| After I developed and published a Transistor Curvetracer based on the Arduino NANO R3 a few years ago, I analyzed the datasheet for the Ardu...
| Here I test the current-source with 12-bit DACs from Microchip. At first I tested the I2C DAC MCP4725, but the result was not so good: 3 to...
| Analysez les caractéristiques des semi-conducteurs à l’aide d’un traceur de courbes DIY compact, basé sur un Raspberry Pi Pico et un écran t...
| Built a compact curve tracer with the Raspberry Pi Pico, ILI9341 touchscreen, and a custom power board — supports bipolar transistors (npn/p...
| I use from the HC595 shift-register the first 5 bits as DAC and the three other for changing Uref from 2V to 800mV, changing from current to...
| In some of my projects, I use the Raspberry PICO (RP2040 or RP2350) with the TFT_SPI color display ILI9341 or ILI9488 / ST7735. They are ch...
