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

Signal Conditioning
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.

Create a 1 bit alu slice, capable of: Increment, Decrement, Shift Up, Shift Down, And, Or, NAND. Use UPL digital logic chips.

Digital Logic
A battery charger that takes in the input which is DC (12v) or AC (120 or 240v), and uses it to charge one or more batteries in a vehicle such as an E-Bike, or a Velomobile. There are many existing models with the AC inputs, but the DC would be unique, and add to chances of adoption. The DC input is for removing the inverter losses if one were to use a DC Generator, a Fuel Cell, or Solar Panels, to power and/or recharge their vehicle. Output should be a XT-30, a XT-60, and a XT-90 dc connector. Mild Weatherproofing ins a nice to have.
