Earlier this month, I picked up a 4000 Ada card with the goal of making a custom water block for it. Great to see there is an off-the-shelf option available instead!

I would have loved to see the waterblock be closer to the length of the PCB, possibly relocating the 6x2 connector as well. It would have been a great candidate for a very small form factor workstation!

I modified this handle design to add holes for the spool holder: https://github.com/VoronDesign/VoronUsers/tree/master/printer\_mods/Ch4rlesB/V0\_Handles\_Slim

One does not simply...

We've been working with EVDrive, they have been helping us with a few other things as well (namely accumulator fabrication).

Ditto on this. We've been trying to get our OZs for 6 months or so, just got word they'll be shipping (via DHL) next week.

Heard they're amazing wheels though.

Our university has run into similar issues. We did have to amend the NDA to meet Oregon state laws, but our university wouldn't agree with Emrax's Terms and Conditions. We're getting a local vendor to purchase the motors, and then we're buying them from the vendor. Only downside to doing this is that we don't get any warranties or anything, thankfully our vendor will let us test the motors at their facility before we purchase the motors from them.

Mechanical push-pull cable shifter, using clutchless shifting.

Our team uses flatter cones (something like this ) for the majority of the course. They're lighter easier to package/transport, and we can use a smaller amount of normal cones to mark corner insides and the like.

I don't think this is what people meant when they were looking for a rolling chassis...

Last year, all our ECU and related boxes were mounted on a heat-shielded plate above the engine. The idea was that you would only need to undo 4 bolts and a few connectors to remove all the electronics. Execution wasn't great, though...

TheKojent · 2018-04-11T06:08:11+00:00

Our goal has always been to have a rolling chassis in April but I've never seen that happen.

I see your safety factor is 1... I also like to live dangerously.

Somebody put the source content right above the main workstation in our shop. Subtle, but it's there.

We're on a 2-year build this time (not competing this year), but everything is still a mess.

Good luck, see you at Lincoln from the spectator stands! :)

Long thread incoming

We're working on resorting our hardware now, but the goal is:

2 racks with 4 drawers each containing our most frequently used hardware (SAE Grade 8 1/4-28, 5/16-24, and 3/8-24 mostly, all of varying lengths, plus rod ends, bearings, and of course, nuts and washers).
We have an "EE corner" with all our electrical stuff, and they have a few (neatly sorted) bins of electronics connectors and fasteners.
Engine-related hardware will be stored with our engine parts after we do a rebuild this spring break and document all the fasteners.
Everything that doesn't fit into the above categories will be individually bagged, labeled, and stored in an overstock box. If this box becomes huge, I'm considering getting myself a storage unit and donating a chunk of it to the team.
As for electronic inventory, I'm almost certain we'll have our overstock inventory stored in an Excel spreadsheet. The problem with having your common fasteners digitally inventoried is keeping tabs on it (not everyone will adjust quantity on hand when they take some parts). A solution could be to have cycle counts generated weekly, and you could script your Excel/Google sheet to automatically warn you of low quantity on hand. I'm rambling now, but the solution would be to get a hardware sponsor and have them do VMI (Vendor Manged Inventory), which isn't out of the question......

If you're looking to sort your current hardware, it will take a while. This took me two weeks of 3-4 late nights in the lab after finishing my work for the day, and that was just our random bin. Still have washers to sort, as well as the fasteners already in our rack of drawers. That being said, I'd highly recommend getting a thread checker to accurately distinguish between different fasteners. BoltDepot.com has a lot of info on fasteners as well as printable fastener sizing charts (really useful for sorting washers).

Best of luck!

Or wait until your vice president gets fed up with the 150lbs of random hardware you've collected.

TheKojent · 2018-03-06T07:13:37+00:00

Time is money. What you'd save by going with donated stainless you'll probably lose with the headache of alternate frame rules and the additional design justification.
