Podcast Notes

  • This podcast was recorded at the MacroFab Engineering location. See Figure 1.
  • MacroFab had its annual Thanksgiving Potluck today. See Figure 2.
  • Parker has been working more on the Jeep Radio. Part numbers for the IC’s are the following:
    • TDA8563 : 2-Channel 40W power amp
    • TDA7429L : ST manufactured 3 Band Equalizer Audio Processor
    • TEA0675 : Dual Dolby IC
  • Stephen brewed another beer with his electronic brewing rig. He has updated it to be safer and less likely to kill him. See Figure 3.
  • The FX Dev Board is nearing launch of the crowd funding. Video is almost done.
  • The synth Stephen has been working on has the VCO (Voltage Controlled Oscillator) designed and layed out.
  • Open-V, The First Open Source RISC-V Microcontroller. Students at the Universidad Industrial de Santander in Colombia, have been working on an open 32-bit microcontroller based on the RISC-V instruction set. It is being crowd funded on Crowd Supply. $49 USD gets you a first-run mRISC-V in a QFN-32 package and $99 gets you a development board with a SD card slot, USB connector, and voltage regulators.
    • 160Mhz Clock Speed
    • SPI
    • I2C
    • SDIO
    • JTAG
    • 10 Bit ADC
    • 12 Bit DAC
    • 16 GPIO
