WEL Inventory
The component stock portal: search what the lab holds, build a cart and submit a request as a project team.
What the lab holds, and how to ask for it
WEL Inventory is the lab's component stock system. The full listing is on this page — search it, build a request list and send it to the lab, without signing in.
The same stock is also served by the WEL Inventory portal, which adds team accounts, a tracked request queue and automatic stock updates on approval. Both read the same component spreadsheet.
inventory-app/. It needs a host that can
run Python — the lab server, or a free service such as PythonAnywhere. Once it is
running, put its address in SITE["inventory_app"] in
_src/build.py and every link on this site will point at it.
Setup steps are in inventory-app/DEPLOY.md.

Your request list 0
Your list is kept in this browser only. Sending it emails the lab, who check the stock and confirm. Nothing is reserved until they reply.
How to raise a component request
Two ways, depending on whether the portal is running.
1. Find the parts
Search the listing above by model number, description, type or where it is kept, and filter by availability.
2. Build your list
Set a quantity for each part and add it. The list stays in your browser, so you can come back to it later.
3. Send it
Add your team name, members and what it is for, then email the list to the lab or copy it as text.
4. Collect
Lab staff check the stock and confirm. Nothing is reserved until they reply.
What the admin side does
Review requests
Pending, approved and rejected requests, each showing the team name and every member with their roll number. Approving issues the parts and decrements stock; stock is checked before the request goes through.
Manage stock
Edit quantities in place, and see a low-stock list of everything at two units or fewer so reordering happens before a course needs the part.
Bulk import
Import the component list from an Excel workbook or a Google Sheet link. Columns map to type, model number, description, link, location and quantity.
Something missing from the stock?
If a part you need is not listed, or the quantity looks wrong, tell the lab staff rather than assuming it is unavailable — stock is updated as parts arrive.
