This article focuses on how to use the existing USB code library and HID report descriptor info to implement joystick functionality. Human readable HID report descriptor and report information can be easily obtained using USBHID_desc.pde sketch – see previous article for details. This information will help you getting field details such as size and count info. Also, if you don’t have Arduino Mega or 2560 to run USBHID_desc , report descriptor for your device can be obtained using one of many PC tools known as USB analyzers, or even the official usb.org device verification tool .

The US based JOBS act could potentially inject more startup capital into the market . Now individual investors can invest up to $10,000 in a company in exchange for stock (up to $1 million). While the JOBS act could have potential abuse, Kickstarter has similar issues as well. A drones project was cancelled when the product to be delivered was in question. Rigol does call themselves test equipment and are now selling a 2000-series scope (or will be, eventually), a long awaited successor to their 1052E model.
This week we launched Shenzhen 2 U , our new online boutique that brings the savings of Shenzhen’s electronics market directly to you. We’ve stocked it with some great LED products that are factory direct and very hot. We have 4 different LED strip offerings.All of them are flexible, self-adhesive, and very bright due to their high LED density of up to 60 LED/m. They can be ordered in a waterproof format which is great for outdoors and/or wet applications.

Automatic cursors are supposed to show what and where stuff is measured on a waveform when automatic measurements are used. This is pretty useful, if it works as expected. Suffice to say that it doesn’t always do that – unfortunately. I’m probably not the first one to do it, but it is still a very good idea. Especially when combined with a product like ‘ Parted Magic ‘.
Get that Club Mate cold and those soldering irons hot because it’s time for another Interactive Show ! We’re putting out the call to hackers around the globe to come show your stuff at our annual party. This years theme: Physical meets digital . Think kinect-controlled robots, or video game elements brought into the real world, or crowd-sourced smartphone accelerometer collaborations.

Yes, the things you have heard are true. After four glorious years of freelancing and working on fun open source hardware projects , I am going full-time again. Yes, Jeri works there. No, she is not my boss (or anyone else’s, more on that later).

Having already torn the thing apart and discovered that the repair would include both the drum+spider assembly ( not available separately, which may actually make sense given high-speed spin balancing) and the front half of the plastic tub, I priced them at RepairClinic and Sears Parts Direct. In round numbers, this adventure would cost $300-400 just for the parts, a bit less than half the cost of the washer. As I recall, the Sears price for the drum was roughly twice that for RepairClinic, while the tub was about the same.

We spent the day yesterday in the pits with the teams participating in the 2012 Silicon Valley Regional FIRST Competition and brought back a whole heap of pictures . Thursday is fix, check and test day at the regional competitions. Each robot has been sealed up since the end of the build season and the teams bring them out and get them certified for competition and run them through practice matches. The pits were extremely busy for most of the day, getting the robots ready for their practice rounds and repairing them afterwards. Team Gatorbotics was one of several local all girls teams.

When I was growing up, canning was for old folks and cranks and separatists --oh, and for my parents, who spent every summer of my Virginia childhood scrambling to convert overflowing bushel baskets of fruits and vegetables from their garden into a pantry lined with shelf upon shelf of colorful canning jars, not to mention a stuffed-to-the-rim chest freezer or two. Not for me. I had better, far more important things to do. I can't remember what they were.HackHut

Absolutely epic maker tale from former Atari dev Scott Williamson, who writes: So, you may be wondering why anyone would bother to make a version of a 30 year old vector arcade game on an arcane 33 year old platform? I was inspired by one of the greatest and most influential game programmers of all time to make something that he said was impossible.
