[Theme] Your DIY projects

[Zang]

Thank you guys for kind words for my humble work and thanks all for sharing your incredible projects. I am so happy I found this gold mine The below was just a very simple project from today

[Nasos Kosmas]

I forgot to mention Zangs project: pyrography it’s very nice, unice  and related to guitar as I see
I know Kay from a very old spring reverb unit I sow once, rare, the guitar is very old but still in a very playable condition
Thank you for your kind words

Thanks Nasos! Mine was quite simple. The hardest part was to sand the original finishing off

My latest Arduino project, an electronic version of the Magic 8 Ball. Ask a yes/no question, press the button and one of the original 8 ball answers will pop up on the display in random order. There are 20 answers, 10 are positive, 5 negative and 5 ambiguous. I may take it from the breadboard to a finished project and make a few as gifts if I can get my motivation level up a bit. It’s the end of the year, I worked hard this year and I’m not feeling too ambitious at present. Next year I may not have to work as hard, the 8 ball tells me I’m going to win the lotto.

It's been almost three years since my first negative copier 

This is my latest one made last week.

With your setup, you have a ring light pointing away from the camera, but the white reflector sends light back to the slide/negative thereby illuminating it.  If I am correct so far, how uniform is the illumination when it reaches the slide/negative?

One advantage of your setup is that it is more operator friendly than having the light pointing at the camera with attendant light spill into the photographers face & eyes.

Hi Hugh,

The main purpose of the setup is to get decently even lighting. I tested many setups and only this one gives me near perfect even lighting for relatively cheap.

Thanks,

Another wood burning project.

I was listening to Bartok’s piano concertos while wiring this DIY loop switcher.  Then I noticed that tha cables had been shaped like Fibonacci series spirals!

Very much so.  Bela helped me to do the finishing touch!

Another recent project.  This is a specialized LED array to investigate the internal bracing of acoustic guitars.  The original array consisted of three pairs of white LEDs driven by a single 9V box-type alkaline battery.

Now I decided to power it up and added two more pairs.  In order to provide the necessary current for the total of five pairs of LED array, I employed a DC-DC boot-up converter available cheaply on Amazon and two AA NiMH batteries.

The conversion was successful.  The last image shows how this tool is used: the bracing of this replica of a Rene Lacôte guitar from 19c appears as two dark lines oblique to each other on both sides of the bridge.
