Back into 3D printing world

It was always a pain to use […]

Motors and Frame

Journey into robotics. The beginning of T.H.O.R. Rover

Robotics is fascinating and complex topic.  I’ve always wanted to dive into it headfirst, but seeming complexity, cost in both time and money has stopped me so far. Finally I decided to dedicate some time and explore this subject by building my own robot.

First look at Boss Laser LS-1630

New Laser machine arrived on Tuesday!!!  I’m jumping from joy as this is one serious pieces of equipment!  My 50W eBay laser looks like a tricycle comparing to this monster.  While it has same 60W tube (I’ve upgraded my eBay laser a while back), Boss Laser has much large cutting better and better overall build.  This is Generation 5 LS-1630, which from what I’m hearing was designed from ground up by Boss Laser company.  Comes with full one year US support too!

I decided not to call this video unboxing, but rather a first look, because I already un-crated it 🙂

Introducing new “brushed gold” hand spinner

My fidget hand spinners are a huge success, so I’ve been spending more and more time designing and refining them.

Newest addition is “European Brushed Gold” finish spinner.

Just like brushed aluminum and walnut spinners, it’s finish material only imitation, but a pretty convincing one! 🙂

Just don’t go and propose with it to your fiance 😉  Or […]
