First of all here is a useful piece of test equipment that i designed many years ago. Decorating christmas tree with leds;
Everything you need to design a work space, use test equipment, build and troubleshoot circuits (tab electronics technician library):
Build your own electronic test equipment. This bit of the website has a few items you might want to build. Build and simulate circuits right in your browser. Then, you can build your own as needed.
This section will list several projects which will allow you to build your own rf design test equipment. Analog & digital circuit simulations in seconds. Launch circuitlab or watch a quick demo video →
In recent years, linear supplies have gone out of favor due to the more efficient switch mode type of supply. Launch it instantly with one click. You can get your hands dirty with microprocessors, development boards, soldering, and tinkering.
I have personally built some of the equipment in the book and have found them indespensible in my home workshop. Choose from hundreds of electronic kits or assembled circuits for your diy , school, or. One word of caution here.
However, when you have ac outlets everywhere, efficiency is not a great concern. Also, if you do build your own, even the most skilled homebuilder will not have enough years to build a truly equivalent, modern amateur radio station. Build your own lc meter and start making your own coils and inductors.
Examples of diy test equipment include oscilloscopes, function generators, audio impedance meters, capacitance meters, ac/dc led indicators, 554 timer ic tester, digital frequency counters, digital pressure guage,. If you are working on printedcircuit boards a 25 watt pencil sized iron is appropriate with tips 1/8th inchor smaller. Here's everything you need to.
You can use almost any audio amplifier ic with this circuit (with appropriate pin changes). Professional schematic pdfs, wiring diagrams, and plots. Over 100 new robotic kits, electronic kits, test equipment, snap circuits, science kits, and stem approved alternative energy kits.
Hams to build their own has almost vanished. Step one is to have the propersoldering iron, solder and technique. Plug the valve to be tested into the appropriate socket and also the correct banana plugs for the pinout of your valve if you are using the mk ii tester.
This book is an excellent source for inexspensive test equipment for both hobbiest and professional. The thing with making your own measuring and test equipment is that you may not be able to guarantee it's accuracy and calibrate it against anything unless you have some test equipment. Multimeter, swr/power meter, dip oscillator, rf signal generator, cathode ray oscilloscope simple test equipment to build a field strength meter, a crystal tester and a capacitance meter by peter parker vk3ye dual output 200 mhz rf generator/detector
The soldering iron's tip size andwattage should match the size of the job. Outlined in the book are instructions for building equipment to test audio components, tv's, vcr's, and communications devices. A guide to test equipment that just about sums up many peoples attitude towards test equipment.
Controlling safe current flow through leds; Electronics, arduino, and robotics projects don't necessarily require a dedicated workstation, but it certainly doesn't hurt. If you are a design & electronics enthusiast, this is an opportunity to make homemade tools & instruments that fits your needs, at a fraction of the price of more expensive equipment.
This lc meter allows to measure incredibly small inductances making it perfect tool for making all types of rf coils. The commercial units contain custom integrated circuits, custom cabinets and are the end result of multiple prototypes and exhaustive testing. The last thing your test bench needs is another source of rfi, so stay with the linear supplies.
If you're getting started, diy test equipment is a fun way to explore design & electronics projects, while making something useful. Build your own electronics workshop: The idea for diy test equipment comes from dougw.
A basic signal generator is a good idea. Make an efficient led emergency light; More serious led projects, which are listed at the later part, help you build useful circuits like emergency lights, electronic tube lights, car roof lights, etc.
Although if you have a scope you've got the first piece of more or less precision equipment You'll need basic electronics construction tools and a bit of practice to build them. Pwm controlled white led driver circuit explained
To use the tester, look up the characteristics section of the valve datasheet for your valve.
