To avoid this issue with my pi3-nas, and stop the hub psu maintaining power on the Pi board I simply snipped the +5v line at the hub pcb, being an older hub with an old square usb B? socket it was a simple task easily undone if needed, with a smaller usb micro device it may be easier to hack into th...

Dont overwrite your Stretch system sd card, get a new one and keep the stretch card as a backup/fallback reference..

I had fun and games with false positives from the usual pir modules with my attempts at a room multi sensor.. Forums and utubes were full of suggestions to shorten connecting leads, lengthen connecting leads, distance the module from the wifi transmitter and sources of pcb heat, twisting wires , iir...

Hey PieLover.. Yes as said above you could.. But perhaps these projects which use similar Off the shelf BLE sensors might give you a clearer picture of just how a Pi could be used very easily with little effort beyond a bit of cut and paste at the cli to interface with such devices and use the senso...

manually removing the card from the pi and inserting it into the PC with an USB-adapter what means "headless" ? I don't know python , just DOS , a bit Linux headless refers to a puter without any direct i/o attached. No monitor or keyboard/mouse, connected to via remote access (ssh/vnc). Pi compute...

Similar 'dead' headless pi-0 devices on my network had me running in circles for a while.. var/log/syslog etc wasnt enlightening, and provided no clues to a problem. Eventually i tried to reboot the router/AP instead of the PI, and on its return to service the Pi was available without any interventi...

YOU dont Need NOOBS to install raspbian onto your Pi but you cant overwrite the system sd card in a pi while its in use either.

You will need a usb/SD card reader And with one you could on a working pi with a network connection download and flash a raspbian image to a new/2nd SD card.

You cant expect any temp sensor to be really accurate out of the box without some calibration. For that you pay a premium for a certified and tested device.. a 2 point calibration is good enough to validate most sensors and close to 0C and close to 100C are temperatures you can easily approximate wi...

Good Luck.. especially with the hand eye coordination with a large offset view.. Its a knack some find easier than others..

Tibbets has had 20 to 30 implants, almost all of them self-insertions.

nudge nudge wink wink..

so now we can have Internal Area Networks too

I'm sure such a thing exists, but I've not been able to find clock hands that can be positioned by pi or microcontroller. I've seen plenty of analogue "radio controlled" clocks that set the clock hands based on time from the MSF signal...but have no idea how to find a set of clock hands I can contr...

I find vnc fine when needed to access my headless pi-0-w systems and a gui interface. the arduino ide should work fine via vnc, its not as if many folk speed type when coding, (tv hackers excluded of course..) its either cut n paste or ponderous typing usually ;) But if you do type at speed typist r...

I have an old project (long overdue for an update) using similar 433 mhz rx and tx modules. with a 12v power supply to the tx module and antenna attached to both the RX and TX modules i can recieve data sent via the offset fine protocol on a 5v arduino datalogger 25m distant from the brewshed.

What sort of bell is being rung by the doorbell?? IF its a mechanical bell and hammer you may be able to wire a passive circuit using a magnet superglued to the bell hammer with a reed switch or similar to detect the magnets movement and ringing of the bell.. same result but no need ti get involved ...

Are you trying to share the root of the disk? If so try creating a directory in the disk root to share. if successful then move the disks contents down one level into the new directory. when setting up my pi/samba nas i found i had problems when trying to access the root of shared disks, but sharing...

asuming you dont use a gui at all for setup after setting up a pi just dump the cli history to a file and you have a roadmap for the next identical set up or restore.

i agree a casual glance over the docs i found for the command line tool dont talk about the same event/recipe config?
perhaps more expert advice can be found in more specific forums/lists?

Not exactly simple is it? perhaps a diy solution based on hosting a mqtt broker and a $2 esp8266 with a rgb or neopixel led attached would be easier to build from scratch. 8.1.

sorry thought you were asking for where to get and install the tool which is in the above link along with links to using the gui and cli versions of the tool.

Will that wiring cause interrupts to be triggered? Do you advise 5V+divider+SW pull down or GND+SW Pull Up? OR JUST USE THE +3.3v pin as the +v source like everyone else.. Only when using more sophisticated modules that provide a 5v signal should you need to supply 5v and use a voltage divider or l...

you can only read new data to which you subscribe as and when its published. Mqtt brokers can be configured to retain payloads but that will just provide the last data published. You could publish on demand by responding to a Request mqtt publication but thats counter intuitive to how the protocol i...
