This is HBR Episode 2008122 entitled What's in the Box.
|
||||
Part 1 and is part of the series, Hobby Electronics.
|
||||
It is hosted by NY Wheel and is about 21 minutes long and carrying a clean flag.
|
||||
The summer is, and it will open the mystery box, if found in the mailbox.

|
||||
Hello, this is NY Bill and I'm here with, I don't know what I'm here with, actually, two
|
||||
weeks ago Box arrived in my mailbox and I know who it's from now because they sent me
|
||||
a question, I think it was signal asking if it had arrived or if it, but it takes a
|
||||
little while to get this game all the way from England, it came from Cornwall, it came
|
||||
from Mr. Tim Timmy and I have no idea what it is.
|
||||
I've just put it on my bench and he kind of hinted that it might be electronics in nature,
|
||||
so I said when I get some time to record, I'll open it up and I'll, let's see what this
|
||||
is.
|
||||
I'm going to open the window while we can listen to the rain now, but it's hot in here.
|
||||
It's finally getting towards spring.
|
||||
Oh, drop my ball.
|
||||
So let me get a knife and see what's in here, where do I start opening it?
|
||||
I guess I don't start opening it, I just peel off Marshall, did you completely cover
|
||||
this tape as a joke?
|
||||
I don't even get in here.
|
||||
Watch, I'll get through all this tape and he'll have sent me a box of tape, that would
|
||||
be.
|
||||
I'm going to call this episode tape.
|
||||
Finally, holy cow, no, he's got tape going in the other direction too.
|
||||
If you can hear a card doorbell, that's one of my buddy's sent me a text.
|
||||
Marshall, I'm going to edit this so everybody doesn't have to listen to it, but I'm going
|
||||
to send you the raw, because this is 3.45, 3 minutes and 45 seconds of me opening tape,
|
||||
buddy.
|
||||
You're going to have to listen to it all.
|
||||
It's in an HP box.
|
||||
It's in a toner box.
|
||||
He sent me some crunch bang stickers, awesome man.
|
||||
Wow, that brings back memories.
|
||||
He's still had some of these, huh?
|
||||
Cool.
|
||||
One of those is going right on the new laptop, because I didn't have one.
|
||||
What is this?
|
||||
Oh, sweet.
|
||||
It looks like a guitar pedal kit.
|
||||
A tremolo.
|
||||
Awesome.
|
||||
Yeah, I do like these.
|
||||
Tremos.
|
||||
I had one way back in the day by boss.
|
||||
Wow, this is a lot of parts.
|
||||
Thank you, man.
|
||||
Yeah, we'll get an HP R or two out of this.
|
||||
The build of this.
|
||||
Debian volume.
|
||||
It's a complete kit.
|
||||
That's awesome.
|
||||
Nice.
|
||||
I'll just open it up a bit here.
|
||||
Let me check and take a look at the board.
|
||||
That looks pretty straightforward.
|
||||
Cool.
|
||||
Well, this might be a short HP R, but I have to build this thing now.
|
||||
I hope it doesn't work the first time, and I got to fix it.
|
||||
That'll be good.
|
||||
All right.
|
||||
It takes Marshal.
|
||||
That's awesome.
|
||||
So I just went down and showed Mrs. NY Bill, and she said, who knew guitars needed pedals?
|
||||
How do you think they get all the noises here?
|
||||
Oh, Mrs. NY Bill.
|
||||
So I thought, you know, I'll build this up someday, and then I realize it's raining out.
|
||||
There's nothing to do.
|
||||
I'm going to start building it now.
|
||||
It's fun.
|
||||
The instructions are minimum.
|
||||
They just show where each component goes.
|
||||
So I'll build this up like I do all my boards, lowest components first, and then stack
|
||||
up.
|
||||
I wonder why there's so many LEDs.
|
||||
Oh, no, just the one LED.
|
||||
All right.
|
||||
So let's see what we got here.
|
||||
Magnification, because I'm getting old.
|
||||
Transistors.
|
||||
I wonder if they're doing like a push pull thing with the transistors.
|
||||
And resistors.
|
||||
I'll start with the resistors.
|
||||
Well, I'm going to have to edit some of this out because I'm in a long text conversation
|
||||
with a bunch of friends from the look.
|
||||
My buddy, B. Spamike, is a Lenovo fanatic.
|
||||
So I'm just, he says he's going to start cleaning his house and start actually getting rid
|
||||
of stuff.
|
||||
But I just told him I picked up a pallet of Lenovo's from an old school, and he's going
|
||||
to want that.
|
||||
Let me send it.
|
||||
All right.
|
||||
Yeah, it's like, what is this episode going to be like, an evening with Bill?
|
||||
All right.
|
||||
Let's open up these resistors.
|
||||
Well, I'm curious where you got this from, Timmy.
|
||||
I had a tremolo once, a boss tremolo, and it was used, and it worked fine in the store
|
||||
when I got home.
|
||||
I started doing this weird, I think it was a ground loop.
|
||||
So like a weird buzz sound to it, but the buzz was in the tremolo, like, yeah, that's
|
||||
what a buzz sounds like in a tremolo.
|
||||
I wonder why I got so many of these leads up to the, yeah, up to the pots, of course.
|
||||
So that's nice.
|
||||
They labeled the resistors for you.
|
||||
They don't have to get out a meter and check each one.
|
||||
Well, I'll pause it here while I populate some parts.
|
||||
20 meg.
|
||||
I might have to put this one on the meter.
|
||||
I can't read the writing of whoever wrote very tiny on your 20 meg, or 2.2 meg, probably
|
||||
2.2.
|
||||
I'll just save that one to last.
|
||||
This is something I do.
|
||||
If you're not sure of a component's value, or it's like, way in between something, just
|
||||
leave it to the last one you put in, and it might, you know, it's going to be the last
|
||||
slot on the board.
|
||||
Yeah, it's hard to read this person's writing 10k, I think this is.
|
||||
I'm going to check a few of these.
|
||||
Let me turn on the meter, ohms, 1.2 k ohms, when you're here's a tip, when you're using
|
||||
a meter to check resistance, your tendency is to grab both leads and push them down onto
|
||||
the probes with your thumb.
|
||||
You're actually going to start reading the resistance in your body as well.
|
||||
So if I hold this one, I'm only holding one end, and I got 1.2 k ohms, but if I touch my
|
||||
thumb on the other end as well, it goes down to 1.1 k ohm, that's not much, but I am changing
|
||||
the resistance by using both my thumb.
|
||||
So that's 1.2 k ohm, all right, it goes there, here I'll check this one, that one I said
|
||||
I'll save the last, let me just check it while I got the meter going, so it's 0.8, no,
|
||||
2.2 mega ohm, yeah, 2.2 so that's a 2.2, it goes right there, all right I got it.
|
||||
Did you buy one of these for yourself, Marshall, to build as well?
|
||||
I know you're into guitars, and I know you're a guy that's not afraid to solder, or did
|
||||
you build one already?
|
||||
All right, there's the resistors populated, I got the wrong tip in my, I got a tip I
|
||||
don't want in my soldering iron and it's already hot, let's try that again, I'm trying
|
||||
to clip the leads of the resistors and get them all to fall in the box, but inevitably
|
||||
one goes flying off and it's in the rug somewhere and it'll stick in my sock and some
|
||||
future date.
|
||||
Oh, look at that, 2 I forgot the solder, well clipping them off I just sold 2.
|
||||
When you bend the pins over on like all the resistors at once it's like a little forest,
|
||||
sometimes you can't see a couple in there, just put it back in the stand and I lost it
|
||||
again, there's it, maybe it was just the one, oh there it is, all right what's next, next
|
||||
biggest thing, next biggest thing is the transistors, so what do we got here, I got to look
|
||||
under the, we got 2N 3904's, 2N 3904's, I'm going to go look up what that is, but 2N
|
||||
3904 is a NPN transistor and they're look, let me look at the traces, they're putting
|
||||
them in, kind of back to back here, then there's one other transistor, a K30A, I've never
|
||||
heard of this, oh it's a fat, now I've never heard of this one, so this one goes in down
|
||||
here, there's the transistors, next up in height-wise is, oh these look like a little
|
||||
tantalum, tantalum capacitors, oh they're dipped, they look like they're just dipped in
|
||||
some type of plastic, these are 105's, and then we got another, this looks like a tantalum
|
||||
there's a little tantalum, 1.75224, what the heck is that, oh it's 224 over here, all right
|
||||
I got to open up another package of, what's all this, this is all the pots and the LED,
|
||||
I don't know, here's a 3-pole double throw switch for like a true bypass, I'm not sure
|
||||
if these are directional, I guess I have to check them with them either, I'm gonna put
|
||||
that in last, that's pretty tall, got some pots here, here's an LED, on these instructions,
|
||||
I'm not sure what's going on here, it looks like they've drawn two bodge wires from the
|
||||
3-pole double throw down to the 1-meg resistor, and then they crossed it out, and then
|
||||
they've drawn another one between the 1-micro-fared cap and the center leg of the transistor, and
|
||||
then they've crossed it out, so I don't know if, I don't know if you need to put those
|
||||
jumpers in, or they didn't, and they didn't, or Marshall did you buy one of these kits and
|
||||
put it together and it didn't work, this might be like long distance troubleshooting,
|
||||
let's see, okay, it just took a little while to kind of figure out these pots, you've got
|
||||
a D1D2D3, you've got a V1D2D3, and an S3S2, okay, speed volume depth, and it doesn't
|
||||
tell you which wires to use for what, so I'm just gonna make it up, I'm gonna put, in all
|
||||
the one positions, I'm gonna put black, they give you black red and white, oh speed
|
||||
only gets two wires, so it's only got speed only has two and three, for two I'll use red
|
||||
I guess, and then S2, the speed does have a number two right there, boy this just reminded me
|
||||
I started another, I think it was another HBR I did where I was talking about etching, and
|
||||
I etched a board for a big muff pipe pedal, a distortion pedal, and I never finished back, it's
|
||||
still over there, it's over near my computer, it's just not a case yet, and I haven't tested it,
|
||||
maybe someday, so the three wire, D3, those are all, I'm gonna have to be white, so here's S3,
|
||||
I was soldering the wire, and when I let go of everything the wire fell back out, so I gotta
|
||||
clean this all up, LED plus LED minus, plus I'll do red, minus I'll do black, last thing
|
||||
is the switch I'm gonna put in here, because it's big hunk and switch, so the pins on this
|
||||
are pretty heavy duty, if you're soldering something like that, put your soldering pan on one side
|
||||
of the heavy duty metal, and then bring your solder into the other side of that metal, so you get
|
||||
everything up to the same heat, it's kind of like the way plumbers do a coupling or a joint,
|
||||
now I just got to remember which one of these was what, we got three different parts,
|
||||
500mg, the one that wasn't labeled is the 500mg, that is for depth, so depth 123, oh that's a tricky one,
|
||||
let me take a picture, so I got the potentiometer up in the vice, and then I gotta just bring the
|
||||
leads up with my thumb and finger, that's a trick, okay I'm gonna do the barrel jack now, but I
|
||||
don't know which one is, which pin is what, so I'll get it on the meter, touch the center pin,
|
||||
okay so there's a bent over tab, if anybody gets a kit like this, that's your center pin,
|
||||
and then there's two other tabs, those are both ground, and then the last thing here is the LED,
|
||||
short leg is the cathode negative, I don't want to shrink wrap these, okay just found,
|
||||
I'm glad I caught this now, I have soldered the LED negative to the volume in one side of the
|
||||
volume, let me fix that now, just we just lose a whole troubleshooting episode because I found
|
||||
that already, okay I think that is the whole thing, it looks like an octopus on the bench here,
|
||||
the big question is will it do anything, let me go get an eyeball battery, and I guess I'm
|
||||
gonna have to turn on an amp and find a guitar and some chords, all right I got my trusty telly,
|
||||
okay I need one more guitar cord, this thing ready to go, the amp is ready,
|
||||
so which one of these is output, tip out, it's doing something,
|
||||
it's just making a buzzing noise, where I need another chord, just all went on the floor,
|
||||
out, tip in, well we got, I can play through it, let's see what happens,
|
||||
the volume just went down,
|
||||
there is no tremolo,
|
||||
so we start troubleshooting, also the LED does not come on, there's a difference,
|
||||
is that the volume, volume's working, but no tremolo, all right let me check into this,
|
||||
I think, well I just found something already, I went to pick up the board and the
|
||||
negative wire from the battery, just go right out, it's not soldered in,
|
||||
it's, well I got a little solder on there, but not enough, so the only thing working on this
|
||||
is the volume, let me see, do I have my LED backwards maybe,
|
||||
usually an LED is just an indicator, but sometimes they do run circuits through it,
|
||||
well I'd say basically the build is failure, it's doing a little something, but not the right
|
||||
something, so I guess we get another HPR out of this, as I do a repair episode, so that'll be
|
||||
a part two I guess, thanking you Tim Timmy from like a long distance and like holding my arm out
|
||||
along, should I thank you for this, or is this going to be down the rabbit hole, all right,
