- Comment on Biden Administration Is Said to Slow Early Stage of Shift to Electric Cars 2 months ago:
The electric grid will be ready when it needs to be ready. Power companies aren’t going to just leave EVs on the table, even if they have to beg for money to upgrade.
There’s a post around here somewhere about a Chinese (BYD) EV for $15,000. I didn’t look at it, but that’s going to be entry level with few bells/whistles. Still, that’s cheaper than any US ICE vehicle I know of.

- Comment on Advice on first 3D printer 2 months ago:
I’ve had a couple: a cheap Anet A8 clone, and a Prusa MK3. I did ABS and PLA on the A8, and PLA and PETG on the Prusa. My Prusa is now outdated, and I don’t have the A8 anymore. Both printers look the same to a layman. Here’s what I know.
The A8 was dirt cheap. Like $250 cheap. I think the Prusa was about $600 a couple years later. The print size was the same or very close on both, (250x250, 210 high).
The A8 relies on manual bed leveling. It sucked. The Prusa has a magnetic sensor that creates a level map in firmware and adjusts the printhead to follow the warp of the bed automatically for every print.
The A8 has an aluminum bed. It required kapton tape, or gluestick, or some way to get the print to adhere to the bed. I eventually used a sheet of glass with gluestick. The Prusa has a PEI bed, that just works as long as it’s clean.
Both of them have an E3D hotend with interchangeable nozzles using an M6 thread. Not the easiest thing to swap, but pretty simple anyway. The built-in Z-correction on the Prusa only selects for a few standard nozzle sizes (.25, .4(standard), .6, .8, and maybe 1.0). That’s a good range and probably enough. You can also forgo the built-in Z-adjustment and use any number of first-layer calibration models on the internet.
Both of them have a heated bed. And of course heated nozzle. You’ll have to check the temperature ranges yourself and see if your materials match.
You’ll have to select a Slicer program to use with your printer. I used Cura with the A8, and Prusaslicer with the Prusa. It’s up to you if you want to tinker more (Cura) or just print (Prusaslicer). There are so many options here, it’s impossible to touch on them all. This is where you adjust the layer height, and as long as your Z-axis motors can handle the fine adjustments it should be fine.
Neither come with an enclosure, which is something to consider for certain materials. I built one for my Prusa out of an IKEA table, to keep furry family members out of it.
In all, I wouldn’t recommend the A8 as a beginner printer. I had a lot of frustrations with it. Bed adhesion, bed leveling, belt tension. Very few successful prints, but I learned what I wanted for my next printer. The Prusa “just works”, and I’ve had it for 5+ years now. There was also a concern with the A8 setting things on fire. The Prusa firmware can detect temperature runaway and abort automatically.
As a hobbyist, consider how much time you want to spend upgrading the printer. Both of these have a lot of “home-brew” parts on the internet allowing you to add various features (belt tension adjustment, better part cooling, etc.) My MK3 is now an MK3S+, and still going strong. I’m considering if I want to upgrade this to the MK4.

- Comment on Followup on the vehicle "kill switch" mandated by the Infrastructure Bill 4 months ago:
There are about…50?..Federal Motor Vehicle Safety Standards (FMVSS). The way the law is written, personal owners are allowed to disable any safety features mandated by these standards. But it’s illegal for one of those listed entities (manufacturers, dealers, rental places, and repair businesses) to do it. So, while you personally are allowed disable those items, you can’t bring your car to a repair business and have them do it for you.
But, there are also State Regulations to consider. The Federal government doesn’t force anybody to wear a seatbelt, they just require the car to have them when you buy it. The individual states regulate seatbelt use. While the Federal Regulations say you’re legally allowed to remove the seatbelts, most of (if not all) the State Regulations say you have to wear a seatbelt while driving.
That being said, there’s a mechanism for those listed entities to get an exemption, allowing them to disable safety features. Consider someone in a wheelchair. They have to get a car modified if they want to drive, and they’ll be unable to do it themselves. So they bring the car to someone that can handle the modifications (say they need to disable the airbag), and that business will send a request to NHTSA, and NHTSA will give them an exemption for one modified car to remove or disable the airbag.
- Comment on Followup on the vehicle "kill switch" mandated by the Infrastructure Bill 4 months ago:
Exactly. There’s too much possibility of false positives in most of these technologies to be safe. There’s a section where NHTSA covers how they should handle disabling a vehicle in a dangerous situation. For example, if I’m in the middle of the woods camping and drinking, should I be able to drive my car to escape a forest fire?

- Comment on Followup on the vehicle "kill switch" mandated by the Infrastructure Bill 4 months ago:
Personal owners are allowed to do whatever the hell they want to their vehicles regarding Federal safety standards. Weld the doors shut, go ahead. Remove all the airbags, not a problem.
