Re: Remote Weather Station

While I started designing up a 10cm x 10cm cheap Beta version with some weather station sensors and a STM32L151RE MCU, I quickly hit the silicon shortage snag and found that if you can find MCUs, prices have gone through the roof. A MCU I purchased back in 2019, is now five times the price. I now ha...

Remote Weather Station

What does the words: Remote Weather Station conjure up in your mind? In mine, it's a weather station way out off the main road on the Nullarbor desert. This will be a many phased project - each phase building on the previous one as I learn and experiment along the way. Something like this: Beta: jus...

Re: Visiting Four out of Five Adelaide Makerspaces

While not Makerspaces, I did visit the Goolwa and Victor Harbor Libraries. These both hosted 3D printers from which the public could come in and print out things they had designed or downloaded from the Internet. This is the Goolwa Library printer: Goolwa.jpg The Victor Harbor Libraries has a volunt...

Visiting Four out of Five Adelaide Makerspaces

Re: Universal e-Paper Name Badge

Today I upload the next PCB revision design to JLCPCB to manufacture. This will fix a couple of wiring issues and will include a MPU-6050 accelerometer, so the board will be able to rotate the text depending on which way your mounting the unit. I am also trialling a ESP32-C3 MCU. This is being bille...

Exploring Ideal Diodes

I have used some Ideal Diode circuits in a few projects now, but have found that they leak a reverse voltage back through the Diode (MOSFET). Scouring the Internet, I have found three different designs all based around the idea of turning off a MOSFET if there is no voltage on one side of the MOSFET...

Re: Throttle Boddy Driver

Love the GIF! How are you driving the flap position? If it's a variable resistor, or an encoder, have you looked at the values to see if there is an instability/fluctuation in the incoming data? Maybe displaying the data in the Arduino Serial plotter might help to make sure it's linear?

i2C Rotery Encoder

I saw these nice looking i2C based rotary encoders on Adafruit: https://www.adafruit.com/product/4964 and thought it might be fun to make one based around a ESP32-Pico MCU. This MCU includes a crystal built into it and some flash memory. I am not using the WiFi section for this project. It is progra...

Universal e-Paper Name Badge

I have been fascinated by e-Paper since the technology was announced long time ago now. Back in 2017 a few of us did a group buy and purchased some black and white and a tri-coloured black/white and red e-Paper displays. These worked with the Waveshare ESP8266 and ESP32 universal e-Paper controllers...

Creating a KiCAD Plugin - Auto Export Front Paste Layer

I laser cut my own plastic stencils at home. To make it easier to export the KiCAD Front Paste layer, I created a KiCAD V5.1 plug-in. This might need to be re-written for KiCAD V6? It took a bit or experimenting to figure out and mine was based on this sites: http://scottbezek.blogspot.com/2016/04/s...

Re: SOT-23 breakout PCB

This PCB has been superseded by a PCB that incorporates a DFN1006 and SOT-23 footprint breakout: viewtopic.php?f=9&t=2461#p3784 AND more importantly - space to write the name of MOSFET that's been soldered into place!

Re: DFN1006-3 SMD Breakout PCB

With feedback from my SOT-23 breakout PCB, in that I need a space to write on the breakout PCB what MOSFET is soldered into place, I redesigned the PCB for a small 3mm x 9mm blank area. I then realised I could incorporate a SOT-23 mounting pads as well. This now gives me a 2 in 1 breakout PCB - bonu...

Re: Acrylic Display Sign

The blue acrylic sign PCB works really well and I am very happy with it. It is however around 44mm wide, so it won't fit into the initial MDF housing I made, so I designed up a new wider and a bit taller housing. It's made from stacked up layers of MDF and included provision of a USB Micro extension...
