Large enclosure temporarily attached to electronics board so that I can drill holes to join the top plate accurately. Clecos really help.
This is what I plan to build in order to house all the electronics. There are three temperature controllers, an LCD, and a keypad for input. I plan on customizing the buttons to be more useful like arrows instead of numbers. There will be a high current relay inside which will toggle off and cut power to the whole system when temperatures exceed operational parameters. This way I am less likely to burn down my house. :)
4-H Clover College is a four-day series of hands-on workshops for youth presented by Nebraska Extension in Lancaster County. Emphasis is on science, agricultural literacy, healthy living, career development and citizenship/leadership. Many of the projects made during the sessions are eligible to be exhibited at the Lancaster County Super Fair in July.
2022 Clover College featured 54 workshops with a total 926 session registrations. New workshops this year included: “Slime, Jelly Worms & Twizzlers,” “TEC Box - Tinker, Explore, Create,” “Pollinator Party,” “Folk Art Watercolor Art,” “Focus on Photography,” “Hydro-Dip Painting” and “A-maize-ing Corn.”
In Lancaster County, the 4-H youth development program is a partnership between Nebraska Extension and the Lancaster County government. Learn more about Lancaster County 4-H at lancaster.unl.edu/4h.
The TechZone motherboard. (v1.2).
The red and black wires tucked below the motherboard are power for the stepper controllers which are not pictured here (they are off the bottom of this image). I will eventually route the power wires under the thick sheet after I confirm that the electronics work.
This was my second project for my Intro. to Digital Systems. It doesn't really do much but I added a little display to my project, it was just my little touch. For the most part everyone else just displayed the state using two LEDs in binary. I found these cool little flat LEDs on a Yellow Tale Wine magazine ad so I adhered them behind each of the state representations. So the current state is illuminated in the diagram when the device is in that state.
work in progress:
paper, block prints, wood box, self-flashing fast rgb LEDs, diffuse slow fade rgb LEDs, light gels, Japanese washi, Thai handmade paper, switch, and 9V battery, nails, bookboard, brad, stapples, glue
I managed a stall showing off the Raspberry Pi, Arduino and Shrimping kits to the teachers, students and general public.
My 14 yr old son loves to experiment with electronics.
He created this "School-o-meter" to show whether he has a delay /cancellation due to snow.
The School-o-meter" communicates with the school's website and when a delay or cancellation is posted, the paperclip pointer moves to the 1hr delay, 2hr delay, or no school position.
Now, he doesn't have to get out of bed to find out if school is canceled!
He explains it on his blog:

This is a highly delicate operation. For the initial drilling, use a bit you don't care much for, and absolutely do not use one with a pilot tip. The plastic is about 1/8" thick, and it transitions to either space or to another type of plastic which is filled into the screw's recesses.
Removal of the inner plug can be easily done with a "tiny" size electronics flathead. I honed mine to be a very small chisel/knife, and that worked exceptionally well. With that approach, I found I could "pop" out the inner plastic filling with one motion.
If you miss the mark on the screw and accidentally drill too far, just keep going until the entire head of the screw has been drilled out.
