Taking an inventory of electronics for the controls, calculating current expenses, look at the CEB's and determine a work area.
Laying out controller box. Using a Pelican 1060 box with a clear lid so we can see the LED's on the boards. This isn't a finished design, merely for observation while tweaking the over all design. Will also see if we can have a 3D printed scaffold of sorts for the components to screw into as space is very limited and I must suspend the components.

Drove from Austin to Factor e Farm, 12+ hour journey.
Tuesday Aug 13, 2013
Went to Fry's Electronics in Austin to acquire parts for the controller. Picked up a crimp tool for the Molex connectors, some 2, and 6 pin Molex connectors, 3-1k ohm linear potentiometers, a rubber boot for a toggle switch and some extra screw down terminals.

Ordering parts and finding alternative sites. Working with Katie on this.
Thu Aug 8, 2013
Work log at bottom of page.
Finalizing parts needed for initial controller build.
Wed August 7 2013
- Upverter - Google Doc for circuit design - free for open source project - Link to Schematic:
- Conference call with Zach.
- worked out a BOM for the controller
- have a schematic drawn for the circuit
- will compile the BOM tomorrow to get parts ordered.
- Amazon BOM
- Future pressure sensor - continuous vs on/off - [1]

PCB Design
- See CEB_Press/Manufacturing_Instructions/Detroit_Fab_Lab_Solenoid_Driver_v4
- See code - [2] - updated July 2013
- Design software runs in Wine on Ubuntu - [3]
- Arduino - [4]
- Cable - [5]
- Relay - [6]
- 12V to 5V supply - [7]
- Buttons - [8]
- Code for Diecimila to Teensy - [9] - convert Diecimila to Teensy
- Real Terminals - [10]
- Or Yoonseo Terminal - [11]
Design Rationale for Zach's CEB Controller -
- Switch from automatic to manual mode - toggle
- For drawer - you calibrate it and move it a certain percentage.
- For drawer - end positions via pressure sensor
- Replace pause with auto/manual switch
PCB of Board - [12]
![[12]](https://github.com/OSE/ceb-controller/blob/master/dwielcode/board/cebpress-controller-schematic-v4.png){kind=link}
- Design Have plugin into main board
- Uses Arduino Teensy
- 6 buttons - forward back up down pause shaker; timing knobs - 1 for main cylinder - to select brick thickness based on a given power source; 1 for drawer cylinder

PCB designs
Sitting down and looking into PCB design for the CEB's. These will be professionally made to save time and also designed to be robust enough for outdoor, all weather use.

Log Start
- Evaluate current requests from FeF and determine cost, time, and workflow
- Setup Log
Had a late day getting started as there were unexpected issues here in moving my truck from Creation Flame to a shop in town. This will become 1983 Chevy Blazer 6.2 diesel mobile 4x4 power cube with a turbo. :)
