Bierley ColorMouse and MonoMouse are great little devices very easy to use for visualy impaired person. Versions I'm aware of have only to buttons: on/off and vision mode button which digitally enhances contrast.
Unfortunately they lack one major feature: magnification level adjustment. They have fixed magnification level (there may be two versions with different magnification as far as I remember), which can be annoying. You cannot even read a newspaper without constantly swiping the device from left to right. Because of that, I've made a simple stand, that rises Color/MonoMouse so the magnified image contains the whole newspaper column.
Model consists of two feet, body, cable strap and reflector. To assemble it you'll need 6 small screws (3x12mm should be enough).
You can achieve different magnification level if you want, by adjusting feet height before printing.
I've develop this stand for SCART version but USB version appears to look the same, so it I think it should fit just fine.
- To achieve smooth movement sand the feet. I used sand paper up to 2000 and feet came out really smooth. There is very little difference in friction between standard Color/MonoMouse (which has teflon sliders) and same device with stand.
- Screw all parts together (wire strap after mouse beeing placed on the stand).
- Stand should fit tightly into the mouse, but if you want, you can use a rubberband or a piece of string to strap it to the defice using a hook I've incorporated.
- Also remember to adjust focus by twisting the lens.
Be warned: engineers from Bierley made a lot of effort to make your text highlighted with exact amount of light needed. When Color/MonoMouse is rised, this amount of light changes (generally decreases) and automatic contrast enhancement can become harder to use. To overcome this problem you can:
- print the whole thign with white or transparent plastic
- use the device in well illuminated space
- use the reflector model I've provided. Since the internal part of Color/MonoMouse is black you can achieve slight improvement by printing the reflector and sliding it into the mouse. Just remember to print it in the vase mode, without bottom layer with white plastic.
- cover the reflector with aluminium tape or mirror wallpaper to increase the amount of reflected light.
I've been thinking about incorporating one additional led into the stand, but since I now have a very little user feedback, I decided to wait and see if it is really necessary.
