When
• October 4, starting at 7:30 PM Dallas time (CDT).
• Robot Builders Night Virtual (RBNV) meets each Tuesday evening.
• Talk robots & related stuff.
• Make it easier for people to attend DPRG remotely.
Agenda
• Round table – everybody spends a couple minutes telling what projects they’re working on.
• Ad-hoc presentations – Whoever would like to show & tell.
• “Stump the club” Challenges – Ask for help if you’ve hit a roadblock in your project. Somebody in the club can probably get you pointed in a good direction – or even arrange a side bar session to help.

One vulnerability of the Raspberry Pi is its susceptibility to micro-SD card corruption. Power interruption during a SD card write is the main culprit. Such interruptions can corrupt the file or even make the entire micro-SD card unusable. The problem is worst in designs where the Raspberry Pi runs headless, leaving no convenient way to request a graceful shutdown.
The Solution:
The solution consists of four parts: a Python script, a service, a shell script and a switch. The code and installation instructions are at https://github.com/zizumara/GPIOshutdown.
How it works:
The GPIOshutdown Python script, when run as a service, provides a way to initiate a graceful shutdown of the operating system by grounding one of its GPIO pins through a switch. The script monitors pin #26 by default. The value of SHUTDOWN_PIN in GPIOshutdown.py controls the monitored pin. When launched, the script will wait for a fixed period before beginning to monitor the GPIO pin. This is a failsafe to allow the user to login via SSH and stop the service to prevent continuous rebooting if the GPIO pin is damaged or otherwise accidentally shorted. The delay defaults to 180 seconds but is modifiable by editing the value of ARMING_DELAY in GPIOshutdown.py. Marking the switch to indicate which position initiates shutdown is highly recommended. In this application, shutdown occurs when the switch is closed.

On August 27th, DPRG will descend virtually on the Seattle Robotics Society ROBOTHON Exhibition. Members and guests (everyone is welcome) will gather in the Dallas Makerspace’s Lecture Hall for a joint live viewing of the third SRS Virtual Robothon. Members are also encouraged to use this gathering as a swap meet for robotic components that they wish to make available to others.
SRS video of event:
note: DPRG’s Doug Dodgen’s presentation starts at 1:27:17
When:
August 27, 2022
2:00 to 5:00 PM CDT
Where:
Dallas Makerspace – Lecture Hall
1825 Monetary Ln, Suite 104 · Carrollton, TX
Event:
The SRS Virtual Robothon event is designed to be a “free-style” show-n-tell type showcase. Ideal project categories are: any type of robot build, contest specific robot build OR a general robotics related project.
This year’s Robothon lineup includes DPRG’s very own Doug Dodgen:
Dan Royer – Machine Learning dog walk in Unity
Jim Kinsvater – Rover Robot
Steven Kaehler – Building and Programming Makeblock Robots
Chas Ihler – 5
Donna Smith – My Outdoor Rover Build
John Jennings – The “Pop-Can” Robot
Doug Dodgen – Function Prototype of a Telepresence Robot
About Seattle Robotics Society
The Seattle Robotics Society was formed in 1982 to serve those interested in building robots and associated technologies. We are a non-profit corporation consisting of a diverse group of technologists and tinkerers. Our collective passion is learning about robots through education and freely sharing our skills and knowledge with our community through meetings, workshops, contests, outreach events, online, and mentoring.
