Arduino Uno shield for the BrewPi Legacy Remix project.

This is an new board design which incorporates an I2C LCD header in addition to the original parallel LCD header on the RevC. The I2C display is supported in version 0.5.3 of BrewPi Legacy Remix Scripts, WWW and Tools, coupled with version 0.2.12 of the Arduino Firmware.

Supported Features:

• Wireless to Serial Bridge (Bluetooth or ESP8266 module)
• Door switch
• Alarm
• Heat/Cool Relay
• Rotary Encoder w/Pushbutton
• Heat/Cool LEDs
• OneWire Selector A0/A4 (required for I2C)
• Three OneWire connections
• I2C LCD; or;
• Parallel LCD
• RJ45 connector includes support for:
  • OneWire
  • Door Switch
  • Heat/Cool Relay
• All Arduino headers available

BOM:

• From Mouser (by using this link you can view all of these parts on Mouser and simply click the “Order Project” button):
  • 7 ea 0.1μF Ceramic Capacitor (C1-7)
  • 1 ea 1.0μF Ceramic Capacitor (C8)
  • 1 ea 10kΩ Trimmer Resistor (R1)
  • 4 ea 10kΩ Axial Resistor 1/4W (R3-5, 12)
  • 1 ea 150Ω Axial Resistor 1/4W (R11)
  • 1 ea 1kΩ Axial Resistor 1/4W (R8)
  • 1 ea 20kΩ Axial Resistor 1/4W (R2)
  • 2 ea 220Ω Axial Resistor 1/4W (R9, 10)
  • 1 ea 2kΩ Axial Resistor 1/4W (R7)
  • 1 ea 4.7kΩ Axial Resistor 1/4W (R6)
  • 1 ea 2N3906 PNP Transistor
  • 1 ea SN74HC595N 8-Bit Shift Register
  • 1 ea 16-pin IC Socket
• From Adafruit:
  • Shield stacking headers for Arduino
  • Break-away 0.1" 36-pin strip male header - Black - 10 pack, more than enough for:
    • 2 ea 2-pin Header 2.54mm pitch (or 1 ea 4 pin)
    • 7 ea 3-pin Header 2.54mm pitch
    • 4 ea 4-pin Header 2.54mm pitch
    • 2 ea 6-pin Header 2.54mm pitch
• 2 ea Jumper Cap (or you can use a female/female Dupont jumpers but caps are definitely better looking)
• 1 ea RJ45 Socket

Other items you may want in order to complete your project:

• LCD Display, either;
  • 20x4 LCD Parallel, or;
  • 20x4 LCD I2C
• 5v 2-Channel Relay Module
• Rotary Encoder - You want a magnetic encoder, no pull-ups, and 20 detents
• Knob for Rotary Encoder
• Rotary Encoder Breakout Board
• At least two DS18B20 Waterproof Temperature Sensors
• Assorted Dupont Jumper Wires (male-male, male-female, female-female)

Sunrise alarm high current LED driver shield with power input for LED Raspberry Pi 0 shield (not hat - EEPROM not included)

Made for Drashna (drashna#9334) on Discord. -RGB LED is a 6025. OSH Park doesnt officially support internal cutouts, so I’ve cut slots along each side. You’ll need a small pair of shears and a file to cut it out. Hopefully the pads line up, I couldn’t find any decent datasheets for the 6025 LED. -Diode is a 2010 (5025 Metric) 1.52x2.65mm hand-solder SMD. Direction is from SWIN to SWO (SWitch IN to SWitch Out). -VDD is common anode/cathode for the LED (I can never remember which, and it doesnt matter so long as you get it right). -B, R, and G are the LED pins for Blue, Red, and Green. -SWIN and SWO are duplicated on either side of the PCB to make soldering them in chains a little bit cleaner. just connect them side-to-side and top-to-bottom with small wires and they’ll chain together. Any questions, feel free to DM me on Discord @ Construc_#6969

Battery charger using buck power converter

A simple board for adding the proper components to a cable. I am using this on a genesis model 2 at the moment but it can be adapted to anything that needs components cable side.

For Sega

C1,C2,C3,C4 - 220uf 6.3v smd

R2,R3,R4 - 75ohm 0603

R1 -470ohm

Headphone Jack - PJ-320- 3 pin I haven’t tested these jacks out yet but they look fine I guess.

Case- https://www.ebay.com/itm/5pcs-Waterproof-Plastic-Electric-Project-Junction-Box-55x35x15mm-DT/252497974090?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

I have spaced the holes for the possible use of jst connectors on the wires.

This exact design as not been completely tested so use at your own risk.
