the case or enclosure of all my diy projects is generally the hardest aspect to get right. 3dprinting has opened up both access to the design tools and designers via sites like thingiverse. and you can get jobs printed to order. it took me 5-10 minutes of watching a child orientated utube on tinkerc...

this should get you started with the light sensor, copy the code/example and get it working and then step through it and try to follow whats going on.. the penny may not drop instantly, have a coffee and return to something else and keep it on the back burner for a while.. https://learn.adafruit.com...

Bluetooth covers a number of protocols, afaik most devices that make and maintain a consistent connection during a session use the more power hungry aspects of Bluetooth. BLE the low power variant of bluetooth isnt used for connecting to devices for a maintained connection more of a connect communic...

Yes any Pi could do what you want. however there are alternative options which could easier and cheaper to implement. For example check out the stc1000p+ project over on github, its a reflash firmware solution to overwrite the stock firmware in the very common and dirt cheap stc1000 temperature cont...

as suggested above python is a good scripting choice on a pi to stitch your system together. you should be able to fine example scripts accessing the output from a usb bar scanner, for the coin acceptor?? a search based on make/model may provide similar examples.. Start by getting the examples up an...

if you go the route of smart plug with montioring, make sure the plug can handle the amperage of the device. most are only 10A loads. and of the 15A - I'm not so happy about the reviews - seems quite a few like to catch fire! - so now I need a smart fire detector also? will have to keep an eye on t...

If supplied by mains electricity may i suggest a more out of the box solution, a £10-20 smart socket that monitors power usage can be reprogrammed with your own or a public project like Tasmota https://github.com/arendst/Tasmota/wiki.. Many smart devices use the same core h/w :) Any Adds that mentio...

I did install some software that would decode the signals from my three channel wall plate. The software will not decode 300 MHz however. Maybe the tasmota software has more options. ?? think about it.. you have h/w tuned to receive signals at one frequency is it surprising it wont pick up signals ...

to paraphrase "I consider it unfortunate that you spent all that money before you posted" Granted when you buy a product like ring you do get a joined up solution Today.

#1 tasmota is targeted at esp8266/5 soc devices , an esp32 fork of the project was started but if it has been maintained or not needs looking up. to turn on a device with the mqtt Topic (ID) "Light-Switch" publish a cmnd/Light-Switch/Power1 ON, or cmnd/Light-Switch/Power1 TOGGLE mqtt Topic payload m...

you might want to consider using one of the 2 pi puters to host a mqtt broker like mosquitto. then you can use mqtt to publish button press events triggered by your button station (looks like an IR remote btw..) http://www.steves-internet-guide.com/into-mqtt-python-client/ and if your lighting app i...

i think the pi-0-w wifi connection would be the main bottleneck rather than the usb-sata hdd/ssd interface.

PhatFil

That depends..

Post your code

BUT!! Please do use the code tags in the editor menu

Code: Select all

so your code looks like this and retains its formatting which
     can
         be
             crucial sometimes

If you are talking about the cheap Chinese 'radar' modules https://www.ebay.com/itm/RCWL-0516-Switch-Microwave-Radar-Sensor-Module-Induction-Human-Board-Detector-TR/352666551849?hash=item521c908629:g:HWEAAOSws3lc3ln8 , first they are not radar at all but sloppy 3ghz doppler detectors.

use the keyword "DUPONT" along with M/M, M/F, or F/F in your shopping searches for 10, 15, and 20 cm ribbon cables of jumper connecting wires. the male dupont ends will plug into breadboards and the female headers sometimes used on the Pi gpio header, and the female ends accept male ends and can fit...

Thanks for the info. I understand few of the acronyms mentioned. It seems a lot of stuff for the small embedded project I was thinking of. I need a few days to consider if I want to go down this path, I may stick to the Arduino... Sorry not my intention to baffle or confuse.. SSH Secure SHell https...

SSH and VNC were both mentioned earlier in this post, Has the OP rejected the idea of using an existing pc to take remote control of the pi cli via SSH or the Desktop environment over VNC??? In both cases the Pi once on the local network can be used headless without extra keyboards mice or monitors....

Thanks for answering! If I understand correctly your point, I won't be able to operate this remote with a couple of soldering point (plus a breadboard and jumper cables I already own)? At first sight, it looks rather simpler than capturing and re-emitting codes that the remote's chip can already pr...

rather than hack the device, an alternative approach could be to invest a couple of quid or dollars in a pair of 433mhx rf Tx and Rx Pcb modules. https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwj2ioLL8unlAhVNsO0KHXGUA3AYABARGgJkZw&ohost=www.google.com&cid=CAESQOD2Fj2VR3twbGkgjS0K469S4sbd...
