Wow, I wonder why SpaceX which has a monopoly on reusable rockets are charging as much as they can from their customers.

Lol, lmao even

Ah sorry, I guess it's called FCAW and not MIG. I am not using any gas to protect the weld. From what I've seen on the internet it will spatter no matter what, but I will check the polarity of the cables

Okay, yesterday I tried out MIG and here are the comparisons with stick welding:

  1. Mig doesn't leave much of slag at all, the residue you get is more in a "dust" form which is much easier to brush off compared to the slag stick welding leaves
  2. Much harder to get impurities into the weld itself
  3. Harder to follow the weld line compared to stick welding using pencil holding technique
  4. Have to play with the settings quite a bit before you get consistent line
  5. Much better for spot welding because you can position your hand and electrode, and press the trigger when you are ready, avoiding additional hand movement.
  6. Surprisingly the spatter is more aggressive and gets stuck to surface more than my electrodes. Could be due to the wire I am using

These are my notes so far.

 

Been doing stick welding for a bit, but when it comes to thin steel such as on cars, sticks blow right through. I was thinking about getting a flux core machine to do some exhaust work on my car because I don't want to mess with gas.

What should I know about flux core? What are the biggest cons about it?

What a load of crap you are spewing.

Porche 911 GT2 (993) produced 331kw (443hp) with an air cooled engine.

It would be a real bummer if this came out to be untrue. However it's simple enough to replicate, so we will know soon enough

Insane capacity batteries

Lossless power transmission via wires

Better magnetically levitating trains

Much more power efficient computers, electronics

The list is huge

127c is the maximum operating temperature. If it goes above that, it looses superconductivity.

This material below 127c (which is insanely hot for superconductors) will be superconductive.

Operating range is -273c to 127c

Are there any european cars that can be considered "muscle" ?

 

ICE aren't growing much in size and are getting more and more efficient. Why not make them air cooled? Porches used to be aircooled, and those were performance cars with the engine in the back. I would imagine having an engine in the front might be easier to cool, no?

 

Changed the light bulbs into white LED's (they didn't have blue ones) and from orange they turned yellowish.

I think this might pass the inspection, thank you for suggestions ^^

 

So on the integra the front turn signal is made oit of two bulbs, I need the one circled in red to be white to pass inspection in my country. The problem is the bulb itself is white, but there is an orange filter inside and I cannot remove it.

My idea was to put in a bright blue bulb in there to compensate for the orange filter and make it appear white. Is that doable? Has anyone tried?

Do babies have memory? (self.asklemmy)
submitted 1 year ago* (last edited 1 year ago) by DominicHillsun to c/asklemmy
 

Unsure if babies can form memories ages 1-2, my oldest memory is from around age 3. They do learn words when they are around 1 year old, so there must be some capacity for memory? What is going on there?

 

My battery died (can't get above 10.5V, loosing voltage while sitting etc) and I need to get a new one. What should I look out for? There are a lot of different types of them like AGM, Lithium Iron, Flooded Acid etc

Car is Integra (1998)
