The Desk of Ladyada - Spooky Stemma Seesaw Sunday!
70We're finally getting back to all the seesaw boards we re-designed to use attiny817's now that the breakout and tester code for this family is done! Here's two designs, one is a slide pot + 4 neopixels. The other is for 'arcade buttons' with built in LEDs. We're mostly focusing on UI elements that can be used to make control surfaces. We're also trying to stick to a standard sizing so they all have similar mounting holes/shapes. We're really liking this family of chips, and have lots more QT boards we plan to design around it.
The Great Search - Mini 5V Charge Pumps

Sometimes you've got some 3.3v powered circuitry and you just need a lil bit of 5V power for some LEDs or to level shift to 5V circuitry power. You could go with a boost converter but usually you need a diode, inductor, maybe even a feedback resistor set. If you only need ~50mA you may be able to get away with a charge-pump. These low-current boosters are not as efficient as DC/DC style converters but they are very simple and cheap, only needing a capacitor or two to 'double' the input voltage and then regulate it down.
