Digital Logic
Split an analog signal to two independent inputs. Utilize UPL 6.003. Use unity gains.

Signal Conditioning
Digital area state sensor, (microwave) open/off/used.... Other application for contact tracing. Like a proximity mine, non_reset

Using parts from the UPL, based around the ATMEGA32A-PU (UPL 9.003), design a 3 axis 3D printer controller. Allow for extruder controller, and 3 end stops. Design around Pololu plug and play motor controllers (not on UPL)

3D Printing
Based around one of the ATMega chips from the UPL. Control a VGA screen at 800x600px, display standard ASCII characters. Allow the system to be communicated to by UART (or potentially I2C). This can essentially act as a "graphics card" for other ATMega projects. The idea could be expanded to an "Arduino game console"

Audio Visual
A small desktop device that can convert various sound inputs (Be it MIDI, XLR, or a 6.5mm Plug) to a digital signal for interfacing with computer for things like editing in a Digital Audio Workstation such as "Audacity" Hopefully Studio/Audiophile Sound Quality. It should use USB type C or Thunderbolt 3 for computer connectivity. End product should be something like this: http://www.pssl.com/Behringer-UMC-404HD-192k-4-Ch-USB-Audio-Interface or this: https://www.bhphotovideo.com/c/product/1251655-REG/focusrite_scarlett_2i2_2nd_gen_scarlett_2i2_usb_audio.html

Using noise on an ADC pin, incrementing some algorithm, create a random number generator that is addressable via I2C. This can likely be done with an ATTINY85-20PU (UPL 9.001) and an antenna trace. Break out via header pins.

Equivalent of https://www.harborfreight.com/90-amp-flux-welder-61849.html - for light duty MIG Welder applications. Though this is called MIG becuase it has a spool and gun - this does not have shielding gas but only flux core wire.

Using a 555 timer (UPL 7.001), generate a square wave who's frequency is determined by a capacitance placed across two terminals. This can be used for capacitive sensing applications.
