RasPiO Night Light - gently lights your way in the dark
See where to go at night without fully waking up. Only on as needed. Customisable RGB LED lighting. Ideal: hall, landing, garage, shed.
This project will only be funded if it reaches its goal by Tue, August 28 2018 8:00 PM UTC +00:00.
RasPiO Night Light is motion-activated RGB light that lights your way in the dark. It's a lovely build-it-yourself kit designed to be gorgeous to look at and fun to build, use and tweak.
- enjoy making it
- enjoy tweaking it to your requirements
- enjoy being greeted by it when you walk past in the dark
It's great for providing a bit of automatic nocturnal illumination in places like your...
What's in the Kit?
- a beautiful PCB
- a laser cut, Polar White frosted acrylic case with 4-way mounting holes
- an Arduino nano clone
- a PIR motion sensor
- all the through-hole components (surface-mount components pre-soldered for you)
- nylon nuts, bolts and standoffs
- USB to mini-USB cable
It's fully programmable so you can customise it to your own requirements by tweaking the Arduino sketch provided. You could also add any additional sensors or components you want, as all the Arduino ports are broken out to a second set of through-holes (labelled on underside of PCB).
Custom Engrave - Lovely Gift Idea
Add a custom engraving of your choice (optional extra) to the front to make it extra special. This would make a wonderful gift for someone special.
(Maximum engraving area 30mm height x 42mm width. Your text or graphic must 'work' in monochrome.) If you like this idea, a couple of the rewards include custom engraving.
Stretch Goal #1
If we hit and maintain a funding level of £10,000 the case will have two additional diffusing strips covering the long sides.
What Else do I Need?
To assemble the kit you'll need a soldering iron, solder and snippers. You'll also need a 5V power source, which can either be attached to the mini-USB on the arduino nano clone or 5V/GND on the PCB.
You'll also need a computer if you want to be able to flash the software to the Arduino nano clone. (We can do this for you as a 'power-up' but it costs a little extra.)
There will be a "RasPi.TV-style" assembly video and full step-by-step instructions as for other RasPiO KickStarter projects.
Very Hackable - Make it Your Own
Here are just a few ways in which you can hack the RasPiO Night Light to "make it your own".
- add sensors and other components - all arduino ports are broken out to additional through-holes
- tweak the colour(s) to your own requirements. Full 8-bit control of RGB (0-255) means you can generate pretty much any colour you want
- tweak the 'global' brightness (0-255)
- add a temperature sensor and use the LEDs to display the temperature when a person walks past (could do this during daylight when no lighting is needed)
- add a smoke or gas sensor and sound an alert with the buzzer (although please don't bet your life on it - this should not be in place of a certified smoke detector - but would be ideal for a supplementary one e.g. in your garage or workshop)
- add extra strips of APA102/SK9822 LEDs. (Connect to Co/Do/5V/GND on the PCB - as many as your PSU can cope with)
- add fancy LED animations
- customise fade-in/fade-out
- use it as a burglar alarm (parent/sibling detector) for your shed or bedroom
The potential for fun projects is limited only by your imagination.
The case back-plate has 4-way mounting holes which enable mounting in virtually any orientation.
You will need a 5V (0.5A or greater) supply - either mini-USB or you can connect wires directly to any 5V and GND on the PCB.
The basic Arduino sketch can be found here on GitHub. It uses the fastled library, set up for APA102 LEDs.
The LEDs on RasPiO Night Light will be APA102 or compatibles and will work perfectly with additional RasPiO InsPiRing, Adafruit DotStar, Pimoroni MOTE, APA102, SK9822 etc.
An Arduino nano clone was chosen because WiFi was found to interfere with the PIR, causing false positives. This was tried with both Wemos D1 mini and Pi Zero W with the same outcome - erratic PIR performance and instability which disappears when WiFi is disabled. So I took WiFi completely out of the equation. (Hard design choices :( )

During the campaign, I may add more power-ups, but for now...
- If you want your Arduino nano clone pre-flashed with the basic sketch, add £3 to your pledge and let me know using the KickStarter messaging system.

The early-bird rewards aim to ship in the second half of October 2018. The rest should be shipped by the end of November 2018, depending on how well the project does.

Risks and challenges
Through 6 months of testing and 3 types of board design trialled (on 3 different platforms) the electronics design is finalised. It works. There won't be any major changes.
Delays are always possible on any project - particularly if it does really well. Having delivered the last 6 consecutive KS projects early, I've learnt to try and build slippages into the schedule from the start. (Then if things DON'T go wrong, people get their rewards early.) I have a fairly good idea of what to expect, using known trusted suppliers, and have produced similar PCB projects before.Learn about accountability on Kickstarter
