Hi Jonathan, Awesome job and great idea with the UV lights they look great, I've ordered some to try out myself and some UV Reactive Green PLA samples for the plasma ball in the tube! Thanks for sharing your build and I'm glad you enjoyed it! Jack

The TM1637 is ac IC that handles the 4 digit 7 segment display connctions, so that TM1637 chip connects to the 8 pins on the display itself. The chip drives the LEDs in the display based on simple I2C commands it recieves from the Arduino.This means that the Arduino only need to use 2 pins Rx and Tx instead of the 8 pins that the LCD Display needs. Also now that we are just sending standard I2C signals it makes it much easier to programme everything.Using modules like this is always easier especially when using a small microcontroller like an Arduino Nano, as it has very limited I/O.

Hi, is it a 4 bit 7 segment display? you will need to follow another guide of how to configure it like this one to get there working https://create.arduino.cc/projecthub/SAnwandter1/programming-4-digit-7-segment-led-display-2d33f8The issue with doing this is that my code will not work, you would need to rewrite the display sections. I would advice either buying a cheap TM1637 IC and find a guide on setting that up or the better option would be to buy a TM1637 4 bit 7 segment display module like I used otherwise the wiring can get messy!

Hey, that is a possible solution I think although I don't know how bright this method would be. I'm quite interested in how the Funko Toy Ricks Portal Gun does it (seen here https://youtu.be/9eXw0bzWeRw?t=123). I think its just a High power LED behind a lens with the portal image on it which would be nice and simple. I'd be tempted to buy one to see how they did it if they were on sale.

Hi Sorry I did mention it briefly on 3D printed parts slide which in retrospect is probably the wrong place. You are correct it is a bubble sword like this one, I got it from a local shop for £1 https://www.ebay.co.uk/itm/Bubble-Wand-Sword-Child...

Nice one, I've very interesting in building one of these myself! Thanks

Hi Jamie, Actually that's a really good idea I did plan to do something like that initially but totally forgot about it. I might have a look at modelling something tonight and possibly try printing it in either Green or Natural PLA not sure what would work best

Can confirm that yes it does work if you are not Rick! Unfortunately the real portals only work for Rick :)

Just finished watching your Youtube video where you used this, once I've finished with my LoRa project I think this is next on the to-do list! :)

Hi can you give any more details on what the error is? Otherwise I'm not sure I can help. Regards Jack
