At Broken Arrow Ministries we use the life skill sport of archery and share the gospel of Christ to at risk youth and families at festivals, concerts and family events we promote. We are a non profit with little to no finances. (Facebook/Broken Arrow Ministries Inc). My wife and I support most of the events and archery classes I teach, these monies contribute to cover the costs.
**
we are not asking for money, and do not ask for money. we are only asking for assistance with ideas to make the events stand out to attract the teens and young adults.**
We have an archery venue with 15 stations, 100' wide and 45' deep. persently these 3D targets are stationary. Sometimes we use a rope and pulley but this has proven to be very labor intensive. We would like to have them move, similar to a garage door opener to open and close. These targets would move up and down. The use of a garage door system is about 250$ per unit and keeping track of all the remotes will add frustration. So I thought of using a popup system and and using a PLC to control trigget times for each target. Using a PLC for each target is more costly then the garage door systems. (even used).
If each target had it's on circuit board (all being the same with same settable delays function) the PLC could command a random sequence for each target to popup!
I can fabricate the stand, obtain used motors and new for about 45$, build a circuit board for about 30$. each target would be under 100$ with the exception of materials for the stand.
Here is the idea...
Build Objective 1ten)
1.Have a wireless command to start (future option)
2. Button is pushed and released, operates motor CW to move target (UP or forward)
3. Target moves to desired point and stops motor (circuit resets till button is pushed again)
4. Stopped target sets a time on delay to start motor again CCW (Down or reverse).
(Programmable delay start time for 0, 3, 5, 8, 10, 13 seconds)
5. Target moves to desired point and stops motor. (Circuit resets till button is pushed again)
Build Objective 2: (Two)
1. Have a wireless command to start (future option)
2. Button is pushed and released, operates motor #1 CW to move #1 target (UP or forward)
3. #1 target moves to desired point and stops motor #1(circuit resets till button is pushed again)
4. Stopped #1 target sets 1st time delay to start motor #2 CW (programmable time delay for 0, 1, 2, 3, 4, 5 seconds (UP or forward)).
5. #2 target moves to desired point and stops motor #2 (circuit resets till button is pushed again)
6. Stopped #2 target sets 2nd time on delay to start motor #2 again CCW (Down or reverse). (Programmable delay start time for 0- 15 seconds)
7. Stopped #2 target sets 3rd time on delay to start motor #1 again CCW (Down or reverse). (Programmable delay start time for 0-15 seconds)
8. Object moves to desired point and stops motor. (Circuit resets till button is pushed again)
Where I work I have access to any kind electrical component that has been listed in the thread. I just do not know how to put it all together! With a diagram and known parts and their location I can put the system together.
I can use a PLC pretty well with robotics with these kids, the circuitry is where I lack knowledge.
There is the skinny on what we do and the idea we have.
why we do it.... the kids...
