Modified Hello Echo – Part II: Hello Echo + Button + FTDI

Modified Echo Version 2 – In Production

I am having some issues with the Modela this week. I milled this board last night, but it came out hairy / torn up. I will give it another go tonight.

The Mantis Hardware + Software Trial Run

After we put the spindle together – Shawn and I tested the Mantis to see if it would respond to commands. It looks like Fab Academy AS220 (with a huge effort on Noah’s part) put machine together properly.

The Mantis responded to the following commands (see screenshots) and responded well. The next step is to figure out how to feed an .rml file into the software. (in progress). After that we need to mill a board on the Mantis and see how it turns out.

Modified Hello Echo – Part I: Hello Echo + Button + FTDI

Modified Echo Version 1 – Complete But Broken

This version milled out a bit hairy. Some of the traces were broken, so I used jumpers to re-connect them.

Modified Hello Echo + FTDI + Button  v.1

There must have been a short somewhere – after stuffing it, setting the fuses and flashing it, I plugged it in to a 9v battery and received a puff of smoke for my efforts. The LED went on – then smoke came out.

Modified Hello Echo + FTDI + Button v.1

In addition, I placed the button too close to the programming header, making it hard to press the button. I am not including the Eagle board or schematic here – see version 2 for a better board.

Back to Eagle!!! See version 2 for a (hopefully) improved and working board).

First 3D Scans – Modela Scan of Laughing Die and Shell

The Fab Academy Assignment
The assignment was to scan an object. I used the scanning attachment for the Modela milling machine and the Dr. Picza 3 software that comes with the Modela.  The Dr. Picza software works well enough, but unfortunately, it only runs on Windows.

The yellow Modela attachment (see pictures below) taps around the surface of an object using a touch sensor in order to scan a representation of it into the computer.

The objects I scanned were one of Shawn Wallace’s “laughing” dice and a shell we had laying around the lab. The output was saved as screenshots and as an .stl file that can be imported into meshlab and then cleaned up and (hopefully) printed with the Makerbot Cupcake CNC printer.
