Finished a woodworking project today

This long term project has taken several months but I finally finished it today.  It's a hairdryer and curling iron rack for my wife.  I made it from a piece of reclaimed maple butcher block table top.  The glue had failed on the top and left me with a bunch of 2x2 maple blanks.  I processed them and glued them up into wider stock for the rack.  The joints are simple glued up grooves with no mechanical fasteners.  It's held to the wall with toggle bolts in the drywall.

Yesterday's build - a world apart from robots

I actually started this build months ago when I did the coptic stitching on all the pages for my new journal.  Yesterday I finished it with my first attempt at binding the pages into a cover.  I also cut the linocut for the cover yesterday.  For a first attempt I'm pretty happy.

One day robot

In all my time building robots I've never built a line follower and thought it was about time. I figured the electronics from a Snappy type robot would work as a line follower, so I decided to give it a try.  I built up another board, re-configuring the light sensors to look at the floor this time.  Then I designed and printed a new chassis.  This is the result...

The software turned out to be incredibly simple, I just added about eight lines of code to the light seeking code running Snappy, and abracadabra the robot follows lines...

Snappy got his name from one of the Smurfs - I'll have to go through the list again and find another one for this guy.

Another Robot is Born Today

I posted stills of this little guy a while back when I finished the 3D printing and assembly but couldn't put up any video because I still had some soldering to do.  Well I got that done this evening, and he's up and running now.

His name is Snappy (one of the Smurfs) and he's a real simple ATTINY45 based light seeking robot.  I've got parts to build 7 or 8 more of these, so you may see some other variations in the future, but as is I'm pretty happy with him.

Sunday's build

Today I scratch built a FliteTest Mini Scout while watching the NFL playoffs.  It's small enough that I can fly it in the neighborhood park that's within walking distance of my house.  The build was pretty straight forward and went without a hitch.  I can't wait for the weather to cooperate so I can maiden it.

Introducing Pablo

Well, I'm calling my build of a BoB complete (for now), and I've named him Pablo.  I have another robot named Stella - after the character in the Streetcar Named Desire.  I also happen to have named my CNC machine Stanlee - after the famous Stan Lee of Marvel Comics.  I didn't know it at the time, but in the play Streetcar, Stella's husband is Stanley - So I thought it might be cool to stick with the Streetcar theme and name this little guy Pablo - after one of Stanley's poker buddies.

I had originally thought I would put leds in his eyes, but decided that would be too much and instead printed his eyes and pupils and just glued them on.  I installed his on/off switch in his backside, and I'm calling him done.  All he does right now is walk and I've got ideas for other behaviors, so I'll probably pick him up again some day for further work, but for now he is what he is.

One day build

Yesterday I not only got BoB's mouth working, I designed, printed, and assembled this.  It's an RC pan mount for my Mobius camera.  It's designed to be temporarily mounted to RC vehicles for onboard footage, and is inspired by Andrew Newton's video.  I won't go so far as to say everything on the design turned out as intended, and I will probably tweak some things and reprint it, but all in all I'd call it a successful one day build.
