Notepad with an oscilloscope and a frequency generator (sound card)

I decided to write a little about my craft. Several times came across a variety of diy line. I wanted to make myself something similar, multifunctional. The form factor of the line was not very suitable for me, I decided to make it in the form of a notebook.



In addition to a more or less standard content



(centimeter ruler, footprints for many popular elements, output sizes), the frequency



converter (sound card) on the PCM2706 was added to the DAC by the DAC according to the manual for the microcircuit. I



also added a card laboratory from the project from the chip website to the board dip based on the microcontroller STM32F042F6P6

the details

Capabilities:

1. 3-channel oscilloscope with input voltage range 0 - 20 V,
   maximum sampling frequency 282 kHz - 800 kHz
2. logic level analyzer
   input voltage range: 0 - 20 V
3. notebook (maximum number of characters: 4000)
4. "Proverbial" chains
5. device check 1-Wire
   device code
   display current value display (temperature sensor)
6. LED test
   universal footprint for 2-pin smd and dip housings

To connect additional devices on the board made a mock area. SMD adapter chips. Calendar (added to fill in some empty space). File with the board, insta

Conclusion:

You can argue about the real practical benefits, but I just liked how it looks. An interesting thing, but probably more suitable as a souvenir.
