This MPPT charge/Light controller will work with 12V or 24V solar panels to charge a 12V or 24V lead-acid or lithium iron phosphate battery. you can then use the battery to run 12V dc lighting.

(SC May 2010) Amplifiers which run from 12V DC generally don't put out much power and they are usually not hifi as well. But this little stereo amplifier ticks the power and low distortion boxes. With a 14.4

(SC November '08) This small circuit can be used as a speed controller for a 12V motor rated up to 5A (continuous) or as a dimmer for a 12V halogen or standard incandescent lamp up to 50W. It varies the power to the load (motor or lamp) usi

(SC June '11) This gutsy little speed controller has a wide range of applications and is simple to build and use. There are no software settings to fiddle with but it does have some really useful features such as low-battery protection, soft start

(SC Jan-May '17) This completely new amp design incorporates most of the features of Silicon Chip Ultra-LD Mk4 200W amp but uses easy-to-solder through-hole components - no SMD!

(SC Dec 2004) Extremely simple amplifier kit designed to be easy enough for beginners to assemble. Delivers 20W RMS and is suitable for small hi-fi applications or a PC sound system.

(SC October '10) Brings your Christmas light show to life! Lights will flash, dim up & down in time with your favourite Christmas carols. Power up to 32 channels of lights from a master unit & 4 slaves.

The Brownout Protector is designed to protect single-phase induction motors in fridges, freezers, pumps etc from burnout if they attempt to start during a brownout. It will switch off the power if the voltage falls below a set threshold.

(SC April '12) Are you alarmed by the juicy "splatt" from your mains power point when you plug in something like a large plasma TV set? Do you sometimes burn out light and power point switches because of

This mono version of Silicon Chip’s new equaliser is perfect for instrument boxes or PA systems. It features extremely low noise and distortion, so it won’t degrade your signal. Multiple methods of powering the unit make fitting it into an existing system a breeze.

This stereo version of Silicon Chip’s new equaliser is perfect for new and existing home Hi-Fi systems. It features extremely low noise and distortion, so it won’t degrade your signal. Multiple methods of powering the unit make fitting it into an existing system a breeze.

(SC January 2013) A fully upgraded and redesigned version of the 'Champ Amp'. Delivers up to 7 watts of peak power with lower noise and distortion levels. It also offers muting and standby control, plus two

(SC Feb '94) Physically about the same size as a standard 9V battery, this compact little amplifier delivers 0.5W of power into 8 ohms from a 9V battery. Ideal for beginners, experimenting and small audio projects.

High quality friction fit clear acrylic case designed to fit the K5192 Stereo Hifi Valve Preamplifier kit.

(SC July '94) Designed to compliment the K 2115 Champ Amplifier When it comes to simplistic but effective circuitry design, you can't beat the pre-champ. It has been designed to compliment the CH-AMP kit which when

(SC January 2013) Designed to complement the K 6066 Champion Amp kit. Utilises a low voltage op-amp IC with considerably better performance than the old 'Pre-Champ'. Provides added gain to your signal whe

(SC Nov '12) This high specced power amplifier operates in Class 'D' as opposed to earlier amplifiers which run in the more conventional Class 'AB' or Class 'A'. The new Class 'D' amplifier offers the extrem

(SC June 2010) This linear bench supply can deliver up to 1.6A from positive & negative outputs with a range of +/-0-19V. It has adjustable current limiting for both outputs and can display the voltage

Ideal for automotive fault-finding * Set for any current between 315mA and 10A. This resettable Electronic Fuse (eFuse) can be used temporarily in place of a conventional fuse when fault-finding.

(SC April '04) Allows quick "in-circuit" detection of defective electrolytic capacitors. 0.01-99Ω autoranging. Includes case & fully screened & punched front panel.

Do you hate carrying keys? The Fingerprint Access Controller can store and recognise up to 20 fingerprints and can give access to your home or workplace at any time, day or night.

This simple and cheap device has many uses, but it’s mainly intended to replace multiple panel meters. It can also be used as a small additional text screen for PC, Raspberry Pi or any other computer with USB.

The guitar preamp when combined with any amplifier will produce crystal clear guitar sound free of the usual hum and noise frequently experienced on commercially produced units. With options to expand the unit to tw

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 th

This large and powerful Ultrasonic Cleaner is ideal for cleaning bulky items such as mechanical parts and delicate fabrics. It’s also quite easy to build and is packed with features.
