Your Raspberry Pi Projects

I am a big fan of SBC's so here goes,

Rpi 2b - Osmc (Mine)
Rpi 3 - Osmc (old man downstairs)
Rpi 3 - Osmc + Dstv now (old man upstairs)
Rpi Z - Camera viewing 6 cam's
Rpi Z - Camera viewing 9 cam's
Opi Z - Nas
Opi Lite - Notice board, print server and Google home (mostly controls Kodi and some lights)
Opi Z - Toy board for testing
Esp8266 - Wifi repeater
Esp8266 - Weather station
Esp8266 - Router changer (I have Rain unlimited 11pm -6pm and then Afrihost Rain for peak, it swaps them for me)

Every time I read through this thread I get jealous of the project's and coding abilities!! :)
 
Projects I'm busy with,

Esp32 camera module , either to view the generator and control board or a hi-tech tank level viewer (or perhaps both?).
Esp8266 or Rpi z or Opi z three temp sensor display and logger that works offline as well as posting (perhaps to google sheets) online as a backup.
Esp8266's -Outdoor microwave sensors displayed in real time on an internal webpage for early warning of nighttime visitors.

Coding ability and life getting in the way a wee bit.

Is that a timed switch that controls power to the routers or is the esp8266 a repeater that switches between the routers and is the main AP?

Yes, very simple and low tech. Both routers setup identically single cable each to the main ethernet switch and the relay switches power to either one.

How is stability of the zero w on the USB power?

As it is running a minimal headless OS with pihole it does not need a lot of power. It has not yet let me down. As with any PI-Zero it takes a bit longer than the normal Pi's to boot up but it does not cause me any hassles.

I think I love SBC's more that you :)

8 x Wemos ESP8266 temperature sensors
1 x Wemos to measure water flow
1 x Rpi running Flight Radar 24
1 x Rpi alarm controller running python
1 x Rpi weather station
1 x Rpi DHCP/DNS Server
1 x Rpi CCTV Monitor
1 x oDroid OpenHab controller. Links to telegram, Alexa, sensors, alarm sonoff etc
1 x Rpi with OSMC
1 x Vero 4k with OSMC
4 x Vero 4k doing nightly OSMC builds
1 x STM32 board for Atari 2600 games off SD card
1 x Arduino for ZX Spectrum games (TZXDuino)
1 x Arduino for Commodore Vic20/64 games (SD2IEC - load tape games off SD)

And a partridge and a pear tree :)

Tell us a little more about the early warning microwave system
Click to expand...

What my plan is,
-RCWL-0516 Microwave Radar Sensor RCWL-0516 is a mini doppler radar microwave motion sensor module which can act as an alternative to a PIR motion sensor. It will continuously output the high level ..R45.00
-Esp8266 (or 32 perhaps) connected to above board, running a web server.
-Esp8266 wifi repeater, to get wifi out in my fields.
-not sure what to use here, but something to collect and display the info.(perhaps an existing Opi on my notice board)

Principle - I have tested the microwave boards and they seem to work fairly well outdoors with a range of about
4-5m as long as you keep the esp about 300mm away from them. They would run either in deep sleep or low power mode monitoring a high or low pin. This going through the repeater would come to a map on a notice board? type of setup showing me active trips and perhaps trips in last 5 min's or so(perhaps red and yellow dots ). Therefore with them placed in commonly cut areas in my fence, so when the dogs bark at night I will know where to point my pistol.

My coding abilities have however put this on a back burner while I practise some, as I don't want to have to refresh the page manually and my attempts at a database were horrible (being polite).

Maybe use a cron job to do the refreshing for you - just a thought... I use cron to run automatic weekly updates and run a wget command every 15 minutes to keep my IP up to date so I can access my cctv remotely via a domain set up for it.

You can use crotabguru to get the timing right.
 
Good thought and maybe something to look into. The way most people are achieving what I want to do is through Java or php or using mysql to keep things in real time.
I got very frustrated when I couldn't make them work for me but it is something I want so when I get a chance I will carry on with it.
What do they say, "why make it easy when it can be made difficult" :)
 
My wiring became a mess, so this is the "neat" version. :cautious:

It's a Pi Zero with 32-port expander to use as an additional alarm. I'm covering each side of my house with a PIR sensor and strobe light.

With a strobe light on the side where movement was detected, that's an additional deterrent and I'm going to configure some modes like silent / short beep / xmas disco party.IMG_20181222_113251_2.jpg

Nice! How easily are they triggered by pets?
Click to expand...

I am glad there was not a youtuber around that day!:eek:

The little dog (Yorkshire cross a bit bigger than a cat) did not set it off at all and bounced happily through the area, The big dog (boerboel) was not co-operative during the experiment but seemed to trigger it perhaps a third of the time. So I'm happy that the spring hares and night birds won't be a problem as the dogs are in the innermost area and not where they would be placed.
That being said they are temperamental (the boards not the dogs:)) ie. they need time to map the surroundings (+- 1min) are fussy about power supply, the radio signal (from the esp) affects them so there is plenty that needs to be ironed out before they are foolproof.
 
I have thought of just putting a flashing led on them and seeing what they do out there, but then it means my OCD would kick in so I would be walking through the veld all night being eaten by mosquitoes! =!good_idea
 
My SO was bored so she made an alarm system. It has a touch screen to arm and disarm per sensor and globally. It communicates with a linux server on the internet and has her own made app on the phone to control it from wherever we are.

She started 2 days ago and that where she is now. She thinks its very funny to track my movements.

Whats cool about this alarm system is that we can use old legacy PIR's.

Wow!!
And here I am struggling with the simple stuff!!:ROFL:

Shes a java developer with electronics background. I dont know anything of this stuff. Now she says something about maven. Im like yea hes a cool dude. No idea wtf that means but I nod and agree.

I agree, he is a cool dude!:) (no idea what maven is)
You must send pictures. (of the project, not her):)
