currently trying to make a flip-dot display (think https://theartistbreakfast.com/works/spectral-flashbacks-ser...) but with some kind of radiation detector behind each pixel that will flip the dot when something passes through

i made a small 3x3 proof of concept using more expensive geiger tubes, and their really long 'z-axis' lengths made 'traces' happen very often, like a persistent cloud chamber

trying to find a reliable semiconductor (read:cheaper) method i can scale to an arbitrary number of pixels, but something seems to happen in between the bench and the wall :(


How many pixels would you aim for?

I have considered

* scanning a linear array of BPW34 photodiodes, in a similar spirit to a scanner to cover a plane, each photodiode going to its own "MCA circuit" (TIA->cheap audio codec like those from Everest Semi). Either direct measurement of generated charge pulses or covering the photodiode with phosphor on aluminum foil or so

* cloud or bubble chamber (cloud chamber is less dense and will generate fewer events, so probably bubble chamber): instead of needing a large 2D or 1D array of parallel circuits, we image and track generated charged particles and use the trajectory starting end (less curved) to determine the source direction!

* consider X-ray crystallography, an incoming straight beam can diffract in many directions on a monocrystal. rotating say a silicon wafer, and measuring the incoming photon energies with one or more photodiode/MCA circuits we can assign a source likelihood distribution by keeping track of the orientation of the monocrystal. akin to sparse sampling but instead of masks its diffraction patterns.

If you have better ideas or variations in mind, let me know!

multi-generational households

The reality of most multi-generational households is that the wife is eventually coerced into becoming an unpaid caregiver for elderly parents (who often constantly criticize how the household is managed). This sort of "worked" in traditional societies when women didn't have other options but when they're educated and have their own careers it usually doesn't seem like such an attractive choice anymore.

I'm not opposed to multi-generational households and I have friends who have made it work well. Let's just not assume that it can be a scalable solution.


It was never an attractive choice- people simply did not have options. In my country it was not until the 1950s that retirement homes were invented and the elderly finally got their social security (remember pensions did not exist).

I would rather have access to a suicide pod.

careful dont let private equity hear you say that

I'm more worried about Catholics and other people that want to enforce their religion on others preventing access to suicide pods.

for incredibly simple parts that i can describe using measurements, i've had a lot of fun pointing a high-power ai at openscad and letting it iterate through making the design for me

it's still tough to turn it into something i can then keep fiddling with in freecad though

put on "tron: ares" in the background to fully appreciate the model designing something that will be 3d-printed :)


I haven't tried it, but FreeCAD has scripting

https://wiki.freecad.org/Python_scripting_tutorial

Edit: Your website is quite confusing. Took me awhile...


ty for 'tearing through' ;)

I had to... rip it apart to figure out what it all meant! ;)

You can get even more vague and just generally describe the design of something, making sure it leaves exact measurements to parameters, and end up with something usable. ("Make me an openSCAD file for an pointed star with curved points and an inward taper. The number of points, thickness, and angle of taper should be configurable")

For a lot of stuff, you might have better luck getting it to generate something like cadquery

Did you try modelrift.com ? Its openscad + ai but way more convenient to preview results in realtime and iterate via annotated screenshots

vinyls have secret songs on them ;)

yea all of modern semiconductors were built on a guy going "wouldnt it be cool if i could write using metal instead of ink"

i try to keep tabs on restaurants opening around me, and if one has something interesting, i text pretty much every friend i have if they want to check it out with me

only a few respond each time, and only about half the time one or two can make it out, but over time eventually all of them do


you fill the 3 liter bottle up to the top, and pour the contents into the 5 liter bottle

then you fill 3 liter bottle again, and pour the contents into the 5 liter bottle until the 5 liter one is full

empty the 5 liter bottle, and pour the 1 liter in the 3 liter bottle into the 5 liter bottle

fill the 3 liter bottle again and pour that into the 1 liter already in the 5 liter bottle to get 4 liters of water


Then you bring the fox back, take the hen across the river, ...


I'm so glad that style of inerview was dying out right when I graduated. And I love puzzles. But I don't need wannabe IQ tests for a job that expects me to work in legacy code and coordinae with other engineers.
