These coin operated computers are not that hard to make since you only need a few materials and attach a few wires to make it work. I think you don't have to be a computer engineer or an electronic expert to build your own coin operated desktop computer. However, I would highly advice that you consult someone knowledgeable about electronics since this tutorial is not thoroughly detailed. Google is your friend to find more information about this.
I'm sorry for not able to supplement you with more detailed tutorial on this post but I do have some pictures that may help you.
To start making your own coin operated computer, here are some materials that you're going to need.
1. Coin Slot which will cost you around 200 - 300 Pesos. There's an expensive one that cost about 600 pesos but I tell you, they're all just the same because I have both tested the expensive and the cheaper one. I think you should go for the cheaper one.
2. Wire - at least buy 1 mtr of wire. You'll use this to connect your coin slot to the timer.
3. Relay - just go to the electronic store and tell them that you're buying a relay for your coin operated computer. They know about this.
4. Two diodes - you can ask which diode you'll need in the store.
6. 9v-12v Transformer
8. Power cable that connects to your monitor.
Please ask the electronic store about some detailed infos of those materials.
Those are basically what you need to create your own coin operated computer machine. Now the succeeding pictures may not be clear but I'll try to explain them to you guys.
The diodes, capacitor and transformer are connected. You'll notice in the picture that the capacitor's gray color stripe are facing towards the transformer. You'll also notice that the transformers 1 AMP text are facing towards the capacitors gray colored vertical line.
Checkout the diodes, how they are connected, you'll notice that the wire where you'll see a gray colored head are connected on the opposite side of the capacitor wire.
That's basically how you connect the transformer, diodes and capacitor.
Moving down, the image you see is how you connect it from the transformer to the timer board. Check it out.
Try to analyze a few of how its being connected - the brown and the black wires are basically attached to the timer board.
The pictures you see above is actually the back and the front portion of the timer board. On the first picture above, take a look how the wires are placed and soldered. At the bottom or the front portion, you'll see how the relay is attached and the wires are connected. This is now ready to connect to your coin slot device which also has some wires that you should connect.
[COLOR="rgb(46, 139, 87)"]The power cable are stripped off using a knife then attached the wires that goes from the relay part as you've seen on the previous pictures - this is where the power is cut off that supplies the monitor when the timer stops.
Finally, below is a picture how all of these are connected.
[COLOR="rgb(46, 139, 87)"]I hope these gives you an idea on how to create your own coin slot operated computer or computers that works using coin slot. It only basically cut off the power supply to the monitor.
Again I'm sorry for not able to give you a more detailed tutorial on this matter but I do hope you could find something similar to these topic but more thorough. If you happen to find it, please don't forget to share it in here.
