The Jye Tech DSO-150 is a capable compact scope that you can purchase as a kit. If you’re really feeling the DIY ethos, you can go even further, too, and kit your scope out with the latest open source firmware.
The Open-DSO-150 firmware is a complete rewrite from the ground up, and packs the scope with lots of neat features. You get one analog or three digital channels, and triggers are configurable for rising, falling, or both edges on all signals. There is also a voltmeter mode, serial data dump feature, and a signal statistics display for broader analysis.
For the full list of features, just head over to the GitHub page. If you’re planning to install it on your own DSO-150, you can build the firmware in the free STM32 version of Atollic trueSTUDIO.
If you’re interested in the Jye Tech DSO-150 as it comes from the factory, we’ve published our very own review, too. Meanwhile, if you’re cooking up your own scope hacks, don’t hesitate to let us know!
Thanks to [John] for the tip!
Looks impressive. Nice to see work is being done on this thing. (I see it’s forked from a DSO138 variant)
I also bought one of these (and a DSO138 too). (I also have a Siglent SDS1104X-E)
I see it already has some extra functions: digital inputs, Serial? bit numbers for voltage measurement.
Also looks like the triggering is improved. That is especially nice because that was one of the biggest limitations of the DSO 138/150. (Also bandwidth of course, but it’s on par with the price point of these things). Out of the box, noise level of the DSO 138/150 is also quite bad. Now that there is full open source software (note: JYE tech has partially open sourced their code, combined with some pre-compiled libraries) I may have a go at looking deeper into this.
The prices of the DSO138 and DSO150 are so low that these can be used as generic development kits for anything with an STM32 and a TFT, even if you don’t want a scope. Having fully Open Source software available is another step up for getting any project going on these things. Especially getting the LCD working.
Also note the chinese are working hard to be independent from “western” markets. I bought two Kingst LA2016 Logic analyzers. My older one has a Cypress uC and an Altera FPGA, in the newer variant both of these IC’s have been replaced by chinese clones.
Some nice ideas for extensions:
* Coupling multiple of these things and synchronizing their sampling to get a multi channel device.
* Adding a Flash chip and use it for data logging.
* Battery powered for use in area’s where there is no mains.
Not that I knew about this firmware. But “latest open source firmware” kinda sounds different when you notice that the last commit on the github is 5 years old…
