Arduino Enclosure Modding

Before:

Notice how the surface isn’t smooth with the plates in.

After:


How did I do that?
First I used a layer of plastic model glue to secure the panels in place. Once the glue had dried I sanded as much as i could to make the panels flat with the case surface. first with course sand paper 40 grit then move my way up slowly to 250 grit.
Next I applied a layer of primer paint. let it dry then sanded it down with 250 again.I then applied some epoxy to the cracks with a razor blade to make sure that the surface was as smooth as possible. sanded smooth then applied another layer of primer. once the primer was dried for a day i took some very fine wet sand paper and wet sanded the case till it was super smooth.
now it looks like there were never panels to begin with :)

Speech Synth Reverse Engineered

After a ton of probing and trace fallowing I have come up with this schematic :)
M14 is the piggy backed roms only one side of the pins of the chip are used
IC2 is the TM5200

Table of WTF magic

now for power im using this circuit

work fine with my arduino, now to get to coding and building an small amp for the sound out

Adafruit’s Arduino Enclosure – 1.0 : A review

No Moogle is not selling out and getting sponsorship from Adafruit :-D I just really like this product
Arduino Enclosure – 1.0
I received my enclosure today and was reminded of my past plastic model building as a child from the smell of the case :)

This case is very well designed and should be very easy to paint and customize. It looks like a lot of thought went into the design of the lcd mount with extra space to add your own clear plastic panel to protect the lcd.
There is tons of room inside the case for any lipo battery system you could possibly want.

But there is a lack of mounting posts for an arduino pro :( just a little too short.

slight problem I found with the case is it has a weak spot when force is applied in these directions.

This should be a easy fix for the next revision of the case, just swap the flange around.
Over all though I say this case is definitely worth the $ if you are looking for a case for your arduino
