YOU FOR BEING VISITOR No

SIR-KIT ELECTRONICS HAS TRADED FOR OVER 30 YEARS
DECEMBER 2018
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 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 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, or order complete kits if you wish. 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 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! 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 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. [home] [sir-kit system] [links] [series one
