Found the DSO 150 much better to assemble, repair & easy to operate with it's easy push buttons & rotary dial. Tried the DSO 138, assembled it, worked. for a while, repaired it, replaced the 10 uH inductor, but found 9v+ reg kept overheating. Gave up in the end to get the DSO 150 instead, which is suitable for most projects & repairs. One day hope to afford a proper scope. Using the scope for power supplies, inverter, motor control & help with learning the Arduino UNO programmer. Blind without a scope. I don't like soldering smd's.

Trigger and trigger stability is 80% of an Oscilloscope, sufficient bandwidth is another 15% the remaining features is 5%.
Tektronix became king because of their trigger circuit - don't wast your money on this crap, go buy an old 50 Tektronix on eBay - you are much better of: -)
I have owned 25+ oscilloscopes in my 45 years in electronics, I have 5 now - two is Tektronix - none of my oscilloscopes has been less than 10 years old when I'd bought them.

I bought the updated, Kuman brand of this oscilloscope kit from amazon. 40 for kit plus shell. This was the version with SMD components pre-mounted. It comes with a nice manual and includes several diagnostic/troubleshooting guides in case you get lost along the way. It was a nice project for me and the updated kit has a good layout and is pretty easy to use. As a hobbyist I'm happy with it; I don't need the 300 investment at this stage.

eh, not impressed. My Rigol paid for itself by my use in consulting. I like my 32 bit USB logic analyzer, but the key to that was it offers more bits than standalone units and displays on a standard PC. I think a USB scope might we worthwhile because of using the PC display. There was even a USB single probe PC scope that was basically the size of a probe.
By the way, there are several of these stand alone units with cases now.

Digital storage oscilloscopes are just pathetic. Never can match the charm of an analogue oscilloscope. However in the hands of novice these DSO are helpful. Really to work with their levels of lag is disgusting. DSO are just disgusting. If you are working with much lesser frequencies please think a while before putting money on the expensive DSOs. They are such a piece of scrap.

For a few dollars more, you can get a Pico Scope that connects to your laptop or pc USB port. The Pico software is excellent, and the Pico Scope itself is compact and very well behaved. Im not affiliated, just an electronics hobbyist sharing my experience with inexpensive scopes.

I have been repairing cellphones, I sometimes I need to see if some crystal are producing correct oscillation and PuMic, processor as well. But spending 25 bucks for a toy is not my cup of tea, Some of you find out this worth for cellphone repair? Can I read at least 100Mhz?

I tried connecting my mp3 music player headphone output to this cro but am not getting any reading. Just the noise you see when not connected to anything. I have the gnd connected. Why? Is the signal too low a voltage?

It's quite interesting to see, that your DIY oscilloscope did work with a frequency above 100kHz, even beyond. Because my exact same oscilloscope kit refuses to even show frequency above 20kHz.
