A4988 driver module sleep pin
  • The charge pump not being stable can mean several things. If it's not where it should be (it won't be) the high side fets won't turn on all the way, causing loads of excess heat inside the chip. This also may never recover, depending on the duty cycle, and then that chip will burn up/let the smoke out.

    Essentially, the charge pump capacitor has a set of circuitry that brings the low side of it low, lets it get 5 or 12v, then floats it up to the voltage rail, to turn on the fet hard. If it's only partially on, the fet has a resistance that is too high. (The high side of the capacitor usually has a diode to charge it)

  • Nate Silver's model for the 2024 election is out, currently predicts a 65% chance of a Trump victory.
  • Same models from 2008-2020, at this point in the cycle, it had Hillary winning, and Biden winning, both by a decent margin.

    I think it depends what the campaigns do with this information. Coast, or fight harder?

    Vote vote vote. (Just once though).

  • Configurable OpenSCAD calendar
  • So if you want to print a calendar for 2077, rest assured that the model will calculate the correct day for the 1st of January (it's Friday, btw).

    On one hand, I'm assuming that you wrote proper code to figure out what day each year starts with.

    On the other hand, I imagine that you set it up Friday, a constant.

    Nice work though!

  • Friday's pie (taco)

    Had leftover taco fixings, so we made a taco pie this weekend. A bit of the pizza had crushed nachos (kid requested). Overall, a solid pizza.

    (homemade) Tonkotsu ramen, with pork, egg, corn, spinach, and enoki mushrooms.

    This was yesterday's dinner, the last of my freezer pork (this means I get to make another batch)
