I was feeling a little bored and thought that i would play with some soldering (:
Nowadays with so many devices that can be charged from USB, you wouldn’t probably want to switch on the PC just to charge something. Thus i created a USB power supply that can charge all my devices without switching on the computer.
Ok, now you may ask, why can’t i just get those USB charger things that just plug into the socket? Ahha, the thing is, mine has the same voltage (5V), but much more current to give devices that extra boost in power! and, it comes with 4 USB ports to charge many devices together (: 2nd reason, i’m just bored and wanna play (:
In the 1st picture you can see the materials i used (and did not use, for some reasons). You can see 8 USB sockets there, but in the end i only used 4 for the product cos i was feeling tired, and would be problematic if my hand slipped while soldering or stuff. I did not use the LEDs, becos, well, i was in a rush and forgot to buy resistors. (lol) In the 2nd picture you can see my gas powered Iroda soldering iron set, which i am thinking to change to an electric one as gas ones spoils easily. You can also see the Fluke 116 multimeter that i bought last year as a birthday present to myself (: And i love that multimeter (: its the pinnacle of all multimeters (:
In the last picture you can see the whole final product together with the rest of the parts that made it work (: Parts of the picture are labeled with numbers, which will be explained below:
1. A desktop ATX power supply unit (PSU), that provides the extra currents.
2. A small little wire shorting the power on pin and the ground, to keep the PSU running. (I was planning to make it a bit more presentable, but it will do for now)
3. Cut the 5V rail and soldered a female USB connector onto it, with heat-shrink tubing to make it neat.
4. Connected my product to a male USB connector, also with heat-shrink tubing to make it neat.
5. Connected both USB connectors together.
6. Charging of multiple devices! (:
Ah, yes. Thats the extra touch (: i made the connection between my product and the PSU to be a detachable USB, so that it will be interchangeable with other USB stuff (: And the reason why the product is in the form of a circuit board when just plain wires can do the trick? cos circuit boards are a lot more fun, and of cos presentable (:
