So, a while back I made this chest of drawers of some sort I guess, it's just racks of my
stuff so my stuff doesn't end up laying out everywhere.
Umm.
I guess it does end up laying out everywhere, but it's not as bad as it would be otherwise.
But, this had me thinking - that happened a long time ago.
I have three old racks - of old stuff.
Just things that I don't need anymore.
So I figured I'd go through some of it so you guys could see what I was up to.
One of the biggest projects that I worked on, I guess what got me started with a lot
of this - the glass circuit boards, the circuit boards on silicone conductive material, all
of that was a keytar I was working on.
Let me go get that keytar.
I was going to make this clear I guess uuh acrilyic keytar.
It never worked out.
Spent a lot of time, a lot of effort, never worked out.
Just gave up.
But, there's a lot of cirucits and everything else that was a learning experience out of
that.
Some of the first ones were when I figured out how to make touch sensitive circuit boards
on glass.
I ended up getting my friend Kelsey to make this design.
I have other friends who made other designs.
Umm.
And as you can see it's got ridiculously - let me see how to show this off - a very elaborate
design here.
It was a lot of fun to make.
And I fabricated a couple of these, it worked!
It worked just fine.
By pressing the buttons on the back here, you could play the notes like a keyboard.
And it worked out.
Just wasn't something I could easily integrate into the keytar, so I just gave up and put
it away.
Same thing for the top of the keytar here.
Uuh.
This right here was to go on the point of the keytar.
My friend Sterling Diesel made this one here.
I guess did the design.
I did the printing.
And uuh.
I don't know if I can find it, there's another part of it here.
Along with a brain that I was working on.
And there's a bunch of other failed projects.
Just things I got to print and never really cared much more about.
In fact, I don't even know what this is.
It's got an attiny on it, some mosfets and mosfet controllers.
Who knows what that was for.
I have here my AVR on a microscope slide that could run Minecraft.
Another copy of it.
I have my mounted copy of it.
You know I honestly can't remember what half this stuff is anymore.
I don't remember printing it.
Uuh!
Hey!
This is neat.
This is the predecessor to the AVR on a Minecraft Slide.
It was one of the first ones I made as you can see I had to do a whole lot of jumpers
to get it to work, and it worked.
That's neet.
Umm.
I have a little power over ethernet board.
I have a bunch of left over circuit boards.
A bunch of NeonFM Boards.
Believe it or not the very first batch of Neon FM boards I printed in my own basement.
Eventually I moved up to OSH Park and ITead Studios.
To be fair, I never did any with Osh Park.
I did them all with ITEad studios and electrodragon.
This is one of the early revisions of the RGB boards that go on the Panels for NeonFM.
They've got 24 LEDs on them.
Just like the new ones - and uuh an ATMega.
This one is an ATMega48.
And it uses the old style connector.
We use much better connectors now.
Here's one of the first tests I have for RGB controllers that sit on Aluminium heat sinks.
So, the idea is you print the circuit boards on this silicone thermally conductive stuff
and they're driven by an ATTiny44 and several Bipolar or BJTs, not bipolar.
Hurr.
BJT Transistors in order to drive them to brightness.
And to do that you don't have a PWM, you don't have this on and off pattern.
It's just this brightness control.
Let's see what else?
Ooh, a little AVR Glass Clock.
You guys probably remember that.
Still might work, probably won't.
Don't really are anymore.
Here's another test I tried of using kapton with the LEDs on it for thermal conduction.
Ummm that didn't really work at all.
The silicone stuff was much, much better.
This worked!
It was a little 8x8 LED controller for these LED Grids.
I have a video on that one if you wanna see it's right there.
Let's see here.
Stencils for old NeonFM Parts.
Stencils are pretty neat.
I usually only them if I'm making several of something otherwise I'll just use my old
smear the solder paste on all the pads and it'll work fine.
This right here was supposed to be a button panel for a DDR machine.
I just threw it together quickly and it's a 2 layer board, capacitive touch sensing.
Totally worked.
Umm.
Just never did anything with it.
Here's the first version of the switch mode power supply I used in my flashlight video.
This one worked.
I don't remember why I stopped using it.
As you can see I have a couple more demonstration units I was working on with the silicone.
Uuhh circuit boards.
These all still work as far as I'm aware.
I just used one a few days ago or a few months ago now.
Umm Those were neat.
Let's see here.
Ooh it's an NTSC video board.
I guess I was trying that out.
Dated all the way back to 2011.
Good grief this hobby's been going on too long.
Random AVRs with USB on them...
Umm There's more boards for the matrix LEDs.
Ah!
Look at that!
It's actually an 8751 programmed with a DMX program on it, so you can plug it up to your
parallel port and output lighting.
I did that when I was in 10th grade, I think.
Let's see here, what else?
Oh my.
This was one of my first attempts at RS-485 communication.
This is a touch panel, it's got four buttons, you can click click click click.
And it would communicate over RS-485 what was being clicked.
That worked.
Don't care anymore.
Here's the first version of the PS/2 Synth.
You can see it has here the little PS/2 plug.
I don't know what posessessed me to put it on a microscope slide.
It worked.
It's cracked.
Whatever.
Umm I don't know what that is.
Not sure what that is either, but oh my gosh that's fine pitched.
For a long time I didn't realize that uuh having wider traces is a good thing.
As you can see these traces are itty bitty.
Still, somehow the board worked as far as I remember.
Let's see here, I have more test boards.
This was uuh.
This was one of the keytar except it was done with silicone as the base.
That doesn't work.
You can see here a lot of the traces just started falling off.
It was pretty terrible.
The traces were falling off.
Ooh!
This one is a neat one.
A while back I did a video on touch sensitive AVRs.
This is the very first one I did.
Touch sensitive AVR that is.
Worked pretty well.
Had fun, little ATTiny44 some touch sensitive code.
Here is a more modern cut at the keytar board.
A lot of those glass circuit boards.
Then I also learned you could use ribbon cables.
That really helped.
Now the profile is pretty thin, verses before, it was pretty thick.
Additionally some of those things popped off because they just broke.
Here's another one of them.
I printed a lot of fairly large glass circuit boards.
It was a lot of work and many of them didn't work.
Learned a lot.
Here's the guts from the Nintendo Zapper project I did.
Don't know why I have two of these now.
I do! see here, what else?
Little ATMega328.
Or 32u2 rather.
Little board here, generic break out.
I have here a touch pad my friend Adam designed.
I'm not sure why I didn't make more of these.
It's a touch sensitive, touch pad.
My friend Adam Geary, shows up as a HID device, you click a bunch of buttons and it's like
a gaming keyboard.
Umm actually I probably should do something with that.
Oh well.
Not enough time.
Some random circuit boards.
Ooh!
One of the frist, actually I think this is the first touch sensitive glass PCB that was
completely successful.
Up here we have more stuff.
Oh No.
My light has worked against me.
Okay, so here I've got a bunch of other random stuff.
Here's a thermocouple thing with a USB enabled AVR thing.
As far as I remember I got the thermcouple temperature off, then I got bored and didn't
use that project any more.
This was my first general purpose AVR with magnetometer board.
We use these in Cardiac.
Another game that was created by Unit-E. Same sort of thing as NeonFM.
We don't use that partciular board any more but uuh...
Still fun.
The new boards still kinda have their spiritual successor I guess.
This was a random board I made with a bunch of IO on it.
Just generic.
Has an ATMega168 on it, little ENC424j600.
I never used it for anything.
Also I don't like these contacts anymore where you have to shove a screwdriver in to get
the wires out.
Umm.
General purpose board that has a bunch of connectors on it.
And an ATMega168 so it would use V-USB.
This one I know worked, just never did anything with this.
My roommate did this one.
It was an attempt at making a power over ethernet power supply.
I don't think he ever got that working, but I'm not sure.
I guess that was rev 2.
This might have been a dumb injector, that did work.
Umm I think that was an early neonfm board.
I'm not sure.
I made an optical DDR pad once and this was one of the circuit boards that was used in
it... or part of a circuit board I used in it.
Hey, the armature part of the keytar.
This has a whole bunch of individual sections that you can't easily see and they're all
interwoven and as you move you finger up and down the neck of the keytar it will tell where
your fingers are so you can make audio effects with it.
Okay, I never actually did any of that but I'm sure it could be done if I ever bother
working with that keytar again.
More glass PCBs from the keytar.
More neon fm boards, ooh this is neat.
I made badges for MAGFest one year.
It was a lot of fun, I had two touch sensitive pads, an ATTiny85 and some other stuff.
Made some badges out of it.
Made some videos out of things you could do with that.
It was neat.
More AVR things that were compatible with Minecraft.
I guess that's about it for my trash circuit boards.
Here's some synthesizer I made, little AVR on it, two audio outs...
USB's for power PS/2 for input PS/2 keyboard that is.
Worked, potted in silicone.
If you're curious how I pot my things in silicone you can click on that video.
This is a synthesizer I made, this is actually the one Dominic Cerquetti was playing.
It's got MIDI in, not used in that video.
It's got DMX out, not used in that video.
It's got this little synthesizer thing going on in the bottom, it's got this little synthesizer
thing going on in the bottom.
Got's an ATMega and some other junk going on in the top.
Got this thing here.
It's actually an ethernet enabled AVR.
It's the same one from my videos, actually it is running a minecraft server.
It's controlling the lights in my living room.
I guess I kind of abused the NeonFM RGB boards for their mosfets and decided to hook that
up to the white channel in my living rooom.
Here is a failed project of mine.
I tried turning an ATTiny85 into a switch mode power supply.
It was a lot of work and I never got it working well so I gave up.
So here is a few more things here I forgot about.
I took this big copper thing and soldered it to itself after cutting it in order to
make this T channel that slides into the keytar.
I have a video of it here lighting up.
Took a whole bunch of pretty powerful LEDs, strapped them to the copper with the silicone
heat sinks.
Strung them together.
Totally worked.
I don't think I'd do it this way anymore.
I think I'd use WS2812's and just put a BOATLOAD of them in there.
Another little project here.
I have these OLED displays and they're available from China pretty super cheap.
Decided to see if I could just get it to straight up work with an AVR, umm, just first of all
wanted to see if I could get it to work straight soldering to the board, the answer was yes.
It's easy as pie.
They talk to them very easily.
This cute little couple of these I made now, ATTiny85 boards... drive out 2812's light
things up randomly giving you timers giving you a clock.
Actually you can do full or I guess half duplex ethernet communications with them just an
extra two resistors or something else.
I made a bunch of these, this is just another revision of this.
I made a bunch of these, this is just another revision of it.
I love these tiny USB programmers...
Tiny ISPs, I made a bunch of different form factors.
This is one I didn't like very much.
Soldered on a female header.
Plug this into a board, like that there and you can program it.
Actually that's wrong.
There.
Now you can program it.
One of the problems with glass circuit boards is complete just failure.
Here these have the ribbon cable headers on them.
Here it fell forward... and when it fell, it smashed a hole through the back of the
board.
Let's see here if I can get this in focus.
Yeah, it's pretty catastrophic there.
I also have these paper pads here that I was playing with.
I watched a video on youtube of some kid playing a launchpad - a fake launch pad.
I wonder if I can do something like that super duper cheap, never cared and gave up on that
project.
Here's another glass circuit board that was a complete failure.
I actually damaged the battery somehow... then I lost the glass part of the front of
the pocket watch and I never found another pocket watch container that would fit it so
I gave up on that project.
Here is the AVR I used for my network and video at the same time on an AVR.
Umm, as far as I know this one still works except the wire fell off on the video.
Here's another successor for the optical DDR pads.
Like a lot of my boards, I'll build the boards but never write the firmware for it.
That's kinda lame.
Here I have a battery charger that I also never wrote the firmware for.
It's got all this nice stuff USB, was hoping to make a bunch of curves, but never got around
to making the firmware.
Or this here which is an ATTiny85.
It was supposed to be a general purpose anything clock, I was able to make frequencies anywhere
up to 60 MHz by xoring the two inverting outputs and using the deadtime generator.
While I was able to make 60 MHz with that ATTiny very easily.
Never wrote any firmware for it to be easily controlled.
Hope you guys liked this.
I had a lot of fun going back through many of my projects.
