Do you think I should test my constructions before publishing? :-)</p>

<br />
This is my first attempt at the wiki so I hope I will do this right.<br />
<br />
If you are really looking for an el-cheapo solution and all you need to do is to turn a solenoid on and off at adjustable intervals, take a look at the 555 IC.<br />
<br />
It is about $1.69 at Radioshack, then you need two potentiometers (turning knobs), and a handful of passive components, getting away with the uC and laptop altogether.<br />
<br />
With the values in the schematics, we would get 2 seconds on and 6 seconds off when putting the knobs in the middle.<br />
<br />
I don't know enough about triacs so I would probably go for an old-fashioned relay and a transistor to amplify the current for the coil and isolate galvanically.<br />
<br />
The relay could then in turn be used to control the air-solenoid. <br />
<br />
'''Always be careful both with high currents, high voltages and pressurized air!'''<br />
<br />
I took most of the construction from:<br />

==BOM==<br />
*2' x 2" PVC pipe<br />
*2" flat PVC cap<br />
*2" Spigot x 3/4" Fips [http://www.plumbingsupply.com/pvc.html#plug] [[Image:plug.jpg|thumb]]<br />
*3/4" male thread coupling<br />
*[http://www.lowes.com/lowes/lkn?action=productDetail&productId=61252-34146-M31SL&lpage=none 3/4" brass check valve]<br />
*2 x 3/4" male threaded PVC plugs<br />
*2' x 3/4" PVC pipe<br />
*2 x 3/4" hoses long enough to go down the well<br />
<br />
==Construction==<br />
#Ream out one 3/4" male threaded PVC plug with a 3/4" hole for the 2' x 3/4" pipe and attach them.<br />
#Drill two 5/8" holes in the flat PVC cap and tap them to 3/4" for the air in and water out 3/4" male threaded PVC plugs. Use plumbers tape and attach the plugs. Glue the PVC cap to the 2' x 2" pipe.<br />
#Remove the spring of the metal check valve like in the hydromissions slapshot instructions.<br />
#Glue the 2" to 3/4" plug to the other end of the 2' x 2" pipe, attach the 3/4" male threaded coupler and the 3/4" check valve.<br />
#Attach the hoses to the plugs with plumbers tape and clamps and test the pump.<br />
