So I was trying to get my naff speakers to play Whitney Housten properly. No highs, no lows, must be Bose. But Windows 8 has no treble or bass controls, so after some research I realised I had to work out the make and model of my motherboard, and get the driver for that. After more research, I found a 300MB download. Got there in the end. (God, surely it doesn’t need 300MB). So I’m flipping through the different equalizer presets. Cave, Concert hall, Arena, Sewer pipe, awesome, just what I had in mind. Oh wait, “Padded Cell”. Now that brings back memories. That’s the one thing I miss: the acoustics of my padded cell. They really were second to none. All this hassle was worth it.
As a handyman, or electrician, or DIYer, I want to be able to run things off my van’s batteries, without hassle, and without needing to worry about leaving enough to start the engine. For example:
- An inverter to run mains appliances such as a charger for my cordless drill’s battery, my mains-powered soldering iron, or a laptop PSU.
- Various 12v appliances like a low power kettle, USB chargers
So I want the system to be flexible. I want it to save time, be convenient, but also prevent headaches like a dead battery. I also want it to be road-worthy, generally safe. So what will this system need to do / need to be?
I want convenient access to sockets with power when I need them.
Simple version: the sockets all share the same power, and will be energised if any of the following are true:
- If the key is in the ignition (with or without the engine running)
- When any loading bay doors are open
- While a count-down-timer that I manually started is still going
That should minimise the chance of the battery going dead, since either the van will shortly be started, or the circuits will only be energised for a short time, or I manually switched the circuits on and don’t need to remember to turn them off.
Each socket will have its own fuse. Also any controlling circuitry will be separately fused. The design of the final circuitry will not interfere with any other circuits in the vehicle.
So how will this look? Circuit diagrams coming soon, ish….
