How could I measure the normal power consumption of my USB gadgets? How can I measure how much current a smart phone charging takes from USB port? A special built USB measurement adapter for multimeter or USB current/voltage meter can answer to to those questions (and sometimes you get some information from device manager USB →
Modern smartphones consume so much energy that charging them once a day is not always enough. When they are used intensively, the user sometimes has to look for a power source in the middle of the day, and charge their device whenever and wherever possible. At first glance, it seems absurd to worry about safety →
Powering all kind of gadgets from USB power has become very popular nowadays. Soldering from USB power? Now there are products for this. The question is that how useful they are because of the limited power available from USB port (just few watts). The maximum power you can get from normal USB 2.0 port is →
Playing with an oscilloscope you’ll (probably) never own article tells that Hackaday staff were really jealous when [Shahriar] a video he made, in which he casually explains how a $500,000 160GS/s 62GHz oscilloscope works and then starts playing with it. Looked interesting do I thought to link it to my blog as well. Experiments and →
How to hack to an embedded device? On-chip debug (OCD) interfaces can provide chip-level control of a target device and are a primary vector used by engineers, researchers, and hackers to extract program code or data, modify memory contents, or affect device operation on-the-fly. Depending on the complexity of the target device, manually locating available →
I needed one more Arduino board, so I planned to check out this cheap (US$14.30) Duemilanove 2009 Atmega 328P SCM Board with USB Cable board. This is a clone of the Arduino Duemilanove with several enhancements not available in the original Arduino. The most important that is on board 2.54 grid male pin headers an →
I ordered some time ago Arduino Sensor Shield v4.0 because it is an easy way to connect input and output devices to Arduino. Arduino Sensor Shield provides three pin (ground, voltage, signal) interface for connecting all kinds of sensors (potentiometer, button, LDR etc.) and output devices (relay cards, servos etc..) to Arduino. The Arduino Sensor →
I some time ago wrote about phatIO file system based USB I/O and this is a continuation to this article. On weekend I successfully tested phatIO Dropbox Integration. The idea is the files on phatIO can be exported to dropbox allowing a cheap way of exporting the phatIO functionality to other computers or other devices →
News on the the Raspberry Pi camera module (5MP sensor at $25) has been around since earlier this year. Raspberry Pi camera module goes on sale article tells that THE CAMERA MODULE for the Raspberry Pi pocket computer is now available for order through RS Components and Premier Farnell/Element14. Documentation on how to set up →
When a hard drive fails, there are many times that I’ve wanted to clone the data from the hard drive to a new drive to recover. I just recently had the situation on my home PC that the hard disk was starting to fail. It showed things like slowing down very much every now and →
