Digital Oscilloscope Kit with BNC-Clip Cable Probe with Power Supply, (Assembled Finished Machine) EM001

I read some of the negative reviews and I do believe them, so how can't you go wrong then? Well short of never getting your order which rarely happens, that's the only show stopper!In every other scenario there are easy fixes!I had no real issues after assembling the kit which I wouldn't hesitate to recomend to anyone. Beginners just take your time soldering. A beginner can easily get it done under an hour, more experienced people can have it done in 20 minutes.About the only thing worth mentioning is the main IC, 2206? Is not that great. I suspect it is either a counterfeit part or just made with bad quality control. The real part which would cost you more than this kit is way more stable and can operate from 3-16 volts. This part that comes with the kit is useable just not as stable. Will only work very close to 8-9 volts. Any higher or lower it becomes unstable. Also, if you find it's still too unstable, you can still make it work by replacing the 2 big caps with the same values or a bit higher vaues!There are enough youtube videos for this model and all the copycat models. All use the same schematic and parts. The videos go over all possible errors and all the easy fixes. So if a beginner does have some issues they would still be able to fix them easily.Please note you may not have any issues too! I suspect the reason for that is the lose specs in the components so you may also want to test all the caps and resistors before you solder and replace any if needed.Bottom line is you couldn't possible buy all these parts for the price of this kit. I paid $10 for mine. I'd pay up to $15 for this kit or any copycat kit. Any more then it loses the value and benefits I'm about to share with you.I said you can't go wrong and I mean it! Consider what you get for your $10. All the parts, with schematic, hard clear case and possibly the best thing is the experience and fun you get for just $10.I was going to make my own from scratch until I ran across this kit which was perfect for my needs. I wanted a light weight as small as possible portable unit. This is not intended for crucial tests. This is for quick and dirty checks on the go, but also great for students and weekend DIYers! Sure one can surely find something to complain about this $10 kit. My biggest complaint is I didn't get this kit sooner!Pictured here with my portable osiliscope.

I ordered this primarily for hobbyist HiFi bench testing projects, just to check for clipping on low level input and high level output signals, as well as to do some basic board and chip testing and troubleshooting. I wasn't expecting a precision instrument at this price but it's more than adequate and gets the job done for my needs.The first one I got I suspect was bad out of the box. With no input signal I was getting a staticky waveform and when I attached the probes it got worse and would spike when I jiggled the BNC connection. Probably a bad ground. I exchanged it for another unit and this one was better, although it never reads totally clean on boot up.If you have never used an o-scope before you will probably need to watch a YouTube to figure out how to dial in the scale and functions for your needs but once you have a basic grasp it's pretty easy to use. Definitely a must-have for the budget electronic hobbyist after a good multimeter, of course.

This is a sweet pocket scope!I added a 9.6 vdc Battery pack velcroed to the back for power, totally nice!Did have to pull it apart and repair it from a typical "remove the probes when changing from DC to A/C power analyzing" "you will let the smoke out! hahahah" - I was able to repair the trace that turned into a fuse" - and in the process admired the simple, yet effective design - thank you!

I am going to return or get a replacement because the one that I received seems defective I follow the instructions I didn't do anything wrong and it will not show up the sin wave that I need to set my amp or anything else somebody told me I needed to buy the 10 ex-probes because that's the only way that it would work for them but I don't understand because I watched several videos on this same exact product everybody else can use the same probe to come with it and the reason why you buy a product like this is that way you don't have to buy other products in order to get this product to work very dissatisfied at the moment if they send me one that actually works or can send me some kind of info to guide me into getting this thing to work then I will change my review

I have used this multiple times to set amp gains to avoid clipping and distortion. Easy to use once you know how (YouTube has videos). **Hint....get the battery adapter so you don't have to stay connected to an extension cord**

I was in a hurry when I tried to use it, so I couldn't figure out how to use it, hopefully YouTube has a tutorial , because the instructions were useless. Definitely not impressed

I got this to set amplifier gains, and head unit volumes in car audio installations. It works as intended, although I had to play with the settings for a few minutes to get the wave visible on the scope. Once I got it figured out it was great for detecting clipped signals coming from my head unit. I would recommend this for anyone looking for an accurate way to detect clipped signals in audio installations

I dropped it and that disconnected the power from the board but it just needed to be resoldered. I wish I could put 4 4/5 star because its all I needed.
