Massimo Cappello  Udine - Italy. I like exploring the mystery of Nature. I'm a modest Hammond organ player too, working hard for improving, every day!

Artisanal advertising in Naples. This guy looks to be a GREAT commercial! Offering anything you may need, almost all sort of stuff, all together! From a porcelain sink, through a terrarium for you pet python, all sort of household appliances, antennas, furnitures, tools, down to a pair of boots with "suspenders" and, as he wrote: much more!!!

Restoring by myself my 1963 Hammond C3 - Now started the BIGGEST job: replacing 54 years old waxed paper capacitors on tone wheel generator. FIRST step: measuring actual output for each of the 91 tones (still with original capacitors in place) using an oscilloscope #hammondb3 #hammondc3 #hammondc3witpercussionšŸ˜ #hammondb3organ #hammondc3organ #hammondc3again #rockmusic #progressiverock

Restoring my 1963 Hammond C3. Listen to the difference: upper manual with original (54 years old) felts. Very noisy. Lower manual with NEW felt stripes...perfect!!! #hammondb3 #hammondc3 #hammondc3witpercussionšŸ˜ #hammondb3organ #hammondc3organ #hammondc3again #rockmusic #progressiverock

The most elegant James Bond ever...Thank you and RIP Sir Roger Moore #jamesbond #jamesbond007 #007 #rogermoore

Same picture from the opposite side. CO2 Laser is on the left. I used LEGO bricks for the adjustable arm holding a gold plated molybdenum mirror, the grey disk visible on the right. #makers #makerfaire #laser #physics #electronics #rubylaser #ndyaglaser #co2laser #science #quantumphysics #maker #optic #optoelectronics #optoelectronicslab #education #gaslaser #lego #legomaker

Ready for interesting Optics experiments with my homemade CO2 Laser and artisanal optical bench. I used toroidal magnets for placing adjustable lens supports on the top of the bench where I glued a sheet of steel. You can also notice the fan for removing the smoke I have integrated into the bench. This will be my masterpiece I'll show at the next Mini Maker Faire which will take place at the International Centre of Theoretical Physics "Abdus Salam" in Trieste Italy next June. The lenses here are yellow because they are made out of Zinc Selenide (it's a type of salt) because ZnSe is transparent to the very far infrared beam generated by the Carbon Dioxide Laser (10,6 micron). Normal optical glass is opaque to this light and it would melt down!!! #laser #physics #makers #makerfaire #laser #physics #electronics #rubylaser #ndyaglaser #co2laser #science #quantumphysics #maker #optic #optoelectronics #optoelectronicslab #education #gaslaser #lego #legomakers

Slow Motion (with sound) of my homemade Neodymium-YAG Laser hitting a piece of black plastic. Thanks to @eedoardo for this video. The pulse lasts for 0,1 milliseconds. Instantaneous power reaches kilowatt range. The light of this laser is not visible to the human eye (wavelength is 1064nanometers in the infrared region of the electromagnetic spectrum) the sound is generated by the sudden air expansion due to the high energy of the pulse. The material that generates the laser light (active medium) is a small rod of YAG (Yttrium-Alluminium Garnet) doped with 0,5% of the rare earth element Neodymium. Actually are the Neodymium atoms that generate the laser light; while the YAG is just "hosting" the active Nd atoms in its structure. The energy which allows the Nd-YAG crystal to generate the laser pulse is provided by a powerful Xenon Flashlamp (similar to those used in photography yet more powerful) which illuminates the crystal with a short burst of ordinaty light. This type of laser is widely used in industry (spot welding) and in medicine. It is also used for removing tattoos. A similar laser is also installed on the NASA Rover sent to Mars few years ago for testing composition of Martian rocks. The light generated by the laser pulse when impacting the rocks is analyzed by a spectrometer for identifying the elements composing the rocks. #laser #physics #electronicsare #makers #makerfaire #laser #physics #electronics #rubylaser #ndyaglaser #scientist #science #quantumphysics #maker #optic #optoelectronics #optoelectronicslab #education

Another picture of my homemade Ruby Laser while it burns a hole on a razor blade. The beam of red monochromatic light (694,3 nanometer) is clearly visible as it travels from the Laser (right) up to the focusing lens. #laser #physics #electronicsare! #makers #makerfaire #laser #physics #electronics #rubylaser #scientistinthemaking #scientist #science #quantumphysics #maker #optic #optoelectronics #optoelectronicslab #education

1 millisecond pulse from my homemade Ruby Laser punches a hole on a razor blade. The thin microscope slide protects the focusing lens from the sparks of burning steel. #laser #physics #electronicsare! #makers #makerfaire #laser #physics #electronics #rubylaser #scientistinthemaking #scientist #science #quantumphysics #maker #optic #optoelectronics #optoelectronicslab #education
