Musical Instrument Amplifier Embeds a PC Inside



Orange Amps' new OPC, a combined PC and Amplifier is designed for Guitar, Keyboard, microphones and more. It includes WIFI and Guitar Effects software and will be available in June 2010. This could have a lot of uses for musicians, you could pair this with a USB MIDI controller for drums, keyboard, or wind instruments. It will be a nice compliment to USB programmable guitar effects. If successful, it will create more demand for PC connectivity in audio electronics.

Camera 2.0 Open-Source Digital Camera Project

As part of the Camera 2.0 project, researchers at Stanford have developed the Frankencamera shown here, "an open-source camera platform that runs Linux, is fully programmable (including its digital signal processor) and connected to the Internet, and accommodates SLR lenses and SLR-quality sensors. Our current prototype...is constructed from off-the-shelf parts, in some cases borrowed from dead cameras. It's also ugly - hence the name."

This open-source project is being developed to help researcher gain more control of camera processing. Another open-source camera project, the Canon Hack Development Kit, allows some control through a series of enhancements, but according to the Frankencamera FAQ: "you can't use them to reprogram the camera's pre-capture sequence (metering and focusing) or to replace its post-processing algorithms (demosaicing, denoising, sharpening, white balancing, tone mapping, etc). The Frankencamera fills this gap"

The brains of the Frankencamera include a TI OMAP3 processor, an Aptina MT9P031 image sensor and an Elphel 10338 sensor board.

If the popularity of the CHDK is any indication, the Frankencamera is sure to have a cult following.

Virtual USB Analyzer

The Virtual USB Analyzer is a useful tool created by Micah Dowty and Scott Perry hosted on sourceforge.net. It's free to use and listed as a fling in vmware LABS, a diverse collection of free tools created by VMware engineers.

You have to run the analyzer in Linux but you can take the traces with any guest OS running on recent versions of VMware products. At the moment the Windows version of VMware Player is not supported, but you can use VMware Workstation, Fusion or the Player that runs on Linux. You can also load captures taken from the Linux usbmon utility and the Ellisys USB Explorer 200 hardware analyzer.

I'm using this to see how Linux configures a keyboard to diagnose a problem with an embedded USB host. I think it will also be very useful when working on a new USB device that you need to test with multiple operating systems.

Fritzing

Fritzing is an unique project that allows hobbyists to design and produce electronic prototypes. Started as a University research project, it continues with the support of users with the purchase of the Fritzing starter kit. Included in the kit is an Arduino Deumilonove 328 microcontroller board. You can also download the design application without purchasing a kit.

NXP Microcontroller Design Challenge

The NPX LPC1100 Design Challenge just started and offers contestents a free NXP LPCXpresso development platform ($29 value), if your design is approved by the judges. If your design is not approved, you can still participate and win prizes by rating design entries and giving feedback. The LPCXpresso is unique in that it can be used as a stand alone JTAG debugger by cutting the traces between the LPC-Link and the Target portions of the board. The target section for the contest includes an LPC1114 (LPC1343 shown in the picture). The processor architecture is the new ARM Cortex-M0, designed to be small and energy efficient for battery-powered devices. The development environment is an Eclipse-based LPC IDE from Code Red Technologies, its free but limited to 128KB downloads. The prizes for the contest are given as Apple Gift Cards of up to $3000.

Analog Devices New BF50x DSP

The new 50x series Blackfin Processors offer 400MHz at $4.50, and come with a new analog-to-digital (ADC) control module (ACM), PWM units, optional on-chip flash and ADCs. This family is targeted mainly to industrial applications such as motor control, power inverters, uninterruptible power supplies, smart metering, and advanced sensing. They also are recommended for portable medical devices—with the lower cost and high performance, they may be attractive for consumer electronic devices as well. The BF506F EZ-KIT LITE development board is less expensive than other Blackfin EZ-Kits at $199, and includes a USB debug interface so you don't need to purchase a JTAG device. Embedded Linux is actively developed for the blackfin at http://blackfin.uclinux.org/ with toolchain development and a uCLinux port.
