Ángela Stella Matutina<p>Buenas tardes, miserables.</p><p>Un <a href="https://social.treehouse.systems/@angelastella/112488160085814379" rel="nofollow noopener noreferrer" target="_blank">toot que mandé la otra noche</a> me hizo recordar: de chica, no llegaba a los diez años, inventé sin saber lo que hacía un transmisor de chispa. Bah, hubiera sido un transmisor si lo hubiera modulado siquiera con una tecla; más bien un generador de ruido: lo captaban las radios AM y <em>nuestro televisor valvular</em>. Sí, así de mugriento era su espectro, llegaba hasta VHF.</p><p>Consistía de un motorcito a pila con las escobillas en muy mal estado (esa es la parte de la chispa), seguro rescatado de algún juguete roto, en serie con una bobina que lamentablemente no recuerdo de qué dimensiones ni cuántas vueltas era ni si tenía núcleo, que actuaría de antena y con su modesta inductancia y también escasa capacitancia parásita le daría <em>alguna</em> forma a la emisión del cachivache.</p><p>A distancia de dos o tres metros creaba "nieve" en la pantalla de la pobre caja boba y en un mal día (tenía muchos, estaba al fin de su vida útil) lograba que se desenganchara el sincronismo vertical.</p><p>De más está decir que tuve que dejar de usarlo: interferir con la radio y la televisión en una casa donde vivía una señora jubilada, una ama de casa y un hincha fanático de Estudiantes era pecado mortal.</p><p>Seguro que se puede lograr por lo menos una fracción del efecto con el famoso oscilador que aprovecha el contacto "normal cerrado" de un relay, y si nos ponemos exquisitas, hasta sintonizarlo un poco. Pero en serio, no lo hagan salvo que tengan inclinación por el sabotaje electromagnético.</p><p><a href="https://social.treehouse.systems/tags/Electr%C3%B3nica" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Electrónica</span></a> <a href="https://social.treehouse.systems/tags/Electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Electronics</span></a> <a href="https://social.treehouse.systems/tags/HamRadio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>HamRadio</span></a> <a href="https://social.treehouse.systems/tags/RadioAfici%C3%B3n" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RadioAfición</span></a> <a href="https://social.treehouse.systems/tags/SparkGap" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SparkGap</span></a></p>
