silk screen :p

[@robojax]

😊

[@livestefan]

I have the same kit, but as a clone. I can't get it working, the lcd backlight turns on, but nothing else. If i check r4 and r2 on the board, i get both readings as 1 megaohm instead of 2 megaohms and 1.8 megaohms, respectively, any help is welcome

[@DrSlick]

Did you ground yourself before touching all the boards?

[@livestefan]

it was a bad capacitor after all lmao. Im looking at the date of my comment and seeing it was 1 year ago made me feel old@@DrSlick

[@tonywright8294]

Smoothie voice excellent

[@samuelquartey4019]

what is the max voltage?

[@robojax]

Under the video in the description there is a link to resources for this video where you see many files including user manual which has all information. here is the link to make it easy for you robojax.com/L/?id=242

[@DrSlick]

Maybe ground yourself before touching the boards.

good to do, but , not always necessary. in high humidity areas, you dont need to. +45 years experience in electronics
