Just wanted to post a quick update on the LED coaster.
Its self contained now, its compact, its USB rechargeable with an internal 2000mah LiPo battery, and it looks amazing!
I took it with me to the PAXAUS 2015 After party and it was a huge hit.
See video:
I got my 3D printer a few days ago(The Micro 3D Printer, last night I sat down for 15 minutes and threw a super basic design together in Google sketchup. (I already had it installed…)
There’s two compartments in the underside, one for the LED ring+digispark, one for the battery+charger.
Not sure how I’ll do the bottom yet. Probably a thin sheet of plastic glued on.
I’ll print it in either white or clear pla, and apply some kind of coating to the top for water resistance.
First print was too small because sketchup messed up my measurements, but here’s some photos anyway:
New one is printing as I type!
And on that note, here’s some photos of the printer.
Note: I do find it prints better without a raft….
Hello everyone!
Another update on the ESP8266!
Recently, an Arduino compatible IDE was released for the ESP and I’m super keen to try it out. I’ll download it later today and give it a go, ideally I want the adafruit neopixel library to work as then I can connect my coaster to the internet!
More on that in a minute.
Yesterday two things arrived in the post, my 16 neopixel ring, and my NodeMCU dev board.
Both very exciting!
Maybe I can combine the two? 😉
The dev board is because ive had difficulty flashing the ESP chips in the past so I was hoping to have better luck with a breakout board with inbuilt USB TTL and a flash button. I did! It flashed the latest NodeMCU firmware right away!
Node MCU is an alternate firmware for the ESP that has a runtime for Lua 5.1.4 inbuilt! So this is the excuse I’ve needed to learn a bit of lua!
I’ll also be using this later with the Arduino IDE and I’ll make up an image for cross referencing pins.
The neopixel ring is to be used in my ongoing quest for the most amazing coaster ever.
It will make my drink disco!
I’ve had a prototype in the past using a single RGB LED, then another using a disc of them, and this one is a ring, but they’re addressable!
What I’m hoping to get is a sort of rainbow flowing effect happening.
Ive got the code at a good starting point, for effect testing.
All I did was modify the example sketch that goes through a bunch of possible modes 😀
I’m driving it from a digispark board, and in the final build it will use a 3.7v lipo for power.
The LED ring does seem extremely bright, and gets a little hot during normal operation so I better look at dimming the LEDs as I only need enough light to light up my drink! Not the room Hahaha
There’s a few different sized ones too. The one with 16 and the one with 60 LEDs cost the same! D: sadly I don’t need that many though it’s far too big for my purpose hahaa
Maybe I can find a use for 60… Hehehhhh..
Oh and they come in strips too and individual of course! And boards… THERES LOTS OF CHOICES OK?
Anyway,
That’s all for now, I’ll keep y’all posted!
Bonus: it sticks to the wall of the train lol
I made a batch script at work today to automate a few things as I was working on 15 PCs at once…
Thoguht I would share it here in case someone who happens to be in the same situation stumbles on it!
It has a number of features for example changing the PC name, changing the key for MS Office and then activating it, activating the local admin account and setting a password, auto logging a user in, and REBOOT =D
Its probably buggy, but worked 13 times out of 15 for me! so deal with it..
oh, install office doesnt work but meh. 😀

Update: This project died when I got a job and can afford off the shelf automation stuff :’)
It might come back when I start adding stuff like blinds and air conditioning control!
This project is basically me wanting to be able to automate my house but not wanting to fork over heaps of money for pre made systems.
I’m a bit lazy with details so if there’s any questions you have please comment below!
Newer Update v2.5
Ok, so it just occured to me that I could have bent the antenna down flat so that I wouldn’t have had to make any holes….
I got around to making a few changes, I’ll let the images do the talking for me:
A few notable things, white LED on ParaShield (I’m calling it that now) has been replaced with a less bright red one. Transmitter repositioned and wired a little nicer, Ethernet hole cut (Stanley knife, metal cutters and pliers).
Proper helical antenna added to both units, Rx unit now has single channel relay.
Also, I shoved it all in a box and added a 12v fan running off 5v from the ParaShield (may add fan controls/monitoring later) so nothing goes wrong with summertime here.
I’m just waiting for the other 433mhz things to add a manual light switch, and the infrared control unit. Codes all ready but need the RF receiver D:
.
Also, on the app side of things,
I added an all on/off section so when this projects complete, I’ll be able to stand out the front of my house, say something awesome, hit a button, and the whole house lights up or goes dark 😀 XD
New update V2
So I discovered this thing:
http://www.ebay.com.au/itm/291262467339
I remember reading about this a while ago but didn’t care for arduino or anything much then.
But now I’m looking at this and seeing
This+Relay+PSU = self contained without need for base controller!
Plus, did I mention ITS FOUR FREAKING DOLLARS
how could I NOT order two!
When they arrive I’ll have a play around see if I can figure out how to control them 🙂
Will post here when I do!
In other news: I ordered proper 433mhz antennas for the things, and found the PS move squigy ball.
Will get a box soon for it all haha,
I’m also preparing some LED strip on the front veranda to be controlled by my UI. And I’m developing an android app (will design a tablet version later)
Using Tasker app factory!
Early screenshot attached!

Newer update:
I found chunks of a broken PlayStation move controller, for now I’ve soldered some resistor legs to the rgb led breakout board, and have the rgb led on the base station for reasons,
Hopefully further down the track I’ll be able to turn on a mood light fading through, (although once it starts fading how do I stop it…?)
Or even notifications for things!
It also acts as a status light,
On sending an on command it flashes green twice, the off command has two red flashes.
An unused but implemented command gives three orange flashes.
I need to figure out how to flash an error if an unrecognized command is received…
Also I hope to find the sphere from the PS move. And to mount the led on the proto shield, maybe move the rf transmitter to make a cut out for the Ethernet jack,
And then try my luck at designing a special case for it all.
Either adapting an etherten case, or making a shitty one from scratch.

————————————————————-
New update: I got it working again 🙂
Not sure what was wrong but I rewrote the code and now it works hahaha
Its a bit slow probably because of the speed I have the radios set to, but oh well doesn’t matter.
I soldered everything together into a little clump, minimising wires, and made a shield for the transmitter so it sits neatly atop the etherten.
I’ll be able to add other things to the proto shield later 🙂
Also. Found a leostick under my bed but I’m having issues uploading code to it. Going to use it to make that light switch if I get it working 😀
LOOK AT ME I BROKE IT SOMEHOW
Went for a trip to jaycar and bought some supplies, and a smaller soldering iron
When I got home I took down the roof unit, attached shorter cables so it would fit in the little box, and put it back together,
But just my luck, it’s not working now!
I send commands but it doesn’t trigger the relay….
I’ll have to connect it and look at serial monitor to see if it’s getting the command
I’ll also add some code and an LED that blinks when it gets a command….
Oh, and maybe the code to light that emergency light if a pin goes low?
I should probably remove all the pin headers and solder right to the board actually…
Or to a proto shield….
The current state of the project consists of an arduino pro mini clone, that listens on the 433mhz band for a command, and turns on a relay depending on the command.
There is a Freetronics Etherten acting as base station, connected to my LAN, and a 433mhz transmitter, this responds to http requests by sending various commands to the ceiling unit.
Its easy to add additional remote units and set up controls for them, which I plan on doing when I get blinds for my windows.
I also have a raspberry pi running Rasbian that listens for a button press, which is wired to our 20 year old retro doorbell, when the button is pushed the Pi sends a pushover notification to my phone/pebble, as well as plays a doorbell sound throughout the house directly connected speakers.
I’m also going to be setting up Asterix or something on this to add Cisco VoIP phones around the house.
I have plans for an analog control panel too, that has physical buttons connected to an arduino, to send commands to the various other arduino around the house.
For example, a light control panel, push one button to send off commands to all lights in the house, or indivuaul etc.
I also will be adding a sensor to the mailbox, probably solar powered, that sends a command in to the house when mail goes in, either emailing me, maybe a photo?
Sending my pebble/phone a notification, or just lighting up an LED on the control panel to indicate new mail!
