Build your own metal detector

Posted on September 14, 2022 by robertwilkie

https://hackaday.com/wp-content/uploads/2022/04/metal-detector-main.png?w=800 Nice build. It seems to work pretty good to. My 2 cents…I think I would just buy a used one myself. https://hackaday.com/2022/05/02/diy-metal-detector-gives-you-the-mettle-to-find-some-medals/

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/

Neat build to generate electricity

Could be a nice school poject. https://www.instructables.com/INSERT-NAME/

A python compiler

Posted on August 30, 2022 by robertwilkie

This looks interesting, it’s a native compiler for python. I do like writing code in python, but its slow to run compared to C/C++. Not sure how good this is yet thought. https://github.com/Omyyyy/pycom

Add a kill count to a flyswatter

Posted on August 25, 2022 by robertwilkie

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

Logic analyzer for RPi

Posted on August 24, 2022 by robertwilkie

Nice project to convert a Raspberry Pi into a Logic Analyzer, looks like it still has a ways to go, but its a nice start. https://github.com/gusmanb/logicanalyzer

Cool 3 color CNC wall plotter

Posted on April 14, 2022 by robertwilkie

Reminds me of the Maslow CNC in its build. Most of the parts are 3D printed and it has an internal gear to switch markers. I like how the author uses vasoline for “grease”. Parts here https://www.thingiverse.com/thing:4192091

Making your own lie detector

Posted on April 6, 2022 by robertwilkie

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.
