> According to Richard, the issue began when he couldn’t always remember to start his car on cold mornings. Sure, you can automate something like this with Alexa, but he needed the car to start itself without the need to remember the command. That’s where Pi comes into play. Using Home Assistant, he’s created a system that will trigger his car to start on mornings when the temperature gets too low.
> FS: Unfortunately, on my way to university, there’s always been this sort of divide between design and technology on the one hand and the sciences on the other; if you could do the science bits, you didn’t do design and technology, you had to just stick to the sciences to get the points to get to the university that you wanted to.
> Now that I had my degree, I was still enjoying the design and technology. I started to build props [for the Science Museum] and got approached for lots of freelance work where people from other organisations were asking me to build things.
> Your UK school is invited to take part in a project to help us evaluate students' attitudes to coding and how they are impacted by Code Club.
> I used an Estes D12-5 engine for my rocket. This is a single-stage engine with a 24mm diameter, designed for rockets with a maximum lift weight of less than 270g. Perfect for the Estes Green Eggs.
> As soon as I stumbled across the Rockit RP2040-based model rocket flight controller on Tindie, I had to have one. Rockit (Rocket Operation Computing Kit) is a compact and inexpensive flight computer designed by Dan Invents from Finland for small model rockets. Among its many features, this board has an altimeter, accelerometer, and temperature sensor, all of which record data to a microSD card for post-flight analysis. Dan did a fantastic job with this board, and even included a 5V boost converter with 2A current output in order to control servos for more advanced rocketry. Alternatively, it can be used to power a Raspberry Pi and camera: now we’re talking!
> The researchers designed S-BAN (Shape-Based Assistance for Navigation) to work with existing GPS navigation systems, such as Google Maps on smartphones, but to provide a better user experience. The S-BAN device looks like a small remote and the fore end actuates in two dimensions. It can move forward and backward, and pivot left and right to guide the user. If, for instance, the user needs to make an immediate left turn, it will pivot left. This lets people with visual impairments navigate through touch and helps everyone else walk with their eyes up instead of focused on their phones.
> Mark your calendars: May 23rd-25th we’ll be at SPS Italia, one of the country’s leading fairs for smart, digital, sustainable industry and a great place to find out what’s new in automation worldwide.
> So much of the research and development in the area of haptic feedback focuses on universal devices that can create a wide range of tactile sensations.
