It’s exciting to be able to offer classes again, even though with a reduced size and constraints due to Covid. Introduction to 3D Printing will be offered on January 23rd at 1 pm and our popular Introduction to Laser Cutting/Engraving on February 20th. We’re hoping there’s also interest in some micro:bit classes, refer to our classes page for more information.
We’ve continued to experiment, a lot, with the micro:bit since giving them away to youth in the fall of 2019. The micro:bit capability is still impressive for a device that size. In the window of our Franklin Street location you can see several micro:bit projects, including some that have been written about before.
One of the more mysterious window projects uses the micro:bit’s internal bluetooth radio. There’s been a micro:bit for some time that sends scrolling text and can control a string of lights and a rather loud alarm bell if the right text is sent wirelessly from another micro:bit to the window unit.
Hint: the words to send are obvious, it’s easy to program in MakeCode, and use Radio Set Group 1. It even works from outside! I’ll link later to some more detailed additional help.
We’ve still had projects at Castlemakers this summer, even with the Covid shutdown hampering our hands-on education efforts. One that I’m excited/impressed with is a high school student built project that includes programming, electronics, 3D printing and using a laser cutter – all made with items at the Makerspace!
Ever since we gave every 6th grader in Putnam County a micro:bit last year, we’ve wanted to do more micro:bit projects to help youth and adults see the power of microprocessors and IoT devices. And to get a chance to expose and use some of the some different fabrication tools often found in a makerspace. This summer Hunter Miller made a really interesting project, an edge lit sign controlled by a micro:bit. It looks a bit like an emergency exit sign with a disco like effect and instead our logo on it.
The design and case was modified from something created at the Cambridge UK makerspace, who was looking to create something to experience the different makerspace tools. We used our 50W CO2 laser to cut and etch an insert for a 3D printed case that with led lighting on the edge makes our logo stand out. Hunter, who was looking for something else to do this summer, then cut a section of a 2m LED strip and after some soldering connected the wires directly to a micro:bit. Then he wrote a micro:bit program using MakeCode that makes the LED strip change color and intensity.
It’s on display right now in our front window on Franklin St. Stop by and take a look or come in and we’ll show you how it works – the different lighting modes may have you dancing!
The PCMI started in 2018 from internal discussions about the technology gap in rural communities and how to get more folks interested in technology and coding, especially youth. PCMI was born after seeing a demo of the BBC micro:bit at the 2018 Hackathon in Indy – it seemed like a potential solution! Thought why not put a simple-to-use single board computer, in this case a micro:bit, into the hands of Putnam County youth so they could learn and use them?
After researching the micro:bit further and writing a Techpoint Foundation for Youth grant to get 10 for first hand experience in our CoderDojo, we decided to use a variation of what was done in the United Kingdom. We would give them directly to all 6th graders in Putnam County. The device is already being used in some US school systems, including NYC’s Computer Science for All and some Project Lead the Way classes, but with Indiana’s computer science curriculum under revision we were hoping for a quicker jump start so folks could recognize the significance of physical computing and that it doesn’t have to be difficult!
Luckily for us the Putnam County Community Foundation understood the importance and was willing to fund our idea. All four school systems were also willing to help – so we’ve been rolling out micro:bit kits to the 6th graders in Putnam County during October. Our last distribution, to home school kids at Putnam County Public Library, is on 11/4 and we’ll also be having a community session for parents and anyone else interested at Ivy Tech Community College in Greencastle on Monday November 4th at 6:30 pm. Seeing the excitement of the 6th graders getting and exploring their devices has been a real treat!
