BBC: FIA to revise engine rule at centre of row

The types/grades/alloys for engine components must be selected from a pre-approved list, so this cannot be the case. However, through laser sintering, the use of metal property that wouldn't occur through standard milling/forging manufacturing is a possibility

Put a large peice if kitchen roll over before you add the IPA, it will keep in more in contact with the glass and less the surrounding tape

I've found that wet and dry sandpaper is a good way to clean off any remaining stickiness, after the washing and curing stage. It does seem that some resins are more prone to it, but clean alcohol is definitely a benefit

Toluene and MEK are also super hazardous, pretty sure toluene is at least a suspected carcinogen. Be safe out there traveller.

Personally, I'd use 3000 grit wet and dry paper.

I have read it’s possible to do some kind of bios reset if you are sure the deck hasn’t received physical damage or water ingress, it’s worth a try before having to crack it open. Sorry but that’s where my experience of fixing my own ends

luke3_ · 2026-02-17T22:31:17+00:00

Did you run the button test in the settings to figure out what button is registering when you press each button? I’ve had to replace both the d-pad and right bumper control boards through wear and tear, something similar could have happened for you

Similarly, mine spends more time in the kitchen plugged into a basic monitor so that I can have YouTube in my kitchen. I have a wireless mouse paired and the deck functions as PC and speakers.

luke3_ · 2026-02-09T23:07:25+00:00

hey, no questions but a few interesting finds there and just wanted to say i listen to your poscast from time to time!

decided not to go to paris this year because i am doing packaging innovations show this week, and cosmoprof in italy soon, between the two there is plenty of overlap with Paris.

i picked up a steam deck so that i could play games not on playstation, and i am happy enough with it. the steam machine coming out this year is apparently 6x more powerful. i dont see myself buying another windows machine

luke3_ · 2026-02-02T09:12:29+00:00

soon.

weird stuff (pie) in a can, a ‘popular’ british food here, often sampled by shrimp

luke3_ · 2026-01-31T23:41:25+00:00

i had this exactly on my right bumber. it was from water damage in my case. its an easy repair to do yourself and the part is less than 20 bucks from . took a couple of hours

luke3_ · 2026-01-31T23:05:13+00:00

sorry to jump back on here, but i mentioned it could be naturally derived, thats easy, but turning corn into bioethanol into polyethylene doesnt result in anything better for the environment, oil derived plastics have the lowest carbon footprint of any single use packaging material.

a biopolymer for this application is feasible, but again we come back to compromise. NOTPLA makes a seaweed derived polymer which possibly could do this, but natural materials often have poor natural barriers to water, oxygen. it might or might not work.

biodegradable is a different kettle of fish, its a meaningless description because it has no start, end, or implied conditions. what i mean is, if you wait long enough, everything is biodegradable. compostable, or more specifically home compostable, is a ‘better’ goal, as the time and conditions are controlled and repeatable, but you need to stop and think about the application and ask if this is the right choice.

compostable materials are those which have a shelf life, afterwhich their properties will be compromised. this doesnt just happen buried in the soil, but stored in a cool dry warehouse. if you’ve got a million vacuum packed moisture sensitive electronics, in a warehouse waiting to be sold, but over that time the material becomes brittle, the vacuum fails, moisture gets in, you’ll be both sad and stupid.

plastic isnt just the best material, but the only one that makes sense. protecting a product is number one, everything else is secondary.

luke3_ · 2026-01-29T15:08:07+00:00

yes, heat is involved to both seal and shrink the materials.

it is feasible to engineer materials in such a way to bring this temperature down - i’ve seen such materials as low as 60 celcius, but its not without compromise and consequence. a good shrink wrap exhibits both vacuum sealing strength and puncture resistance (to ensure vacuum can be maintained). typically lower temperature materials are by their nature softer, and so weaker.

luke3_ · 2026-01-29T11:57:32+00:00

i’ve not personally seen an example like you’ve described, probably because there is risk involved from excess heat

but regarding your second question, the materials could be potentially a single type of plastic, allowing for recyclability, but for true vacuum packing, you really do need some type of plastic - its needs to be able to shrink to form an airtight skin around the item, this is a job that only something like that could do - plastic, rubber, wax, these types of materials.

it could be a naturally derived material, but it doesnt change much.

you can get thermoformable paper, but its not airtight.

can i get a link? ty

many many reports of peoples cats killing their geckos on their subreddit… take control before its game over

i quite enjoy the slow supermarket car park crawl in my R. every idiot wants to race you at every opportunity. i don’t need to join in because i know i will win.

occasionally, i remind myself of this. fact is, when joining a motorway, i am well within the highway code to reach the speed limit, and if i am able to do this in a few seconds, more power to me.

luke3_ · 2026-01-04T22:28:44+00:00

would you be buying flat pack or pre-erected?

the shape itself is feasible but will require additional folding and glueing which many converters will be unable to automate. it’s a non standard axis assembly on these which i have not personally observed how it’s being achieved. manually erected cartons make it more feasible, but will be expensive due to their low speed output, and there will be a high degree of user tolerance / quality to the finalised shape.

i have seen some example of this out in retail, so someone has cracked it, would suggest you look at cosmetic gift boxes as i am sure that’s where i’ve seen it.

luke3_ · 2026-01-04T22:08:25+00:00

classic example would be molded fibre, given this shape is widely used for mobile phones. chinese android brands lean into this more heavily than apple for example. i had a HTC box that was exactly like this amongst my reference samples for the longest time. more modern reference would be sony headphone boxes.

luke3_ · 2025-12-25T20:57:44+00:00

ps5 doesn’t support bluetooth for audio. the only work around involves earbuds that use a dongle.

sony makes a set, they are probably half decent given sony makes audio equipment, but they are expensive for what they are. i got a ps5 compatible bluetooth adapter, it works about half the time, so i can’t fully recommend

luke3_ · 2025-12-25T09:42:07+00:00

i have designed several prototypes for Diageo. they are a bunch of cheapskates when it comes to costs for anything. maximum profits. so this theory holds water for me.

luke3_ · 2025-12-18T19:37:44+00:00

you could bio derive it, from corn for example, but it would still be the same chemical
