Making a New Knife Handle

A few months ago my knife melted. Well, the handle did at least. 

I managed to get the blade out of the plasticy mess, but it’s hard to use a knife without a handle. 

I figured I’d make a new one, but it looked hard- it was the flip-in blade type of knife, so there wasn’t much 

of the blade to attach a new handle to. There was a hole in the end of the blade, which could be used to 

attach a new handle, but it had a bolt in it. So I got a new knife.

I recently found that lonely blade, and I realized I could just cut off the bolt thing (I’m not sure why I didn’t 

do this before). So I did, and then I made a new handle for it.

Steps to Making a Knife Handle:

1. Get all the extra stuff off the blade (ie. the bolt that used to hold it to the original handle
2. Find to thin pieces of wood to use for the main structure of the handle
3. Drill a hole in the end for the bolt holding in the blade
4. Attach the long metal piece on the back to also hold the blade
5. Measure and then cut the wood to roughly the right shape and size
6. Screw all the bits and pieces together
7. Add more thin wood in the middle and then glue
8. Sand

Here are some pictures of the process: (I didn’t get pictures of the first steps)

Electrolysis Experiment

Electrolysis Experiment!

I did an experiment for science class about making hydrogen using electrolysis.
Here are some photos and a video of the results!

See the full experiment here.

Hexagonal microcircuitry

Most conventional circuit chips are made with a square grid, but maybe it would be a better idea to use a hexagonal grid, which has more vertexes per area. This might make them more space efficient, but it might also not.

Just saying.

Wait, there could be one use-like thing...

If you connected a gray scale camera to a programmable transistor surface you could use it to make connections within the computer using photos to program the PTS. I don't know how this could be useful, but it's an interesting way to directly program computers with pictures.

Self programming transistor surfaces

OK here it is: (I don't actually expect anyone to understand it, since I was just writing down everything I'm thinking, I just put it on this blog for me to remember and other people to see what I was doing)

I was thinking about variably conductive programmable surfaces. Basically it would be a surface which changes its conductivity based on what electricity is going in to the parts of it. people could make circuits that program themselves based on inputs, and then program themselves differently when the inputs are processed, then reprogram themselves again, as many times as necessary. I don't actually know how useful it would be, or how it could reprogram itself, since to program itself it would have to have more outputs then inputs, and since it's a plane with a 1D outside with outputs and a 2D inside with the outputs, this seems impossible, unless the inputs and outputs are switched somehow,  but I don't know how that would work. It may be a good way to process pictures, or somehow draw physical circuits.

There is a way! I realized how the output could connect to the inputs- they could use binary pulses which a conventional chip could recognize and translate the pulses into direct non binary signals which could be used as the input to program the chip and make a new program.

Minecraft wizard house

 I made a magic-themed wizard family house in Minecraft. Fortunately, I took some screen shots of it. Here they are, along with some history.

The house and land of a powerful wizard and his family.

The wizard's hovering workshop

The wizard made all the buildings by magic.

Regrettably, the wizard didn't have magical measuring tapes, so the building are rather wonky.

The wizard often retreats to his hovering workshop. No one really understands what he does in it, but observers often experience large bangs and explosions.

Omni/multiderectional reflectors

https://en.wikipedia.org/wiki/Cat's_eye_(road)

Cat's eye reflectors are used on roads and places where light needs to be reflected directly back where it came from.

These only reflect light back in a
 very limited amout of derections.
I looked it up, and I didn't find any reflectors that reflect back in all directions, but I did design one myself. Here it is:

Grey=Mirror Light blue=Glass Blue=Light

As the light enters the glass it gets diffracted. This points it directly at the mirror, which reflects it back out the glass, which diffracts it again, and the light goes back to where it came from. If you where to look in this mirror ball, it would probably look black, because it would be reflecting your eye.
