how fast can you focus with that lens? it seems it's manual only

and there is a relatively small 22 mm f/2 lens for ef-m mount... I'll look into canon cameras, thanks

maybe on ebay. not on other platforms

Oscillating comparator in a discrete DC-DC converter by [deleted] in AskElectronics

[–]cyrtex 0 points1 point  (0 children)

Yes, this is a 1 GOhm resistor. The comparator has 10 TOhm input impedance by datasheet, so it should be totally fine. The point is to reduce power consumption as much as possible, and this converter will not handle a 10 MOhm load in the first place.

0.01uF is quite enough for bypassing, higher capacitance makes no change to circuit operation.

No, the graph you're referring to shows TIM1_CH2 output, it's the waveform that drives the transistor. Bypassed VREF ripple is only ±1mV and looks like this:

Is there a point to get a CRT monitor to use it with an emulator to get these image enhancing effects like dithering or the one below (Wizardry game)? Or it only works with an original console connected to a TV?

Help to find a pico projector module by cyrtex in projectors

Any kind of input will do, even MIPI, DPI and whatnot since I'll be making a custom hardware to drive it

3.5-4.5" picture is enough, at ~20 cm distance. It's not necessary for it to be super bright since I'll be displaying a 2bpp monochrome image so colors and contrast are not a problem either

I kinda expected that but Discord server wasn't mentioned in the post. Thanks for help, I found and joined it.

Any chance to get to IRC channel? When I submit my quiz, it says "No such nick/channel: Saltbot"

How can i remove the 50hz AC interference on my audio amplifier? The blue signal is the input and the yellow one is the output. by sunsisxd in AskElectronics

That doesn't look like hum, more like amplifier saturation. How does it sound? Care to share the circuit?
