Even a small figurine can play a big performance

obr1730_uvod

New aerial from 2J will surely not surprise you by its size, however features of the antenna are worth noticing.

2JW035 antenna measures only 52,5mm and is intended for WiFi and Bluetooth devices in 2.4 a 5GHz bands. The gain is 5dBi and the VSWR value is below 2.6:1. A big advantage of this antenna is a possibility of its versatile placing, as it contains a hinge.
So as to suit various customers´ requirements, the producer offers a possibility to order this antenna with three various connectors:

  • 2JW035-C20Nb is equipped with hexagonal black SMA connector
  • 2JW035-C675 is equipped with a round SMA connector
  • 2JW035-C442, which is also our standard stock type is equipped with a round black reverse-polarity SMA connector (RP).

For special applications, there´s also a possibility to order this antenna in a custom specified colour.

Detailed information can be found in the 2JW035 datasheet.

Pozyx shield gives position

20150604033001_PozyxShield

Resolving the position of free roaming robots can be quite challenging. You can only expect to get accuracy of around 6 to 10 meters by using a standard low-cost GPS system and that can be further downgraded by poor signal strength inside buildings. Bluetooth and WiFi positioning can achieve 1 to 5 metres resolution but that’s often not enough. The Pozyx system has been developed to achieve a positional accuracy of 10 cm and works indoors or outdoors.

Four ‘Anchor’ transceiver units attach to walls or fences surrounding the space in which the Pozyx Shield operates. Communication between the shield and the four anchors allows the shield to determine its position and orientation within its operational area.

Simple Ham Radio Bluetooth Interface

Ham radio is a popular hobby and service in which a licensed amateur radio operator explores communications equipment. Typical ham radios do not have bluetooth support, which may be hassle for some. None of the transceiver manufacturers are providing a wireless interface. However, with this ham radio bluetooth interface, communicating and listening to other entity would be easier. The device uses Bluetooth module and a circular connector. The TE’s CeeLok FAS-T connector is one of the most rugged, small, 10 GB Ethernet, field terminable I/O connector. It has been designed to perform in some of the most extreme environments in the industry, while providing substantial size and weight savings via its small shell size 8-form factor.

The design is simple that anyone can construct it without having a hard time. The device uses a Bluetooth module, a regulator, connector and few passive components. It automatically connects to the PC or any bluetooth supported device when the application is started. Wireless headset would be very useful for ham radio operators so they can freely do whatever they need to do without being stagnant. In addition, a single blue LED indicates power and pairing.

Licensed amateur radio operators communicate with each other in nearby places, across the country, around the world or even with astronauts in outer space. Hams use a variety of frequencies for communications and may operate from just above the AM broadcast band to the microwave region, in the gigahertz range. This device may be useful for other applications such as aerospace, in flight entertainment and connectivity, defense and marine environments.

This project starts a few weeks ago. My six years old daughter usually sleeps with a light on in her bedroom. Talking with her, we decide to hack her LAMPAN Ikea lamp to make some improvements, including a manual RGB controller to set the light colour, a timeout to turn off the light after 30 minutes without changes and a bluetooth connection to control the lamp with a smartphone or tablet. So, if you continue reading the post, you’ll see what we develop!

CypressEZ-BLEPRoC

by elektor.com:

Following on from the release of their PSoC 4 BLE chip at the Electronica Exhibition last year, Cypress Semiconductor Corp are extending their play in the Bluetooth market with the introduction of their new EZ-BLE module. The module contains the PSoC 4 BLE chip together with two crystals, an on-board chip antenna, RF shielding and passive components, all in a compact 10 mm x 10 mm x 1.8 mm form factor so that designers using the module can apply to add the Bluetooth logo on their products by referring to Cypress’s Qualification Design Identification (QDID) 67366, a unique serial number assigned by the Bluetooth SIG. The module is compliant with wireless regulatory standards in the U.S., Canada, Japan, Korea and Europe and offers a significant saving for designers in development, testing and certification costs.

TEXAS Instruments has announced the new SimpleLink ultra-low power wireless MCU platform. The platform has been designed to use so little energy it can be powered from harvested energy or will run for years on a coin cell. For versatility the platform supports multiple wireless connectivity standards using a single-chip and identical RF design. The SimpleLink ultra-low power platform supports Bluetooth low energy, ZigBee, 6LoWPAN, Sub-1 GHz, ZigBee RF4CE and proprietary modes up to 5 Mbps.

The first members of the SimpleLink devices to be introduced are the CC2640 which supports Bluetooth Smart and the CC2630 for 6LoWPAN and ZigBee. The CC2650 wireless MCU supports multiple 2.4 GHz technologies including Bluetooth Smart, 6LoWPAN, ZigBee and RF4CE. The support for such a wide range of radio standards helps future-proof designs and gives the ability to configure a chosen technology at the time of installation in the field. Planned for introduction later in 2015 are the CC1310 for Sub-1 GHz operation and the CC2620 for ZigBee RF4CE.
