    IR Spectrometer Project: Is This Project Within My Reach?

    :) Thanks for that opinion @Deltaprime. I was coming to the same conclusion, in the matter of the far i.r. stuff. Near i.r. - just a bit longer than the wavelengths of visible light - is a lot more accessible because there's no need for a vacuum, and no need for ultra-cooled thermistor...

    ok then ... did you know that we no longer call it 69? It's 96 now, because the cost of eating out has gone up that much. okay that was not funny ................................. The professor teaching basics about electronic circuits asks the following question : Why does the capacitor...

    IR Spectrometer Project: Is This Project Within My Reach?

    mmm, well It turns out that the really quite far infrared is very interesting. Deep infrared that shines through a solution can be spectrographically analysed, and the results fed to a "fingerprint recognition engine", please. Tables of the fingerprints of millions of molecules are available...

    Diagnosing my failed CNC controller

    So, 21st century support. Meh. Some modern gear seems to be built on the same design philosophy as a ladder, to the Moon, made of stacked chairs.

    IR Spectrometer Project: Is This Project Within My Reach?

    Hi @bertus The near infrared would be easiest. Physics suggests that the longer the wavelength, the more noise - I don't have much of a clue when this starts to matter with modern components. That's the kind of question that lurks behind my ear and makes me wonder. Thanks

    Diagnosing my failed CNC controller

    :) Have you contacted the technical support team at Buildbotics? Sounds like a good first step to me... Otherwise as @ahsrabrifat has suggested.

    IR Spectrometer Project: Is This Project Within My Reach?

    Hi Everyone I'm considering a project, and wondering whether you think my approach would work. (I also have to consider expense.) I think that I can make a diffraction grating suitable for mid infrared spectroscopy. I'm thinking of the range between 2.5 microns wavelength and 7 microns. The...

    IC Insertion tool

    :) Yes, that method works very well, and doesn't require any tools.

    Is this a better idea for my Variable Bench Power supply?

    yes another necrotic reanimation. zombies will be next - I'm glad you are good at putting these things to rest

    Is this a better idea for my Variable Bench Power supply?

    I just got an email notification that this thread had a new reply - that's not the case but someone looking after the forum might want to know about the mistaken notification

    IC Insertion tool

    Hi Once or twice I put a chip into an engineering vise and squeezed the pins parallel. It does work... When I got more skilful, working as a circuit board tech, I would do much as Harald Kapp - get the legs on one side in the proper holes - then I used my EFT-POS card to press all the opposite...

    :) This is allegory... In real life, people get facts into square holes, but often find it requires a lot of force to do so. That's because the facts are rusty.

    turbo jet fan [DYI] - feedback appreciated.

    It looks like the op wants to make a ridiculously powerful, handheld wind generator - on YouTube I saw one that could blow the water out of a hand basin! :) If it were me I'd look at model aircraft gear.

    Electronics seems like magic!

    Edison is a man to admire - if you're a wannabe inventor. Just wow! His stuff didn't get made by accident - nor by lightning flash inspiration, mostly - he used teams of investigators to put in man-years of research into materials and their properties. In one exception to the methodical...

    Electronics seems like magic!

    Hi @Omega Supreme I keep finding myself wanting to suggest that you put a strengthening armature inside the (tubular) antenna... is that what you were fixing? Just something stiff inside the tube to keep it the right shape. I hope that's ok
