051 Implementing a Shortest Path Algorithm (Dijkstra) For Auto Routing the Robots
While part of the original concept, Auto Routing was removed based on a misunderstanding. It is being re-implemented into the experiment as it will add so much more capability.
As the experiment runs, each robot (Zoomie) will be dispatched at random times to random locations. That dispatch message will contain the driving directions to get to the destination. In navigation systems, shortest path algorithms perform this task. Their purpose is very specific, to find the shortest path from all available options to get from start to finish.
Initially it was believed that this would create a bad data set as all robots would pass through the city center thus clogging up those streets. However, as one of our viewers pointed out, the data set can be used to modify the behavior of the algorithm so that it AVOIDS the city center and instead uses the bypass "highway". While not shorter, it ultimately is faster because there is far less stop-and-go situations and less traffic creating additional delays.
This video is not an explanation of how this particular (Dijkstra) function works, rather it is about its implementation in this experiment and later on how it will be used to alter the flow of traffic through ZoomTown.
USB Cable For Raspberry Pi PICOs That Are Self Powered
Many of your PICO projects will be self powered and you need a special USB cable to communicated with it otherwise you can damage the PICO or the batteries. Connecting USB while the PICO is powered can also create a safety hazard!.
This video explain why this is a problem and how to take an ordinary and inexpensive cable and make is safe for use.
BE SURE TO HAVE THE USB CABLE UNPLUGGED WHEN MAKING THIS MODIFICATION!
After fighting my old crimping tool for Dupont connectors, I found a better tool
There are a lot of Dupont crimping tools to choose from, some sold for Dupont connectors are not even the correct type! Frustrated with my old crimper, I went hunting for a better one and found these. So far it looks like it was a good purchase and I am already getting MUCH BETTER crimps.
The Vintage Computer Festival Should be on your MUST DO LIST!
If you have any interest at all about computers and especially their history, you owe it to yourself to visit one of the Vintage Computer Festival shows. This gathering, organized by the Vintage Computer Federation, is an amazing event where you can buy and sell old computers, but more importantly, you can see and in many cases play with computers dating back to the 60s.
Cheers!

About Making Stuff With Chris DeHut
About 20 years ago I produced a Woodworking Magazine that was distributed on DVD and contained Video content. The format was very much like a television show with stories on various subjects. That magazine ran for 3 years. I have revived that content and put it on YouTube to share with anyone who is interested. That was the genesis of this YouTube channel.
Now Covering Many More Subjects
Current video production covers the following subjects:
- Raspberry Pi PICO microcontroller
- CNC Machines (building & using)
- Computers (mostly Raspberry PI)
- Programming in Python and MicroPython
- General electronics
- Robotics
- 3D Printing
- and much more!
