Yes, I had the wrong factor when changing from mm to µm.
Doesn't really change the conclusion though.

Gentlemen/Ladies we are talking about a piece of material 1" in length aka the spacer, I am no expert but will it make any different what it's made of and how much it expands? honest question really

[crasbe]

Simple guideline to spacers:
- Buy/make/steal a spacer in your desired length made from brass or copper.
- Use a galvanized, metric grade 8.8 bolt (not the cheaper, lower grade 4.8) and Loctite medium strength (or your preferred other brand).
- Torque the bolt till you feel confident it will neither snap nor be excessively loose.
- Done and be happy.

(Being happy includes not worrying about expansion. It's not that relevant.)

Me: gonna get a lot done in the garage this weekend

The Weather Forecast:

and then it was time to mount the second gen Toyota Prius electronic power assist steering brain module thingie






well the first thing I learned is that the lid comes off

what kinda alian space ship mounting bracket is that ?

[Gregski]

then it was off to the Organic Outdoors Finesse Station, OOFS

[Gregski]

I must admit I was very surprised how nicely this Toyota part bolted up to the Chevy truck, only one extra hole had to be drilled in the truck frame


Note: this module originally lived inside the cab of the Prius so it is not weather proof or tightly sealed at all !

[Gregski]

So the goal for this month, July 2023 A.D. (Another Deadline) is to have it run and drive !

we've been working kinda hard at lowering the bar so far to meet this important self imposed arbitrary deadline

could this be the final to do list?

• 1. mount the BMW E46 throttle pedal

• 2. Integrate Damien's BMW Safety Box control Arduino code into the VCU (the old pre Zombie version)

• 3. Wiretize all the low voltage wiring (VCU, Inverter, Throttle, Safety Neutral Switch, Resolvers, Water Pump, Oil Pump, Steering Module, CAN Bus, etc.)

• 4. Decide how to connect the second gen Chevy Volt battery charger high voltage orange wiring

• 5. Install some digital gauges (I am having our good forum friend Artur Kustusch - Jaguar XJR EV Conversion fandangle for me)

[Gregski]

so I snuck out and mounted the Lexus transmission oil pump controller to the '69 Chevy frame this morning (for what I hope is the last and final time) before it got to 80°F at 8:00 am

yup, yet another OEM bracket that looks like it just fell off of the USS Enterprise, but what do I know I'm not a Star Wars fan

dang it I just realized I fed those frame bolts in the wrong way, that will never pass tech, don't let Johannes see that!

[Gregski]

can you guess which grommet I needed ?

here's a hint

[Gregski]

you can't make this sh!et up folks

[Gregski]

five stores later...

I got two Brass spacers to Damien's design from one of those people on eBay that advertises spacers to your design for the equivalent of about $30 delivered.

Hello, do you mind sharing the ebay user and link?

I've no idea if they will ship to Bahrain but Damien does offer the spacers direct via his webshop.

I did recall seeing them on Damien's EVBMW Webshop a while ago, but I no longer see them, unless I don't know where to look, also I think the Services offering is new?

thank you, I swear I looked there before posting

[lsh3rd]

Have you looked here to see if anything in stock with McMaster-Carr would work? This has the potential of being a very inexpensive solution and avoiding overseas shipping/lead times: https://www.mcmaster.com/products/space ... ss+spacers

I think for the conductive surface, a quick dressing with the file would expose the brass.

[Gregski]

tell me you luv wiring without telling me you love wiring

[Gregski]

I don't know how you all do your wiring, but I don't do anything without my trusty hack saw

on a bit more serious note, repurposing the stock TOYOTA / Lexus OEM relay sockets is a bit of a PIA as there are 4 pin relays, 5 pin relays and umpteenth pin relays, plus some relays served multiple purposes, think rear window wiper and radiator fan type of deal

so as much as I wanted to have them consolidated and nicely mounted together, I only want to use 4 pin relays that are all the same style (not rating) for the oil pump, water pump, steering motor, and eventually iBooster

Why not use aftermarket sockets? Well I ordered some ( R95-160A ) but I am pretty sure they won't come with these really nice heavy duty 8 AWG wires like the stock ones do and the super wide 10mm blades

so here I just lopped off the non compliant 5 pin relay or whatever pin it was

[Gregski]

the same fate will come to this one, see how on the right those are actually two separate baby relay sockets and one is a 4 pin baby socket and the other a 5 pin baby socket, designed by the devil herself

[Gregski]

if you are in the mood for knowing a bit more about the batteries that will power this beast, I just uploaded this new video and it is pretty down to earth

think of each battery like a 9 gallon fuel tank, and I have two of them, the MPG for EVs is guestimated using 3.5 mpg so about 30 mile range per pack, and my original plan was to run three packs for a range close to 100 miles

however I have recently heard it's more like 4.5 mpg so closer to 40 miles per pack, we can only build, test, and see for ourselves
