Fresh hacks every day
This is a microscopic photograph of an 8085 processor die. [Ken Shirriff] uses the image in his explanation of how the ALU works. It is only capable of five basic operations: ADD, OR, XOR, AND, and SHIFT-RIGHT. [Ken] mentions that the lack of SHIFT-LEFT is made up for by adding the number to itself which has the effect of … Read the rest
[Wardy] built himself a high quality entropy source with parts he had lying around. It’s based on the hourglass entropy project we saw in a links post earlier this month. Just like that project, he is bouncing a laser off of the falling sand and reading the result. But he brings a few innovations to the party, and has test … Read the rest

At the center of this breadboarded circuit lies the green AD9850 … Read the rest
Everything you need to build a vacuum tweezers is laid out in this image. The parts should run you about $20 and when you’re done you’ll have the perfect tool for placing very small surface mount parts for reflow soldering.
This project uses the same concept as other fish pump tweezers projects but builds upon them with some interesting additions. … Read the rest

The inspiration for the project came after seeing a real stained glass panel featuring Iron Man which was available on Etsy for $4500.

There’s a new version of this really cool board out now that includes a few much-needed features like USB-OTG and a lower component cost that is passed on in savings to you.
A few months ago, … Read the rest
