Our L293 based motor shield had some problems! How do we diagnose what the problems are and create a better design? This final tutorial, will explain how we went about troubleshooting the issues and creating a better circuit to be used in version 2 of our design. #arduino #uno #motor #shield #debugging

Following our article on how to design your own Arduino motor shield, we have written a companion piece that explains how to create your own Arduino library. Our explanation focuses on all the things that the beginner tutorials don’t cover. #Arduino #UNO #STEM #nexgencodecamp

We recently published a new article about writing your own flight controller software.

Why would You?

It is a reasonable question. There are a number of Open Source and proprietary quadcopter flight controllers with firmware available. The problem is we want to use an Arduino board, to fit in with our other training programs. As soon as this becomes a constraint your options are very limited. In fact, your only real option is to write your own. So here we are.

Initially we attempted to port BetaFlight across to the Arduino Portenta H7, as this is designed for STM32 hardware and we know that writing your own flight controller firmware is tough and time consuming. We managed to get BetaFlight to compile for the H7 but because Arduino’s use a custom bootloader which is located right where BetaFlight normally sits in memory, flashing the firmware was problematic.

This app allows you to visually program a flight plan for the Tello Drone and then upload it to the drone for execution. You can also fly the drone manually with the app if you wish. Real time telemetry from the drone is displayed on the glass cockpit.

Tello is a mini drone equipped with a HD camera that is manufactured by Ryze Robotics and includes a flight controller with DJI smarts.

We access the Tello API by connecting to the airframe via a WiFi UDP port. Once a connection is in place, the drone is controlled using simple text commands.

It is available on the Apple App store. Download FlightPlan.

My wife requested this latest app.

Mindful is about helping you find a way to become more present and less distracted in your day-to-day life. The objective is to feel calmer, more connected with those around you and to be balanced and focused.

This is achieved by being reminded to be mindful throughout the day. Whenever a notification is received, this is the time to stop your thoughts and just be present.

The app could also be used to provide regular affirmations or reminders of what sort of person you would like to be.

A premium set of hacker culture stickers, Emoticons / Emojis and symbols.

There are 75 fantastic stickers, 45 are animated and 30 are static images. Includes a set of pixelated emoticons.

Be the master of texting with a sticker which captures exactly what you want to say. Game Over Man!

You can overlay these over text or photos. Just tap and hold, then drag to where you want the stamp placed. You can also rotate and resize each sticker.

A feature introduced with iOS 10 is the option to send messages with effects, like having the message inflate, appear in a shower of balloons, or be hidden by invisible ink. To access effects, type your message or insert a picture in the text box, then 3D Touch (or tap and hold on older models) the send button instead of just tapping it as usual.

If you haven’t used iMessage sticker packs then there are some traps for new players. To help people overcome these issues, we have written a couple of articles which may assist:

1. I’ve installed my sticker pack but can’t find it! (https://www.reefwing.com.au/?p=356)
2. I bought an iMessage Sticker pack on iTunes and can’t find it on my phone!! (https://www.reefwing.com.au/?p=323)
