So perfect for a lab-body

dapper hatch Aug 31, 2021, 9:35 PM

#

🙂

quartz wren Aug 31, 2021, 9:35 PM

#

Which is why I haven't replaced my glasses yet... Still (barely) legal to drive without them so no real need

delicate stream Aug 31, 2021, 9:36 PM

#

I quit glasses like 15 years ago

#

Never goin' back

quartz wren Aug 31, 2021, 9:36 PM

#

I like glasses because I can take them off easily when I get back to the lab

dapper hatch Aug 31, 2021, 9:36 PM

#

I need them to use my PC. Got away with looking at monitors for 40 years without needing them. So count myself lucky.

delicate stream Aug 31, 2021, 9:37 PM

#

I don't like glasses because I want to be able to wear sunglasses -- transitions were never strong enough

#

And prescription sunglasses are REALLY expensive

quartz wren Aug 31, 2021, 9:37 PM

#

Though my eyes do have 2 slightly different prescriptions so there's a bit of adjustment period after taking them off

dapper hatch Aug 31, 2021, 9:37 PM

#

I live in the UK. Sun? Whats that? 😄

delicate stream Aug 31, 2021, 9:37 PM

#

I also don't need to worry about breaking glasses if I don't wear them XD

dapper hatch Aug 31, 2021, 9:37 PM

#

Ha ha true

quartz wren Aug 31, 2021, 9:37 PM

#

I just get polycarbonate lenses haha

delicate stream Aug 31, 2021, 9:38 PM

#

I don't think they make glass lenses most of the time anymore... but the frames are what usually breaks

quartz wren Aug 31, 2021, 9:38 PM

#

Polycarb lenses will survive flying off my face mid-backflip and smacking into the concrete... I've tested... On accident

#

Though the frames do need repair after that...

delicate stream Aug 31, 2021, 9:39 PM

#

They will not survive getting smacked off your face by a flailing high tension line snapping and sending them into a concrete wall

quartz wren Aug 31, 2021, 9:40 PM

#

Oh yeah that'll destroy them for sure haha... Probably won't get major cracking but you will get clouding

delicate stream Aug 31, 2021, 9:41 PM

#

There was a big crack, but largely scratched to heck and back... Frames got shattered XD but my face was the bigger concern

quartz wren Aug 31, 2021, 9:41 PM

#

Yeah of course, the important question: were you damaged?

delicate stream Aug 31, 2021, 9:42 PM

#

Yes... Yes I was. But thankfully my eye was not. The line sliced into my cheek, hit my glasses, sheered off the nose pad, frames cut into my nose... but it was just bloody for a bit, healed up fine

#

Ohhhh, Lowe's takes PayPal!

quartz wren Aug 31, 2021, 9:44 PM

#

delicate stream Yes... Yes I was. But thankfully my eye was not. The line sliced into my cheek, ...

this is good to hear, eyes are hard to replace...

delicate stream Aug 31, 2021, 9:44 PM

#

Indeed

quartz wren Aug 31, 2021, 9:44 PM

#

and while a bit less hard to repair, generally do not get back to full working order (though can get close)

delicate stream Aug 31, 2021, 9:45 PM

#

Oh, can't use PayPal credit on Lowe's, boo

quartz wren Aug 31, 2021, 9:45 PM

#

uff

delicate stream Aug 31, 2021, 9:45 PM

#

Oh well, I don't need to go get my wallet, lol

quartz wren Aug 31, 2021, 9:46 PM

#

hey...very off topic, but does anyone here know how crypto-backed credit cards work? is it just like a normal credit card that gets the bill payed by crypto? or how does that work?

#

(asking because it seems most of the support for my game console will be crypto donations)

#

(and I need a way to easily convert that into components for prototyping)

delicate stream Aug 31, 2021, 9:47 PM

#

Credit card or debit card?

quartz wren Aug 31, 2021, 9:47 PM

#

I think all the ads I've seen mention credit

delicate stream Aug 31, 2021, 9:48 PM

#

Hmmm.... not sure... I've only really looked at debit cards

quartz wren Aug 31, 2021, 9:48 PM

#

well, I mean as long as I can do crypto-backed purchases of electronics components, then either works

#

in fact I'd prefer debit to credit

delicate stream Aug 31, 2021, 9:48 PM

#

Yeah, debit better

#

Adafruit takes crypto :D

quartz wren Aug 31, 2021, 9:49 PM

#

do you know if mouser does? I like adafruit's product selection but they don't have everything I need so I like to buy it all through mouser

#

(because they're partnered)

#

(so I can get adafruit products and bundle shipping)

delicate stream Aug 31, 2021, 9:51 PM

#

Not sure, haven't ordered from Mouser in a hot minute

#

Need to go get a shower and pick up a few gallons of mineral spirits... bbl!

quartz wren Aug 31, 2021, 9:57 PM

#

have fun!

#

and uh, also yeah going to need crypto-backed something for board manufacturing too...and I at least need to be able to get the 65C02 and the interface chips from elsewhere so I'll probably just look into crypto-backed debit and see what the options are.

#

ooh so I just took apart the crumbled remains of my dad's solder sucker and the piece that broke is something I can easily draw up in CAD and 3D print

#

😄 😄 😄

#

it's the plastic bit that holds the button assembly together so doesn't need to resist high temp

#

and it's a super simple part to draw up in openSCAD

#

and it gives me an excuse to pull out the calipers

#

if I can manage to find them in the clutter

#

ayyyy found 'em

jovial path Aug 31, 2021, 10:22 PM

It's is hard to not be stylish and I am not rich. Crazy world.

#

jovial path It's is hard to not be stylish and I am not rich. Crazy world.

And I never buy expensive things and still it is very hard to find not style.

quartz wren Aug 31, 2021, 10:59 PM

#

aaaand in an hour or so my dad's solder sucker should be repaired 😄 😄 😄

#

printing this piece as I type

#

only 7g of plastic according to cura

#

and that's at 98% cubic infill

#

(don't want it at 100% so it has a bit of give)

#

this may actually be the most useful thing I've ever printed

late fulcrum Aug 31, 2021, 11:11 PM

#

Coke bottles and Erlenmeyer flasks are popular for repurposing into CRT jugs.

#

quartz wren Aug 31, 2021, 11:13 PM

#

oh dang that's pretty

#

I was looking at wine bottles for it the other night

#

but saw the dimple in the bottom as a major obstacle unless I replace it with a more flat piece...

real falcon Aug 31, 2021, 11:17 PM

#

nice

quartz wren Aug 31, 2021, 11:18 PM

#

also I saw the Erlenmeyer flask idea on an Applied Science(?) video, but I don't have those...what I do have is lots of glass jars from various sources

late fulcrum Sep 1, 2021, 12:15 AM

#

May as well start with those. I have some of the blobby Pom bottles, one of those would make a cool looking CRT.

real falcon Sep 1, 2021, 12:18 AM

#

i wonder if its possible to flatten bottom

quartz wren Sep 1, 2021, 12:21 AM

#

for sure, just lay it on a flat piece of smooth metal and heat the plate to just above the glass transition temperature of the particular glass you're using and hold it there until it sags

#

requires precision though

#

and a looooot of time

#

at a precise temperature

#

of course, you could also just find bottles with a mostly flat bottom already

real falcon Sep 1, 2021, 12:22 AM

#

true

#

i dont plan to, just was wondering lol

quartz wren Sep 1, 2021, 12:23 AM

#

I mean, I may try it just out of curiosity once I have a glass working space but it's not something I have a high hope for doing very easily

hasty quarry Sep 1, 2021, 2:07 AM

#

Tell me if I understand e properly. An exponential function will have a property of growing at a rate of change that is proportional to itself. If you try to find the derivative of such a function you find that it just decays into base^x * (constant dependent on the base). The expression in there is a^dx - 1 / dx, which is a constant as dx approaches 0. The definition of e is the number whose constant happens to equal 1, so e^x is its own derivative

quartz wren Sep 1, 2021, 2:14 AM

#

yes, you rewrite it in terms of base e because the derivative of e^x=e^x. a more full explanation of the transformation into base e is given here https://www.youtube.com/watch?v=vZB_yys3GcU

YouTube

Expressing an Exponential in Base e

▶ Play video

hasty quarry Sep 1, 2021, 2:18 AM

#

I just derived e as the dx'th root of dx + 1, and plugged a really small number into dx

#

And it computed e

#

That is awesome

hasty quarry Sep 1, 2021, 2:22 AM

#

quartz wren yes, you rewrite it in terms of base e because the derivative of e^x=e^x. a more...

Thanks for this also. Expressing things in terms of e is really wonky to me still, I haven't formed intuition to it

#

I suppose it's because it brings out the constant of the base

stoic mesa Sep 1, 2021, 2:29 AM

#

instead of trying to understand what number e is, it is much better trying to understand what the function exp(x)=e^x is.
Here, the answer is simple: it is the unique function f(x) such that derivative (i.e. rate of change) is equal to the value f(x) and, in addition, f(0)=1.

After that, you just say that e = exp(1).

quartz wren Sep 1, 2021, 2:33 AM

#

@hasty quarry yeah, it's a bit of a wonky concept to me too. but yes, if you're exploring exponentiation generally you should form intuition for the exp function...something I have yet to do...

quartz wren Sep 1, 2021, 3:17 AM

#

@late fulcrum the board on this thing is terrible quality...definitely glad I decided to remake the controller entirely...

#

traces pulling just desoldering two lead components (mostly caps)

#

aaaand one of the potted transformers' leads pulled out even though I used a solder sucker

#

it's a wonder this thing was still able to generate a beam and scan

late fulcrum Sep 1, 2021, 3:42 AM

#

Probably a one-sided phenolic board

quartz wren Sep 1, 2021, 3:46 AM

#

indeed

#

I've got about half the components off, then I'm going to see if I can get a good enough scan to reverse the traces

#

I'm writing down component numbers and values as I remove them from the board

#

should be able to produce a decent schematic and break it up into the relevant sections for generating HV

#

if nothing else I can just map the traces with a multimeter in continuity mode

#

once I have removed all the components so I don't get false readings

late fulcrum Sep 1, 2021, 4:09 AM

#

I have some old TV documentation, if you have a make and model, I can see if I have a schematic.

quartz wren Sep 1, 2021, 4:15 AM

#

It's a drop in crt unit from some optometry equipment so I'm not sure I can get model, but it may be on the board

#

Will check when I get back inside

#

It doesn't look like it's too crazy complicated though

#

Should only take a few hours to reverse if we can't manage to pin down an official schematic

#

But what I am worried about is the transformer that pulled a pin... It was potted so getting a reading on inductance and whatnot isn't going to be accurate even if I shove the pin back into the hole it came out of...

#

Though it may be that the pin was not connected internally too but I have no way to check...

#

(without unpotting and potentially destroying the transformer)

late fulcrum Sep 1, 2021, 4:21 AM

#

Normally those have a few windings, and may be usable even if one winding loses a pin. The important one is the HV return: without it, you don't have useful HV. If you lose the primary, you can wind another primary onto the core and use that.

quartz wren Sep 1, 2021, 4:22 AM

#

Well, it wasn't the flyback that pulled a pin so we're clear on that one it was some other transformer with 2 leads on one side and 3 on the other

#

Center lead fell out

late fulcrum Sep 1, 2021, 4:23 AM

#

Could be a focus transformer or somesuch: probably not critical

#

quartz wren Sep 1, 2021, 4:23 AM

#

Noice!

#

So on the proto board should I coat the bottom where the flyback sits with shellac?

#

(after soldering in connections)

late fulcrum Sep 1, 2021, 4:25 AM

#

It's likely not necessary, but can't hurt. You can also use nail polish, insulating epoxy or good old fashioned corona dope.

#

Well, can't hurt other than it could make it tricky to modify in the future.

quartz wren Sep 1, 2021, 4:25 AM

#

Well I've got a crapton of orange shellac flakes so I'll use those haha

late fulcrum Sep 1, 2021, 4:26 AM

#

Wow, the real deal. I was looking for some of that just the other day.

quartz wren Sep 1, 2021, 4:26 AM

#

Yeah got it in a chemistry kit I inherited from my dad... I think he used it to bind pyrotechnics.

late fulcrum Sep 1, 2021, 4:27 AM

#

Yes, that is one popular use. I was looking at making up some vacuum tube base cement, which is mostly marble flour, but also includes shellac, rosin, phenolic resin, and malachite green (as a curing indicator)

quartz wren Sep 1, 2021, 4:28 AM

#

Huh... So does it cure using the oxygen in the malachite powder and change hues or something?

#

(partially using that oxygen*)

late fulcrum Sep 1, 2021, 4:29 AM

#

It's heat cured at 150°C. I just used an oven.

quartz wren Sep 1, 2021, 4:30 AM

#

Ah okay that makes more sense how the actual mechanism would work with that mixture

#

(for curing)

#

I need an oven that can hold a steady temp...

#

ogles at them on the internet being careful not to look at price

late fulcrum Sep 1, 2021, 4:31 AM

#

Mine seemed to do okay, but curing cement isn't a demanding or critical process.

quartz wren Sep 1, 2021, 4:32 AM

#

No but I want an oven capable of doing reflow

#

Lol

#

As well as melting copper (though of course not at the same time)

#

And if it can hold steady enough temp could work as a glass annealing chamber

late fulcrum Sep 1, 2021, 4:33 AM

#

I've been looking at the reflow controllers at http://www.whizoo.com/

quartz wren Sep 1, 2021, 4:34 AM

#

See if I'm just doing reflow I can make an oven for it...

#

Just get an old toaster oven and add temperature regulation

late fulcrum Sep 1, 2021, 4:35 AM

#

That's the use case for the Whizoo controllers: they give detailed instructions for upgrading a cheap toaster oven (additional heating element and insulation) and using their controller to get repeatable precision thermal profiles.

quartz wren Sep 1, 2021, 4:35 AM

#

That's not hard to do with one of the many 3D printer controllers in various states of function that I have

#

(went on a bit of a 3D printer kick back when I had some income)

#

But for real high temp stuff I need some better equipment

#

And I've found I'm pretty good at SMD by hand

#

Started learning how to do that a decade ago haha sure weird how time flies

late fulcrum Sep 1, 2021, 4:44 AM

#

SMD, huh?

quartz wren Sep 1, 2021, 4:44 AM

#

I'd say that's more "volume mount" than "surface mount"

late fulcrum Sep 1, 2021, 4:47 AM

#

Granted, I've done SMD, but I'm not really good at it.

quartz wren Sep 1, 2021, 4:48 AM

#

@late fulcrum not sure if this is helpful but this is all the identifying marks I can find, "K2" mark likely not relevant but included anyway

late fulcrum Sep 1, 2021, 4:49 AM

#

Yeah, that looks like a board revision

quartz wren Sep 1, 2021, 4:49 AM

#

https://i.imgur.com/MhJDHCi.jpg https://i.imgur.com/tOkQjft.jpg I'm okay at SMD

Imgur

late fulcrum Sep 1, 2021, 4:51 AM

#

Not bad.

quartz wren Sep 1, 2021, 4:51 AM

#

worked great once I cleared the bridge I found using a close up shot and cleaned off the flux that was acting as a pull resistor for some signal lines...

#

unfortunately it's like a 32GB chip or something like that and had to dump straight to file...not that I cared about the data on it anyway but still that means I need a 32GB file to flash it LOL

late fulcrum Sep 1, 2021, 4:53 AM

#

I am fond of those DIP adapter boards

quartz wren Sep 1, 2021, 4:53 AM

#

yeah, I have a bunch of the SOIC-14 to DIP adapters

#

got a bundle of them for christmas

#

this one came with a universal chip programmer that I got

late fulcrum Sep 1, 2021, 4:54 AM

#

I've been eyeing one of those to read off old PROMs and the like

quartz wren Sep 1, 2021, 4:54 AM

#

I got mine to do PLD development

#

very useful when you don't want to have a crapton of discrete logic for something you could fit into one chip

late fulcrum Sep 1, 2021, 4:55 AM

#

Yeah, I just wish there were better toolchains for them.

quartz wren Sep 1, 2021, 4:55 AM

#

F16V8B is quite a robust chip with a lot of capabilities and for $1/ea. it ain't a bad investment

late fulcrum Sep 1, 2021, 4:56 AM

#

I realize I can compute the fuse map manually, but I'd rather not.

quartz wren Sep 1, 2021, 4:56 AM

#

I wrote my own toolchain for wincupl so I didn't have to use their garbage editor and to convert the output that it gives into a file my programmer can use

#

now I just write in cupl in notepad++, hit f9, and flash the result

#

willing to share if anyone wants it

#

(though will need to be refactored a bit for configurability to a given system)

#

it's very handy to have an idea, draw it up, write out some (fairly compact) code, and have the chip you described

#

and actually I'll probably be using them as the interfacing circuitry between Pico and the 6502 in my game console

#

at least one, possibly 2

#

though I may design it in discrete logic to make the console available to be built by those without a chip programmer

#

idk

#

just depends on the cost comparison. if it's way cheaper to use one over the other it's the obvious choice, and if it ends up being PLDs I'll offer flashed ones for the cost of the chip to keep it affordable to everyone

#

since I know a $200 chip programmer is out of reach of a lot of people just to flash a few chips for making a game console

#

and I know this because I was resigned to never having one and then a miracle struck and I earned enough money to get it right when I was needing it

#

or rather, not never having one, just resigned to having to build it myself

#

but luckily that was not the case and here I am, able to make fairly complex logic circuitry sit in a single chip without much added expense above the initial investment

#

and since I invested time developing the toolchain I needed, I don't have to waste time trying to get the file into a flashable form

#

when I started, I was getting output files that would attempt to flash, but fail on verification and then not operate how I wanted

#

and I was super stumped on why it wasn't working

#

so I read a file out from a blanked chip to look at the format differences and wouldn't you know it, there were a few

#

so I wrote a little converter script in python that would convert from the compiler output to the programmer's input format

#

but that was tedious because I kept having to drop a file into its folder, rename it to "input.jed" and then run the script

#

so I decided to automate the whole process with a single button press

#

and while it isn't the most elegant implementation it works without issues

#

though I'm really not sure if it works for any chip but F16V8B

#

because that's the ones I'm using lol

#

this is the entirety of the memory address preliminary decoder system I was developing for the pure 6502-based machine

opted for more verbose

#

there may be some inversion errors on this version but the fix for those is prepending "!" to the thing that needs inversion

#

(or removing ones that have them if it's being inverted and doesn't need to be)

#

but the base structure is here for the whole chip

#

reason I haven't fixed the errors is I moved on to another project lol

#

but I will be revisiting this once I have more mental and emotional energy to devote to tedious wiring

#

well, talking about this project and looking at the cupl code...well...let's just say it has inspired me to put a bit more work in on this one

#

I've now assembled a protoboard array for this as well 😄

#

it has 6 7cm x 9cm protoboards arranged 2x on the 9cm axis and 3x on the 7cm axis, so nearly square

#

should be plenty of space for a 6507-based computer with banked memory

#

upon further inspection of El Pico Yolo, the razor blade didn't go between the fiberglass, but instead shaved off some of the ground plane

#

but it looks like all the IO is still connected

quartz wren Sep 1, 2021, 5:53 AM

#

should be able to refill on medicine tomorrow, which means that I'll be able to focus on something

#

today was just all over the place, mania with nothing to ground me, but I did manage to fix my dad's solder sucker (and bounce around between like 10 other things doing almost nothing on each)

#

rearranged to 2x3 on inverse axes, so that it fits better in an ammo can...definitely want to put this thing into one of those

#

hmmmmm....I wonder how a pickle jar would work as a CRT jug

#

it would give a pretty decent viewing area

#

actually I think I want to do a custom case for this thing that's 3D printed...

but I did find like the perfect LCD panel for mounting to the bottom of one of these cans...

#

and it has each of its control wires broken out individually instead of in a ribbon 😄

#

maybe I'll just make a 6502-based laptop idk

#

Look how perfect it is

yeah, I think I'm going to turn the 6507 project into a laptop

#

tardy badger But Arduino defs are hard

not that hard if you start with existing board definitions and modify them as needed

#

much more difficult was deciding what peripheral to enable on what pin - but once you made that decision, writing the actual board def file is easy

tardy badger Sep 1, 2021, 10:43 PM

#

I did that before and it didn’t go so well lol.. It was for a atmega328p board

#

Thankfully Bread can use the Arduino Mbed OS RP2040 boards board def

quartz wren Sep 2, 2021, 12:08 AM

#

Ah

#

Well the idea is simple, pull the inputs low through reverse bias diodes and pull the common anode high with a resistor that's the number of inputs multiplied by the pull down resistance of each input

#

The opposite works for OR, to pass each input through a forward bias diode, then pull the output down

After admiring (and buying) the discrete implementations of the 555 timer and 741 op-amp, I wondered about discrete implementations of logic gates and did a bunch of research on how, learning how to build oddball multi-emitter transistors out of ordinary ones, and realizing there was a commercially available PCB that makes for a good-looking implementation.

quartz wren Sep 2, 2021, 12:23 AM

#

Experimentation is good for learning though 😉

late fulcrum Sep 2, 2021, 12:24 AM

#

I came up with this implementation of a single 7486 style XOR gate

quartz wren Sep 2, 2021, 12:24 AM

#

But yeah I think I can get away with 3 or fewer chips for the entirety of the select logic on this address bus

#

With no PLDs

#

Or 1 with a PLD

#

Lel

#

Actually... I might have enough extra inputs to stick the chip select logic all inside of one

#

runs the numbers

late fulcrum Sep 2, 2021, 12:25 AM

#

I had read that you could build any logic circuit out of NAND gates, so I figured that's what was in the chips themselves: forests of NAND gates. But I was wrong. It turns out that a 7430 8-input NAND gate chip contains a total of 4 transistors.

quartz wren Sep 2, 2021, 12:26 AM

You can build any logic gate out of inverters diodes and resistors

late fulcrum Sep 2, 2021, 12:26 AM

#

I'm working on a design for a 3-chip computer: 1802 CPU, FRAM for both RAM and ROM, and a CPLD implementing a few gates for address switching, a counter, latch, and lookup table that along with the DMA capabilities of the CPU and a few resistors, provides a video output.

quartz wren Sep 2, 2021, 12:27 AM

#

I've proven it in diagrams and truth tables hehe

#

And implemented a few to check my work

#

Could re-derive it but uh... No clue where the original notebook went

#

(I go through notebooks like Mr. Kool goes through walls)

late fulcrum Sep 2, 2021, 12:29 AM

#

Yeah, that's RTL/DTL logic, the same stuff as the Apollo guidance computer (which was built out of nothing but dual 3-input NOR gate chips for logic)

quartz wren Sep 2, 2021, 12:30 AM

#

Yeah and that can be done with 3 diodes, 5 resistors, and one transistor if my quick mental design serves

#

(per NOR gate)

late fulcrum Sep 2, 2021, 12:31 AM

#

The chip used in the AGC used 3 transistors, but yeah, pretty simple.

quartz wren Sep 2, 2021, 12:31 AM

A bit different than I'd have done it but then again I'm not a qualified anything

#

(if pieces of paper to denote "qualifications" serve to inform)

late fulcrum Sep 2, 2021, 12:32 AM

The problem with the diode/resistor approach is fan-in/fan-out and noise considerations

quartz wren Sep 2, 2021, 12:32 AM

late fulcrum Sep 2, 2021, 1:39 AM

#

I grabbed a data book to get a picture of an LS TTL gate built using diodes to combine inputs

quartz wren Sep 2, 2021, 1:49 AM

#

Nifty!

#

So it may still be a good idea to buffer each of these outputs through a transistor at least to limit possible current differences when different numbers of inputs are active right?

#

If so, no reason not to just do inversion using a transistor too so that I don't have to waste 4 inverters on a chip... (only need one or 2 inverters depending on design)

#

(am drawing out entire memory selection design at the moment using minimal chips)

#

I think I have something nice and minimal... Does not include address lines that go directly to chips

#

#

Hmm something is wrong here...

#

I need to either build some test circuitry or find a way to simulate this... Sure hope logisim has diodes I've never needed them before

#

(though I have so many scrap diodes it would be silly to simulate when I can test on the actual diodes I'll be using...)

#

To the breadboards!

#

(then once I have something that does what I want, set it on the board)

#

Actually just looking over this again I can see the select line on the low bit 2-4 decoder for the registers is probably going to be inverse... Also I think I can eliminate a bit of circuitry if I just program Pico to detect whichever signal is easiest to implement in the circuitry as far as active state

#

Since the rest of it is simple

#

May as well simplify further if it's within the configurability specs of the system

#

Oh actually I think the only thing wrong in this drawing is where I have the second inverter...

#

I think it should be before the junction to the second decoder but that depends on active state of the device.

#

(whether decoder's enable is active high or active low)

#

(but I'm guessing active low, as I'm pretty sure that's what I've got, with active low outputs, which lines up great with the standard active low of a lot of memory chips)

#

I guess 9 diodes, 2 chips, 2 transistors, and a few resistors ain't a huge deal

#

Especially since I would still have all of that but the transistors and minus one chip if I used a PLD

#

So not much gain to just implementing it in discrete logic if it enables everything I need using that little hardware

#

Oh no it would still use 2 chips, would just replace the inversion logic with internals on the PLD

#

So just minus the transistors

#

I mean I guess I could also pack the whole thing on a PLD with just pulled, commoned diodes on inputs with inverted signals normalised inside the PLD...

#

And it would enable future expansion

#

Thoughts?

No idea XD

quartz wren Sep 2, 2021, 1:06 PM

#

Yeah that's why it's the end goal for now on custom

delicate stream Sep 2, 2021, 1:07 PM

#

Modern boards need teams and manufacturing resources... And things like memory channels and PCIe traces need to be basically perfect. Plus you can't get chipsets

quartz wren Sep 2, 2021, 1:08 PM

#

Yeah anything above about 200MHz I don't want to touch

#

And by that point it will be a custom CPU on an FPGA

delicate stream Sep 2, 2021, 1:10 PM

#

I wanted to build a custom PCIe card and gave up after reading the PCIe spec papers for 3 hours and only knowing a tiny tiny fraction of the handshake for the protocol XD

quartz wren Sep 2, 2021, 1:10 PM

#

Did you look at the timing diagrams?

#

(only half joking)

#

If you did, I feel sorry for your brain... If not, might actually be helpful

#

At least if it isn't one of those insanely compressed ones that tries to cram all of the timings for everything into a single diagram then all bets are of barring a bout of mania

delicate stream Sep 2, 2021, 1:13 PM

#

quartz wren Did you look at the timing diagrams?

Yes XD so complex

quartz wren Sep 2, 2021, 1:13 PM

#

Because unless you're used to looking at those compressed timing diagrams, you basically have to draw your own diagrams to extract each scenario you care about

#

(until you gain an intuition for how they represent the combination which can change from designer to designer)

I want to make a pcie card that implements a 65C02 and interfacing hardware to share PC memory so you can do the same thing my game console will be capable of but drawn to a window on your PC

delicate stream Sep 2, 2021, 1:18 PM

#

I'mma build ISA cards... Eventually...

quartz wren Sep 2, 2021, 1:18 PM

#

Native 6502 code-running capability remappable to any of the systems the 6502 was used in, assuming the rest of the system has been emulated and the appropriate system ROMs are loaded

#

An "emulator" that can match timing spec of the original system within the tolerances of the original crystal for high score validity

#

But can be interfaced to any gaming hardware you can use as HID

#

May still use the Pico or the bare RP2040 chip to do the DMA control and buffering and timing logic, since it barely adds to the cost and can act as mediator between two very different speed devices as well as offload some o the processing needs from the PC

#

(so for instance may just make a version of my game console that drops into PCI-e and draws its frame buffer straight into PC memory but still has all my console's capabilities)

#

But with a virtual display and IO routed through a window on your PC

delicate stream Sep 2, 2021, 1:24 PM

Pico is magic

quartz wren Sep 2, 2021, 1:24 PM

#

Indeed. I'm actually using El Pico Yolo for the 6507 laptop

#

Because Yolo

#

And because if it breaks who gives

#

I built an ISA card in college, long time ago 😄

quartz wren Sep 2, 2021, 1:32 PM

#

I disassembled an Isa card a couple years back... Where do you think I got a good amount of my scrap chips hahahahaha

#

It was a video card in discrete logic so very densely packed

polar bloom Sep 2, 2021, 1:33 PM

#

Yeah those old cards have lots of chips on them.

quartz wren Sep 2, 2021, 1:34 PM

#

Saw it in my dad's scrap and I'm like "sooooo what are you going to do with all those chips?" he's like "sell them for scrap" yoink "here's a couple bucks to cover what you would have gotten for scrap"

#

And now I just have a bunch of tubes of IC's I have no clue the status of and don't care if I break them

#

But as I use each one I build a little test circuit for them to make sure they at least pull the levels correctly to light LEDs through resistors

#

Once I have my oscilloscope/signal generator/logic analyser built I can just have that be one of the functions and give me actual traces so I can make sure it's in spec electrically too

#

In fact I don't see why I can't make one of the i/o locations switch between several analog channels per each of the native 3 in software so it can analyse all the pin characteristics of logic chips without having to do some kind of selecting by hand...

#

Then you use digital output channels as input to the chip's pins (with a database of part numbers and their associated IO) and cycle through three outputs at a time gathering analog traces through the various state changes

#

To do proper electrical analysis of logic chips

Part of it is personal preference, part of it is people have different mental models. For some folks, it's easy to get from "I want a hole in this object" to "translate and rotate a cylinder of this size and subtract it from this"; for other people that is a difficult process.

#

I am toying with the notion of making a generic chip characterizer (real goal is to determine if some rare 6530 chips are operational)

True... I wonder if any front-end interfaces exist for point and click OpenSCAD modeling that auto generates code...

#

If not might be fun to develop

#

And I could make it generate clean code using variable names set by the user (as parameters in the system that can be tweaked kind of like how solid works(?) does it)

#

And separate the curly braces onto their own line so one-line comments can be used to toggle modifiers

#

So you can build up a boolean cutting object in positive, then toggle it on as the cutting object

#

For example

#

Or turn off a for loop that generates a bunch of objects so you can look at and modify just one, subsequently turning it back on

#

All with addition and removal of just a couple slashes if you structure the code right

#

And you could easily make it modifyable so that users can add custom primitives using code they wrote or generated for future use via menus and hot keys

But I still think it is an amazing idea.

quartz wren Sep 2, 2021, 2:55 PM

#

yeah, I get by fine with a mouse and sometimes a borrowed drawing pad (and for CAD, mostly a keyboard, just use mouse to pan and tilt the object view)

#

I actually still do a lot of my initial designs on paper so I can get a general layout, then figure out what measurements I need to take to do a proper drawing

#

but for artistic stuff I just go for it

#

the request from my friend was a bone crown kind of like roan's from the 100

#

for reference

#

I think I did okay

#

given the printing constraints

#

although on some points it does almost look like muscle rather than bone lel

#

eh, it was 3 days of mania fueled modeling using that particular tool in blender for the first time...

#

turned out far better than I ever expected it to

#

in fact, I even told the person "I may not be able to do this, but I'll give it a shot"

That actually looks pretty easy to do

#

Though I basically grew up on trampolines so that probably helps...

yeah...thinking about it...definitely adding my FPGA board to my laptop design

#

because why not

#

it fits

It really would. I bet I’d hit my head on something and fall off. Cool that you have those skills though!

dusty citrus 'eye eye see'

You're the only person I've known to say it that way XD it's not even written as IIC often

#

Is there a pronunciation guide in there? Lol

dusty citrus Sep 3, 2021, 12:26 PM

#

I learned it in my head from printed text.

#

iic on the page; mind says 'eye eye see'.

#

there was never a spoken conversation conveying this information when I was introduced to it.

delicate stream Sep 3, 2021, 12:28 PM

#

Same XD but it was always written I²C or I2C in what I read

#

I think I normally say "eye two see"

vagrant sonnet Sep 3, 2021, 1:01 PM

#

same

#

maybe we're not mathy enough

late fulcrum Sep 3, 2021, 1:02 PM

Not "I eye see" ?

Airplane joke

Before "madbodger" , I used to use "uoo" because it was easy to type and hard to pronounce

Cost optimization

delicate stream Sep 3, 2021, 1:32 PM

Taking a year to prep a shipment seems like the opposite of optimization, the longer it gets, the more I think of cancelling and buying elsewhere

I personal²y don't²hink that spel²ing words with double let²ers as noncom²utative polynomials is neces²ary.

("I personal squaredy don-squared hink spellsquareding words with double letsquareders as noncomsquared-utative polynomials is necessquaredary.")

delicate stream Sep 3, 2021, 2:24 PM

#

Lol. I2C does look cool... but it really only seems necessary for like 4+ letter repeats

#

Even IEEE isn't that bad

wooden schooner Sep 3, 2021, 2:24 PM

Interestingly people say "I triple E"

#

And you can even start a word with it: "triple A S"

I figured out how to write while x > 1: ... without using while: ```python
for _ in itertools.takewhile(lambda _: x>1, itertools.count()):

wooden schooner Sep 3, 2021, 2:52 PM

#

🤣

#

Both of those new checks are horrible

delicate stream Sep 3, 2021, 2:52 PM

o.o

wooden schooner Sep 3, 2021, 2:53 PM

#

Python ternary expressions are... even worse than C ternary expressions

sick adder Sep 3, 2021, 2:56 PM

#

at least the checks are not enabled by default. I just .. was interested in the challenge of replacing while

wooden schooner Sep 3, 2021, 2:57 PM

You gotta use itertools.takefor_in though
