NoBrand K6330

DC-DC Converter 3-9V :: K6330

Say you want a 9V battery to supply 40mA to a circuit. That's a pretty modest current but if you use a PP3 style 9V battery it won't last long at all. In fact, if you're using a typical “heavy duty" 9V battery, it will last less than 20 minutes before the voltage drops to 7.8V. That may be enough to stop your circuit working. Or maybe you are using an alkaline type. Depending on the brand and price, you might get about two hours life. Not good.

By comparison, two AA alkaline cells driving this DC-DC Converter circuit to give 9V at 40mA will last about 7 hours. And rechargeable AA cells can be even offer better performance.

This circuit can deliver up to 90mA at 9V (with less life from the cells) or can be set to deliver anywhere between 4.5V and 20V. You might never have to buy another 9V battery ever again.

NoBrand K9300

RFID Entry Tag Kit - Requires 12V DC Power Supply :: K9300

Essentially, the system consists of a reader module and one or more "tags". Based on RFID (Radio Frequency Identity) technology, each tag is encoded with a unique identity.
When a tag is brought within range of the reader, it is energised by the reader's magnetic field. It then transmits its unique code to the reader, which validates the code and arms or disarms the alarm system accordingly.
This system also includes the ability to operate an electric door strike. A simple wave of your hand and an "Open Sesame" incantation are all that are required for the door to your castle to spring open!

Features
Contactless operation
90-100mm detection range
No batteries (in tags) to go flat
Stores up to 24 tag ID codes
Easy tag addition & removal
Works through any non-metallic material

2 Way Active Crossover Kit - Requires ±15V DC Power Supply :: K5570

(EA May ‘92) This great kit enables you to customise your sound system. The circuit simply connects between the audio source and the amplifiers. There are two outputs, one for bass and another provides signal for the upper range. Thus each amp is dedicated to a frequency range (i.e. one for bass, one for midrange and treble). Because no passive crossover is required there are no losses involved. Suitable for live PA or Hi-Fi applications. One per channel is required. Operates on ±15V rails. The result is much better sound with less distortion. Comes with a range of resistors to select the crossover frequency between 1.8kHz and 3.6kHz.

need to remove it from the PC board. Capacitors can often show very high ESR
levels whilst displaying the correct capacitance on a multimeter. In devices such as
switchmode power supplies, high ESR in capacitors can cause such issues as loss of
regulation, excessive high frequency noise etc. This compact ESR meter is an invaluable
tool for the service technician and can be constructed in just an hour or two.
Supplied with punched & screened case. Requires 6 x AAA batteries.
