Unicron Sound/Light Details and Kit Options

Posted by Chris Carpenter on

A number of people contacted me expressing interest in a kit of the sound/speech mod I did for my Haslab Unicron. I'm open to the idea but I wanted to first explain the details of how the mod is installed.  I posted a video to make it clear:   I think the most important thing to understand is that installation of the electronics requires you install the upgrade kit to split robot/planet modes.  It's not super hard but I know a lot of people are sensitive about mods to their purchases. That being said if there is still interest, I...

Haslab Unicron Light and Sound Installation Complete

Haslab Unicron Light and Sound Installation Complete

Got the sound and light installation for my Haslab Unicron complete.  You can read the first blog post here. The final install keeps most of the electronics inside Unicron with only the power bank and a USB cable exposed in the rear.  The final setup has a seven segment WS2812B led strip, Circuit Playground Bluefruit (CPB), DFPlayer Mini, a 3" speaker and a compact power bank for the power.  The code relies on the existing Adafruit Bluetooth Lowe Engergy (BLE) libraries for Bluetooth control. This lets me control the sounds and lights from my iPhone or an Apple Watch.  I'm...

The Chaos Bringer Unicron Speaks

"A ginormous weird lookin' planet just showed up in the suburbs of Cybertron." I got my Haslab Unicron and it is awesome!!! But it doesn't speak.  I really love Orson Wells voice as Unicron, even if he didn't.  So, I'm going to make my Unicron speak.   Below is a test run of a setup I'm working on.  I'm planning to separate the planet ball from Unicron and inside mount the electronics.  The goal is to use addressable WS2812B LED to light Unicron's maw.  I will also have a DFPlayer MP3 player connected to a Adafruit Circuit Playground Bluefruit to play...

Millennium Falcon Electronics Update

Millennium Falcon Electronics Update

My original plan was to put to lights and sounds in the Lego Falcon. However, I got sidetracked.  I started working on the 29" Hasbro Rebels Falcon conversion.  I finished up the CircuitPython code and it works well.  The electronics will go in the Hasbro Falcon first but a similar setup will also go in the Lego Falcon. The completed code currently has engine lights only because there really isn't a good place on the Hasbro Falcon to put gun lights.  The script has engine start, guns firing, hyperdrive, flyby and hyperdrive failure sounds.  I saw one of the commercial...

Han Solo's DL-44 Proffieboard Blaster Build

I just finished up building a DL-44 blaster with a Proffieboard. I'm not even sure how this project got started, which is a weird thing to say.  I love Star Wars and I'm a huge Han Solo fan.  If you have never researched the DL-44 props history do it.  Even if you have no intention to build one its, fascinating and hilarious to follow the history of the prop.  It's based on a C96 Mauser but it changes from movie to movie.  My build is NOT screen accurate and is somewhere between a A New Hope hero and Star Wars...
