Simple automatic soap dispenser

Posted on July 2, 2020 by robertwilkie

Using an arduino, IR sensor, and a servo, the author built a pretty simple conversion for a pump action soap dispenser. Could be a simple project to do with kids. https://www.instructables.com/id/Automatic-Soap-Dispenser-Using-Arduino/

Nice 3D printed stand for an electronic mircoscope

Posted on June 29, 2020 by robertwilkie

The author made this build for a scope based webcam that he could hold a circuit board down on and solder components too. Me…yeah I don’t go that small in boards (and usually use thru hole). But I could see … Continue reading →

nice multi angle table saw jig

Posted on June 26, 2020 by robertwilkie

This can be used not just for angled cuts, but to “straighten” out boards that have a curve to them. Relatively simple build too. https://www.homemadetools.net/forum/4-1-multi-adjustable-table-saw-jig-78635?homelistings#post155545

Using a conrete paver and foam for a stand for your 3D printer

Posted on June 19, 2020 by robertwilkie

Interesting build, the paver gives some stability, and the foam helps dampen the vibrations. https://blog.adafruit.com/2020/05/19/the-best-2-upgrade-for-your-3d-printer-3dprinting/

Cool CNC scroll saw

Posted on June 11, 2020 by robertwilkie

Pretty complex build, the author 3D printed the bits he needed to make a CNC with a scroll saw. Me….not entirely sure the benefit of this over a regular CNC, but its a nice build. https://hackaday.com/2020/06/04/cnc-scroll-saw-makes-promising-first-cuts/

Another simple ventilator build

Posted on June 10, 2020 by robertwilkie

Clever build. I don’t see these builds ever making it to US due to regulations, and fear of lawsuits. But maybe other countries can use these ideas. https://www.instructables.com/id/Intro-RespiArt-a-Simply-Ventilator/

Nice 3D printed face mask

Posted on June 6, 2020 by robertwilkie

You use this with some transparency sheets (old school sheets where you printed out your “slides” for displaying on large screens). https://www.instructables.com/id/Caretas-Impresas-En-3D/

Another nice shield build

Posted on June 4, 2020 by robertwilkie

This one I could do. I have to say I was impressed with the build (the author “bends” the plywood to a curve). One thing the author could have done a little differently is to put grooves into the back … Continue reading →

Another version of the 3D printed face shield

Posted on June 3, 2020 by robertwilkie

Since I am a glasses wearer, I am interested in these sort of protection systems over straight masks. Downside is you need a good size table to print it out.https://www.instructables.com/id/Face-Shield-Visor-for-COVID-19-Frontline-Workers/
