More common than you think, but depends on the industry. we have kit at our place from the late 80's that is getting old (obviously) and the company that made it still gives us advice on how to fix it. its got a "computer" in it that to erase the data on it you expose it to sunlight!

By the way, you know there's no need to use gloves right? If you don't like to show your hands or whatever it's fine, but on our end there's no need to.

I think he meant his hands reflect too much light at the camera, oversaturating the image.

3:53 woah twisted pair mains cable, good for low EMI! 14:54 try clamping it at the long sides so the unsupported length is as short as possible, also screwing on the lid can help stabilize the part, had those problems multiple times at work when CNC-ing some housings

For cutting foam, try cryogenic milling (see video from applied science on the topic of cnc-ing rubber) the gist is, that you cool down your workpiece enough so that it becomes hard. At that point just cnc it like regular plastic but continue cooling it

It's called the notification bell. Helps you drop everything you do to watch their videos faster.

Talking a bout foam, I work for a company called Sealed Air who make a foam called "synergy" that you can CNC (its a Polyethylene based foam so the melting temperature is a bit low and it can be a little bit messy, but the sales pitch is you can recycle it), and our best competitor is a company called Zotefoams make a REALLY nice to CNC foam called Plastazote. Both CNC really well. They are both packaging foams and a few of our customers will 3D CNC packaging trays out of them. I'm scratching my head trying to think of a fabricator who may be able to give you a sample in Germany, but it has been years since i spoke to them last. I have just been asked to scrap a load of 50mm Synergy material, so may be able to box some up and ship some out to you if you would like a sample?

[@p_mouse8676]

Most of the time the temperature measuring device isn't the issue. Making sure that you're actually measuring what you supposed to be measuring without introducing another billion variables, is the hard part. Welcome to thermodynamics.

I wish more companies would have this philosophy like Arroyo. I mean we all are hobbyist, but most of us have a job in the field, too. Do these companies which never mail back or answer schematic or whatever request with "we dont do such things" to be picked by us ignored hobbyists as supplier for the companies we work for... hope you get what I am trying to say, its a bit late here :)

[@gnramires]

Amazing! It's interesting to see the different approaches to deal with temperature. There is temperature control, thermal isolation, there is material science/device design temperature invariance, there's temperature compensation (and software calibration), and finally there's the union of several methods to get the absolute best results! I believe quartz watches (e.g. casio) use a mix of stable temperature dependence with thermometers. The problem of course is that temperature changes can't be too quick, thermometer precision is limited, and the temperature may not be uniform across the entire device. But you do what's possible under small device constraints! Great video as usual :)

I do enjoy a good pair of well calibrated hands. You should wear them more often, they look really good on you.

[@tophalfofabarn447]

Did you use Belleville washers on the plastic screws mounting the peltier? Thermal expansion/contraction will change the thermal contact and ideal PID values over time and with temperature differential if there isn't constant clamping force.

Around here some CNC hobbyists like to use rigid carbohydrate foam for some machining projects. Unfortunately the supplier is very local and you may have to source material from specialty stores. Goes by many trade names but in this part of the world they use an old english word, I think it's called "wůd"

Good CNC'able thermal insulator - Wood

[@hullinstruments]

I’ve been hoping to hear something from him about this

[@unterputzdose122]

Hey Marco, u might be interested in "kieselgu(h)r" as an insulation material. I have seen there r sort of cinder blocks too, but not yet found a source how good it insulates compared to vacuumed variants. Some cold storage cell manufacturer use that vacuumed material, but it due it's complex manufacturing and fully welded cells, it is very costly for big(ger) scale applications.

[@tellurium3754]

You could try Etafoam, I only cut it using a bandsaw yet but it worked wonderfully so it might be cnc machinable

[@agiantfrog]

use high speed steel end mills for softer materials like foam and plastic, sharpness is key there

[@thegribbs]

High density EVA foam machines very nicely with aluminum or compression cutters. I use mostly 2 flute compression cutters.

[@JohnoLapse]

You need some CNC foam cutter endmills from datron! Then you can cut normal foam on a router.

HDPU is a pretty stable machinable foam or expanded PVC (sintra) but they are both ridged (sintra less so)
