- Welcome to the TestGear projects.
- ---------------------------------
-
- If you are an amateur electronics enthusiast you will find that you
- require test equipment to set up and calibrate your construction projects.
- This equipment can be expensive and may even be difficult to operate.
-
- What I have done is to set out a series of construction projects where a
- previous project may be used to calibrate the next project, each project
- getting progressively more difficult. All the projects will be some form
- of test equipment used in the electronics industry.
-
- Every project will be designed, built, tested and used by myself to prove
- that it works and cells or batteries will be used for calibration, so make
- sure that you have at least a 1.5 Volt cell available for test purposes.
-
- The only assumptions (one must NEVER make assumptions) that I am going to
- make are that YOU have a MultiMeter (MultiTester) and a little knowledge of
- electronics, the ability to solder, and the ability to build projects.
- Age is unimportant so long as you are competent. I may design a MultiMeter
- but as these are extremely cheap it would be better to purchase one.
- If you have limited knowledge on project construction, soldering, testing
- etc.. then go to your local library for books on the subjects.
-
- These projects will be based around a Standard AMIGA A500 (unless stated
- otherwise) or better, using WorkBench 1.3x or better. Some projects may
- require WorkBench 2.0x or better.
-
- The projects are all in numbered directories. The only one that you can
- ignore if you require is ~Project1~ but ONLY if you have already downloded
- it as TestCard.lha and TestCard.readme from Aminet. If you have not got
- this project then start your building from here. The hardware for the
- first few projects is very simple indeed.
-
- The way to gain experience is to build your own equipment. This gives you
- a firm basis to start a career on, if electronics is what you want to do.
-
- Have some enjoyment and start building....
-
- ----------------------------------------------------------------------------
-
- A few DO's and DO NOTs:-
- ------------------------
-
- 1) Do NOT plug any equipment into the Amiga's socket(s) without turning off
- the Amiga first.
- 2) Do NOT leave the soldering iron ON when it is not in use.
- 3) Be careful when using any etching fluids.
- 4) If an external supply is required then do NOT reverse polarity the
- connections.
- 5) DO, thoroughly check all of your work before powering the project up.
- 6) DO take great care when using glues and solvents.
- 7) Read the ~WARNING~ file.
-
- ----------------------------------------------------------------------------
-
- How to get started:-
- --------------------
-
- 1) Open up a CLI or SHELL window.
- 2) Type the following
- format drive df0: name TESTGEAR noicons<RETURN>
- where <RETURN> is the ENTER key.
- 3) At the prompt put your blank disk into df0: then press <RETURN>.
- 4) Unarchive TestGear1.lha to this disk.
- 5) When finished double click on TESTGEAR.
- 6) Double click on a project and start building.
-
-
- NOTE:-
- ------
-
- If you are using a standard AMIGA A500 with 512KB of memory only then the
- programs may run slowly. This is the trade off for making these programs
- work with most of the WorkBench versions available.
- Also each set of projects should fit onto a standard size AMIGA floppy
- disk, so you should be able to download from AMINET and unarchive to
- ~DF0:~ without placing them onto your hard disk drive. Lastly the projects
- do NOT require any special ASSIGNMENTS and will run straight from their
- own directories.
-
- ----------------------------------------------------------------------------
-
- This is a list of future projects:-
- On Disk2:-
- ----------
- 1) Stereo LF Audio Function Generator.
- 2) Analogue to Digital convertor (required from now on) to run with
- most of the projects to come.
- 3) Audio Power Meter, (1 to 100 Watts into 8 Ohms).
- 4) Simple RF Probe.
-
- Each will get progressively longer to develope but I will get there in the
- end. An Oscilloscope is on the way.
-
- You will notice that the projects are not pretty to look at but they are
- highly functional. That is, they do what they are supposed to do without
- any unwanted whistles and bells.
