FRONT END PRE-AMP

FOR PC SOUND CARDS KA-1811 $18.95 plus postage and packing

Turn your computer into an oscilloscope, audio monitor or spectrum analyser! Plug the kit into your computer's soundcard and measure or monitor just about any audio signal. Most PC sound card inputs have a limited dynamic range, relatively low input impedance and poor overload protection - this kit will eliminate these limitations and allow tiny signals, like those from op-amps, to be measured without degradation. Kit includes case, silk-screened front panel, PCB, & all electronic components.

• Optional CRO probe to suit our QC-1902

• Or use it for amplifying a high quality microphone for sampling

AVR ISP SERIAL PROGRAMMER KIT

KC-5340 $28.50 plus postage & packing Program, erase and rewrite the program and data memory in your AVR microprocessor without even removing it from the application circuit. This kit connects to the computer serial port, uses royalty-free software available on the

Internet and allows you to program a multitude of micros in the AVR

8-bit RISC family (see website for full listing). Kit supplied with PCB, jiffy box with silk-screened lid and all electronic components.

AVR ADAPTOR BOARD KIT

KC-5421 $20.50 plus postage & packing (To suit KC-5340)

A low cost method of stand – alone programming for when the application board is unavailable or doesn’t include an ISP (or JTAG) header. Program, erase and rewrite the program and data memory in your AVR microprocessor with this socket board. Kit includes everything you need to support in-system programming, PCB with solder mask and overlay, clock source and microcontroller IC socket. Designed in conjunction with KC-5340 AVR ISP Serial Programmer.

SMS CONTROLLER

MODULE

KC-5400 $31.95 plus postage & packing

Would you like to be alerted via SMS when your burglar alarm has been activated, and which sectors too? How about being able to also reset the alarm if you are confident all is fine? It may seem futuristic, but it is all possible with the SMS controller module. By sending plain text messages, you can control up to eight devices. At the same time, it can also monitor four digital inputs. It works with old Nokia handsets such as the 5110, 6110, 3210, and 3310, which can be bought quite cheap if you do not already own one.

• Requires a Nokia data cable which can be readily found in mobile phone accessory stores.

• Kit supplied with PCB, pre-programmed microcontroller & all electronic components.

PC INFRARED TRANSCEIVER KIT

KC-5323 $13.95 plus postage & packing

Did you know that most

Pentium-class motherboards include infrared support right out of the box? This quick and easy kit plugs into your motherboard to provide IR support for external devices such as notebook computers, PDAs, digital cameras, data samplers - and the list goes on!
