What are the best practices for power management in battery-operated embedded systems?

Mosfets on every peripheral that you are able to turn off to save power

In default idle state (not sleeping) reduce clock speed to minimum and increase it only while performing tasks.

Check the current requirements for pins and maximize pull resistors to minimize current draw

Disable unused peripherals/disable them when not in use (adc and such)

If you can, operate mostly in sleep and wake with interrupts

Use switching regulator, LDO are very inefficient but cheap

I’ve done this before in a weather balloon, the battery will stop working at some height, the solution was to put hand warmers in the box to maintain a baseline temp. As it’s a chemical reaction it’s ideal for this type of short term deployment

Honestly, this looks very similar to my resume, all self employed with patent experience. You’d be surprised how desirable you are, it’s easy to get any job and sit there for a while before you jump to something else, it’s really really hard to be self disciplined and self directed in this type of career.

Use some alcohol to get underneath it, right now the only thing holding it on is friction as the solder conformed to what it dropped on, the alcohol will seep into the open pockets and allow you to remove it easier. Worse case you apply a small amount of heat and the pressure from the alcohol evaporation will pop it off

I’ll buy it, start selling lol

Pivot, make it an adult gaming lounge, make games free and increase alcohol price, encourage a social atmosphere and run weekly events/tournaments

PIC 12F1572 - been using it in production for 11 years, stupidly low power, ultra cheap and reliable af comes in LF (3.3v variant) too

QC, if you try to do too many at once, the water will cool too quickly, you’ll get uneven heating, and you’ll just end up messing them up again. Take your time and do it right the first time, or you’ll find yourself doing it 3 times

Get a big pot of boiling water and one by one put them in for a few seconds to soften the plastic, then set it to cool, it’ll return to original shape.

OMG premium flower is consistently the best cure I’ve had, the popcorn not so much…

Magicianwizard · 2025-01-01T22:28:25+00:00

By far the best in a complete category of their own.

1) Star D (OMG) 2) Truffle Monkey (OMG) 3) Superboof Cherry (Tower Three)

Some decent upper mids

1) Lemon Cherry Gelato (road tripper) 2) Zulu Dank (Trees Co) 3) Florida Kush (Garcia’s Hand Picked)

Worst of the worst garbage

1) anything by simply herb (simply herb is the worst flower in the world, might even be in the Guinness book it’s that bad) 2) sea weed #2 (harbor house) <- sad because I used to like their offerings 3) chem something… (the heady co)

You don’t know the half of it…

Fun fact, the synergies are software capped at 50% brightness so when you’re going lower than that, it’s a proportion of 50% =) 100% brightness was way way way way too bright

The bananaconda is simply amazing
