  1. Oh you mean like a purge block? Why not just use the default? Otherwise I guess I’d just print benchies of varying size lol.
  2. The Quick hot air stations are really good. I think it's the 957DW+ that I have in my lab, can't beat it at $100.
  3. Honestly I would just try to find the footprint on SnapEDA.
  4. ya she's fuckt m8. Inside that chip was a bunch of silicon that is doped with probably arsenic and/or germanium (meaning individual atoms of dopants mixed into the silicon lattice). This silicon and dopant mixture was arranged in a very specific configuration to hold a matrix of individual bits. All of this was carefully sealed in black epoxy, with tiny wires connecting the matrix to a grid of contacts on the bottom of the chip. These were solder points that attach the chip to the board. At these points was a tiny fleck of solder, but since the RoHS standard, there is no lead in mo
  5. They're probably referring to these. Some power resistors are basically big blocks of cement (for its thermal mass) and some are normal resistors encased in a heatsink to dissipate more heat. The latter are common in automotive LED headlight conversion kits because LEDs don't pull as much current as a normal lightbulb, so you need to add a parallel resistor to make the headlight computer think that there is in fact a light bulb connected. https://www.google.com/search?q=power+resistor&source=lnms&tbm=isch&sa=X&ved=2ahUKEwi5wqnO59nyAhXcJjQIHXLhDSgQ_AUoAnoECAEQBA&biw=153
  6. So the power rating of a resistor is the maximum power that resistor can dissipate before it burns. The power dissipated by a resistor is equal to the voltage dropped across that resistor multiplied by the current flowing through it. Using some Ohm's law substitution, we can also find that the power dissipated is equal to the voltage dropped across the resistor squared divided by the resistance, or the current through the resistor multiplied by the resistance. In your 10w parallel circuit, assuming the voltage remains constant, the two resistors will each pull the same current and
  7. It’s weird, in practice they do the opposite. When combined with rev hang from modern engines, it’s much harder to shift smoother and removes a lot of feel from the clutch. On my golf you could either shift smoothly or shift quickly, but never both.
  8. But they don't. If they're supposed to slow down the slave when the pedal gets released too quickly, they fail. At least in my golf, all it did was make it very difficult to shift smoothly and quickly at the same time. I bought the car in March having maybe driven stick for 200 miles, put 5000 miles on it since then, and it really just felt like I was driving in hard mode for no reason. I don't get it.
  9. Are clutch delay valves common in modern manual transmissions? I took the valve out of my golf last night and the car is so much easier to drive now. Really doesn't make sense to make a car drive objectively worse from the factory.
  10. The Art of Electronics is pretty widely regarded as the holy text of practical electronics. It covers the underlying theory that’s important for understanding the interesting stuff. But it does place emphasis on more practical knowledge and circuits.
  11. Iirc there’s a new pocket nc that is more rigid than the standard, might fit the bill.
  12. My UT210-E has a phenomenally accurate DC current clamp. I truly wasn't expecting it to do so, but it was accurate to within 100mA iirc.
  13. Pocket nc would do. Otherwise I think you could get a tormach could be had for under 10k.
  14. Good PCB layout is generally accepted to be about 80% layout and 20% routing. Good designers group and orient components on their boards as best they can to simplify trace routing. Every PCB layout tool I've seen and used displays what's called a ratsnest, or a network of straight lines denoting which component pads are to be connected to each other. It's built on the board's netlist, but it shows designers what needs to be connected where. Good design minimizes the number of crossings of ratsnest lines in a given layout, but as boards get more and more complex, it becomes inevitable. This is
  15. How is Lulzbot still alive? Their latest option is $1300 in a configuration that lets you actually print something out of the box and it's less featured than a Prusa. I don't get it. Their pricing makes no sense. The market should have killed them along time ago.
