Not in the model show in this instruct-able. That design has been discontinued. Other designs are available.http://www.retrobuiltgames.com/diy-kits-shop/

Why thank you!

yup

It can. Since you're in college, I'd be doing you a disservice if I just handed out answers :)Instead, how do you think you would do it? Justify your solutions. I will let you you know if you're one the right track or not.

It can be done. At 10 pots, you might opt for an arduino mega. You would ideally have 10 moisture sensors, and then 10 solenoid valves to control watering, therefore you'd need in theory 20 pins to monitor and control everything. I have seen some lower voltage valves that would be use for this application, the catch is the valves need about 4-6 psi to actuate and seal properly. Keep this in mind when you locate your reservoir. Adafruit has these soleniod valves i mentioned.

Don't discard the tft's Power button. "Most" (and i emphasize most in this case) monitors will stay in the "on" state after you remove power. This means the lcd will always display whatever input source last selected once power is supplied to the LCD. But to be safe, i usually hot glue the power button (and setting buttons) somewhere inside the cabinet just incase i need them. It's never an eleangat solution, but don't toss that tiny button strip.You would really need to measure current to know if 3A is enough for all this. good how to measure current draw as measuring will tell you what you should do. Always give yourself extra when it comes to power draw.

22 AWG for pretty much everything. Yes, you can share the LCD with the 12V circuit.

6A would be suitable- under the assumption you are not doing an LED backlit marquee.

It never hurts to have a higher ceiling for amperage.The 8A supply is fine and will not hurt anything, assuming it's the same voltage.

if you watch the video you can see me set the time at power on. If there is a power loss you will lose the time of day, but the watering interval and time of watering will still function- just at the wrong time.

I could put them in the water :)

Thanks. A bigger reservoir was on my mind, you can swap out for a larger plastic tub if you had it. I was on a budget so this what I had as far as plastic tubs.I would agree with the filling hole. My original intent was to vacuum form a tray to trap any water spilled from filling plants.

the secret it out! I like how they put a box together....

Thank you! The 3D model was made in 123D. I am not sharing the box as it is sharing the development of another project.

I would check to see if your JAMMA board has a built in amplifier, before connecting it to another amp. If it doesn't, then yes, splice the wires into a 3.5mm plug.
