Letter to morse code converter

Posted on January 4, 2022 by robertwilkie

Using a Micro:bit, the author basically has a lookup table on it to convert a character (select thru the buttons) to its morris code value.

Interesting adds for a workshop

Posted on January 3, 2022 by robertwilkie

First jig is to hold material down on a drillpress. Not so sure I would do this one. Second jig is an interesting feather board build with PVC pipe for the “feather”. I do like this build, but I think I would make it so you can replace the pipe parts every so often as needed. Third jig is for a trim router, basically giving it expandability options (handles, endstops, etc). Fourthis a contour duplicator…I think I would just buy a cheap one myself. Fifth one is a circle making jig to draw circles with, and then round over on a router table. my 2 cents, I would just make a router based jig.

Nice build for a small portable sanding station

Posted on December 31, 2021 by robertwilkie

The author put alot of work and thought into this one. Not so sure I would do this build as it involves alot of expensive to buy parts vs parts I just have on hand.

Making a Dowel Making Jig

Posted on December 29, 2021 by robertwilkie

Me…I’ll just buy the dowel. But still if I needed to make a custom size, this could be a handy build.

Converting old hoverboards

Posted on December 25, 2021 by robertwilkie

So I came across some old hoverboards that where tossed out, most likely to the batteries not holding charge anymore. I got to thinking of projects for these and found out that one, there is opensource firmware for some of these systems, and two, there is alot of other folks ahead of me on this (links below):

Another nice CDROM to CNC build

Posted on December 24, 2021 by robertwilkie

What I like about this build is the only bits you use from the CDROM is the rails and motors, the rest is 3D printed parts. My 2 cents, I would use the motor and slide 3D printed parts, but use wood for the frame itself.
