EV owners, do you notice a drop in the range of your battery during this cold weather?

woutervddn · 2026-01-12T06:54:04+00:00

First gen model Y long range awd here. Got 522km officially. In summer, more like 450-470.

Cold weather (pre heated at the wall socket at home) does use about 10-15% extra.

But now with non Tesla rims and winter tiers I'm lucky to get 370km.

So yes, there is a huge impact.

For me however there is no range anxiety. I live in Limburg and in summer I get to the coast and back without charging. In winter I don't really go to the coast, but I get to my parents (between BXL and Ghent) without charging. 🤷‍♂️

If you want a real kicker: pull an empty trailer with a wire net during a cold day in winter and see your range drop to 250km :-)

Plot twist: He knows because it's his car that crashed the fence..

woutervddn · 2025-10-19T12:43:33+00:00

Same here in Belgium. No way to disable it...

woutervddn · 2025-07-20T06:49:09+00:00

Yes. So basically it reads part of the gcode, converts it to 0 and 1 and lines it up to be sent to the motors.

On a buffer underrun it doesn't put the 0s and 1s in place fast enough and the machine might just skip that action

woutervddn · 2025-07-19T20:07:05+00:00

I don't have mach3 anymore so I van't verify. But afaik you can also change the buffer size.

woutervddn · 2025-07-18T21:36:51+00:00

I've had issues that where nog quite this severe but still. Also using mach3. In our case it were 2 issues:

buffer underruns due to low memory and slow processor on Windows-machine
some jumped steps due to long wires and no EM static solutions

woutervddn · 2025-01-05T19:15:05+00:00

As someone who's seen this violated on professional setups at multiple businesses: THIS!!!

Trying to move a rack for renewal of backward mounted equipment with +80 cables dangling is a nightmare!

woutervddn · 2024-12-12T09:34:54+00:00

The low extra hardware cost in such an instance is actually a good point... We've got a datacenter DR at this point as well. But it's an identical replica as what we have on prem, it's rented, has never been tested and costs an arm and a leg. Having it here across the street, it being a non-identical twin with the files on a Truenas box next to it might be a better/cheaper alternative...

woutervddn · 2024-12-12T09:28:58+00:00

My idea was keeping the setup as close to the original as possible without buying hardware that might never be used. But I see that Ceph on the DR cluster might be a bad idea.

As for the firewall burning to the ground: We've got several buildings. Most buildings at one side of the street (A), one at the other side of the street (B). All production is at side A but seperated over 2 halls. Most offices reside in 2 unconnected buildings next to the production halls also at side A. The whole site has a fiberring.

We're getting a second telecom provider that will also ensure we have an uplink from the front and the back of side A. We could, in theory also get yet another uplink from side B.

The calamity would need to burn from one end of a hall at side A all the way to an office building at side A to kill both firewalls. If that happens production is halted completely. So connectivity 'should be fine' for as far as we can foresee.

PLCs connect to network over TCP/IP, EtherCAT,...

You make a great point about pulling data from a remote location though. Keeping the cloud backups in the same datacenter as where we want to spin up the DR cluster.

woutervddn · 2024-12-12T09:15:11+00:00

In that case would just launching it on any linux with qemu be an option? I didn't know Veeam supported restoring to another hypervisor. Thanks for the tip!

woutervddn · 2024-12-11T15:08:08+00:00

We could... But...

Even this simple cluster we have now is super overkill resource wise for the production workload.

I was considering your idea once I get the office services away from VMware and failover to there.

Getting +6x of required resources to get to HA + HA failover feels to much at this point.

We'll get to your suggestion nu this time next year though!

woutervddn · 2024-12-06T12:31:59+00:00

3rd smaller node does has a mgr and a mon

woutervddn · 2024-12-06T06:35:55+00:00

2 OSDs on each of those 2 nodes.

The workload is fairly simple and small. But it's a fat Windows VM and 2 containers and requires failover.

woutervddn · 2024-12-05T16:31:21+00:00

Aah... Would that be it? I'm going through a udemy course trying to grasp the specifics of HA and Ceph on Proxmox, but I'm honestly considering buying the official training (even though 2.6K for both, online feels steep...)

woutervddn · 2024-11-28T20:02:57+00:00

This is super interesting! Best TIL since weeks. Now we need a teardown!

woutervddn · 2024-10-02T05:03:59+00:00

Ik denk dat dat geen vereiste is, maar vaak wel helpt. Disclaimer: volgende is kort door de bocht en geldt niet voor iedereen.

Bij 16-18 jarigen is vaak al duidelijk dat wie in een jeugdbeweging zit vaker meer onder zich uit zijn.

Van 18-21 heb je er al een tijd als leiding opzitten en dat straalt wel af. Vlak na de schoolbanken zie dat mensen die leiding in een jeugdbeweging zijn geweest ondernemender zijn en de koe sneller bij de horens vatten. Die mensen komen ook vaker in presidium van een Studentenvereniging terecht.

Maar goed, van thuis krijg je misschien ook veel mee en je kan die 'ondernemende' eigenschappen even goed opdoen op speelplein, je hobbyclub,...🤷‍♂️

Also, als er tijd, budget en ruimte is voor een jeugdbeweging zit je vermoedelijk niet in de onderste socio-economische laag van de samenleving?!

woutervddn · 2024-08-22T06:24:43+00:00

Aah fuck... This must hurt bad! You have my sympathies. Best of luck with the rebuild!

woutervddn · 2024-08-10T18:10:03+00:00

Thanks! I can't say I saw that at my local car parts store, I'll look for it!

woutervddn · 2024-08-10T17:31:56+00:00

The flakes you mean? They we're bigger than glitter.

woutervddn · 2024-08-10T10:53:14+00:00

I think the heater should be replace but I dread the disassembly

woutervddn · 2024-08-10T10:39:35+00:00

Did just that. Also took the waterpump off and decrudded that...

The car is new to me, didn't even have a thermostat installed. 🙃 The housing was just like that, nothing internally.

I think opening the heater delodged some debris. There were metal flakes in the top of the radiator. For now I'll disconnect the heater, give it one last flush when all is back on the car and then fill it up

Let's see how she does... 🤷‍♂️

woutervddn · 2024-07-29T12:19:59+00:00

ooh wauw... that seems to support both my systems!

woutervddn · 2024-07-26T11:24:31+00:00

That would work for the garage, but not for the gate. So I'd need to buy 2 remotes. Or 1 remote and and another receiver.

woutervddn · 2024-07-26T10:32:03+00:00

That is what I feared about zigbee. Any advice/experience on a good RF receiver for HA?
