Test Equipment Anonymous (TEA) group therapy thread

[Kosmic]

thought of some social warrior stuff which I will submit to our company as an idea for their making more health initiative.

take a COTS aluminium box.

take a finished starter/socket for a UV-C lamp

and the UV-C lamp

which will give me 3W of UV-C at a distance of 1m from the center of the lamp

Utilize UV resistant bonding tape (3M VHB) to attach this to the lid of the box and

Cabling is not too expensive.

An inverter running off a lead-acid battery can easily be added. You can also put in a standard grill shelf rack https://www.ebay.co.uk/itm/BBQ-Adjustable-Grill-Shelf-Rack-Extendable-Screw-Fix-Arms-Barbecue-Grid/191404896648?hash=item2c909ef188:g:5TUAAOSwabhUXMjN

to lift the stuff to be irradiated and make sure the UV gets to it from all sides.

To make sure the dosage is sufficient, irradiation time should be no less than 10 minutes, preferable twice the amount.

It would be possible to swap out the lamp for a higher dosage lamp, but those would draw more power.

What do you think ?

Did I overlook something critical ?

Even more ghetto, a simple carboard box with aluminium paper inside 



I used this setup to retrobright parts. Now I can sterilise my mail

Man I think the mail system is seriously clogged over here. Have been waiting for my usb connectors from China for 2 months now and they are nowhere to be seen 

[Saskia]

I know. The idea was to be able to have something somewhat sturdy that would survive but still be easy to produce and halfway safe. That can be stowed away safely, airlifted, mailed, etc.

Our company has some health initiatives world wide. Now, given the current crisis, our colleagues in india, in the philippines, etc are suffering. This would give them the opportunity to build something sturdy which is still easy to obtain and does not cost a fortune. my first idea was to improvise using an easy to get G23 lamp and a cardboard box. But, for logistics, durability and sturdiness I thought this setup might be better suited.

I think it's everywhere involving international. The HP probes for AVG didn't kick back a 2nd time from US Customs but who knows where they are at now.

I resemble that remark! Beware, what we lack in youth we make up for in subterfuge. 

I've whiled away my breakfast-time this AM noodling around this fellow's yoobToob: https://www.youtube.com/channel/UCMuCEiwVy_jvFmboAEYGwjg



His hobby is creating animation to go along with the original BBC Radio show of HHGttG; rather good actually and very faithful to Adams' written works. Unfortunately, the Beeb has been forcing places like YT to take down his works and Ep 1 Pt 1 is no longer up. However you CAN, if you care to, find most of it on his channel in bits & bobs.

Somehow, this fellow's whole debacle of "Fair Use" vs the interests of the corporate megalopoly etc. feels very Adams-esque in its own right...

Queueing for supermarket here again today. The locusts have eaten all the good stuff again 

I presume by that you mean the teenaged locusts you keep as house pets rather than the locusts that cleaned the supermarkets out.

I was joking with my box. I prefer your idea. Never seen aluminum box like that over here though.

You could add a timer to stop the lamp automatically ? also maybe a red led that let you know the lamp is active ?

[Cerebus]

Did I overlook something critical ?

Interlock switch for the lid? (Commenting as I'm catching up, so ignore me if someone else has said this in the interim.)

[BU508A]

What do you think ?

Did I overlook something critical ?

I would add a safety switch. As soon, as the box gets opened, the lamp should be switched off immediatly. I'd realize this with two reed contacts and a magnet, probably at two opposite positions.

[med6753]

Gee, with everyone being sheltered in place and bored out of their skulls this thread has gone nuclear. 

[Saskia]

an interlock switch is an excellent idea. Will add that to the design but need to think about the details. The insulation needs to be UV proof.

Was closing up a a 8563E after some heroic fights. Having learned from past experiences, I did a quick power up test after each layer of the sandwhich and sure enought, after layer 37,5 something started smelling foul and smoke spiraled out of the depths. Suspecting, as always, the power supply I dissasembled until I had it bare again and started the camera roling so I could catch the culprit in the act. Only thing is: it wasn't the power supply (you'll note my surprise as I was focused on the PSU and had to pan to the CRT driver. Odd thing is I can't find anything burned there.

I've sunk a *lot* of hours in this bitch already. I'm not gonna yield?

Went shopping this morning, arrived at Tesco's just on 8  o clock as they opened the doors, the queue was already snaked up and down the parking lanes 4 times and around the outside edge of the car perimeter, store side and then store front. I thought F that and drove down the road to Lidl where there was about 30 people in the queue, but even then it took almost an hour before I was allowed in the store. Once inside though it was almost back to normal with most stuff on the shelf in reasonable volumes. The shopping trip, to just 2 shops, next to each other, Lidls and FarmFoods, took almost 2 and a half hours  . 

I went to a local Polish deli and a greengrocer. I was very annoyed to have to wait 5-10 minutes to get in each of those. It looks like "YMMV"

There's something wrong with your link. No go.

Correct

I made the mistake of buying various craft things in poundland for the young one as well which are now stuck to everything.

Sort of like this

Nope. 404 error.

Perhaps an emergency switch is a good idea, too.

My first thought... honestly:   "Can you say 'Major Litigation', boys and girls...?"

Point being... it's one thing to present this as a DIY project for a third party; by taking part and building it they take responsibility for using it properly and safely. ie, ensuring it's wired properly and seals in all UV light, ensuring no inappropriate materials are irradiated with it, ensuring it doesn't get left on and burn someone's house down, etc...

But if any part of your company takes part in producing it or providing the components for any end-user... I can see a dozen different potential avenues of liability, just off the top of my head.

point taken. They may go through the effort to validate the design, though. The company is big enough to be able to do just that. We'll see.
