My 2016 Halloween project: Spiderweb
How was it done? Watch the video:
Was it a successful project? Well, not quite. The rope supposed to be “glow in the dark”. And it does glow. Immediately after being exposed to some strong light. But sun set way too slowly I tried blacklight and camera flash, but they do not produce enough power for the whole spiderweb to glow. I can make a little piece glowing, but that’s no fun. But I like how it turns pink in the flash light. And it looks cool enough even without glowing.
How do you erase ink from the paper? I made an educational video.
I have got a function generator and power supply for $30 total.
The generator works great, but power supply was kind of weird. It was only adjustable when I did it really, really slowly. Once I tried to go faster, it was jumping to 1 then back to 0 then to 1 then back to 0. Yes, it was usable in general, but for a impatient guy like me it was a torture.
So I took it apart. There was a rotary encoder that did not click. It was just rotating smoothly like a potentiometer. This is clearly not what rotary encoder supposed to do. I decided, that I will likely not be able to repair it because some tiny part is likely broken, so I should buy a new one on ebay. But I decided to check it out first, so I opened it. This is the top part.
My preferred stress relief technique is woodworking.
I can drive Adafruit PWM hat from C#!
I converted Adafruit python code (Adafruit_PWM_Servo_Driver.py) to C# and it works!
I got tired of flipping food I cook with chopsticks. I do not trust plastic spatulas and I do not want to use metal ones on my ceramic pan surface. I can probably buy a wooden spatula, but why not make my own?
Here it is:
No, I’m not going to buy an elephant!
No, this is NOT an elephant toilet!
How do you achieve the World Domination without a descent Doomsday Device?
Sadly (or maybe fortunately), there are no Doomsday Devices in stores
(even in ATF Bureau regulated ones)
That’s fine, I built one from scratch for Halloween.
Here is how it looks in real life:

How to fix a crossbow with a domino:
I’ve got a nice crossbow:
What is cool about it? It is really hard to beat. Computer is really smart! (Well, of course, it is very dumb. However, I know a trick or two to make it look smart)
Why did I make it? I’m teaching Xenia to program, and this is what we practice on.
