I used to work on imagesetters which require very precise beam positioning; the moving mirror carriage assembly had lead weights stuck to it to move the resonant frequency much lower than the excitation frequency from the mirror motor and fans.
25:49 What you mention here about slow rise time makes me wonder; How do you deal with EMI compliance? A lot of the installations are obviously one-off, but I am pretty sure in the EU you'd still need to satisfy CE EMI (and general safety) directives, or are these exempt of EMI in the US/UK? EMI testing is horribly expensive, especially for such large outdoor installations you are building. Never mind that you often deal with high data rates (with fast switching), and thus probably a lot of EMI in general. Of course, at least in case of CE, the directives do not mandate any testing, merely that the manufacturer is reasonably confident that it would pass the requirements. Hence maybe some simple testing is sufficient, or maybe you just design your boards for best possible EMI performance and call it 'good enough'. A last option is of course that you are contracted or sell them as part of a bigger installation, and leave the EMI hassle as a responsibility to the customer/final installation. This would perhaps be a very interesting topic, not really highlighted often.
Just repaired my CT55JW microwave. The control board *does* have a mylar sheet in mine so damage limited to one board. It had a nice black burn mark on it. The broken pcb track was easy to spot. Bridged it with some wire and solder. Oven works fine and the bulb/turntable are working again. Swapped bulb for LED so will hopefully not have this issue again. Thanks for the inspiration. Saved me £250.
This reminds me of why I usually loathe working with industrial designers, especially the ones on the artsy end of the skill spectrum. Grumble, grumble.
This has happened to my Panasonic NN-CT55JW. Bulb has blown but now the turntable doesn't work at all. So to save 5p I've now lost a £250 appliance which they deliberately make impossible to repair. Thanks Panasonic. Why are they still even using 1930s bulb technology in the 21st century?
Hi Mike, Thanks for your video review of Tongou RCBO. I'm looking for a WiFi RCBO for my home because sometimes (when it rains and thunder) my home RCCB trips and I have to switch it on manually. It is ok when I am at home but when nobody is at home, no power at home until we come back and switch it on manually. That is my main requirement. Do you have any recommended brand of RCBO which can be controlled by a app remotely? Or you are telling that any WiFi controlled RCBOs are useless and not safe for a circuit?
You get that speckle reduction in laser cinema projectors (with vastly higher powered lasers). It works by changing the path lengths by altering the number of bounces it takes to get around the coils.
Not all people like Americans and Brits are stupid, this has a lot of applications I'm using smart brakes in my pool main switchboard, pumps, heating,g, and lighting and so far I haven't had any problems with it. Regarding safety, I didn't have any problems with it. Es electricians, I find your video is a little bit messaging.
Hi Mike...let's say you were doing some engraving and power go out can it resume where it was cause I have tried to find something and I didn't find anything concerning that
„aesthetic wankery“ 😏 Oh well, in medtech there is nearly no limit to the cost of the outer surfaces, especially if they have to comply with GLP regulations. I‘m slightly surprised at the uneven surface outside as it doesn’t seem to be beneficial for cleaning. Have yet to watch the whole series but I assume they‘re using the massive case to keep the inner temperature within a defined range compared to the temps in the lab it would be installed in. 400k is not a surprising price to me at all, yes that outer finish is for the fuzzy feeling in this case. The microfluid consumables are single use and they will be the main cash cow next to the sensor. Fascinating stuff, don‘t get to see this every day.
These devices are engineered and validated for a specific purpose and in the end that purpose is what will define the requirements. The cost isn’t the main deciding factor, the question is if the device and the manufacturer can fulfil the requirements posed by the customer. Those devices must look neat to the cleaning crew, like the synchronous blinking BMWs.
it's a wonder the thing worked at all with all the fiddling you did with it prior to attempting to weld anything. it would also help if you knew how to weld. i would also hope that anyone buying one of these understood beforehand that these are not designed to be used to fabricate container ships or oil/gas pipelines.
The Curie Effect will kick-in on the transformer as it approaches the 'Curie' point of the magnetic material ... it will just start to act like it was 'air' and not a transformer (sort of).
I had one of these years ago and was able to free the intensifier from it by very carefully heating the front glass plate. It was bonded to the IIT subassembly fiber optic array with what appeared to be epoxy. The IIT unit lived in a home made X ray imager for a long time ❤
I can't disagree with most of these comments, especially the "Apple-level aesthetic wankery". OTOH, If your health-care team (and mine) are relying on machines like this to diagnose what is wrong with you, or to analyze what kind of therapy is most effective to make you better or keep you alive, I am somewhat reassured at the level of insane build-quality and intricate custom manifolds, etc. and automation of what was probably a rather fiddly series of laboratory tests. This illustrates how much mechanical/electrical/chemical/billogical/optical automation is taking over things that literally affect our life, health, and safety. And when A.I. starts reading our medical charts and talking to machines like this, we are handing over the welfare of human society to the machines. Let's try to not interface things like this to "Skynet" (or SKYNET). 😲
Just found this video in 2024 but still glad you have it up. I've always been interested in old video/audio technology (especially analogue television) so to see how old 35mm surround sound audio finally works is a wonder. Cheers for the video and keep up the good work.
Thanks for sharing. Helps put sone visual to stories my father used to tell. Do recall a story from my dad on likely a similar device that was probably on phantoms. Was running a training shop with westinghouse rep and the rep forgot to follow all the safety precautions and had the front lens off. My dad pointed out the failure to which the said “no its fine there’s safety on this” as then the laser started firing across the classroom leaving dots on the back wall 😅
I use that exact same app for some of my wifi switches for turning lamps on and off. To rename a device, just touch the little pencil/paper icon at the top right (you can see it there around 11:40 and on)
Thank you for this video, sir. I'm building a motorcycle and just picked up one of these modules with the laser to install as my headlight. I've been looking for a on it and couldn't find anything. Are you able to share any pinouts or amperage/wattage in addition to what you mention here?
