Re: Making an HUD

A bit late to this, but I built a pi zero HUD a couple of years ago and use it every day. Python code reads the output of a GPS dongle and displays it on a two digit 7 segment LED display. The display used a library of functions to convert the numbers to binary words for the display. I rewrote the l...

Re: Yet Another Raspberry Thermostat

Before replacing my thermostat, I wanted some data to see what the temperatures were like in my house. Each room has a pi zero W with a DS18B20 sensor, the kitchen pi also has an outside sensor and the living room aquarium already had an ambient sensor. Each pi runs a python script every half hour, ...

Re: Temperature trending with DS18b20

I would be tempted to record all temperatures in a MySQL database. This would give an opportunity to experiment with real time data, using queries such as averaging over differing times. If you recorded timestamp, temperature, any heater/pump switching, graphing the output would give you a good visu...

Re: New to Pi... Is this Trail Cam project possible?

Re: STICKY: The projects list. Look here for some ideas.

Re: RearPi - Use your Raspberry Pi as Rear View / Backup Camera and Dashcam

No, the button doesn't work, anymore. But the voice command is just so much more useful.

Re: trigger phrase

I've had a go at using the Snowboy trigger.

She now answers to " Wikibitch"!

Just so we know she has triggered, she says "yes?" before we ask a question.

Much more useful than having to clap, or it triggering on a door shutting.

Re: Best questions to ask AIY. ..

When you ask about coffee, it tells you to use an Aeropress, which is the correct answer.

It then makes two mistakes

It isn't 1 spoon of coffee, it's 12 grams

It isn't 60 seconds wait, it's 90 seconds

I'm sure that will work on the PiZero, but it doesn't seem to show how to stream it to the web.

The link I gave above logs the temperature to a SQLite database.

at the bottom of the page is another link which shows you how to read the database over the web.

Re: Button sensing in the background

I did use sudo. I tend to sudo su every session. Then I used crontab -e to put the line in.

According to the log I posted, it did the job, but the button logs are blank and the button isn't being detected.
