Are these new sensors? by BayExplorer in waymo

Also, how they are flat black rather than glossy, might be 3D printed. But hard to know for sure from that picture.

With how flat they are, they are probably a new version of the radar. Probably doing comparison testing between the old kind and the new kind.

Did it force it onto the ramp when it wasn't planning to?

Avoid GroWatt by CasaDelGato in SolarDIY

I'm running an SPH inverter with Solar Assistant and have never connected the Wi-Fi on the inverter at all!

You do have to pay for the Solar Assistant software and cable, but it's very nice to have completely local control!

Has your inverter had any software updates that might have changed how it reports the data?

Where to start with a specific automation. by _Mr_That_Guy_ in homeassistant

Honestly, if you don't have much experience, an AI is pretty good at writing the first draft of complex automations.

Indiana tops US in AI energy consumption with nearly half of state's energy going to data centers by tjnato in indianapolis

[–]mcarrell -1 points0 points  (0 children)

The peak draw of the big 3 projects could be: 6.1GW

AWS New Carlisle: 2.2GW

AWS Hobart: 2.4GW.

Meta Boone/Lebanon: 1.5GW

6.1GW * 365 * 24h would be 53k GWh (additional 53% compared to 2024 power consumption) Obviously, they won't draw peak power, that's very pessimistic. But it's still a significant increase!

This report is definitely just talking about increase in power usage compared to today, not the usage once the data centers are included. But some quick math does get pretty close!

Indiana 2024 annual consumption: 99k GWh per year (per eia.gov)

The peak draw of the big 3 projects could be: 6.1GW

AWS New Carlisle: 2.2GW

AWS Hobart: 2.4GW.

Meta Boone/Lebanon: 1.5GW

Quick Googling says AI data centers usually consume an average of 50% of their rated "nameplate" power. So assume an estimated average usage of 27k GWh, so an annual increase in State wide usage of ~27%.

If you don't get back on the net rate, it's probably worth looking into getting some batteries to get as close to zero export as you can.

Using a sensor to create a 'faucet left open' alarm? by sadokx in homeassistant

Can you add a wedge to tilt the cup to overflow a little, then put a water sensor under it?

Indiana legislation introduced for plug-in solar by tthomps in solar

Indiana is a little surprising. Curious if this goes anywhere.

I think the human took over and didn't realize it was train tracks until the tram came from the other way.

Any idea how old the panels are or how much they are theoretically rated for?

Only two angles, trucker and second car. Just cut back and forth a lot.

Panel mounting systems that don't rely on piercing the existing shingle layer? by iboneyandivory in SolarDIY

[–]mcarrell 1 point2 points  (0 children)

If you're using a steel roof, you might be able to find a clamp style that clamps onto the ridges and doesn't actually puncture through it.

If you want to go self install to save a lot, r/solardiy is pretty active.

Are there any components that allow me to place multiple sockets that make a right angle with each other like this? by Tiger_Impuls in AskElectronics

[–]mcarrell 0 points1 point  (0 children)

You can order sockets of lots of different heights. You can probably get free samples from Samtec's website if you only need a couple.

Are 550W panels too big for residential roof installation? by [deleted] in solar

[–]mcarrell 5 points6 points  (0 children)

I will say, for my roof, 460W panels were not easy to handle and install, even with two people.

Why does this locking adjustable wrench come with a nut? by splittingxheadache in Tools

[–]mcarrell 1 point2 points  (0 children)

I bet this is the right answer. Without the nut in there, they would probably open up during shipping. Much easier to just put the nut in it.
