Hi, this is Archer 72,
|
|
and I'd like to thank HPR for providing the servers to record to.
|
|
This is going to be a little bit all over a place,
|
|
but HPR was asking for shows,
|
|
and they had a little bit of things to say,
|
|
so I wanted to talk a little bit about my interest in electronics.
|
|
Started when I was 10,
|
|
I found a train set in the basement,
|
|
and decided to set it up.
|
|
It was just a little old track,
|
|
and I had a really basic transformer,
|
|
and I didn't do much with it after that.
|
|
I played with a couple of little engines,
|
|
and oh yeah,
|
|
and I forgot the very first time I got any taste of electricity,
|
|
so to speak, was when,
|
|
according to my instructor,
|
|
I felt a sine wave at three years old
|
|
when I couldn't keep my little hands out of the power outlets.
|
|
And thankfully in the US,
|
|
where the house voltage is 110 volts and about 220,
|
|
I managed to survive.
|
|
A few years later,
|
|
I get a bigger power supply of transformer,
|
|
and more complex layout,
|
|
which I make foldable
|
|
out of the way at the ping pong table,
|
|
which also folded down,
|
|
so that we could have some family time.
|
|
I didn't have a way to simulate this train,
|
|
fully starting and taking time to stop,
|
|
so I added a decent sized capacitor at the track output.
|
|
I think it was about a thousand microfarads.
|
|
That was also when I learned a solder,
|
|
because the rail connectors would have intermittent contact.
|
|
I'd also have,
|
|
to use a heasing clip in order not to melt the track,
|
|
plastic track ties.
|
|
I also made up custom levers
|
|
that went through the plywood to activate tracks,
|
|
which is with solenoids.
|
|
I remember correctly,
|
|
there were catalogues for MCM electronics
|
|
and all electronics,
|
|
which I'll include in the show notes.
|
|
And at this point,
|
|
I think MCM electronics
|
|
became another company like Newark.
|
|
That's where I found the parts
|
|
for this and other projects.
|
|
I still have a bunch of atrial scale cars and engines
|
|
in my parents' house.
|
|
When I was building this layout,
|
|
I learned how to use a hot resistance wire,
|
|
my dad,
|
|
and we cut Styrofoam
|
|
as a base for some of the scenery.
|
|
Also, I did a lot of bit of wire framing
|
|
to do some of the inclines.
|
|
And for realism,
|
|
I was in a crushing of coal with a hammer
|
|
to make realistic size pieces
|
|
for the co-oppers.
|
|
I should have actually used a mask,
|
|
because I breathed in a lot of dust in that process.
|
|
I dumped my midteens.
|
|
I was still on the trains,
|
|
but I took more to building circuits
|
|
from any engineer project books.
|
|
They had a radio shack.
|
|
And there's archive.org,
|
|
like the guy I could put in the show notes too.
|
|
My favorite project at the time
|
|
was a mini-stun gun
|
|
that I made using a pre-built inverter
|
|
from the catalogs that I had mentioned.
|
|
And I put it,
|
|
provided a hundred volts
|
|
from the inverter circuit.
|
|
And I ran into a,
|
|
I think it was called deck stacked
|
|
a bluer circuit.
|
|
The result was a 1,200 volts
|
|
at a few micro-amps,
|
|
as far as I can measure.
|
|
And in a couple of moves,
|
|
I managed to lose it.
|
|
I wish I had it around.
|
|
I continued my interest
|
|
when I was building
|
|
an electronics one.
|
|
I was building speed carrying closures
|
|
for a sound system
|
|
in my 1986 Chevy celebrity
|
|
station wagon,
|
|
which was my first car.
|
|
I ran a high-amperage cable
|
|
across one fair-eyed capacitor
|
|
to account for the amplifier's current draw.
|
|
And I built a custom board
|
|
to hold those amplifiers
|
|
that fit in the rumble seat of the wagon.
|
|
In 1985,
|
|
I was about the same time
|
|
I was working with the car amps.
|
|
And I had my first long-time job
|
|
in the printed circuit board industry.
|
|
I walked on the mechanical assembly
|
|
for a year.
|
|
And I myself and the SMT
|
|
department are asking around
|
|
and SMT is surface mass soldering.
|
|
And I asked to learn how to do
|
|
the SMT soldering and repair.
|
|
This lasted about five years
|
|
until I moved on to a medical
|
|
device from manufacturer Baxter,
|
|
which is spelled Baxter Healthcare.
|
|
Here are the robust
|
|
infusion pumps for about six years.
|
|
These pumps would be set
|
|
for a flow rate for vinyl fluids,
|
|
of course electronically,
|
|
through a keybed.
|
|
You know, detect air pockets
|
|
if the tube was pinched off
|
|
or if the patient laid on it in the bed.
|
|
I had a variety of jobs after that,
|
|
mostly in contracting and manufacturing
|
|
for PCB boardhouses.
|
|
The last job before this
|
|
was working on machines
|
|
that analyze trace amounts of nitrogen
|
|
to packaging environment.
|
|
All right.
|
|
Now they make floats
|
|
where most of them make use
|
|
or actually all of them make use
|
|
of a sensor package
|
|
for temperature pressure and salinity.
|
|
It depths of 2,000 meters
|
|
to study environmental issues.
|
|
They have room for other packages
|
|
if they have to do custom jobs
|
|
for other clients.
|
|
And up is a result
|
|
in not the same thing,
|
|
just one of them was
|
|
to study hurricanes.
