This is a mouse that I would love to use well into the future, but I don't want that future to include micro-USB. I took apart the mouse to see what I could do to replace the dated port and found that the space was too limited to just slap a different...
The purpose of the project is to design a balancing robot based on the STM32 MCU. On the web, you can find many guidelines on designing the balancing robots. Nevertheless, I always had a hard time finding clear and complete instructions. For example,...
So far, I have cut away the back aly body, and exposed the driver boards, with hardly any damage.It looks like there are a bunch of driver IC's attached to the drivers, under what at first looked like kapton tape, but now appears to be some sort...
Overview My personal goal has been to use this project as a learning platform for myself. So far, I’ve been able to explore all sorts of software and hardware that I hadn’t worked with previously. I’ve been kid-in-a-candy-store, getting to...
I did this project because I was annoyed with having to use my phone while driving to open the gate, which is GSM controlled by calling its number, and takes a while to open, so you really want to call in advance. This way I can just push two buttons.It...
I picked up a vintage HP 1600A/1607A logic analyzer set over the weekend which was state of the art back in 1975. I thought I would see if I could at least get them running and functional and then maybe develop some interesting stunt! I was surprised...
Several years ago, I had to learn how to use National Instruments Circuit Design Suite (Multisim and Ultiboard) to create a circuit schematic and PCB layout for a new job. This was so that I could better understand the software, and help students with...
How It Works I built a quick-and-dirty proof of concept Android messaging app with the help of the MIT App Inventor. This app can receive text messages, and take some actions based upon them. There is a "Make Me Funny" button that feeds the text of...
The VTTC Staccato Controller was developed in the attempt to create longer sparks from VTTCs while at the same time reducing the input power. The Staccato Controller achieves this by operating the VTTC for a full AC half cycle, then disabling...
I wanted to expand this idea to rented farmland. I had several challenges there, such as no Wifi and power. So I had to use LTE and battery power. This project was developed prior to my already posted project of NRF camera project(which is still in development)....

Introduction. If you love DIY electronics, you’ve probably heard about Arduino. It’s a fun and simple way to get into robotics and programming. But did you know you can also use it to send text messages and make phone calls? That’s right! With a little...
Introduction It's the perfect time of year to stay warm and cosy with a hot cup of tea or coffee. However, it's important not to make it too hot as it may burn your mouth. That's why I made a Temperature Monitoring Smart Coaster. This smart coaster can...
Since my workshop is in my basement with no windows, I wanted a way to keep an eye on the outside world. I don't have a ton of wall space (or $$$) to make a fancy fake window, so I opted to use an old eBay PC that I had and a 27" monitor I got...
The MCU is a MSP430G2231 which is extremely small and limited but it comes in a PDIP package and is easy to program (see my last project). It is well suited for this application because I only need 1 shift register, 1 output pin, and a 1 MHz clock...
