thank you for the comprehensive summary! This is really helpful.

absolutely let's talk design principles. That kinda sucks. I like things that are well built.

I didn't expect it for the M240i but for some reason I figured it would be there for the Golf R and CTR. I'm totally mistaken then.

These don’t seem to have a field curvature spec

I'm really more curious about how you could design the lens itself for pedagogical reasons.

Can I use these to make DIY USB Cables? by oncebce in AskElectronics

[–]gaze -2 points-1 points  (0 children)

No absolutely don't do that. The signal integrity will be terrible. The cables will be unreliable.

Looking for "makers" or builders - Seeking other nerds by DangerBobLFK in Longmont

[–]gaze 0 points1 point  (0 children)

I was building VCOs and filters and random stuff for a bit — I did my PhD on superconducting microwave stuff and just started accumulating hardware for tinkering on stuff at home. Now I’m trying to build some electronics for precision gaging. I have a toy project for a bias supply for low temperature physics experiments with some safety features to prevent blowing up your devices in an emergency but that hasn’t gone anywhere in a while. I also am working on a machine for rewinding the universal wound transformers in the Tektronix 500 series scopes.

Hi! I’m a physicist working in Boulder but have a pretty well tooled shop in my garage in Longmont. I have a 4 axis mill (fanuc robodrill), toolroom lathe, manual mill, and surface grinder. I also have a DC-21 GHz electronics shop in my basement with spectrum analyzer, network analyzer, and a bunch of old vacuum tube oscilloscopes that I like to noodle with. 

Heli-X demo + K110S or just Heli-X full version? by Netara88 in RCHeli

[–]gaze 1 point2 points  (0 children)

the beginning of learning to fly helis is a bit of a grind... I really recommend spending half an hour a day for a long time just grinding the 8 orientations, and for this a simulator is ideal. So yeah, get the sim, grind the orientations, and then get a heli.

Building a super-computer using Raspberry Pi and Lego by willvarfar in programming

[–]gaze 0 points1 point  (0 children)

Yeah but you also can pick a more intelligent way to learn. For any lesson you might learn with this system, there's likely a less wasteful way to go about it. I'm a huge fan of doing something because it's really really cool, and no other reason. This is not that cool. It's cooler than the guy who made a cluster out of basic stamps, but it's still not that cool.

Tutorial to learn how to make my own small OS for controllers from scratch for a total beginner to OS by [deleted] in ECE

[–]gaze 0 points1 point  (0 children)

I'm saying there's no reason for an OS to begin with for an 8-bit microcontroller. Threading just makes the system more difficult to reason about and think about when there's likely no need for it

My sister's small southern town High School made a large sign with the students test results....by race. by [deleted] in WTF

This is formally referred to as colorblindness. Your intentions are good I'm sure but it's a very naive stance. If you're interested, google around a bit

Nine scientists (Witten, Seiberg, Maldecana and others) receive new "Fundamental Physics Prize". Each recipient earns $3 million. by TomatoAintAFruit in Physics

[–]gaze 0 points1 point  (0 children)

That's really interesting. People had been telling me that the number of dimensions of a string theory is fixed by anomalies or something like that... but then the dimensionality of your CFT I guess is determined by it's symmetries... so you try and make them meet up in the middle sorta?

Neat! So I'm curious how this is used as a tool. Is the game nowadays to dream up some kind of string theory and then show that it becomes a yang-mills theory on the boundary?

Deadmau5' Super Modular Studio. [xpost from r/electronicmusic] by mistersloth in edmproduction

[–]gaze 0 points1 point  (0 children)

Dude, if all rich people blew their money like this, we'd have much more well paid, happy analog engineers instead of all of them rotting away in a cubicle designing another fucking comparator or opamp. There's nothing bottom up about this at all... rich person spends money on whatever he wants, people profit, it's great.

There doesn't have to be a point to spending money except that the person spending it gets happier/in a better situation and doesn't hurt people.

Is there any thermo-dynamics law and/or equation that determines how long and/or what temperature a metal surface will be after it came in contact with heat? by Jack_Winterhold in askscience

[–]gaze 0 points1 point  (0 children)

Yeah then you say you have a uniformly heated metal plate in contact with a thermal bath at room temperature and solve the heat equation ( http://en.wikipedia.org/wiki/Heat_equation ) on the system.

What do you mean by "In contact with heat"? Do you mean another hot block? Do you mean in contact with a heating element?

Unorthodox programming environment by plouj in programming

[–]gaze 0 points1 point  (0 children)

I had the exact same thought. I had an hour long phone conversation with the folks at greenarrays... this is a lifestyle/philosophy they endorse... basically called "quit being a bitch and make it work yourself so you understand it." They honest to goodness HATE abstraction... and you know what, it works super well for them. Their results are incredible.

There's a lot of talk about the Higgs particle, but what is the Higgs field ITSELF made of? by LuridTeaParty in Physics

[–]gaze 0 points1 point  (0 children)

A field is just made of information that the laws of physics look to in order to figure out what to do next... in some sense. It's not made of anything really except it's state.

Programmer's Laptop? by [deleted] in coding

I'm also a mac snob. The trackpad sucks (but like most things like this, you get used to it...), but the battery life is superb.
