THANK
YOU FOR BEING VISITOR No
since
we relaunched the site on webs.com (at the end of 2009)
Site updated 12 JULY 2021
SIR-KIT ELECTRONICS HAS CEASED TRADING AFTER OVER 30 YEARS. PLEASE READ ON AS WE HAVE SURPLUS STOCK FOR SALE AT REDUCED PRICES.
July 2021
Welcome to all our
visitors. STAY SAFE DURING THE PRESENT CORONAVIRUS PANDEMIC. I have just found out that the host for this site will no longer support it after June 2021 (Trying on 12 July). This means I will not be able to keep it updated. Continue to e-mail me for components , help and advice.
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 fun new hobby or often for an existing
project. Our electronic kits are fun to make and fun to use. They also support the practical skills and theoretical knowledge required by major G.C.S.E. exam boards. I have ceased trading as Sir-kit Electronics, but still have stock which I am selling at COST PRICE. You will need to e-mail me if you would like to buy anything shown on this site to find out the availability, cost and how to order and make payment. So I have made all series 1 and series 2 kit instruction sheets available for you to view or download here SERIES 1 KITS and SERIES 2 KITS . Now you can order any parts you don’t already have from me. However I will no longer supply complete kits. . I have posted a mains to
110 VOLT TRANSFORMER on my COMPONENTS PAGE
which might be of interest to some people. I have added a blacklight (ultra violet) fluorescent tube to the surplus components list on that page. Also a new goody bag of REED RELAYS (new and unused surplus stock). These are made by a well known manufacturer and specs are easily found on the internet . ONLY £1 for 4 RELAYS. Normally cost more than £2 each! 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. On this page I am disposing of my private collection of electronic and radio related ephemera.
There are also some old Wireless World magazines and other electronics related magazines, a Telefunken tape recorder, 2 WW2 Morse keys and a pair of WW2 headphones.

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 few 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! No such problems with my Series one and Series
two kits which I designed myself and tested with teenagers. This photo shows a light sensitive
switching circuit using kit 1a, kit 1c and kit 1x 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, over 18 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. SITE INDEX 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. This page now contains the instruction sheets for SERIES 1 KITS in pdf format. SERIES
TWO KITS
simple electronic kits. This page now contains the instruction sheets for SERIES 2 KITS in pdf format. 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 the few tools we still have for sale.
This page shows an led torch. This page shows an led night
light & torch economy conversion kit. This page shows our simple, 'build your own'
radio kit, (unfortunately now sold out), and a small amplifier kit which can be used with it, or to amplify
other sources. This page has ordering details. 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.
