Starting out:

The first thing we did was file for 15% discount for goBILDA.

Next we made a shopping list with check boxes based on the Parts List.

What I wished I did next was reference the Errata Tracker to see which parts were incorrect.

We are ordering parts from 7 stores:

• DollarHobbyz
• goBILDA
• DigiKey
• Amazon
• Mouser
• BasicMicro
• JLCPCB

DigiKey was a breeze to place orders. You can upload the .csv to bulk ordering and it will also recommend replacement parts if sold out. Took about 15 minutes to order.

goBUILDA was the most difficult. Yes it has bulk ordering, but it still requires  manual entry. Took about 3+ hours to add items and verify the correct amount of items.

For us the following items were out of stock:

• Power Measurement Unit INA260
• 1102 Series Flat Beam (3 Hole, 24mm Length) - 2 Pack
• 1106 Series Square Beam (29 Hole, 232mm Length)
• 1106 Series Square Beam (12 Hole, 96mm Length)
• M4x8 Socket Screw 25-pack
  

We still need to find replacements for them or sign up for notifications for when they get restocked.

Side note: Found a really nice DuPont/JST/Molex crimping kit that should cross a good chunk off the shopping list. It can crimp Molex, but doesn't come with Molex crimps.

Ordering Process Possible Improvements:

• Wish GitHub parts list had check boxes.
• Too many shopping carts.
• Instructions should mention bulk ordering.
  • Digikey has an order by list. You can upload the csv.
• Have to be extremely cautious about double ordering an item. Double/triple checking prices.
• Good to make note of running total for each section to help prevent ordering oversights.
• Need to automate the buying process. https://www.gobilda.com/bulk-order/ 
  • Possibly with codemonkey
• Was not aware of Errata Tracker for PCB board. Needs to be noted.
• Raspberry Pi ribbon cable not explicitly specified to be female to female.
• Part PCA9685 is listed twice in the parts list
• Most up to date info on Slack, but there is a 90 day limit.
• In parts list “laser cut parts folder” link is not found.
• There seems to be some oversimplification when comparing parts list wiring section and the wiring ReadMe. Almost led me to purchase wrong parts.
• Wiring ReadMe doesn’t list Molex connectors in the “In total:” section.
• Wiring ReadMe keeps mentioning “Molex connectors”, but I think it means Molex crimps. The PCI-E connector is the one housing the Molex crimps.

Planning DIY body plate:

We are planning on cutting the Body Plates ourselves. I downloaded the .dxf files, loaded and dimensioned them onto AutoDesk AutoCAD to get an idea how much 1/8 inch thick acrylic we need to buy. Our laser cutter workspace is 32x18 inches and it looks like we need 4 sheets that are bigger than 10x13 inches.
