Must look closely at the Broadcom Wireless Internet connectivity for embedded devices –

Broadcom’s Wireless Internet Connectivity for Embedded Devices (WICED™) platform (pronounced “wik-id”) eases development effort and simplifies the implementation of Internet connectivity in an array of consumer devices, especially those without existing support for networking.

Developers use the WICED platform to create secure wireless networking applications on a wide array of platforms encompassing Broadcom wireless connectivity technologies. The WICED platform encompasses.

From Siggraph – balancing 3D printed objects

Balance is a delicate compromise between shape, weight and pose. To give a feel of dynamism, many 3D rendered objects stand in impossibly balanced configurations. As soon as you try and print these, the illusion meets gravity, very often sounding in a small thud. Whilst there are several other laser cut support options available as are stress evaluating and relief algorithms, this is a rather simple polygon based method offering to optimise print designs to make the objects balance.

IoT platforms

Note to self.

2 key IoT platforms to keep track of!

Smartthings. Offers forum support to build projects and a web based IDE. Uses SmartThings “ThingModule” (Zigbee Radio, Antenna, Signal Amplifier, and the SmartThings firmware that is ready for direct integration into manufacturer devices). SmartThings Cloud using IP connectivity (either Wifi or Cellular but bypassing any local hub integration) via SmartThings APIs and OAUTH2. Focused on home automation and offer 3 kits (althought I cannot find them on the site)* covering

Home security (lights, doors, garage doors), Home watch (environment sensing – temperature, control, etc) and Family life – pets, access, monitoring…

* Edit: they were available to supporters through their kickstarter campaign along with the SmartHub – Seems very similar specs to waspmote.

Project of interest – by Danny Kleinman – danny@smartthings.com – IR remote hack w ThingShield Arduino.

Xively – part of LogMeIn (IoT cloud). Company info: LogMeIn is headquartered in Boston’s Innovation District with offices in Australia, Hungary, India, Ireland, the Netherlands, and the UK.

Released jumpstart kit with ARM (John Cornish is quoted) – NXP LPC1768, ARM Cortex-M3 based mbed. Available via Cool Components, Priced £57.77

Specs: 96MHz, 32KB RAM, 512KB FLASH

I/O: Ethernet, USB Host/Device, 2xSPI, 2xI2C, 3xUART, CAN, 6xPWM, 6xADC, GPIO

Peripherals: see mbed Application Board

Power: 5V USB or 4.5-9V supply

Will have to compare the full specs to all of these boards side by side.

Build a bare bones Arduino clone which maximizes its use of real estate

Roll your own Arduino – YABBA

Hackaday

barebones-arduino-clone-at-home

Check out all the stuff crammed into a small swath of strip board. It’s got that characteristic look of a roll-your-own Arduino board, which is exactly what it is. [S. Erisman] shows you how to build your own copy of his YABBS; Yet Another Bare Bones Arduino (on Stripboard).

The strips of copper on the bottom of the substrate run perpendicular to the DIP chip and have been sliced in the middle. This greatly reduces the amount of jumpering that would have been necessary if using protoboard. A few wires make the necessary connections between the two tooled SIL headers that make up the chip socket. On the right hand side there a voltage regulator with smoothing caps. The left side hosts the obligatory pin 13 LED, and the crystal oscillator can be glimpsed on the far side of the ATmega328.

Pin headers along either side of the board have been…
