Hi all!I am glad that I was selected among the beneficiaries who received the Under Pressure kit", and I will continue to try to put into action every sensor received.A few days ago I received the package with these Bio Sensors, or better said f...
The first two posts are here and here.
Part V: the modules
At last, I had the time to build some modules. An example is depicted below.
The modules were a pain to build because the ambient temperature is so hot these days that the soldering pa...
In this blog post I will describe my project which I have done as part of Project14 | Build Projects Using 7-Segment Displays! Competition. This project I implemented for testing possibility of adjusting output voltage of step-down voltage regulator...
The Pico Parker displays the distance from the Maxbotix ultrasonic transducer to the nearest object in cm - in this case the nearest object will be a car and the distance will be the distance to the end of the garage as it tries to park..

Work From Home Timekeeper
Introduction
From the title, many may have guessed what is the purpose of this timekeeper. The main reason for me to develop this project is to trac...
I made a 3d printed clock researched for stl files to get an idea, first I made one with MDF and a laser cutter but moths later I decided to use a 3d printed model to improve it. I found some files on thingiverse, and used them as a refference, but t...
Over the last few weeks (months maybe?) I've been playing around with 7-segment displays and an old clock display I had in my pile of hoarded things.
My most recent blog post in the series was a throwback to the 1980's: The VCR Emulator
But now here ...
The first season post is here.
Part III: the smart display
Let me introduce you the Smart Display, built on the Stranger Segs platform!
It’s basically an application to display a character from a message transmitted by a driver application (a s...
I know you all secretly miss the 80's, with the big oversized electronics that our parents didn't know how to use.Back then you'd really get something for your money - the cost per pound of electronic equipment was so much better. Today, however, it'...
I've been fiddling around with a 7-segment clock display, which is really just a display that combines 4 different 7-segment displays into one neat little package. With an extra couple of dots thrown in for good measure.
In my previous post, I was ab...
In this first step to building a digital timer, I've set up a clock display with a Raspberry Pi Pico, and then I simply have the Pico step through the 4 clock positions, showing each digit 0 through 9 for each position. At the same time, the div...
Greetings !
I present another project in which I used a 4-digit 7-segment display, but this time it is a common cathode with 12 pins, red color.It is a settable clock, but the idea is more about the pleasure of making a PCB, so you can share your opi...
I recently came across the online circuit simulator Wokwi. So, I don't really know what to say just yet. But, I am certainly impressed to say the least. I copied my RPI Pico 7-segment design into the simulator and it ran just fine.
Pretty incredible...
I purchased some LED filaments a while back off of AliExpress for a project after learning they are available with 3V forward voltage. They looked like they would also work for making DIY 7-Segment displays.
You will have seen them used i...
Introduction
Inspired by the Pi Pico with 7-segment display blog, written by ntewinkel, I decided to give it a go as I had a 4-digit 7-segment display in box that had never been used before.
Little did I realise what's involved to get ...
Moving forward one more step towards some mysterious 7-segment display goal I have in mind, tonight I was testing the clock display I had.
For those paying veeeeerrry careful attention, this clock display might look familiar - I used it in a project ...
As I mentioned in my previous blog post, Pi Pico with 7-segment display, I decided to try using a 74LS47 chip to handle the logic of converting a number in code into a 7-segment digit.
Newark Canada sells these chips. I think the 2 types might give ...
You know how sometimes you build things that are so impressive you just have to share it with the world?
This is not one of those times but I'll share it anyway.
I did have a fun project remake in mind, and this would be step 1 in that pr...
I made this health kiosk using Arduino uno, raspberry pi and lcd
It features temperature detection, voice based kiosk
OTA firmware update
Planning to add some more features
I can remember building an electronic die soldering kit as a child. I haven't seen that kit in ages, I assume its gone for good. But I can try to build a new one with a RPI Pico...
If you look at the dot pattern on the faces of a six sided die, ...
We all like LEDs, simple LEDs, or LED displays, such as those 7-segment, 4-digit displays. I use them more with Arduino platforms, they are useful and also more visible than other types of displays. In order to be able to use a 4-digit, 7-segment dis...
The following example of 7 segment display is implemented in an FPGA by hardware/software co-design. The video shows that the system has an ascend/descent control and reset button.
