JYETech 'DSO Shell' Oscilloscope DIY Kit w/Enclosure, 100MHz Probe, Clip Probe & ESD-Safe Silicone Mat

I purchased the DIY version of this kit on Amazon from NooElec Inc.on 16 Apr 2018. It arrived plenty quickly. I purchased the version of this JYETech DSO Shell O-Scope kit that did already have the SMD components soldered on, but that needed the regular components: resistors, caps, pots, headers -soldered on. I completed soldering the components in to the board last night, then Itested voltages as per the included JYETech docs and & web page. I also performed their manuf. recommended, internally-supplied test signal calibrations, using the two trim caps. I hadn't soldered any electronic components in quite a while, so I had to go purchase lead free, rosin-core solder from my local H/W store, yesterday evening. I did pre-meter-out all of the solder-able components that I had the capability to measure, before I inserted these in the circuit board and soldered them into place the circuit boards that are included with this kit. My kit came with the 2nd-to-latest FW rev., #113-15001-111 - which rev. is listed on the JYETech online support pages, pre-loaded on it when it arrived from Amazon. Perhaps, that is the latest F/W rev. that is fully compatible with the circuit board rev. that I purchased and received, I just am not quite sure about that yet. I did not read up on the firmware revs on the JYETech support pages until after I had my kit fully assembled and also failed to remember to take photos of the boards that might now help me pin down what rev. board I actually received, but have not yet emailed JYETech support to with a screenshot of my boot screen to get clarification on this point of which board I actually received and which FW revs would thus be compatible with that.This kit just worked, right out of the box and once I got it fully assembled. I am pretty much lovin' this pocket O-scope for, just, under $40. I have not yet had time to attach or calibrate the 100 Mhz Probe that also came with this kit. I have only had time, so far, to perform tests using the the manufacturer-supplied clip probe . This is partly because I also had to a solder-up and assemble an entry-level KKmoon function generator kt that I also ordered up from Amazon for use with this O-scope kit.Specifically, I purchased the KKmoon XR2206 High Precision Function Signal Generator kit for use with this little beauty of an O-scope. I love that I can power this O-scope with a 9V battery! I am still dustin' off the mental cob-webs as regards effectively using O-scopes, from my Salad Days on the tech repair bench during the Golden ol' 1990s.Kit Pros:It worked well right out of the box and can easily be battery powered.It's a $40!, pocket o-scope that has a working (auto)Measurements feature that you can toggle on or off at will.This kit has great Manuf. specs for price. And.. those are still under review/my own test and confirmation efforts: 0-200Mhz range, 12 bits res. and input power is 8-(be careful to keep input power supply under - no more than)10v [a 9V supply is what the manuf. recommends].Cons:For a $40 kit that does all this, really, cons?That said, its a single channel scope that has a pretty small, but quite readable, color display screen.Additional thoughts (that aren't necessarily Pros or Cons):You need JYETech's own model 119 UART to USB Converter, or a third-party model and some free S/W from ST to be able install future manuf. fixes and improvements via upgraded Firmware releases from JYETech,. There are also, apparently, multiple revisions of the board and different firmware revs are, I believe, specifically targeted for use with different board revs... However, JYETech appears to have been offering this O-scope kit, and more than a few other models - including a dual-input channel, portable model, for some time. I was reassured to see, via the well-documented content of their support pages, that the folks at JYETech are obviously, at least so far, keeping this unit relevant and well-tuned by offering up fairly regular firmware updates that provide the end user community with ongoing hardware fixes and functional improvements. I found the signs that they are able to continue to offer all that, at this price point, quite encouraging. Here's a big "Boo-yah" to the JYETech folks for their obvious, ongoing commitment to their fantastic products. FYI, I did email one of the registered sellers listed on their product pages with a technical operations question on Saturday night MDT. I received a helpful response email back from JYETech in just under 28 hours. They answered my question clearly.Disclosures: At this point I just ordered this O-Scope up an Amazon and gave it a try, pretty much on a lark and after a technically heavy weight friend had advised that it looked like it might be a pretty good kit. I purchased this O-scope kit with my own hard-earned USD and with no promotional considerations, of any kind from anybody, including: JYETech, the Seller, Amazon or anyone else. I would imagine that, at least a few, readers of this review might like to know that.This is my first-ever exposure to the JYETech kits and/or hardware. I am really hoping that I did not just get lucky with this great buying experience. However, if the JYETech product and support web pages, and responsive customer support team, provide one with any kind of a reasonable indicator, then I would have to guess that I probably had a pretty normal purchasing experience with my first-ever JYETech product.Additional information may follow, later, regarding my evolving impressions over time with this O-Scope kit, if/when I can find the time to post them.Here are links to the KKmoon Signal Generator Kit and to the Wall Charger that I purchased with used with this O-Scope. [FWIW - That Wall Charger worked perfectly fine for me, up and until I found my 9V battery cap leads and d.c. plug/barrel connector, the one with the nice screw terminal posts. I was able to use those parts with a cheap-o 9V battery that I had laying around, from the Dollar Store, to reliably power this O-scope. At least one of the attached photos shows that kluge-er-ific rig in action, along with capture of the (Auto)Measurements display.]:9V 1.5A AC/DC Power Adapter for Arduino, Tbuymax UL Listed Center Positive 5.5mm x 2.1mm Power Supply Cord for UNO R3 / Elegoo UNO R3 / IEIK UNO R3 / MEGA 2560 R3 (6.6 Ft)KKmoon XR2206 High Precision Function Signal Generator DIY Kit Sine/Triangle/Square Output 1Hz-1MHz Adjustable Frequency Amplitude

I liked that the oscilloscope was easy to assemble and the cost was low. It functions well on monitoring automotive sensors. I would have preferred either a rechargeable battery or that the case would contain the battery.

This handy little low cost scope works well. The encoder based adjustments are quick and intuitive. Instructions are adequate for assembly and startup, no problems encountered. But the 9 volt DC power requirement is a bit oddball. So I bought a little boost converter board MT3608 for one dollar to add inside. I soldered in pi-LC-filters for 5V in and 9 V out , wrapped it all in tape and copper foil ground, and glued a micro USB 5V connector on the main board. Now I can run the scope from a little 5V USB port Li Ion powerpak for portable use , perfectly ground isolated - and it gave NO added signal noise. Hope JYETech will one day go for std USB / 5V input... and why not also expand it for easier data transfer to PC ! And final comment - This small device has a big advantage ove my PC USB scopes: It works very quickly after power up and shows data on the spot, just like your little digital volt/ohm/mA meter. And with a battery on its back, and my home made short light test leads with mini clips, perfectly ground isolated and minimum of dangling cables. Just wish it had option for USB data save /analysis to PC.

I received this kit, and was able to assemble it in a day. I'm an experienced electronics technician and have assembled a lot of electronics kits and built a lot of circuits from scratch before. The assemble went smoothly. A big aid is that all Surface Mounted Technology (SMT) parts were already assembled on the two boards.I was able to power up the oscilloscope as I was assembling it, and everything worked fine. However, if I screwed down the front 'frame' (around the front panel), I get an '0x9341' error on the second start-up screen and the unit freezes. When the front frame is removed, it works correctly. Because it works correctly when unfastened, I don't think I made any errors in assembling the kit.I tried to post this error to the Manufacturer's (JYETech) forum a week ago, with no responses. I wrote directly to JYETech 5 days ago, with no response. I contacted the seller, Nooelec, yesterday, more than 24 hours ago, without response so far.My advice is to buy one of the assembled versions of this exact same pocket oscilloscope. They're about the same cost, if not less (I thought it would be fun to assemble the kit). Then, if there's a problem, there can be no doubt who's problem it is.I'll update this review if there's any change in the status of my kit.-Kevin

For $40, I can't complain much. It was easy to assemble, following the directions. Works as described. I really like the rotary encoder compared to the "push button only" interface of similar devices. The only draw back is the lack of a battery. I ended up mounting a panel mount 9V connector to the bottom of the case so when I use it, there is a 9V battery sticking out of the bottom. It was $40, though, so who really cares.

Simple enough construction but not for the absolute beginner. Soldering experience needed, which comes with the understanding of how heat affects certain areas. Instructions are graphically helpful. But the PCB legend was barely legible on my circuit board. However all that said. It's a great little hand held portable DSO oscilloscope. I use my on my car frequently and am glad I bought it. It was thoughtful of the seller to include the probe and static free building matt. I'm free to use the $10 Matt on other projects now and the probe is much easier to use than the clips. It would help if the battery pack had an attachment point. I'll use my 3D printer to print a small battery case to attach it later. Overall it's a neat unit and very capable of handling many different electrical repair jobs like TV's car stereos, shortwave even many smaller tasks.

This is a great little educational project to build and operate.

Chiaramente ottimo limitatamente all'uso hobbistico, facile da montare e da settare, originale al 100%.

Consejo: realizar la comprobación de la placa digital antes de que finalice el periodo de devolución. En mi caso, por temas de tiempo, no he podido ponerme con el kit hasta varios meses después de comprarlo. Al realizar la comprobación inicial de la placa digital (con una fuente de 9V - comprobado que no excedía los 10 V - y con la polaridad correcta) el regulador LM1117 empezó a humear inmediatamente. Resultado: placa arruinada - es posible que pueda ser reparable cambiando el regulador, pero al ser un componente SMD no es nada sencillo de reemplazar.

If you have basic resister/capacitor soldering skills you should have no problem building this in a few hours. The instructions are very clearly written and lots of pictures to help you get it right. Mistakes can be made if you are not careful, like populating the wrong side of the board so take note of the warnings and you will avoid some of the issues I see in the negative reviews. The finished oscilloscope works well with many features that make it a useful tool. Of course for this money you are not going to have high-end, high frequency performance, I use it for checking things like the 32KHz BIOS clocks on PC motherboards, a job it does perfectly.
