Re: Linux Journal

I just read this: https://what.thedailywtf.com/topic/2433 ... uck-s-sake
reminded me of what i still think linux is like (and apparantly sometimes it still is like that ^^')

Re: RGB lightsaber

Just gonna vent here a bit XD Took me Waaaay too long yesterday to get the filestreaming from fat32 completely working (was wise enough to write a proper test so i could find any and all errors, and boy, i found them all XD). Somewhere in the future i want to come back to this as i finally have a go...

Re: F405 & F411 versions of the BluePill

that's indeed one of the annoyances in KiCad... none of the canvas modes are complete yet. I hope for KiCad5 they'll resolve that.

Re: F405 & F411 versions of the BluePill

Is it really such a major problem if 5V is connected directly from the USB to that pin? Is this just to keep it 100% compatible with the BluePill ? Is it just protection if someone powers via 5V and connects USB? I think this may just have to be a limitation, that it’s not practical to have the pro...

Re: F405 & F411 versions of the BluePill

I think it can be made to fit, but virtually all the other components between the USB connector and the MCU probably need to be moved, and a load of tracks rerouted. I am not sure why this diode is so much bigger than the FET it replaced. I know that the FET was in the circuit the wrong way around,...

Re: F405 & F411 versions of the BluePill

seeing rogers screenshot, i'm wondering if we can't tweak the footprint a bit with slightly smaller pads. it's probably a bit worse, but if you see the 3d model on them, they're quite a bit bigger than they need to be.

Re: Linux Journal

<....> I have 4 different RPi boards and have yet to find a project which they are suitable for. <...> Back in February of this year, one of the first projects I built on a RPi was a live video webserver. The camera API is really rather robust. https://elinux.org/RPi-Cam-Web-Interface and https://w...

Re: F405 & F411 versions of the BluePill

these ones are probably pretty much perfect, but way too expensive -_-

Re: F405 & F411 versions of the BluePill

Can we get the same spec diode in a smaller package, as is a real squeeze getting the it to fit Or do we need a 1A diode. Will a 500mA one do ? This is questionable! We chose the main LDO to be able to deliver 1A, as the STM32F405 already sinks 450 mA max itself; we added some room to power externa...
