Wrap up 5/8

Troubleshooting, Troubleshooting, and more troubleshooting, all this week we've ran a series of diagnostic tests. We called Techno FMS support and they led us in the right direction, we isolated several circuits to try and identify the problem. We're making progress but we're not there yet.

Week of 5/4

This week we are changing all our attention on getting our CNC Mill completely functionally and operational. This involves changing, upgrading and formatting old computers, our goal is to make it as the mill was brand new and off the lot.

This Weeks Goals:

• Change old computers
• Upgrade ram in new computers
• Install Windows 7
• Install Drivers/mill software
  
  
  
  

5/1 Wrap up for the week

After working on making the part, we had a few successful models. The models worked better then we thought they would holding more, and working correctly when put to the test. These models also helped us find the correct settings for the 3d printer temperature for good stick and crisp lines throughout.

4/27 Week Begins

This week we worked on making a new product using the 3D printer and solid works. After learning how to use solid works I thought it was a good time to put it to the test. This is what we have so far...

4/24 Wrap Up

This week we finished working on our senior project and the board. We finalized the water bus and got ready to take it all to symposium.

Monday 4/20

This week we will redo poorly made/old connections from previous years as well as organize or tool boxes are add a locking mechanism.

            We will also work on...

• Creating/remaking our accessory circuit wiring
• Experimenting/researching on new solar cells

Monday 2/6

This week we will continue to work on our programming ability and work on a soil monitor for horticulture next door.

We will develop the soil monitor in stages first we will have the LCD screen read out the raw numerical valve from the Arduino Serial monitor
Once we accomplish that we will create value ranges and have the LCD screen display the soil condition: Dry, Moist, or Soaked
Then Once that is accomplished we will equip the Arduino with an LED and have it light the LED while it's dry.

Friday 1/30

This week we have rearranged the back area of the Tech lab to make it look more appealing for the open house which was on the 26th, we've also received some new woodworking machinery from a private donation.

1/26 Monday post

Today is magnet open house and it's crunch time to get the room cleaned!
All work has halted as we are preparing to recruit the incoming freshmen and must make this place look it's best.

Once we finish the open house we will be refocusing on digital readouts for the solar car using an Arduino Microcontroller.

Checking out the water bus

Today I looked at the water bus to see how we can fix it up
