Restoring a Cheap Fume Hood


Semiconductor fabrication is complicated requiring nasty chemicals for everything from dopants to etchants. Working with such chemicals at home is dangerous and after releasing hydrochloride acid fumes into his lab, [ProjectsInFlight] decided the time was right to get one for a mere $200.

I can hear the readers down in the comments already saying, “why not just make one?” But a properly engineered fume hood provides laminar flow which absolutely ensures no leakage of fumes out of the hood. However, such proper engineering comes with an impressive price tag, so the used market was the only choice. This is less dangerous then it sounds as companies are required by both OSHA and the EPA to clean their fume hoods before removal, so no chemical residue should remain after purchase.

After inspecting a more expensive unit, [ProjectsInFlight] bought a smaller unit destined for the scrap heap. Very little work was required to get it actually working. Some LED lighting and cleaning got the machine in a workable condition. A neatly welded table was built for the hood with an acrylic painted plywood work surface. While professional fume hoods use solid epoxy work tops, these are expensive, and polyurethane should be fine. A high flow rate fan neatly tied up the fume hood restoration.

However, merely having a fume hood is not enough for some. Therefore, [ProjectsInFlight] turned to his lathe to create a lab rack. This device is a kind of ladder looking thing which provides numerous mounting points for clamps making chemistry easier and safer. Some careful and somewhat sketchy machining resulted in a professional looking lab rack for a fraction of the professional price tag. The whole project was neatly tied up with machined chilled water and vacuum inlet ports.

This is not the first time [ProjectsInFlight] has made the pages of Hackaday. Make sure to check out the fume hood’s inspiration in this gold nonparticipant fabrication hack!

President Trump is trying to send a lot of messages lately.

But the message that comes through the loudest is,
please please please don't look at the Epstein Files

Whatever Mr. Trump is ashamed of, it's more sketchy than statutory rape.

No government has ever been “publicly owned and operated.”

If that were true, I’d be getting quarterly dividends instead of tax bills.

in reply to Chris Trottier

If it was selling something to someone outside, perhaps.
As it is you are probably getting capital gains (it may be unevenly distributed). services some visible, some less so, and some insurance.

For which you make a contribution to the expenses of the whole.

Perhaps the public are not as good at running what they own as they might be, nor at the oversight of the operation?

in reply to A man is retired

@Photo55 Governments sell things to entities outside the nation-state all the time. Often quite successfully too. And in fact, governments have a competitive advantage over other entities because they can go to war and put people in prison.

Bien merecido para don Luis Muñoz... Su concierto el año pasado en Casa Rojas de Barrio Escalante es de los conciertos que más he disfrutado y sentido en estos últimos años/meses. Música que trasciende ❤️ 🙏🏽 🎶 crhoy.com/pelin-ganador-de-pre… #CostaRica

Afortunadamente la UNED grabó hace un par de años un concierto completo de Luis Muñoz acá en #CostaRica con los músicos que normalmente toca en US.... un enorme gusto escucharlo: youtu.be/Pr6RQPr_KGY?si=04R_Bh…

In a dangerous escalation in nominative determinism, several nations have acted to rename the bureaucracies governing their militaries “the Department of Victory”, “the Department of Unassailable Triumphs”, and “the Department of World Conquest Preordained by Manifest Destiny”.

They are amazing. Like that maple that uses wind for both pollen and seed dispersal. And the fruit trees that use insects for pollen dispersal and different animals for seed dispersal later in the year. The diversity of shapes and strategies!

We tell ours apart mostly by behavior. Blanche loves to run, climb, chase a lure on a stick, leap in the air .and just generally wants to be Simone Biles when she grows up. All Stella ever wants to do is snuggle and purr. Predictably, she's gotten a little heavier. Blanche has a little white spot on her chest but we can only see it when she rolls on her back. Sometimes we wish we had tuxedo cats so we could tell the apart when they're snuggling each other, but on the whole, life is better with *any* two cats than it is with one. They keep each other amused. Us, too.

And they're good for our health. It's a scientifically proven fact that looking at cuteness lowers blood pressure. We laugh a lot, too. One cat good, two cats better.

Yay for audio plugins under Wayland.

Non-embedded type for now, but one step at a time we will get there.

Also, today I answered a question I had for a long time...
If an X11 host running under XWayland calls Wayland-native APIs manually, would it be able to load Wayland-UI based plugins?
The answer is yes - Carla running under Qt xcb "platform" can still show Wayland UIs.

The reverse is also true (Qt wayland "platform" with X11 UIs through XWayland)

Future is bright 🌄

So the latest Republican Narrative will be that if there is any evidence of Trump being associated with Jeffery Epstein (eg on the client list) it is because he was there on a mission from the FBI - a secret informant for them. Now that is quite believable, isn't it?
