Weekly Project: Go Green GBA--A Solar-Powered Game Boy Advance

Step 2 Open Sesame--Maybe

Your most difficult challenge won't be locating a trio of suitable batteries, rather it will be getting inside the Solar PAK. There are four Triwing "tamperproof" screws fastening the battery compartment together. Don't be fooled into thinking that you can simply push a straight-blade screwdriver into these screws and force 'em out. Instead purchase a Triwing screwdriver. Sears, Roebuck and Co. sells the Craftsman 32 pc. Security Screwdriver and Bit Set (Sears item #00947486000 Mfr. model #47486) for less than $25 which features four Triwing bits.
