Senior Design Project - Post 4.

I finished connecting the servos to the fishing lines, connected the servos to the power module, and tested the code to open and close every finger in sequence.

Last night I finished printing all the parts for the InMoov hand and forearm. Today I spent a few hours assembling it.

Tomorrow I'll try to add the pulleys to the servos and tie the fishing lines to the pulleys.

Senior Design Project - Post 2.

Last Friday we did our proposal presentation and I think I did well. We were told that our presentation was really good, but a little bit short. We still have not got our grade or feedback, but should be getting those next week.

Last night I finished assembling the InMoov finger starter and tested it with the MyoWare muscle sensor. It took me a few hours to get the code right, but I got it working, as seen in the video below.

A problem I encountered was that testing the finger while connected to my laptop would shut my laptop off. I have to look up what might be the cause, but I think it may have to do with the servo drawing too much current.

Senior Design Project - Post 1.

Today morning I finished writing the report for my Senior Design Proposal. We have just a week before the presentation. I'm a little nervous, but I'm confident that I will do great.

After we do our presentation we'll start working on building the project. I already have an Arduino and four of the five servos we'll need and I have a basic code to control the five servos. We'll first start working on modeling the hand and assembling it. I believe it'll be better to do one finger first, with housing for one of the servos and test its functioning.

Working circuit.

Today I received the new Nixies from Romania and dropped everything I was doing to solder them to the board.

 Such beauty. Much tech. So Soviet. wow

Putting the leads through the board wasn't as easy as I hoped, but it was definitely easier than with diminute leads.

My right hand was trembling after finishing soldering nonstop all the tubes.

Connecting both boards. Here goes nothing...

And it works! I was half-expecting some error code, or it not working at all. But it did.

The Steins;Gate wordline in the divergence mode

The "wordline change" effect every 30 seconds is used to prevent cathode poisoning.

The Divergence mode, with different timelines from the anime and the visual novels.

Now there is only the aluminum case that needs to be done, and my first divergence meter will be finished!

In the meantime I'll use my circuit board holder as a stand.

Dummy board and Nixies

After getting all the dummy parts and the bass wood, I finished the perfboard, glued all the components and the wood spacers, I glued the perfboard to the Nixie board and tried to solder the tubes.

However, the leads of the tubes are too short, and I could only manage to solder one, and barely. I'll have to get  more tubes in order to finish the project.

Note that I only soldered a few joints just to hold the Nixie in place.

Finishing soldering and more drilling.

After receiving all the components, I finished soldering the main board.

Drilling the perfboard with the step drill bit proved to be more challenging than I expected, and ended up having misaligned holes. A couple of days after, I got the Fostner bit and drilled the holes easily.

Now I'm currently gluing  the dummy components to the perfboard. I need to get some blue resistors, capacitors in the correct form factor, and wooden spacers to glue the perfboard to the IN-14 board and finally put everything together.
