Created and placed a two-piece gray PETG enclosure with separate, toggleable Enclosure Base and Enclosure Lid models. It uses top-access M4 screws threading into plastic bosses, with no bottom bolts or exposed bottom fasteners.
Open items
  • Physically trial-fit the J1 and SW2 openings before final printing.
  • The modeled 3.2 mm M4 pilot bore should be tuned for the selected self-tapping screw and printer calibration.

Image Extraction Notes — GZ-TU-REV2_sch.png
Behind the Design
I wanted to start with something basic, proven, and easy. I also wanted to make this a realistic scenario for Flux users, which is why I based this design off an image. This way, the agent is used and reads the schematic to then create all library components.
The unviersal alarm starte as lab project during college, but soon expanded into a small product by itself. It has a battery, charger, SMT and TH components, a switch, a connector, FETs, LEDs, a Buzzer, and ICs It really is an all inclusive bundle merged into a simple to understand design.
A single cell lipo battery runs the show, a touch sensor triggers a strobe & buzzer once the device is agitated. The frequency of the strobe & buzzer are determined by a 555 Timer for 1sec ON, and 1sec OFF. A 555 Timer is also used as the trigger circuit, which show cases an alternate use for a common IC.
Putting it all together is also fun, with basic mounting holes a user can 3D print any style of case to put this alarm in.
Visible / inferred blocks
  • USB/input connector, labeled SH1 in extraction, with pins VCC, D-, D+, ID, GND, shield.
  • Li-ion charging circuit around U1 = MCP73831 with pins VDD, VBAT, PROG, VSS, STAT.
  • Dual 555-style timer blocks U2 and U3 with standard 8-pin 555 pin names.
  • Transistor circuits Q1 and Q2; exact transistor type/MPN unreadable.
  • LEDs/diodes, switches, resistors, and capacitors around timing and status blocks.
Visible / extracted values
  • R1–R12: extracted as 2 kΩ each, but image confidence is limited.
  • C1–C6: extracted as 10 µF each, but image confidence is limited.
  • U1: MCP73831.
  • U2/U3: 555 timer function; exact vendor/variant/package unclear.
Visible net labels
  • VCC
  • GND
  • RAW
  • BATTERYCUTOFF
  • TRIP
  • OUTPUT
Uncertainties to verify
  • Exact U2/U3 part number and package.
  • Exact Q1/Q2 transistor polarity/type and pinout.
  • D1/D2 diode type and orientation.
  • LED designators/colors/orientations.
  • S1/S2 switch type and normally-open/normally-closed behavior.
  • Whether all resistors are truly 2 kΩ and all capacitors are truly 10 µF.
  • Several point-to-point connections are inferred from visible net labels rather than fully traceable wires.
