Retro MP3 Player: The NASA Pod

Picture of Retro MP3 Player: The NASA Pod
Steam punk is played out, this is straight up NASA punk. Or at least I imagine if it were the 1960s space race and NASA was commissioned to make an MP3 player, this is what it would look like.

This project uses the Daisy Mp3 Player kit from MAKEzine, a VU meter from this instructable , and a case from Curious Inventor.

Step 2: MP3 Kit

Build the mp3 player kit following the instructions that come with the kit. They are very good and I can't better it here...

Step 3: VU Meter

I built the VU Meter from my VU meterinstructable here, EXCEPT I didn't go with the LED bar graph. I used a RadioShack 0-15v panel meter.

Since we send all the power to the meter, I tied all of the negatives from the LM3915s together and then to the meter.

Step 4: VU Meter positive

You'll need to use a resistor or two to limit the + voltage going to the meter. I used a 1k2 and a 4.7k resistor soldered together to get the right voltage for the meter to read accurately.

Step 5: Solder your switches together.

Solder your switches together, I used crimp pins and connectors to connect the switches to the MP3 player kit.

I used a handy little tool from www.CuriousInventor.com, a crimper for this small connector. You don't need this, you could solder or use pliers, but it is so much easier to use.

Step 6: Box

Time to drill the main hole in the box for your panel mount gauge.

The meter from RadioShack meter included a template to use for drilling the hole. I used a drill press and a bimetal hole saw.

what is the name of your power supply ? how much it cost ?
LAB PSU 0-15V3A - PS1503SB

havanacus raises a good point about knowing which switch does what. NASA would surely label them. This page: http://history.nasa.gov/diagrams/apollo.html has some good examples.

He he, definitely need 'Main Bus A' and 'Main Bus B'

I'd love to see a nixie tube track-counter or something like that. :)
oh.. Nasa has some lights and stuff on most of their stuff, maybe you could use some LEDs and get some big cover lenses so they look like incandescents.. but don't draw too much power.. What do ya think?
I love this.. I usually try and incorporate some humour with my Projects, Retro is hilarious though.. Great work and great sense of humor.. I love it. I want one, maybe you could sell them, you never know.. Lolz Thanx.

All that's missing is some retro corporate logo on the front!
Neat! Great use of existing instructables to create a masterpiece of your own. Although, it may be more convenient for the reader if you used little snippets from those instructables to explain either the theory or reason behind that step. Great Job!

I love switches!... Which one controls power?... It should be big and red if you ask me... I'm partial to this style...

That switch rocks! I need to change it out. The power switch is the one on the bottom right. -Joe
That is a sweet toggle switch. Thanks for the link.
