Step 3: Safety alert ...
NOTE- adults should take these spikes away from kids (OR AT LEAST SMOOTH OVER THE SHARP END) as boys especially will promptly play "warriors" with them & eye damage could arise. The hollow tubes tempt as "pea shooters" as well ...
A more peaceful "waste not want not" could involve blocking the drainholes with hot melt glue -
Step 4: Rain gauge !
- and there's an instant RAIN GAUGE ! Of course it should be higher off the ground to prevent splashes- maybe use 2 tubes to make a taller one?
Step 5: Linked tubes?
The lamp support tubes in fact will link together quite well, perhaps to suit structural "extension" challenges. Here some Kiwi 8-10yo. scouts try to touch the ceiling with about 20 of them!
The lamp module features an energy efficient white LED (Light Emitting Diode), a sturdy switch, internal rechargeable AAA battery and small ( ~2V at 30mA) solar PV ( Photo Voltaic) cell. These nifty parts tempt for enhancement !
BEFORE tackling the more ambitious lamp conversion however, consider simple LED "cover" fun! .All sorts of everyday items light up a real treat when illuminated from within- wine gum sweets have been found especially suitable - see comments at end).
Perhaps the most rugged translucent covers are table tennis/ping pong balls- simply piece a hole in their bottom & place over the LED. Simple designs & messages can be further written on the ball surface to suit. Note: Try to avoid using orange table tennis balls as their colour looks rather too "flame" like & at night it may be confused with a real fire...
Younger kids predictably love them at bedtime, & the LED light is perfectly safe if (& WHEN !) they fall asleep. The setup will of course later need daylight recharging. Just tipping the lamp over (so the PV "sees the sun") may do, but a small hole drilled in the side allows threading a cord to suit hanging at a sunny window etc.
NOTE: Although it suits convenient night time on/off action, THE LAMP SWITCH MUST BE ON FOR DAYTIME CHARGING TO OCCUR !
Step 8: LED lamp module enhancement
But the lamp module further tempts for enhancement by LED repositioning - follow the next few steps for insights. You'll need just a small Philips head screwdriver & simple tools, but things are a tad fiddly & adult help will be almost certainly needed.
NOTE: Lamp variations have emerged, and the model shown here is a 2011 era. By 2014 the lamp had simplified with fewer screws and a smaller switch - best to check details of exactly what's on offer before rushing in,especially for a group project!
Step 9: Pre opening parts alignment alert !
Before removing and modifying the module it's suggested that small felt tip pen alignment marks are made to ensure correct reassembly. Excessive twisting around of the top & base may otherwise occur,leading to broken wires... When it's revealed (after case opening) perhaps also add similar ID marks ( +/-) for the battery. This ensures CORRECT polarity replacement if it's removed.
Step 10: Open sesame !
The lamp module easily opens with a small Phillips head screwdriver - the outer case on this lamp has 3 (black) with the small circuit board inside another 2 (silver). Some lamps however have fewer. Don't misplace the screws- perhaps put them in a small dish!
NOTE: Although it allows convenient night time on/off action, THE SWITCH MUST BE ON FOR DAYTIME CHARGING TO OCCUR !
Step 17: Descriptive label etc.
Step 20: Finished item
Step 22: Bedside etc
Of course the pendant style also allows hanging on a sunny hook etc for an "auto on" bedside lamp. The vertical PV particularly suits solar pickup of the otherwise fleeting low angle winter sunshine. Ensure the PV faces into the sunbeams of course !
