Re: Raspi with Case and display - what can you recommend ?

Hi there. If you just want a display and a case, I can suggest: https://thepihut.com/collections/raspberry-pi-cases/products/raspberry-pi-official-7-touchscreen-case for the case and then get an official touchscreen display: https://www.modmypi.com/pis-and-peripherals-1139/raspberry-pi-7-touchscreen...

Re: Robot Navigation - Mapping or Map Reading

Hi. I'm one of the Pi Wars organisers. We do indeed reveal the design of the maze in advance. There's several ways of completing it: 1/ Ultrasonics on multiple sides of the robot to detect the walls. 2/ Pre-encoding the robot with a route with distances and angles. 3/ Add up to 6 'targets' such as Q...

Re: New Raspberry Pi model 3B+ 1.4 GHz, 330Mbit Ethernet, 802.11ac, PoE

Depends which case. Official Raspberry Pi case fits perfectly. PiBow doesn't, however, and they've launched a new version.

Re: Odd Camjam engine behaviour

That's all true. However, most people find the Pi's performance to be good enough in that respect. I was suggesting improvements to your approach rather than a wholesale change.

Hi again. So, two things to do: 1. Try it with 4 x 1.5V AA batteries rather than the rechargeables, just in case it _is_ that, but I doubt it because we know that others have used rechargeables without a problem. 2. Can you take all your code and upload it to Github so I can see it completely and cl...

Hi. Mike here from CamJam. If the script from the worksheets works correctly then there's nothing wrong with the hardware. There must be, therefore, something at issue with your software.

Re: Why no Pi Zero with full sized connections?

I'm a bit curious about this one. I've been doing some math, comparing the Pi Zero to the Pi 3, and it seems that after you buy all of the adapters, hubs and such you need for many projects, a Pi 3 is just about the same end cost but a lot more convenient and capable. My question, why isn't there a...

Python, using the GPIO Zero library would seem to be appropriate.
