  1. Doing SPL tests on an advanced PA system.

    Important when you do this work is to have proper PPE on your corpus (latin).

    The system was running between 37dB SPL (sound pressure level) and a massive 110dB SPL. Note1

    It's important to keep your corpus safe so a proper set of earmufs is a must.

    This PA system can run all the way up to 125dB SPL but that level was not needed in this test. The signal limiting systems were tested with this setup, since those are the last stop between your speaker systems the signal and burning speaker coils...

    Note1
    My dB meters are calibrated so the values are accurate. I use one consistent system of calibration accorss all my dB meters to get similar results on similar acousting ENV

  4. Ah yes, the site dedicated to 150 years of staring at glowing glass boxes, because nothing says cutting-edge #technology like a lecture on 1969's hottest #educational gizmos. 🤓🔍 Dive into the thrilling world of #electron #guns and #Helmholtz coils—perfect for those who find paint drying a bit too exhilarating. 🎉📺

  5. J'ai terminé le bracelet en modules égyptiens ronds !
    Décidément ce fil de cuivre est beaucoup trop épais, je me suis vraiment ruiné les mains à essayer de le plier. Notre part il y a plusieurs raideurs de cuivre et celui-ci n'est pas parmi les plus souples ><.
    Le résultat est un peu trop épais pour ce que je porte mais ça rend quand même plutôt bien !

  7. Today I present to you....the lateral #induction #launcher I built in my 20s. Two opposing hand made pancake #coils with a 1/8" #aluminum disc between. #Discharge #capacitor bank, disc shoot like a gun...err....the #Unreal Tournament weapon we all loved most. This cheaply constructed prototype blew up after 5 shots or so. #science #highvoltage #electricity #NineLives

  9. How does it #sense the #speed the motor is turning at? The motor only has 3 terminals, and those go to the points between the three motor #windings. There isn't another #signal coming out of the motor to tell the #controller how fast it's actually turning.

    Except...

    Apparently, while driving those three motor windings, it is #simultaneously sensing the back-#EMF that the windings (which are essentially #electromagnetic #coils) produce from those same terminals.

  19. Ich habe echt übel #Schiss davor gehabt mir meine #Coils selbst zu #Wickeln. Ich gebe ehrlich zu dass ich das #OhmscheGesetz nicht wirklich #verstehe. Aber mit einer #App zum #Berechnen des Coils ist das eigentlich ein #Kinderspiel. Aktuell verwende ich #AlienWire wenn der #Draht alle ist steige ich auf #Twisted #Clapton um. Macht das #Vapen deutlich #Günstiger und #schmeckt mir deutlich #besser. Mein nächster #Atomizer wird ohne Zweifel ein #RDA.

  21. Einfach oben den #Deckel abziehen und das #Wickeldeck liegt frei. Dazu werden die beiden #Coils von der Seite angebracht, man hat also sehr viel #Platz. Der #Tank wird von der #Seite befüllt. Einfach den Deckel drehen bis die Öffnung dafür frei liegt und ab dafür.

  23. Mal wieder #Schlaflos. Gerade von meiner #Auszeit (gemütliches #Sitzen an einem #fließenden #Gewässer bei #BlackMetal und Dry Tonic Water) zurück gekommen. Nachdem nun meine #Bestellung mit 10 Metern #AlienClapton gekommen ist habe ich den alten #Draht verbraucht. Hat für genau 8 #Coils gereicht. Wenn ihr #Bedarf an #handgewickelten #Coils habt einfach melden, gibt ja die Post.
