Re: DOS Shell NG gives " *** Read EEPROM failed ! "

Could be the error related to the external EEPROM (U2-24LC32A)?

In this case, you could check if it's correctly soldered to the PCB

Re: Alternative firmware to use in an analogue synth?

Just found this thread where somebody shows how he integrated a DSO 138 in a synthesizer (look for a post by sduck about the middle of the page).

Re: Li-ion power mod

Hi, How do you know when the battery is low? Has anyone made a circuit to show the battery level? A hardware approach would be to include a specific module (like this one for example), provided there's space for it in the increasingly crowded case (after including also the modules for battery charg...

Re: DSO 138 mini available for preordering!

I partially agree with you, except for the battery issue ( that can be fixed ), DSO 150 Shell appears to be better and cheaper than DSO 138 (first version or mini), leaving apart it also includes a case. The only advantage for 138 mini is that it's a bit smaller than 150, something that could be use...

Re: Alternative firmware to use in an analogue synth?

Of course, the firmware could be modified; as the source code and libraries are available, and some have done it already . There's also an open source firmware for the scope , not based on Jyetech's libraries, which could also be the base for your needs (for example, they've added support for a seco...

Re: firmware 110 problems SOLVED !!

...Of course, it would conflict with the battery mod stuff. Not necessarily, in fact, I was thinking to use a charging module without micro USB and use the +V output of the USB to serial module to feed it. Using the appropriate modules, there is enough space to include the USB to serial, the chargi...

Re: firmware 110 problems SOLVED !!

...and the module 3.3V power output would be connected to JP1 (but not to the scope 3.3V rail). That would bring JP1 high when the USB cable is connected, and put the processor into flashing mode. Good idea!, but if you want to use the serial port also for downloading captured data (as it's possibl...

I've seen today it already has a product page at jyetech.com.

It says "The scope can run on USB or a single cell 3.7V Li-ion battery which make it much more convenient as a portable device"

Re: Li-ion power mod

... I dont' understand why you had to change the charge/booster. In my opinion to avoid quiescent current to drain the battery when not in use it's enough to switch the battery...

DSO 138 mini available for preordering!

Banggood has the new version of DSO138 available for preordering! Shipping would be on Dec 15th or later. Jye1 had already announced this new version was going to be released soon in several posts (e.g., this one ), but it doesn't still appear at jyetech.com . From the photos, it's design follows th...
