Re: RPi Cam Web Interface

Latest version has a feature request added to the download / preview page.

2 buttons allow selected captures to be locked and unlocked. Locked captures are read only and won't be deleted or purged. You can see which captures are locked as their thumbnails do not have a little delete button.

Re: RPi Cam Web Interface

4 out of my 5 deployed camera run on Pi Zero (original) using USB to LAN interfaces and they have never crashed. They are in use 24/7 and have been running for several years now. Only down time has been during power cut or when updating software. I also run dev cameras on Pi2 and 3b without seeing p...

Re: How to get carrier frequency of the infrared signal using LIRC

You can use a regular phototransistor (e.g. BPW85) to get the raw data from a remote control. Connect emitter to 0V, collector to GPIO and 10K resistor, other end of resistor to 3.3V You want to hold the remote reasonably close to the phototransistor to get a clean signal, and you might want to shie...

Re: [Questions] Pi in old radio cabinet. Possible?

A single Raspberry should be easily capable of running all these functions together. I would use a web server based Security camera set up under standard Raspbian to make it easy to add on the other functions. On a Pi3 these take only a few % of the CPU as the GPU is doing most of the heavy lifting....

Re: Switching LED array using R Pi and MOSFET

Your circuit won't work, as its essentially a "drain follower", the LED's strings (including the resistor) won't get 12V, they will get 3.3V minus the gate-drain voltage needed to open the FET. Instead you should connect the drain to GND, and attach the LED's between 12V, and the source of the FET,...

Re: How to detect an old style wired doorbell only - nothing else

Personally I'd use the 10V ac to drive an opto. I would do the same. If the zener diode get damaged / broken, you don't blow up you (expensive) controller. Using an opto is a good method. I used the zener method as it was to hand, simple and with the resistor limiting any over-current. Zeners are v...

Re: How to detect an old style wired doorbell only - nothing else

Did you know that you are providing approximately - 0.8V to the input of your ESP8266 ;) . Instead of this: A resistor / zener diode clips this so a 0 - 3.3V 50 Hz pulse is fed into a GPIO pin. However, I find you code interesting and I need to take a closer look at it. Yes. That is true. It was lo...

Re: temp sensing of 12 thermisors is this the right forum

This is certainly possible. To measure the thermistor each one needs to be fed via a fixed resistor from say the 3.3V supply. The voltage across the thermistor can then be used to calculate its resistance and therefore its temperature if you know the characteristics. You need a multi-channel ADC add...
