Log from Bunny Jump - Severe Jeans
Throughout these days, we worked on finalizing our code and finalizing our box. The only errors that had occured throughout these days was 2 of our wires breaking the day of delivery day, but we fixed that by editing our code. We also fixed the...

Log from linear actuations for everyone!
This time I faced with another sort of problem. I've decided to install smaller capacitor to check if it has anything to do with efficiency, I was interested to get significant voltage increase on capacitor during charging cycle, and I've got it ;DEnergy...

September 28th 2023: I can't make the linear actuator move precisely
Log from Automatic Moving Cricket Wicket
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...

First build-day. Have been planning for a while, but now it is time to try my ideas.Connected an i2c 24c02 EEPROM, using A0 as a chip select. Found out that the address is actually NOT based only on A0-A2, but also a hard-coded chip-type specific "magic...

Batch of 20 prototypes
Log from Plobot
We agreed to run a summer camp with Plobot. That means a lot of kids playing with them at the same time. We ended up adding two layers of acrylic below the encoders in order for them to stand still. Things like that and cutting the terminals of the battery...

Log from Web Enabled Microscope
Well that is embarrassing, I made a huge error on the positioning of the focus knobs of the microscope so the models I made yesterday are invalid. PSA: Measure twice! Or at least take a look at the model and see if it makes sense!I did print the bracket...

Pimped 20-channel PCB
Log from Servo Breakout for WeMos D1 Mini
OK, the one-sided board experiment was fun, but not very practical. Especially since all the fab houses out there make two-sided boards by default, so I don't save anything. So I went back to the two-sided board, applied some of the improvements I discovered...

Log from ARX Hand Project X1M
MK0M has been updated to suit either 2.85mm or 3mm diameter filament. They will allow either compatibility depending on availability of materials that can be sourced locally. Nylon is still the recommended material of choice for its durability, flexibility,...

Log from Halloween Candy Mortar
Web page controlled Launch Sign: Used an ESP32, 6 LEDs, and a usb battery for the circuit. Code is from Random Nerd Tutorials (ESP32 Web Sever). Built a simple sign from a polycarbonate sheet and some pieces of wood. Hot glued the LEDs under the...

Log from Mood Gradient
We used the same cardboard technique as before to confirm that the dimensions for our remote controller box are good. Our remote controller fit perfectly into the small box, so we are ready to move on to printing the final designs of our boxes. Today,...

Log from Little Monster
Ok, we have some problems. The school printers being taken, we asked someone to print the parts for us. After some problems, especially related to the axes because too small, we finally have our parts. However, the holes are too small to fit the axles....

Log from AquaPic - Aquarium Controller
This blog post is going to be a bit scattered. At this moment, I have a lot of projects at the 80% or a little more done, but nothing complete finished. I have been putting off any sort of update because I've been waiting to at least finish one or two...

Around 20 fps
Log from PolaPi-Zero
I figure out how to reach a better frame-rate on the LCD screen. On possibility I didn't tested is to grab the video frames frome the picamera library. I had doubt the RPi zero can transform fast enough the image but it's doing well at 20 fps. There...

8-20-14 LEDs
Log from Wi-Fi Controlled Open Scoreboard
Just doing some quick math to see the current requirements of the LED display. The LED strips I have are made for 12v and have a built in resistor. They are separated into groups of 3 serial connected LEDs with the strip itself all in parallel. There...
