Parts Spreadsheet
Below is a spreadsheet containing all parts required to make a min-eVOLVER.
Read the notes below the spreadsheet as well.
Don't miss the "Consumables / General" tab. These items also need to be acquired before running experiments.

min-eVOLVER PCB
If you are making a min-eVOLVER Control Board PCB from scratch you have two options (as of 11/20/2024):
[Recommended] Order an assembled PCB from PCBWay (guide below) or another manufacturer
Buy the parts needed from Digikey, order the PCB from PCBWay or another manufacturer, and solder the board yourself
NOT recommended for anyone not already familiar with surface mount soldering.
An interactive bill of materials (for part placement) can be found here. Download it and open it into your browser.
Ordering an Assembled min-eVOLVER PCB from PCBway
Make an account on PCBWay.
On the homepage, scroll down and click on PCB assembly

Choose the following:
Turnkey, Single pieces, Both sides, fill out the quantity you want, select No "Select PCBway's PCB Order #", uncheck PCB Specifications, and click the green 'Calculate' button.

Download the following files from this folder, upload to PCBway, and click "Submit the File Now":
Gerber files: min-eV-gerbers_240731.zip
Parts List (BOM): BOM_PCBWay.xlsx
Centroid File: PCBWAY-min-eV-positions-centroid.csv

Wait for PCBway to review your order (1-2 business days) before paying
Pump PCB
Should be ordered from PCBWay or another manufacturer. You can find the .zip of the gerber files here. Assembly is not needed.
min-eVOLVER Case
Options:
We use Protocase to manufacture the cases
Request a quote for the number of cases you require by emailing Jenn Hurd (jhurd@protocase.com)
Mention you want to order the previously ordered name and number below:
Boston University min-eV Case Rev2.1 T120324039-205634-1
For other manufacturers, give them the .x_t, .easm, and .step files found here
Request sheet metal construction out of 18 gauge steel, ideally a powder coated exterior
12V Power Supply
Several 12V power supplies were tested and were selected for reliability and low noise. While most 12V power supplies should work well in the short term, long term usage may vary. Use a different power supply at your own risk.
Vial Cover
NOT AN OPTIONAL COMPONENT - Protects OD photodiodes from environmental light, which will completely change your OD calibrations. Also protects smart sleeves from spills and splashes.
3D print the latest vial cover to allow for more consistent OD readings. Choose the cheapest black FDM printing on hubs.com, shapeways.com, or a local 3D printing shop and give them the .stl file in the github repository.
eVOLVER Smart Sleeves
May be purchased from Fynch Bio. If interested in making your own see the main parts sheet and follow this assembly guide. This is not recommended for its added complication (you will need to machine the aluminum tube for example), but will save money.
Consumables / General
Listed in the "Consumables / General" sheet of the above spreadsheet
Anything not listed as (Optional) is required for a full experiment.
You need a thermometer for calibrating temperature - we suggest this one.
If you plan to run multiple min-eVOLVERs from a computer, you will need to have a USB port available for each one. You can use a USB splitter dongle to accomplish this. Example here.
