My grandma has a weak grip, because she had polio when she was little.
But she likes playing Braintraining on the DS.
This is what I've done to make it easier for her to play the game. I'm going to take it up to her at Christmas.
(My dad took the photos, because he didn't want sugru fingerprints all over his camera.)
Step 1: Materials
Sugru (my dad has loads, and he let me have some).
A plastic milk bottle.
Sharp knife (I borrowed by dad's little Leatherman.)
Rotary tool with a grinding thing on the end - I used my dad's cheap cordless one.
Things to poke into small gaps and press Sugru into place - I used scredrivers and an old pen.
Step 2: Using the Sugru
This is from the Sugru website.
For best results, we suggest washing and drying your hands before use.
How to get the most from your sugru:
• Ensure surfaces are clean, dry and free of dust and grease
• After use, wash hands thoroughly with warm soapy water and a rag.
• sugru may leave a mark on surfaces or stain fabrics.
• If necessary, sugru can be removed by cutting off when cured.
• Store in a cool dry place below 21C.
• Don’t use sugru to stick up heavy objects.
• sugru isn’t suitable for use on some plastics.
• sugru will not stick to every kind of material - if you’re unsure, it’s best to do a small test first.
• sugru isn’t suitable for use in direct or prolonged contact with food.
• Keep out of reach of children. (Shhh! Don't tell them I'm using it...)
Step 3: The handle
This is the most important bit for my Grandma. She doesn't have very much strength in her grip.
I used the handle of the milk bottle to make a sort of hook.
I folded one end of the handle in on itself to hide sharp edges and hold up Sugru.
Sugru doesn't stick to some kinds of plastic, so I made sure it would stick to the DS by roughing up the surface with the rotary tool.
(I had to do it twice, because I roughed up the wrong bit first, but my brother spotted the mistake before it was too late!)
A sausage of sugru around inside of the handle, and a sausage around outside the handle held it in place. I used the pokey things to reach inside the handle and press the sugru down.
MAKE SURE YOU DON'T COVER UP ANY HOLES OR BUTTONS WITH YOUR HANDLE!!
Step 4: The Buttons.
I scuffed up the surface of the buttons with the grinder thing, and added little blobs of sugru to the direction buttons, to stop my grandma's thumb sliding off. I used the edge of a flat screwdriver to make slots in them.
I put little blobs on the XYAB buttons as well, and made a little dip in the middle of the blobs.
The slots and dimples mean my grandma can hit the buttons with the stylus, so she doesn't have to fumble about putting the stylus down and picking it up again.
MAKE SURE THE BLOBS ARE NOT TOO TALL, OR THE DS WON'T SHUT!
Step 5: The Stylus
Styli* are really skinny, and my grandma has trouble picking them up and holding them tight enough to use.
I added a fat blob of sugru to make it easier to hold, and made the blob roughly triangular, which helps stop it rolling away as well.
The fat stylus won't fit in the special hole, so I trimmed a bit off the already-open edge of the handle, and now the stylus drops in there (that was my brother's idea as well).
*Oh, look, Latin!
Step 6: What Grandmother?
Clever readers will have spotted that my grandma isn't in the photos.
First, she doesn't like having her picture taken.
Second, she doesn't know about this yet - I'm going to take it up for her at Christmas.
