# Random Transistor Overdrive ## Description Guitar pedal starter template based on project by Mark Wu. Includes schematic and PCB layout for basic DIY pedal hardware. This includes two 1/4" jacks (one for input and one for output), a 9V power supply (including LED), a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit. The headers are meant to be unpopulated so that wires can be soldered to the pads. PCB design rules imported from the JLCPCB 2-layer stackup template. #template ## Project Details - **Owner:** puig - **Created:** 5/17/2024 - **Last Updated:** 5/17/2024 - **Visibility:** Public - **Copies:** 3 ## Key Components ### D1 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht~gr.md) - Series Resistance: 0.42Ω - Emission Coefficient: 3.73 - Breakdown Voltage: 0V - Saturation Current: 93.2e-12A - Forward Voltage: 1.70 **Pins:** - A [pin 2] - K [pin 1] ### D2 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht~gr.md) - Series Resistance: 0.42Ω - Breakdown Voltage: 0V - Saturation Current: 93.2e-12A - Emission Coefficient: 3.73 - Forward Voltage: 1.70 **Pins:** - A [pin 2] - K [pin 1] ### D3 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht~gr.md) - Saturation Current: 93.2e-12A - Breakdown Voltage: 0V - Emission Coefficient: 3.73 - Forward Voltage: 1.70 - Series Resistance: 0.42Ω **Pins:** - A [pin 2] - K [pin 1] ### D4 — [1N914](https://www.flux.ai/jecstronic/1n914~uun.md) - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Part Number: 1N914 - Manufacturer Name: NTE Electronics, Inc - Part Type: Diode - Datasheet URL: https://www.nteinc.com/specs/original/1N914_A_B.pdf **Pins:** - A [pin 2] - K [pin 1] ### J1 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/generic-pin-header-01x02-2p54mm-vertical~4uy.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### J2 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/generic-pin-header-01x02-2p54mm-vertical~4uy.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### J3 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/generic-pin-header-01x02-2p54mm-vertical~4uy.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### Q1 — [2N3904](https://www.flux.ai/adrian95/2n3904~a6d.md) - Datasheet URL: https://www.nteinc.com/specs/original/2N3904.pdf - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Part Number: 2N3904 - Part Type: Transistor - Manufacturer Name: NTE Electronics, Inc **Pins:** - B [pin 2] - C [pin 3] - E [pin 1] ### SW1 — [Connector 01x06](https://www.flux.ai/jharwinbarrozo/connector-01x06~yh.md) - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] - Pin_4 [pin 4] - Pin_5 [pin 5] - Pin_6 [pin 6] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/puig/random-transistor-overdrive~14](https://www.flux.ai/puig/random-transistor-overdrive~14).* --- *Generated from [https://www.flux.ai/puig/random-transistor-overdrive~14](https://www.flux.ai/puig/random-transistor-overdrive~14)*
