Wearable Smart Sensing Insole

I created a wearable smart sensing insole to monitor and analyse information from your feet to help improve sporting performance and reduce injury all through a remote mobile app. Full details available at instructables where you can vote for me in the wearables contest. Thanks!

Pet Robot Ball

My pet dog loves playing with toys especially ones he can chase! I built a robotic ball that switches on and rolls away whenever he interacts with it, notifies me via my mobile phone where I can then take over control and finally powers down when the fun is over to save battery. Full details available here. If you like this project, please vote for it in the robotics contest at instructables. Thanks.

IoT Push Button (D1 Mini)

I made an IoT Push Button (Think of those Amazon Dash things) that you can use to control your central heating, turn on/off your lights and even request drink refills when relaxing in the garden (provided your other half is making the drinks of course!).

This project uses a D1 Mini micro-controller and should run for months on a single battery using the deep sleep feature.

You will need:

Wireless Power Monitor

RenderTitleBlynk2

Ever wanted to remotely monitor/log power usage of your electronic appliances? Well now you can with this DIY, 3D printable monitor.

As well as the 3D printable parts available from thingiverse, you will need the following:

Simply connect the parts as shown in the schematic below, solder the switch in place after assembly within the 3D printable housing.

Note: To allow use of the sleep mode you will also need to solder a connection between the RST and D0 pins of the D1 mini.

Power-Monitor-Schematic

Download and install the Blynk app, use the following QR code to get your own copy of the power monitor app.

 

Configure the Arduino sketch for your own WiFi SSID and password as well as your unique Blynk autherntication token.

The latest Arduino sketch can be found here. Further details can be found at instructables.

Blind Controller V2 Announced!

Blind-Controller-V2-Promo-Graphic

Exciting news, I will soon be releasing a new version of the Amazon Alexa compatible blind controller, similar in design but with all new hardware. Powered by a Wemos D1 Mini micro-controller, it is now WiFi enabled and can be operated from within a mobile app from anywhere in the world.  Upgraded motors allow for precise, repeatable positioning and easy calibration either from within the mobile app or using the full manual controls. The mobile app also allows scheduled opening and closing at pre-configured times.

Check out the teaser trailer below and be sure to check back soon and subscribe to my YouTube channel for future updates…

 

 

WiFi Enabled Soil Moisture Sensor

Combining the D1 Mini and Blynk to create a wireless Soil Moisture Sensor…

This small portable sensor can be used to alert you to the moisture condition of your plants. In the future it can be combined with a water pump to create a fully automatic garden system.

To begin you will need to download and 3D-print the 3 separate parts available via thingiverse.

You will need the following components:

WeMos D1 Mini
3.7V 14500 Li-ion Battery
Capacitive Soil Moisture Sensor
D1 Mini Battery Shield
WS2812 RGB LED
1 x AA Battery Holder

Connect everything together using the following schematic:

The shield can be connected directly to the D1 mini. The breadboard is used above for reference only and components should be soldered and crimped together in order to facilitate positioning inside the printed housing.

Remember to connect the RST pin to D0 in order to enable sleep mode.

The final assembled device should look similar to the image below:

Download the Blynk App to your smart phone/device and create a new project based on the following:

Screenshot_2018-12-16-22-42-33-140

Upload the sketch to the D1 Mini using the Arduino IDE. Edit the sketch to include reference to your WIFI SSD and password as well as your unique Blynk authentication token.

Insert and charge the battery and watch the data roll in…

Use the sliders in the app to adjust the threshold at which the dry/wet alerts are activated. The sketch can be further customised if your sensor needs it as well as for things like the length of time to sleep.
