  1. Pra que todo esse circuito numa esmerilhadeira? Que loucura!
    Tenho uma Einhell que deu problema essa semana, sรณ tinha esse circuito a mais nela de resto era um micro switch… cortei fora o circuito e liguei direto na bateria, pronto รฉ sรณ usar.
    No soprador da Einhell de folhas (que nรฃo sopra folhas) queimou um circuito de velocidade (1 e 2) tambรฉm liguei direto.

  2. Excellent work! Did you remove the old potting for the electronics, and if so, how?

    Does the rotor just slide in? I thought you'd need to slide it in before closing the shells so that the bearing is seated properly.

  3. Flawlessly done Brother โœŒ๏ธ

  4. Looks great, I would have liked to see the opening of the tool. I'm always more afraid of not being able to rebuild then to repair the pcb.
