SIR-KIT ELECTRONICS HAS TRADED FOR OVER 28 YEARS
Welcome to all our visitors.
We have lots of useful items for students and people who want to teach themselves basic electronics using our simple electronic kits. You'll find everything you need to help study basic electronics whether for an exam or as a new hobby or often for an existing project.
I have posted a mains to 110 VOLT TRANSFORMER on my COMPONENTS PAGE which might be of interest to some people. Also a new goody bag of REED RELAYS. ONLY £1 for 4 RELAYS.
Check our components page for details of our SPECIAL OFFERS which are surplus stock from businesses that have closed, and are especially good value. Also a new page has been added to display various vintage electronics related items, including a GEC BC3520 radio and a Vidor CN 353 radio. There are also some old Wireless World magazines, a Telefunken tape recorder, 2 WW2 Morse keys and a pair of WW2 headphones. Click this link to visit the new page:-
We have a variety of torch bulbs which are useful for all kinds of low voltage lighting projects. Our bargain EXPERIMENTERS GOODY BAGS which contain loads of components useful for circuit development are proving very popular. Check our radio page for some interesting radio projects.
We look forward to your e-mails (we enjoy trying to help people with electronics related problems). Recently we helped solve problems for people trying to develop circuits for specific purposes.
I spent about 20 hours building a robot kit for my grandson a couple of years ago. It has shown me just how poorly thought out some of these imported kits can be. There were serious errors in the instructions and many of the screws could not be placed where they were meant to be due to severely restricted space. However I'm not easily defeated and with a few modifications and a lot of patience I completed it. It said "suitable for 14+" but I found it difficult with 58 years of experience!

joined using short croc clip leads.
All the best from Sir and his team.
ABOUT SIR-KIT ELECTRONICS
This Mail Order business was started in 1988 to provide a simple, inexpensive and practical system for learning basic electronics, for students studying for GCSE exams. It also proved to be very popular with people who wanted to start electronics as a new hobby. Since starting this web site, 16 years ago, we have begun adding information pages which we hope will grow into a useful resource for people who are relatively new to the hobby and for those involved in electronics education.
The following is a brief description of what you can find on each of the pages on this site.
This page describes the system (INPUT, PROCESS [or Control] and OUTPUT) and has a simple system diagram and photos of some built up kits.
This page has lots of links to sites that I have found useful and informative. Most are electronics sites but some are for web site building and others are of general interest.
SERIES ONE KITS basic electronic kits for sale.
This page shows our analogue circuit educational kits. Including sensor circuits (temperature, light and moisture), transistor switch, darlington, schmitt, 741 op amp (operational amplifier), dc amplifier, time delay, thyristor latch and output circuits including relay (and relay latch), motor, lamp and LED.
SERIES TWO KITS simple electronic kits for sale.
This page shows our flip-flops (bistable, monostable and astable kits) using both the 555 integrated circuit and the transistor.
This page has a range of electronic components for sale including:- wire, solder, switches, resistors, capacitors, diodes, transistors, integrated circuits, light emitting diodes (leds), bulbs, relays, motors, thermistors, light dependant resistors (LDR), battery holders, battery clips, crocodile clips, stripboard, breadboard, project boxes, transformers and potentiometers. This page carries special offers from time to time (when available), and our new goody bags.
This page contains a range of value for money electronics hand tools including pliers, screwdrivers, wire cutters, wire strippers, soldering iron, tool sets and special offers (when available).
This page shows our 'build your own' led torch kits.
This page shows our led night light & torch economy conversion kit.
This page shows our simple, 'build your own' radio kit and a small amplifier kit which can be used with it, or to amplify other sources.
This page has a printable order form with ordering details.
Why don't we offer Pay Pal or credit card payment facilities? The simple answer is that although many of our customers are adults we are mainly aiming at teenagers who don't own credit cards, but more importantly we want to keep our prices affordable on teenagers pocket money. The cost of credit card processing must be passed on to all customers (most companies hide this charge in their prices).
This page contains advice on building our electronic kits (which may be useful to anyone new to the hobby of electronics). The resistor colour code is shown here. We have included a guide to good soldering practice (HOW TO SOLDER). This page also has a Stripboard Planner, which is a diagram you can select and print so you can plan layouts of your own circuits on stripboard.
This page shows an example of how to set out the development of your electronic circuits for your GCSE project and how to prototype with our kits.
This page contains 2 worksheets and printed circuit masters (for a plant moisture sensor and a thyristor latching circuit) for use with Key Stage 3 (or possibly KS4) Technology classes. Others may be added at a later date if I get good feedback from people who use this page.
