Below is a video of a 35-second solve in total darkness. No, not a blind solve. I can’t do that!?! A solve on an LED-backlit cube….
crystal cube hack – part 2
I wrote last week in Part 1 of this post about hacking, so to speak, a Ghosthand Crystal Cube. As detailed in that post, I wired past the motion sensor and on-board IC that caused the irritating and impractical blinking. That forced the cube into a constant-on state once I connected two leads that I had temporarily extended through the core for testing.
As described below, I solved that problem with a switch inside the core that could be reached with a paper clip. Here is a video of the final result, showing the cube powering on/off and a sample solve in the pitch dark. It’s not a speed-cube, and it is prone to pops and lock-ups, so I solved at a casual 55-second pace.

I thought it would be a fun novelty to have a cube that lit from its core. It would make it easier to cube in dim light — and, let’s face it, not being able to cube in dim light tops the serious first world problems list!?! And it would be fun. There are some decent glow-in-the-dark cubes (e.g., the C4U ones). But those have to be “charged” and need a very dark environment to glow. They also don’t help one bit with sticker colors.
It turns out that there is at least one model of light-up cubes: The Ghosthand Crystal Cube, which is a bargain at a mere $5.99. Knowing I’d want to “hack” the cube, I bought three.
Hack it? Yep, hack it. Continue reading
