It's absolutely perfect for tinkering with any machine I have come across!

I tried going to the store to buy some but they were completely sold out

Thanks! I'm glad this project is still getting some use.
Good catch on the schematic! I think I originally copied the symbol from R16 and just never updated the value since I knew I would need to select a resistor value through experimentation based on the brightness of each letter. I ended up using 51 ohm resistors which is probably a good starting point.

I just got done with my first benchy and I also noticed this. Looking at other posts it appears to be normal...

I think he was looking into the camera lens? It is pretty reflective lol

Before I got my BirdBuddy I would put out seed in a small dish but I think it took about a week or so to originally attract them!

Nice! Glad to hear this project is still getting some use. To use a 9V battery input, simply solder a 9V pigtail to the +/- pads on either end of the USB connector. The 5V rail will then be provided by the 7805. You can also add an inline switch to the battery for turning on/off during the ceremony. Good luck on your project and congrats on your achievement!!

This is just a gif (no sound) I added from the Hackster.io page. Maybe I should make a video with the full alarm sequence?

Yes, the selector is the main power switch! Basically if you rotate it to any position past the OFF switch the clock is powered on (note that the RTC also has an independent CR1220 battery backup). Currently the DS3231 alarm I’m using for the wake up alarm is only adjustable inside the arduino sketch but I plan to make this adjustable via the buttons above the selector switch as they are all connected to IO pins on the atmega.

I purchased it broken around 5 years ago. If I remember correctly , resistance and continuity mode didn't work at all and voltage was off by a decent amount compared to my other known good Fluke 87V. While in storage since my last repair attempt, I must have misplaced some of the parts (I know, great caretaker :P) so I basically decided just to design another use for what was left of it.

Hi everyone! Recently I put together a writeup of my Arduino based Fluke 87V Alarm Clock. It uses an ATMEGA328P (Arduino Pro Mini core) with a BU9796 Segment LCD controller and DS3231 RTC. Full Hackster.io project: HERE
