Hey, I designed my Tensegrity too!
Why? To test my new 3D printer!
Here it is:

Large spoon
I had stressful last few weeks at work – things were not working as expected and blocking other people, and I was trying to solve it. Blocking other people stresses me out a lot. In the end I figured thing out and order is restored. But stress was still there? What is the best cure for the stress? Meditation and woodworking.
What do you you if you have a bigger stress? Well, you just carve a larger spoon.

Workbench Tray
I had impulsive buying on a garage sale some 10 years ago – two high quality cabinet slides.
And I always had a mess on my workbench. I have got an idea – make a tools tray and attach it to my workbench.
And here it is:

Looking for anomalies
When you run some process, there are two ways to look for anomalies – “white box” and “black box”. First one uses some knowledge about the process. Perhaps, you are already doing that. But comprehensive white box analysis is very expensive, so it is easy to overlook something. How about doing black box analysis on top of it?
I wrote some software that does black box search for anomalies in a series of images. It does Fourier transform, crops the low frequency part, calculates average, and then calculates distance from the average for each image.
Here is the focus sweep for the bug:

Microscope Z axis stage
Last time I promised to tell where did I get those 65 microscopic images with focus sweep.
Well, here is the microscope and Z stage:

Hyper Depth Of Focus
I have 65 images with extremely shallow depth of focus.
I wrote a software that finds sharp areas and combines them into a single sharp image.

TV Antenna
Is it hard to make a TV antenna?
You need a coaxial cable (to connect it to TV), a foam board and a piece of wire.
Schematics is very simple – you make a ring out of the wire, squish it and attach coaxial outer wire to one side and the central wire to the other side.
Plug it to TV and enjoy.
