In the past, I’ve shared a few longboards I’ve built on Instructables, but this time it’s a little bit different, because it’s ELECTRIC! In this I’ble, I will outline the tools, parts and steps I took to create this fast, long range electric longboard.
The 76477 Complex Sound Generation chip (1978) provided sound effects for Space Invaders1 and many other video games. It was also a popular hobbyist chip, easy to experiment with and available at Radio Shack.
This article will review two different structures to implement a high-throughput FIR (finite impulse response) filter: the pipelined direct form FIR and the transposed structure. We’ll see that generally the transposed structure is the preferred implementation for a FIR filter.
As [Glen] describes it, the only real goal in his decision to design his single-key USB keyboard was to see how small he could build a functional keyboard using a Cherry MX key switch, and every fraction of a millimeter counted.
Recently I saw a cool build by GeckoDiode and I immediately wanted to build it myself. The Instructable is Space Invaders Desktop Clock and I recommend you have a look at it after reading this.
There’s a few open source options out there for creating electrical schematics. KiCad and Fritzing are two that will take you from schematic capture to PCB layout. However, there’s been limited options for creating wiring diagrams.
Based on this algorithm, we’ll derive a block diagram for the circuit implementation of binary division. Finally, we’ll look at the ASMD (Algorithmic State Machine with a Data path) chart and the VHDL code of this binary divider. Consider dividing 11000101 by 1010.
E-waste is becoming an ever increasing problem in our disposable society. In order to promote the idea of a circular economy I have revived a broken laptop (2007 17″ Macbook Pro) by powering it off my smartphone.
The trend in video games is toward not being able to differentiate them from live-action theatrical releases, and games studios are getting hard to tell from movie studios. But quality graphics don’t always translate into quality gameplay, and a lot can be accomplished with minimalist graphics.
“These days, people tend to jump straight to rapid prototyping with a 3D printer. But, the reality is that it’s only rapid relative to traditional manufacturing.
