content: I built JYETech's DSO150 "Shell" scope kit a couple years ago, and have found it to be very useful. Now JYETech has released a new 2-channel scope, both kit and asssembled, called the "Wave2". It's more advanced than the Shell, with X-Y display, a function generator, and external triggering. It also has a touch screen and two real scope probes. And it's a good bit more expensive than the Shell. JYETech sells the kit without a battery for US$79 and the assembled unit with battery for US$93, with free shipping in both cases. Here's the Wave2 page on their website with all the specs, manuals and schematics.https://jyetech.com/wave2-2-channel-oscilloscope/I've exchanged emails with JYETech about the Wave2, and my understanding is that the Wave2 is generally in the same speed class as the Shell, but more capable, with more features and easier to use, and of course two channels instead of one. The touch screen is resistive, so will probably work better with a stylus or similar hard-tipped instrument. The firmware will be updatable as it was on the Shell, and history demonstrates that JYETech is quite willing to update when needed.Based on my experience with the Shell, I think this should be a well-engineered, well-documented product. Of course you won't be doing microwave work with this type of scope, but my Shell has turned out to be surprisingly useful for things like steppers, servos, and various signalling patterns, and in many cases you just need to know whether there is activity on a line. But I've always missed that second channel.Now I need to say something about the battery. I converted my Shell to battery power, and I can guarantee you that people who buy the Wave2 will want it to be battery powered. But the shipping regulations on individual LIPO batteries are really strange. JYETech tells me that they can ship the assembled unit with a battery included for a reasonable price, but shipping the kit with a separate battery is far more expensive, and they would need to charge $30 shipping for that. Well, of course nobody is going to pay that when they sell the assembled unit, with battery, for $14 more than the kit alone. So if you want the kit, and a battery, the best option appears to be to order the battery separately from Ebay or AliExpress from sellers who appear to have a way around the regs - about $9. Everything else needed for battery power is included in the kit, including the charger module, the boost converter and the connector.And finally, there is what I think is the big mystery here, which is Banggood. Banggood sells the Wave2, and their price for the kit without battery is currently US$91.99. That makes no sense to me. They always sold the Shell for substantially less than JYETech's price. So I don't know what's going on there. In any case, the best price right now appears to be from the manufacturer. If you go to the very bottom of the linked page, you'll see a "Buy Online" button. That will take you to AccuDIY.com, which is JYETech's fulfillment site. They appear to take PayPal and GooglePay.That's what I know at the moment.

content: I saw that on their website for a couple weeks now. The only thing is even the calibration square wave generator on the Shell if extremely noisy when you hook it up to a real scope to view it (and that's with a ultra low ripple linear power supply), so I question how useful their AWG will be. At that price point, they are open to more competition from their local market which has higher bandwidth. No sure if I will go with it as a toy project.

content: Got one of these recently on Aliexpress. The kit was ~41 euro and the extension board for getting to the output of the signal generator was ~5 euro. Also managed to find a battery at Aliexpress for only 2,75 euro, so overall not to expensive. I find the screen to be restless and when you make adjustments it flickers quite a bit. As a toy it is ok, and maybe fun to make own firmware for it.

content: The only source I'm sure has genuine product is Banggood. Not saying others don't, but there have been counterfeits/clones on their other products in the past.I've used both the DSO150 and the Wave2, and find them to be surprisingly useful. I've used them to decode IR remotes, to check for output to servos and steppers, and recently posted Wave2 captures on the Arduino forum about the current drawn in the various sleep modes. I converted the DSO150 to battery power, and the assembled Wave2 is battery-powered, and it's really convenient sometimes to have a scope that isn't referenced to anything. If you want to see the voltage drop across a high-side mosfet switch, you can do that directly.There's another thread somewhere on here about "10MHz" single-channel scopes at about US$70, and Dave has done a video on one of them. So there seems to be a lot of choices for this kind of scope. The DSO150 and Wave2 use the ADC in the processor, so they are limited in what they can do. Others use a separate ADC chip, and can go faster. I just think hobby guys who don't want, or need, to spend hundreds on a real scope can now get basic scope functionality at a pretty low cost.

content: The one I got has a JYETech print on the back, but that can be fake of coarse. On the startup display it shows the version number of the JYETech latest, but is also no assurance it is the real thing. It works though and it is ok for testing signals coming from arduino a likes and stm32 mcu's. That is what I bought it for. Was a bit disappointed with flicker of the screen and it being quite small, so bought a FNIRSI 1013D, which is nicer, but unfortunately it has a defect with the touch screen. For the real deal I have an "old" yokogawa DL9705L which is overkill but very useful for the more complex projects. Just not that easy to slep around
