Yesterday I did some testing with ProcessingJS. Processing.js is the sister project designed for the web of the popular Processing visual programming language (open source programming language based on Java). Processing.js makes your data visualizations, digital art, interactive animations, educational graphs, video games, etc. work using web standards and without any plug-ins. You write code →
This is few years old, but still funny: JAVA 4-EVER – Official Trailer A young man discovers a new world unfolding… Is it a real movie? No but the trailer is cool hehe This hillarious, except for the minor detail that also java sucks. The less you know about Java the more you laugh. →
ModPlayerJS is a player that runs in your browser for .MOD music files (the mainstay of Amiga and PC sample-based music circa 1990). This worked for me in Chrome browser but failed to work on Firefox. A good example of MOD music and what the player can do is to play 1DASBOOT.MOD with it (compare →
Every electrical engineer who does DIY projects knows that dozens of free resistor calculators are out there that can save quite a bit of tedious work. Other simple tools can be found, but traditionally the free tool arsenal would stop there. To help sort out the nonsense from the useful online tools, check this blog →
I mentioned Fritzing two years ago and now I find coming back to use this software. Fritzing is an open source software initiative that was to support designers and artists ready to move from physical prototyping to actual product. Today Fritzing is an open-source hardware initiative that makes electronics accessible as a creative material for →
I found a very cheap Arduino Nano board from Bang good web shop. I consider 5.34 Euros very cheap price for Arduino Nano, usually those cost $10 or even considerably more. Gravitech lists on it’s web page price to be $34.99. I wonder how this board can get this be built and delivered from other →
When I was designing the measurement circuit used in my How to measure smartphone power usage posting, I needed to design a RC low pass filter to it. I could have picked an electronics book and formulas in it, but instead of manual calculation I used Google to find a tool for that on-line. There →
A programming language familiar to all, BASIC, has turns 50 years old. This month, BASIC celebrates an anniversary reached by very few languages: 50 years of continuous use. Basic Turns 50 article looks back on 50 years of attracting (and repelling) new programmers. It’s difficult to imagine the computing world in 1964. There were no →
The problem: I need to measure how much power different Android applications make the phone to consume. Measurement method: Measure how much current the phone takes from it’s own battery. So I needed to somehow attack a measurement device between battery terminal and battery contact on the phone. This could be made by using a →
How about making your own smarphone? Making a cell phone or smart phone is not out of reach for clever hardware hacker. If you are planning to make a simple cell phone, ArduinoPhone project shows how you can build one. Or you can check the platforms used to build the cheapest cell phones. Are you looking →
