you guys wanna see some really fuckin janky electronic hack?



no idea how it survived the bumpy 50km ride home & still worked for months .. replaced it but now somethin else is hosed because of (less janky) hacks just expiring i guess

One thing that you could do would be to pull out the tubes ONE AT A TIME, look them up for pinout and check to make sure you have:

-continuity between the heater pins
-no continuity between either heater pin and the cathode
-no continuity between the cathode, any grids, and the plate


you're probably going to find dried out caps, too, but stage 1 is to test tubes

please be very careful the guts of that box really could put you in the ground
one hand in your pocket at all times* and move slowly and carefully

*this is so that you don't create a path for HV across your chest with both arms. better it go in one arm and down your body to ground

I want to make my own 8 bit mini. I went on a binge and bought a 6502 knock off. I also bought 32kb of ram, and 16kb of rom that should be bus compatible. I have something I think will work for a keyboard controller. What I don't know how to do is provide video out. I've thought about just doing a serial interface at first, but I'd rather just start with video out. I can't find anything that will really work. Monochrome is fine. Anyone have any suggestions?

Shipping and handling was more expensive than the parts. $10 for all the chips together. I think the processor was $6. I had everything else I need.

Guess it wouldn't be that big of an investment to purchase a z80.

Who owns the rights to the 6502 now or did MOS survive the death of Commodore? It's probably the most influential microprocessor ever made.

The 6502 singlehandedly took microcomputing out of the realm of expensive hobbyist toys and into the average dining room. If you don't recognize the effect that had, you aren't qualified to have an opinion.

not really, the computers it was used in did that sure, but that's not really down to the 6502 itself is it. home adoption of microcomputers was driven by to falling purchase prices and available software libraries, not the cpu those computer happened to contain

the 6502 isn't what made the 2600, c64, or NES a success

The 6502 was one-sixth the price of competing CPUs and you're too loving stupid to realize how that was influential even though you cite falling prices as one of the reasons for widespread microcomputer adoption. lmao

please enlighten us what was "influential" about the 6502. not why it was popular, because popular != influential. what specifically about the processor itself was influential? because it wasn't the bus design, or the instruction set, or the programming model, or the hardware design, or the production method, or anything like that.

You are an autism victim if you don't understand how popular = influential. The 6502 was cheap enough to put a computer in every house that wanted one. A lot of people cut their teeth on programming with them. More users meant a larger and more diverse software library.

Were it not for MOS pushing prices into the basement, the computing landscape would look very different now.

What hosed up idiot world do you live in where popular products are not influential? Do you live in a world where everything is judged solely on technical merit?

this whole discussion started because a guy wants to build his own computer, now in 2014, not in 1977. and your whole argument is "the 6502 was in a popular product, therefore it is good, therefore the guy building his own computer today should choose it over the cheaper/better alternatives."

It's okay to admit you're wrong, you know.

i dunno. i think building one can be a good learning exercise. the big plus point to 8-bit stuff is that all the chips are available in DIP packages so it's easy to hand solder everything, and adding memory and peripheral chips is really simple. even just the step up to 16-bit means everything is surface mounted and the bus designs don't really lend themselves to just slapping on more chips and everything just working. plus 8-bit cpus are slow enough that you don't have to worry about all the spergy stuff like track lengths and clock phasing

Walmart has computers if you need one that badly.

Sagebrush posted:

prepare for :words:

basicaly there are two different fundamental ways of storing 3d data (not counting weird stuff like voxels): polygonal models and NURBS surface model. polygonal models are what you think, lots of flat surfaces that you move around by pushing and pulling vertices and with enough of them you can approximate a curved shape. polys are super lightweight and fast and they're easy to work with because you literally just grab a vertex and move it. video games and many movies use high res polys because of this (and because they don't care if your round machine gun barrel is actually a 12-sided prism)

NURBS modeling is a way of mathematically describing the curvature of a surface with a continuous polynomial equation. once you set the parameters for that equation, you can sample it at any point and get the exact value for the surface location, so a NURBS can be sampled at arbitrarily high resolution. it's the only way to 100% accurately record a curved surface like a sphere or the line of a car body in a computer and so is also how all modeling for engineering and design is done.

disadvantage of nurbs is that it's harder for people to wrap their heads around, because you aren't directly adjusting the surface shape but only controlling the equations that define the surface, so it can be harder to grasp initially. but it's the way to go if you want quality engineering models.

then within nurbs there are two main modeling paradigms: solid modeling and surface modeling. fundamentally they make the same type and quality of model but they're different mindsets. in solid modeling you act like you're starting with a block of wood and carving pieces away or gluing more pieces on until you get teh shape you want. in surface modeling you act like you're building a wire cage for the model and then stretching fabric or paper along the outside to get teh shape. ultimately surface modeling is the most open and flexible but also the most difficult to understand.

if u want a programming analogy, poly modeling is like python or something (used in industry but not for the really serious life-threatening stuff), solid modeling is like C++ (the bread and butter of 90% of the good engineering you see out there) and surface modeling is like assembly (total control over every aspect of your product at the expense of increased complexity)

rhino is primarily a surface modeler with the option to do solids and some polygon editing and conversion. solidworks is a solid modeler with a not-very-good surface modeler patched in and no helpful handling of polygon data. art apps like 3ds, maya, cinema 4d are going to be primarily polygon modelers with some basic nurbs surfacing tools thrown in and no solid-modeling paradigm.

so surface or solid modeling is where you wanna go for the highest quality and accuracy if you're making a model for manufacturing. HOWEVER there is one more aspect: the resolution of the 3d printer. most printers these days don't even approach the resolution of a quality cnc'd injection mold, so you can totally get away with a low res polygon model in most cases. in fact 3d printers take only poly models as inputs (stl file), but if you start with a nurbs you can render it out at low or high resolution as is appropriate for your printer and model scale. w/ polygons you're stuck at whatever number of polys you have.

essentially if what you're printing is warhammer figures or something and you don't care to go further then any 3d modeling program will do you. if you wanna start making useful mechanical parts then you want a real nurbs cad program most definitely.

There is only one fundamental way to store your posts, in the trash. lol
