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 →
A suitable tool to safely discharge capacitors is needed when you want to work with circuits that have dangerous voltages inside them. Typical examples of such devices mains powered switch mode power supplies (you need to safely discharge main capacitor) and different cameras (the flash unit has a large capacitor charged to 400-500V voltage). Those →
In my previous posting Current sensor for multi core cable is talked about measuring AC current flowing on cable where you don’t get access to individual wires. In that posting I mentioned that I saw Modern Device blog article Current Sensor that seem to be doing exactly that. This sensor is designed for providing an →
I bought some time ago Key Style Stainless Steel Hot Swapping USB 2.0 Flash Drive – Silver (8GB) hoping to get a nice USB memory that I can include to my keyring. The product got even some good reviews at Dealextreme product page. At first everything looked good. The good things was that this product →
