Nice CNC build

Posted on December 26, 2019 by robertwilkie

This is the author’s second version. The frame is 3D printed out and the build can do plotter, drill, and laser based work. Looks sharp too. https://www.instructables.com/id/TRIPLE-CNC-MACHINE-UPGRADE/

Make a snowglobe, with LEDs

Posted on December 25, 2019 by robertwilkie

OK the authors take a different approach to the mason jar snow globe by adding in LED and a 3D printed base to the mix. Looks pretty nice. https://www.instructables.com/id/LED-Mason-Jar-Snow-Globe/

Interesting jig for table legs on a tablesaw

Posted on December 24, 2019 by robertwilkie

The build allows for the leg to be tapered, and then spun to round it out. Interesting take if you do not have a lathe. I can see making a baseball bat this way too.

Interesting dust collector build, good for mini CNC’s

Posted on December 23, 2019 by robertwilkie

Nice build, the author 3D printed as simple dust cyclone for a mini CNC. This could be built up more by adding a bigger waste container. I like the use of PC fan too (quieter than most vaccums). https://www.thingiverse.com/thing:3961313

Nice add to christmas lights

Posted on December 20, 2019 by robertwilkie

The author basically uses a CNC cutter to cut out “wings” to add to the lights. Nice build overall. https://www.instructables.com/id/Navi-Christmas-Tree-Lights/

Cool infinity mirror

Posted on December 18, 2019 by robertwilkie

Also doubles as a clock. This was alot of work for the author, I wonder if he could have simplified a few steps. https://www.instructables.com/id/Make-an-Infinity-Mirror-Clock/

Cool servo tester

Posted on December 18, 2019 by robertwilkie

It provides the angle of rotation while you use a pot to change it. Nice build overall. The color display is also pretty cheap now these days ($3). Something I may need to keep in mind for the future. https://www.instructables.com/id/Servo-Tester-2/

Combine vinegar, steel wool, and coffee grinds to make wood stain

Posted on December 17, 2019 by robertwilkie

I got a kick on this one. Pretty cheap solution to make a simple woodstain to use. Me…I just get a $5 can myself…all pre-mixed and ready to go. https://www.familyhandyman.com/woodworking/staining-wood/how-to-stain-unfinished-wood-with-used-coffee-grounds/

Nice write up on using L298 with Arduino

Posted on December 16, 2019 by robertwilkie

L298’s are good motor controller (relay) chips. The author found there are not alot of good write-ups on the combining the two. Of course there are many write-ups on using shields that have this chip built in… https://www.instructables.com/id/Connect-L298N-IC-to-Arduino/
