Sum for 1 device:                    approx 18.67 (excl shipping)
Sum for 1 device, building 10:       approx 15.19 (-1.02Euro 100% PCB overproduction for 0.1Euro/cm^2 assumed, -0.189Euro resistor savings, -0.24 fuse savings, -1.98Euro solarcell savings, -0.05 battery savings)

============== Alternate version with 3x white + 1x red LED ====================
The step-up voltage will be 3.49V instead of 4V, making the pocket light more efficient
As above, but change
R1:       68Ohm           SMD-0805 68,0
R2,R3,R4: 18Ohm           RND 0805 1 18
R6:       620kOhm 1%      SPR-0805 620K
LED1:     red             LED 5-10500 RT
LED2,LED3,LED4: white     LED 5-23000 WW

============= For the aluminium case ==========================================
Replace
U$3 by TASTER 1082.5, it has a lower height (and is green).
EN AW-7075 plate with 10mm thickness
EN AW-7075 plate with 8mm thickness
Plexiglass plate with 2mm thickness
Use ENELOOP AAA 1Z
