Introduction to the World of Oscilloscopes
For a person like me who is interested in electronics, Oscilloscope serves as almost a gateway to heaven which can unravel the deepest ...
The Allure
I have a stereo microscope that is extremely useful, but it is not good at everything.
Specifically:
it isn't any use in a blog where you need viewers to see something with high magnification
it can be fatiguing to hunch over the microsc...
Inspiration A long long time ago, in the early days of my VHDL endeavors, I set out to re-use an analog 20MHz scope that was sitting in a corner of my company's lab as a clock display. Inspired by PicOClock from Bruno Gavand (Oct 2007), I wa...
Back in October 2020 I started a series of blogs on an "Smart Solar Lighting Project". The idea was as follows: Li-Ion charger, with programmable charging current level to find the maximum power point (as opposed to true power po...
Off the shelf and open the storage container.This project is 4-5 years old, it has had many spec changes over the years. It features a Raspberry Pi, a GPIO expander to solderless breadboards, I2C servo hat, and an Arduino Nano wired on the I2C ...
The next update will be the final project completed !! Test code of 5 bytes of data from the Arduino to the Raspberry Pi is working and being melded with functionality for meeting the final project goal + some scope creep that just fit in too well.&n...
Off the shelf Part 3 - Getting the I2C to talk there are several simple examples of Raspberry Pi to Arduino I2C on the webIn studying them, I'd selected on in particular example that was a best fit:demonstrated both data read & writeuse...
Off the shelf Part 2 - Please see part 1 for the hardware overview - I'll sketch up a schematic later, its not complicated, mostly IO on I2C and their 3V power supplies.The DC brushless motor and driver is a touch more involved, but still pretty simp...
Off the shelf, and open the container. This project is 5-6 years old. It features a Raspberry Pi mounted on medium density fiberboard (MDF).The MDF provides a solid base that parts can be screwed down or hot glued, taken apart and reworked multiple t...
I have 48 years old but I never left the passion for RC toys. I have 2 children and I bought RC toys (especially a lot of RC car) for them and for me. Now I have lots of rc cars without remote controls in my garage that are nostalgic, beautiful, vari...
My project is about building a radio signal strength tester for existing signal. So that you can test for superimposition of signal for your own radio project. Background on Radio technology and Some important key points to know :- Radio:-t...
So, I was looking around for a box of incomplete projects and I came across this. A just started (2 years ago) a Raspberry Pi arcade machine. So, I figured why not complete it!! Now go back in time 1 week. Our family’s friend’s...
I had just bought a second hand laptop Samsung Brand with the spaecifications as follows:ntel Core i54Gb RAM with 120 Gg HDD.Unfortunately it has issues, such as:Dead battery but still runs whenever the power charger isconnected and plug in an outlet...
Mounted the controller breakout board (i.e. perf board) and routed the RGBLED OFC cables through cable holders. Cable holders are just pieces of heat shink tubing, super glued to back board. In addition mounted the power supply assembly and routed po...
Day 7 was a revisit to the electronics. The hired help completed the display panel knitting. It is now available to work to start assembly. The upper left corner of the display panel will hold the perfboard/controller. Cables extend out to each ...
Today's blog post focuses on programming. When the project was initially started a draft of Python code to control the LED's was completed. That code had to be abandoned because the controller was changed from a PI to Geekcreit Mega 2560. Bef...

Three days of rain during harvest season has given some farmers reason to return to the model railway layout. With the RGBLED OFC's constructed, I took someone up on the offer to build the display and knit the strands through the holes. {gal...
With an extra pair of hands working on the display panel today's efforts were focused on electronics. Simple setup. Wire RGBLED OFC to limiting resistors and then connect limiting resistors to controller GPIO's. Wire a button...
I started working on the fireworks burst patterns and then ran into a chicken-and-egg paradox. "Chicken-and-egg" is a metaphoric adjective describing situations where it is not clear which of two events started first. What do I need first t...
InspirationThis project started when I was so busy with the daily schedules that I could not give my time to my gardening tasks and all my plants really lacked water and moisture. So I thought Why not just create an automated gardening project so tha...
