Nye brugere af Bluetooth til deres applikationer bør starte ved Bluetooth Low Energy, som er en del af Bluetooth version 4.0. Denne udvidelse af standarden giver store forbedringer til langtidsdrift på batterier. Det har dog en pris – kompatibilitet – Bluetooth er ikke bare Bluetooth længere. Understøttelse af 4.0 kræver både ny hardware og software.

Vejen fra Energy Harvesting til kunstværker
man dec 17, 2012
Historien starter på en Weblog omkring en lille højttaler ved navn “Skube”. 
Det viser sig, at bloggen har et dansk tilsnit, der henviser til Copenhagen Institue of Interaction Design. Deres hjemmeside gemmer mange sjove og skæve projekter, der har til formål at danne bro mellem teknologi og design – Den historie er vist set før, men ikke desto mindre var deres indgangsvinkel så tilpas anderledes, at jeg kom lidt omkring på hjemmesiden.
Forsiden byder blandt andet på åbne seminarer, om diverse emner lige fra marketing til det mere teknisk betonede. Under det teknisk betonede var der et seminar omkring Energy Harvesting, hvorfor jeg en sen tirsdag aften møder op i en baggård i Toldbodgade. Seminaret var med en efterfølgende workshop, hvor man med simple demoboards kunne bygge sin egen energihøster.

Altium for SI – Any Good? Part III
man nov 07, 2011
As part of a series of real life simulations on a very simple part of a circuit I try to figure out just how useful Altium’s built-in signal integrity tool really is. The price is right, but is it up to the job?
Altium for SI – Any Good? Part II
ons nov 02, 2011
In part I of this series of comparisons I started my quest to figure out if Altium is any good for SI analysis. It’s clearly one of the cheapest tools out there that allows you to do IBIS model based simulations. Forgetting the price, can it get the job done?
Altium for SI – Any good?
lør okt 29, 2011
Is Altium any good for signal integrity simulations? A question I get asked a lot. The price is right – you basically get the SI simulator for free as part of the schematic/layout/mechanical etc. package.
Quick FPGA Timing Analysis Check – now for Xilinx

We did a quick video introduction on how to check your timing constraints in Altera.
Quick FPGA Timing Analysis Check
tors jul 14, 2011
To achieve a good quality of a FPGA design – you need a good architecture, good RTL, pin-out files, and a flow and tool than can handle synthesis, place and route, bit file generation etc. One part of the design that in many cases is considered less important is timing constraining and timing analysis.

How do you do validate bypass capacitor selection and effectiveness on the mounted PC board?
ZigBee, WiFi and Bluetooth
ons maj 11, 2011
The drive towards wireless devices and replacing cables with wireless connection has definitely increased the number of short range RF solutions being developed. It’s been the talk for a long time, but based on our experience from the designs we are involved in, this is very much the case now. (mere…)
