Wobots, we all loves wobots don't we?

After the hand held gps speedo I decided to hack a toy robot I had on the shelf
with a small PIR sensor and an mp3 player board
Heres the basic core of it on a small breadboard powered by USB

Heres the robot:

I already had an Arduino 'friendly' sound board but it was too fussy about file types,format, encoding, TF card size and such
but the DFrobotplayermini is cheap (£3.50 ish )and very forgiving about what you want it to play
and will take TF cards up to 32GB.
I'm just using a tiny fraction of a 500mB one I had knocking about atm.
The robot head had a momentary button underneath which turned on a small bulb in the body
I removed all that and fitted a latching on/off switch under thead and fitted the PIR sensor
in the body.
Stripped it down, sprayed it satin black cos tactical/spec ops 'n all that bollox and fit a 50mm speaker and 2 led eyes
in the head.
gutted a cheapo phone power pack for 5V psu and charging cos its cheaper and easier than buying the pcbs alone
and fitted that

Had to Dremel out the clear plastic window on the front because I found it was buggering up the sensor
(Took me a wee while to realise that, I thought I'd broken it.)
Soldered the Nano and mp3 board down on some Veroboard, mounted that to the back door
and got the basic 'detector senses and turns on the leds' part working

Assembled and charge port on right hand side of body

LEDS come on when movement detected

Short test run with sound, movement triggers a sound file
(SFW version btw all sweary stuff avoided)
Not sure if I can embed this file so here is the link
