netmonlabels-1024x768

Zak Kemble builded a network monitor device able to show basic network statistics on a small LCD screen. He writes:

Whenever I want to see why a download is going a little slow or getting lag on an online game I’d have to log in to my routers web page or SSH in to see if its someone else in the house downloading/uploading, the net connection going wonky or just the server, this was a bit annoying to do, so I made this device to constantly show network statistics.

USB has established itself as the new standard for connectivity. That is why USB connectivity has become the “holy grail” of most embedded applications.

Well, let me get straight to the point. If you want to start developing projects with USB interface, you want to have the proper development tools. To have the tools that you need, you either have to buy or to do-it-yourself.

This page describes how you can use a small AVR device and a real-time clock (RTC) to build a hot-pluggable USB real-time clock (I’ve named it just usb-rtc), mainly for usage with ultra-low-cost hardware meant to be used with Linux.

The overall cost for one of those thingies I’m describing here is about 15€-20€, which isn’t really cheap. But I find it a valuable thingy because the result is a hot pluggable RTC, usable by almost any device which has USB. So it’s very likely you will use it for much longer than the device you currently want to build or search it for. In addition you might want to use it as a (hot pluggable) USB-I2C adapter too. The software I’m describing below already supports that.

The UBW board is a small board that contains a Microchip PIC USB-capable microcontroller, headers to bring out all of the PICs signal lines (to a breadboard for example), only costs about $15-$20 to build and is powered from the USB connection.

After the success of small modules USB – I / O converters – PUSBIO with MCP2200 circuit intended for development and small batch production, which we introduced in Article MCP2200 USB module and I / O , and recently introduced software for USB I / O modules , now the company introduces new modules Pandatron with relays and optocouplers.

Small Arduino compatible USB host board. Take control of your Android phone or other USB device in your next project.

This project began the day I saw the Google IO 2011 talk about the new Android Accessory Development Kit (ADK). I had never seen or used an Arduino before. I had written a few Android programs but something about being able to connect custom hardware to my phone inspired me to start this long trip down hardware lane. Specifically, I was inspired to create motorcycle navigation software knowing that I would be able to create a remote control for my phone that would allow me to control the software with gloved hands. I finished the navigation software a few months later, and it has been a great success. This board has allowed me to complete that project; I now have a remote control attached to my motorcycle.

The micro-sized, Arduino enabled, usb development board – cheap enough to leave in any project! Erik Kettenburg writes:

The Story: We set out to build a little brother to the wonderful Arduino line of development boards – we were tired of leaving our valuable Arduino’s behind in projects, or worse, ripping apart old projects to build new ones! We also felt the Arduino was too big and powerful for many projects where we only needed a few pins, or an SPI or I2C bus. And so the Digispark was born! To us, the best things about the Arduino is the community, the easy of use, and the IDE – by making the Digispark an Arduino compatible development board all of those remain common. Plug it in, power your project with USB or external sources, program it with the Arduino IDE, and easily use existing Arduino code! But with its small size and low cost you can feel free to leave it in your project, give one to a friend, and use them everywhere!

FT245RL IC testing software. You can set the output and get input status from your PC’s screen. It is thus possible to enable or disable the 8 channels, for a 8-channel input.

Debugging USB devices – [via]

This is just a friendly FYI to all hackers. Once you get a little more adventurous you can get real confused about what usb devices are plugged in etc (which com ports,…)

my best new friend is usbdeview from nirsoft http://www.nirsoft.net/utils/usb_devices_view.html

It shows you everything about the plugged in usb devices, updates on the fly, v good

The AVR Stick is a simple data logging device that instantiates itself as an HID keyboard and reports the voltages, along with a ‘timestamp,’ from two pins on an ATtiny85. The device uses open source firmware availabe from Objective Development (http://www.obdev.at/vusb/) called V-USB to implement the USB 1.1 standard. The code that runs the application was based on the EasyLogger example application from Objective development.
