Sleep paralysis, lucid dreams, ghosts

1) I am familiar with lucid dreams, because experienced this phenomena at least twice. Other times are somewhat vague and unclear. Once I heard strange loud infernal sounds and couldn’t move my body, which reminded me descriptions of out of body experience. It’s difficult to tell whether I was asleep or awake, but it was scary. Maybe it was sleep paralysis.

Natural rights and human rights

Natural rights refer to fundamental human rights that are considered inherent to all individuals by virtue of their humanity, regardless of laws or governments. In the context of international law, natural rights align closely with human rights, which are codified in various treaties, conventions, and declarations.

AUX and smartphone in cigarette lighter

Smartphone works nicely with Blaupunkt SC 202 car radio DIY AUX but hiss is pronounced after 50+ volume level. It’s not big deal, because I don’t listen louder than 50% in car. Outside one don’t hear any hiss at all. Some people recommend to change capacitors on amplifiers but I decided to leave as it is. According to LCR-T4 old capacitors have high ESR but acceptable. To get less hiss, turn high volume on phone and low volume on car radio. Old cheap phone produces more hiss comparing with modern one.

When phone is charging in cigarette lighter, sound becomes distorted. Is it so called GND looping? Tried additional GND cable from car body to car radio, but it made no difference. Ideally I need to GND cigarette lighter same way as car radio. It’s pain...

Phone usually is charged 100% and it won’t discharge much in 4 hours, so I can live with this. As alternative I can use mp3 player with AA battery. Anyway task is accomplished – preserved original radio and added new functionality.

LFP Li-Ion LiFePO4 акумулятори

Вибираючи акуми, завжди шукаєш найнижчу ціну та найвищу якість, але чудес не буває. Багато спілкувався з китайцями. Переважно ухиляються. Все в них A grade. Траплялися приємні випадки — відмовляли від покупки говноакумуляторів, пояснюючи, що й як.

BMS для LiFePO4 батарей

Довгий час користуюся LiFePO4 батареями 6A-25A та не заморочувався BMS. Такі батареї відносно дешеві та в разі чогось їх не дуже шкода, а відповідна BMS коштує. Розбіги були незначні. Що там розбіги?! Ніколи не міряв опір банок і не зважав на здуття. Щоб витиснути з батарей максимум, потрібні мінімальний опір провідників та якісне з’єднання, але навіть 16 мм кабель створює незручності, що говорити про товщі. Краще починати з 24В, а не з 12В, якщо навантаження понад 1 кВт - економія на BMS і дротах - хоча як DYKB або ще яка дешівка... Отримали +90% ємності - батареї нові, а -80% - старі.
