I used the wire I mentioned previously and fixed the Bluetooth connection with Misty. I talked to the misty team back and forth. They told me that the software was in misty. I used the app to find the IP address then used the website and I was able to do simple controls. I tried uploading a skill but it did not work.

In the past 5 days, I found a wire in the lab that was a perfect fit for an old project. the old protect in a Misty robot. I got the robot working but the person who gifted it to us did not give us the software. I called the company and they are going to send me an email soon. For prosthetics, I wired a butter to a beeper and am going to try to make it with a vibration motor. Also instead of a button I want to add a pressure sensor so the more force applied by the finger the vibrations will get stronger.

I printed the finger about 4 times but it is too brittle and breaks every time I try to tap and die it. It is printing in tpu now. I need to order smaller screws. The Arduino Nano is busted so I need to solder all the connections to the smaller board. first I need to figure out a new sensor. the current sensor only works on skin and some metals. I will first get a vibration motor working with Arduino Uno before moving to the Nano. I am going to buy a cheap watch and strip it. I want to fit a vibration motor, Arduino Nano, and a battery in the watch face. I might need a big watch like those Army ones. I only want one reinforced wire leading to the sensor from the watch.

l have printed a new finger from the web. I explored touch sensors and used an Arduino and used code from the web. The code works and turned a light on. I want to experiment with a motor or something that can vibrate to indicate touch. I tried to extend the sensor but the weirs broke. I plan to print a carbon fiber and use small bolts and maybe bearings I want to also want to make the link from metal.

3D print for the finger was developed by a man named Nick who has a website called Nick’s Prosthetic Finger.  the finger he developed  required the user to have one digit of their finger left and a string or piece of fishing line would go around a bracelet and when the user moved their nug it would potential on the string moving the rest of the finger. his latest version is 3.5 but he is coming out with version 4 soon. I use this concept but instead of being based on the movement by your other finger it would be based on the movement of the server motor that would contract the finger. this is a good alternative because many people that lose their fingers lose an entire finger not just one or two digits. the best and mostly prosthetic thing or Electronics. For example all of Naked Prosthetics’ fingers in addition to Nick's 3D printed prosthetic finger. the best fingers are made by Naked Prosthetics in my opinion, but I know they're expensive because instead of playing a price says get a quote. in an Ideal World There would be an option for people that lost their entire finger that was non electronic but right now that doesn't exist. with the most control fingers I hope to have a good alternative for finger amputees that won't break the bank, be comfortable, or be too bulky.I'm looking to see if there are any that I can work with because many of them have different opinions on Prosthetics. some see it as I still have four other working fingers so I don't need it. these people are often older because they do not have access to good Prosthetics when they were first amputated. many newer amputees are looking for a prosthetic to replace the finger they recently lost. in my opinion one of the best things a finger amputee can do is get a prosthetic early so they can be retrained with it, especially if they are a kid. 

I am looking at the most common types of amputation and Naked Prosthetics. They are the leading industry in mechanical fingers for partial finger amputees.


I haven’t updated my WJ in a while since then I have helped with WILD and made my poster. I worked on taxidermy. I was not too fond of it because of how the fabric looked. I helped with Hydroponics

the prosthetic finger is now muscle controlled using EMG sensors. the sensors go on your forearm and back your hand. to get best results find where your forearm flexes the most and put two on one closer to the wrist and one three inches behind it. connect those two to the red wires. the black wire or the negative wire goes on the back your hand in the center. these were hooked up to an Arduino Uno with a backyard brains attachment for muscle control. I used code from backyard brains for a muscle controlled claw and slightly edited it to fit the finger. the finger right now is glued to the model along with the servo motor. I'm going to figure out soon how to mount it to an actual hand and have it be removable. to power the servo and Arduino and sensors you need two 9 volt batteries, one plugged in to the Arduino and one plugged into the add-on. something you can do to help with the sensitivity of the sensors is wrap the wires in electrical tape. insulating the wires will not let the electricity from your fingers affect the finger when you grab the wires. To change the sensitivity and twitchiness of Servo motor I messed around with two different things in the code. the first thing Was the update time and the second was the minimal step. if the update time was too long the finger wouldn't be practical and there would be a long delay. if it was too short the finger would be updating constantly and in some situations it would read your heartbeat and move to that. the minimal step was the minimal degrees it would turn. in other words it would update every that many degrees. A high minimal step would make the motor slow and only go to the up or down positions. But a low minimal step would not let the finger move down for some reason. I am still trying to figure out why. Trying to find a way where I can have the finger in a position that is not just up or down and be able to hold it in the middle. to do that I'm messing around with the sensitivity in the code stated before.


Over the last 2 weeks I
-Found the pre-sliced files for Goodboy

-I found the code for Goodboy

-Brainstorming a name; probably Rex?

I also ordered the parts. They were sensors and a charger. The 3D print however made these filenment lines and looked bad. It’s on the inside so you can’t see it because it’s on the inside. The filament was likely a problem so Megan suggested a standard time.

In my first week of WISRD the week of August 27th, I helped a peer with his robotic arm.  The arm was interesting and I admire the student leading that because he is always positive even when something goes wrong. That week I started to get the CNC machine working again the laser cutter had stolen the spotlight. after getting the CNC running the PC will not load. I am going to try another PC. In addition, I am trying to find the best CNC software. after looking at the prosthetics and robotics projects I realized being able to work an Arduino board would be extremely useful so I started to try to get a Servo Motor working. I am having so much fun.

2023 Statement of interest: I hope to have a creative output for the scientific stuff I have in my head. I am interested in joining because I admire the free flow that WISRD gives. I have already worked with prosthetics. I find studying anything greatly interesting except for space. I am also happy to help with other projects that other students may be working on. I hope to gain real-world experience working in a lab
