Change History from V1: -13.56MHz tuning -larger instruction font -put some stuff on the back #template I wanted to create a business card that has some functionality and shows off a bit of my portfolio IRL: -NFC to my flux page -here's the [instructables](https://www.instructables.com/PCB-Business-Card-With-NFC-Make-Yours-With-NFC-QR-/) -Put a bunch of modules on it Find the BoM [here](https://www.digikey.com/short/2db2vnmp)

I want to create a standard interface from my PCBs to my test equipment. My equipment: PSU: Rigol DP832 Scope: Siglent SDS 1202X-E WaveGen: Siglent SDG810 Logic Analyzer: DSLogic Plus 400MHz VNA: NanoVNA V2 6 scope channels (4 1X, 2 10X) 8 Logic Analyzer channels 1 Wavegen channel 4 Power Nets ( 2 pins each) (tie power nets to oscilloscope inputs) #template #testing

PCB design for Beavis Audio Research's Noisy Cricket Amp. Designed to be an onboard amp for an instrument with a speaker in the body. JFET buffer replaced with op-amp buffer from Jack Orman because JFETs are currently hard to find. LED is dimmer than the original because my eyes are sensitive. ☀️ http://beavisaudio.com/projects/noisycricket/ https://electrosmash.com/noisy-cricket-analysis

Me agradezco a mí, quien pese a las dificultades impuestas por la propia plataforma, supe atacar y defender, obteniendo así el resultado que yo esperaba. No recomiendo Flux.

R1 changes: -Changed LED part to Red LEDs -adjusted resistor value of buck converter -Changed source for USB-C Connector -Removed exposed soldermask on buck converter with negative soldermask expansion -Order with black soldermask Modified by markwu2001: - Adjustable Brightness, - 85-90% Drive Efficiency - <5W Operation (Can use 5V 1A Plug) This project can be purchased from LCSC Original Description: Daddy's second circuit board. A sign to let my wife know when I'm on a call. Activates with a slide switch and is powered by USB-C.

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, a 3PDT true bypass wiring setup, and an example potentiometer that can be copy/pasted throughout the circuit. size is a good default size for a 125B enclosure. 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. Meant to be used with the 3PDT Breakout Board on my profile. #template
