Well, you can see the difference and I will tell you why!

Their frame, LED strips and the other electronics will cost a lot.

So, as I told you before, my goal to keep it cheap and simple as possible

If you would like to continue just follow those steps.

Led strips: I used the simple version, the un addressable analogue version instead of the neopixel for two reasons, cheaper and requires simple code

Faces: I tried to use glass as it is cheap but I could not find a way other than waterjet to cut and that will empty my pockets, so I used acrylic sheets and laser cut and minimized dimensions as possible

Fixation: Using simple light weight 3d-printed part and some stickers to hide corners

Base: Wood sheets was a reasonable solution as it easy to work with and easy for finishing

Electronics: designing a PCB with the just the parts I need and a communication module like Bluetooth and lowering power usage to just use a cheap adaptor

I will provide you with the full BOM later

for the faces, remember when I said minimizing dimensions?

I made 3 faces on a sheet and used 3mm acrylic, which ended by like 20cm height face

made two holes for fixation on each corner node and one hole for the corners on the base

that means we have two files to cut, cut 6 of the upper face, 5 of the lower face, and one for the base surface

Here are the DXFs

3d printing time

we have 20 nodes; 5 for base and 15 for the rest

Here are the STLs

you will need around 60 m3 screw + its nuts

for the full eagle PCB design feel free to visit our sprint review pages

and for the components go to the BOM file

At first, I have to confess that I am totally newbie at this mobile application things and I also found that I am too rookie at Coding

I tried to write my own code, hola, it not reliable and not user-friendly at all so I searched online for solutions and found many like the RoboRemo app and some apps on the google play store

starting with an app on google play which is called led control, tested on Arduino UNO and it worked fine with their code but when I tried to use it with attiny44 and uploaded it, it refused to change its state, the other ReboRemo still have the same issue, so I tried to use another app called Color LED Controller, that worked great but the app itself keeps mixing color faulty and ruins color

you have it all in this tutorial

Anyway if you have developed any app works for attiny44 or have a hint what the problem is, please send me

NOW, you have to put them all together,

• glue the foil on acrylic faces

• install faces together with their fixation using screws

• glue the led strips on corners and try to cover as many corners as possible( not with cutting and soldering them together as it will be too much waste of time)

• cover the corners outside with rectangular black stickers

• glue the base acrylic with the wood upper base

• connect the led strips wires to the PCB and put the dc jack connecting it with a cable to PCB

• install the app and pair your phone with the Bluetooth module and here we GO!
