J-Tech Challenge

Our robot arm project started in 2018. We are now creating small robotic arms as a test project to animate the arms of a teddy bear. Latest Picture The First Version. It used three servos, but it was too noisy. The Second Version.   To reduce noise I tried using stepper motors, but it didn't work well due to heat buildup. After 3 weeks it stopped running so we decided to use servos again. The Third Version (Top Video)  Using five servos. Installation was just about completed, but we discovered that the cable broke after only one day of operation. So now we use strong stainless steel cables. Robot skeleton installation time.

Sometimes elderly people need remote document or digital device support. We came up with a solution that allows someone to render support from afar. Our remote pointing device development is outlined below. In the video, I was in the office, while my son who was at our home received my direction. I asked him to point to several places using the remote pointing device. There was no need to explain how to navigate the device, since he could easily do it via the website I developed. I thought this remote pointing device may help my mother who lives in a retirement home in Japan. For example, she receives a document, in this case a questionnaire letter that requires information to be filled out. To assist her, we ask her to place the letter under the camera, and then we can see the document remotely and explain what needs to be done with the pointer. We look forward to a successful project that is easy to use. We hope to use this technology for other people and companies.

We bought a couple of watch winders, but all of them were noisy and broke easily. So we decided to make a winder utilizing raspberry pi. To start, we tried out the watch winder on a thirty year old watch. Now it winds every seven minutes.

We had a professional 3D printing service print the casing in a material called aluminide for a cleaner finish. The only downside to having things made by a 3D printing service is that, it takes 3 weeks till it arrives in the mail after placing the order.

We're now using NFC technology with our timesheet system! We have implemented the NFC technology into our timesheet system making it easier and simpler for our friends in the office to log in and logout of the system. Using this new system, we no longer have to go on our computer and open the web app to start logging the time anytime, because we can just open our iPhone app and scan the NFC tag on the office entrance on our way in in the morning. The video below is of our NFC implemented system in our office that is already in use.

We decided to add MMCX female connectors to our T5p headphones to allow for easy cable replacement / upgrade with any MMCX male cables. First, remove the original cables. MMCX female connectors  I got these connectors in Japan, but I was able to find them on Google too. Push in the connector into the 3D printed parts. You can download the files for the parts we 3D printed  here . The parts were a perfect fit when printed on our 3D printer, but it may defer depending on the 3D printer. Then I cut the original cable to create two short cables and soldered them onto the connectors. The middle prong is for the red wire, and then as for the outside prongs, you can pick one for the ground. After they're connected, you can secure them in place with some hot glue. In the picture below, the cover parts are put on, but those can not be on when you insert the part into the headphones in the next step. Then insert this part from the outside o
