Most user application need some sort of display and user interaction through buttons and a touchpanel.

Many possibilities, varying on the requirements:

Something we all use during the day: remote controls are everywhere: media devices, domotics and security appliances.

So far, we have built up some considerable amount of experience using low power setups in IR and RF approaches.

The RaspBerry Pi is really an excellent opportunity to experiment with all kinds of hardware, controlled by a Linux operating system.

We plan to dig deeper into this and see what practical uses there are for business applications.

High quality audio streaming is required in applications involving stage performance, HiFi in-house audio systems and the like.

Wouldn't it be nice to have a wireless system which supports webradio (think about all the online streaming channels.)

Looking for some output power, high sound quality and maximum efficiency? D-Class is the answer.

Along with a high quality volume control chip, this makes a great amp.

The Microchip dsPIC33F series has become our standard workhorse for circuits requiring both speed and processing power.

Mp3 decoding ranges from using VLSI chip VS1053 and the latest VS1063 along with a FAT32 filesystem on a micro SDHC card, up to the use of a dedicated USB-host chip like the Rohm BU9458.

A good quality FM tuner chip is hard to find nowadays!

Previous used chips for portable applications include TDA7021, TEA5768, Si4731. These are not well for suited high-end solutions.

Q & A:

Q: Where's the previous webshop? A: As of Jan. 2016, the previous webshop has been closed. We are now focusing our efforts to business customers only.

Q: Are the DIY KITs and circuits still there? A: Yes, have a look here. However, you can no longer order these (older, often obsolete) kits directly. Please inform via email for more details.

The FAQ section will gradually be building up in the near future.

Electronics Design:

• Schematic and firmware development.
