Copper pipe guitar wall hanger

I’ve finally made a wall hanger for my telecaster.  Everything was scrap from other projects.  The wood came from the underside of a dresser that got taken apart, the copper is from old baseboard, the wooden “plugs” in the copper are from something years ago (honestly, I forgot I even had this in the basement).  The “feet” on the lower pieces were from an old parts CB radio I took apart years ago.

The hanger itself consists of a board with two pieces of 3/4″ copper held in place by 3/4″ dowel whittled down to fit tightly in the pipe.  These pieces of dowel then got cut at roughly a 15 degree angle and screwed to the board.  This makes the copper pipe mounts slope upward, holding the guitar securely.  The copper pipes slip over these and then I put two similar pieces of dowel (cut straight this time) in the top of the pipes to make caps.  These caps protect my guitar from nicks and scratches while loading it into the hanger.

The two lower legs are to keep the guitar from trying to rotate while hung on the wall.  The guitar just barely touches them when it is in the hanger.  These pieces are 1/2″ copper pipe and have plastic “feet” sitting on top with long screws going through them that mount them to the wall.

It works great and I love the look.

True bypass with DPDT and LED indicator

Typically to get true bypass with an indicator LED, you need a 3PDT.  Sometimes these are hard to source, and even when found, quality can be less than perfect.  To get around this you can use relays to control switching of your circuit, or you can use Joe Davidson’s LED trick.  I’ve used this successfully and really love the simplicity and the fact that I can use parts I typically have on hand already as well.

Joe Davidson’s LED trick allows for using a SPDT switch, LED indicator, and still maintaining true bypass.

Simple guitar cable tester

With social distancing being the current norm, I’m working primarily from home right now.  As such, I found I needed to clean my work area.  Doing this, I also found I had a lot of random bits around and decided to make something of them.  Here is a simple cable tester I’ve made based on ideas found at diystompboxes.com.  I shared the idea and more photos on SSGuitar.com, but here is the short version:

Note: I chose to omit the speaker and subbed R1 with a 1k to reduce brightness.

 

Good cable!

No lights on means the cable is electrically open.  Just the red LED on means there is a short.  Both lights means you are in business!

Raspberry Pi Digital Signage

There have been many different attempts at inexpensive digital signage over the years.  My favorite, one that I use regularly where I work, is Raspberry Pi for digital signage.  Put simply, I set up a Raspberry Pi to load a continuous loop of a Google Slideshow.  This refreshes once every 15 minutes to load new content.

Here’s how we do it.

First, run all updates on your new Pi. (sudo apt-get update, sudo apt-get upgrade).  I like to also run sudo apt-get dist-upgrade and sudo autoremove to fully upgrade plus clean things up.

Next, install clutter and automation (sudo apt-get install clutter and sudo apt-get install automation).

Set your auto config to keep the Pi from going to screensaver as well as load the slideshow automatically on boot.  The file you need to edit is /etc/xdg/lxsession/LXDE-pi/autostart.  You’ll want it to look like this:

@lxpanel –profile LXDE-pi
@pcmanfm –desktop –profile LXDE-pi
point-rpi
@xset s off
@xset -dpms
@xset s noblank
chromium-browser –noerrdialogs –disable-infobars –incognito –kiosk http://web.address.com

Now edit crontab to refresh every 15 minutes (crontab -e):

#Refresh every 15 minutes
*/15 * * * * xte “key F5” -x:0

That’s it!  Enjoy your new digital signage!
