Re: Raspberry Pi 4 Thread - general discussion

Don't understand why they're taking it in this direction, I've never once thought the rPi needs more power. I'd rather they focused on better interfacing; analogue inputs, selection of pu resistors, power buses, protection circuits, level shifters, chip sockets etc; stuff that makes it easier to hoo...

Re: STICKY: Pi 3 A+

Surely they'll give us a Pi 3.14 before the Pi 4?

Re: PySimpleGUI - New package for building custom GUIs in a few lines of code

Looks good, I'll have a play with this later. Couple of questions after a brief scan through the guide: 1. Does BorderDepth=0 remove all the 3D bevels? Flat interfaces are in vogue these days. 2. Could you add a function to set the form background to a bitmap, with all the elements having transparen...

Re: super accurate distance measurement with rPi

I've been pointed towards the VL53L1X sensor, for example the RB-Pol-633 board:

Has anyone managed to hook one of these up to a rPi? Thanks.

super accurate distance measurement with rPi

Hi, I need a rangefinder to use with a Raspberry Pi to measure the distance to the surface of a column of water moving up and down in a 15cm diameter 3m long perspex tube, in an indoors environment. The rangefinder would be positioned above the tube. I could either measure the distance to the surfac...

Re: rPi as a SSL web proxy

Yes it's mitm but you install a certificate on the client to allow it.

rPi as a SSL web proxy

Hi, I'd like to use my rPi as a web proxy with ssl inspection to modify incoming web pages from a https web forum, the idea is to create a script to parse the html and filter out "blocked" user content. I found a site describing how to recompile Squid for SSL but it didn't work, various links in the...

which 4x relay board

Hi, I'm building a project to control 3 devices (12V/4A,12V/1.25A and 12V/1A) via a relay board. I want the relays to be HIGH=ACTIVE. I bought a £5 Chinese Keyes Funduino board to prototype with and it actually works ok, but has no CE mark and I'm worried it may be unreliable. At the other end of th...

Re: 5V Relay, Power through Pi or with separate source

Watching this with interest as I need to control a pump and some valves via a 4x relay board. If you haven't got a degree in electronics the simplest approach seems to be buy a cheap Arduino clone off eBay and use the Pi as the brain and the Arduino to handle 5V I/O; you can interface the Pi and Ard...

Re: controlling Arduino from Pi

Nevermind got it working, just needed to use pip3 rather than pip to install it for Python 3 :)

Very impressed with nanpy, works well.

controlling Arduino from Pi

Hi, new to Python and I want to control Arduino pins via my Pi2. I was about to embark on writing some serial comms but found nanpy. It works ok in Python 2 but not in Python 3, and of course I'm using Python 3. Also tried PyFirmata but same problem. I want to read and write the digital pins (0-13),...
