Anime - Japanese Animation
Baka - Japanese word for idiot or fool
Loosely put an Anime Baka is someone who's crazy about Anime. However interpretation's may vary. I tend to think of Anime Baka as meaning something like drooling fan boy/girl.
Wrote this a long time ago. Too short for an article:
Perverted - Hentai in Japanese. But the word pervert means deviation from normal or accepted. So, how can all guys be perverts?
Did you ever notice that the sex scene in the movie is generally at about the same realative place as the guitar solo in a song?
Auto Pump Circuit
I'm trying to build a auto pump switch that is more powerful. I have some new pumps that draw about 4.6amps of current. My normal auto pump circuit is good for 2 amps of draw max and would quickly burn out at 4.6amps.
Here is my initial pump circuit that I copied from an old pump:
Here is a new possible design. The idea is to use the previous pump auto circuit as a trigger for a larger power transistor. I am not at all sure that this works and the TP101 transistor is a NPN transistor and not a PNP transistor.
I think I may have to get a similar PNP transistor, perhaps a TP104 and then re-arrange the wireing to get this to work. I'm going to read up on the differences between NPN and PNP.
The setup shown below does not work, go further down for something that does.
The setup below WORKS! This plan isolates each circuit with the one circuit controlling the other. The sensor circuit operates on the positive channel, where the high power pump switch is on the negative channel. One sensor can actually connect to the emitter of the TIP101 which is essentially a ground for simplified soldering. I just tested this on my desk and it spins up fine. You can touch the sensors with your tongue and feel the tingle or water works just fine also.
The TIP101 Heats up quite a bit which makes sense as it's a power transistor. Probably any high amperage NPN transistor would work just fine, the higher amperage the better. I have heat sinks on both transistors and they do get hot. Also I'd mount them upside down on the pump so that the heat sinks would be submerged sooner rather than later to help dissipate heat in a constant on situation.
The screw mount on the TIP101 also seems to serve as another Collector, but as it is wired to the ground of the motor this is probably not an issue. Still I'd probably smear some shoe good (or other insulator) on the can so that doesn't do something weird. I generally do this to mount the electronics and insulate them anyway. Also I generally silicone all the important bits afterwards to protect against random metal parts touching live wires.
