converting an old plotter into a camera slide

The author took and old plotter and make a motorized camera slide out of it. Nice build, only issue I can see is its a “short” slide. https://hackaday.com/2022/04/07/turning-old-plotter-parts-into-a-smooth-camera-slider/

Building a simple water sensor for Arduino

Should work with other controllers, basically you have a resistor in a circuit, and if it gets wet, the circuit is shorted out so you detect that. I put 2 wires in a sponge myself (separated) an when the sponge … Continue reading

A drawbot that can use a multi color pen

Interesting build for a drawbot, it uses a multicolored pen to switch colors, instead of changing the “pen” for each color. https://www.instructables.com/Multicolor-DrawBot/

Big 7 segment display

Need to make your own scoreboard, this is a nice build to start from, the large display uses an arduino to control it and the 2 digit display the author made was for timing swim trials. https://hackaday.com/2022/07/27/you-can-build-a-giant-7-segment-display-of-your-very-own/

Me…I am on the fence on this, the look is cool, but I can’t justify the cost even with building my own. https://www.instructables.com/LED-Light-Panels/

Add a kill count to a flyswatter

I got a kick out of this one, the author added a kill count to a electric fly swatter to get a count of how many bugs he got.  This project uses an arduino under the hood. https://www.instructables.com/Ultimate-Mosquito-Swatter-Mod-for-Gamer-Add-Kill-C/ https://youtu.be/_ZuR5MYr-M4

Making your own lie detector

Now you have to attach staps to the person, but its an interesting build using an arduino to tell when someon is not telling the truth.

Interesting farm platform (acorn)

The author is pretty colorful. Its using an ardiuno/RPi combo for controlling it, right now its just the platform and its goal is to automate farming. I think this looks interesting, but has a ways to go.

Another nice CNC foam cutter

This one seems to let you “expand” the width of the table for the cutter. https://www.hackster.io/news/make-your-own-four-axis-cnc-foam-cutter-on-the-cheap-9b421e8269e5
