Check out the creation
Chip (angler fish)
About 0.5 meters long
Weight about 4kg
2W power
So fell into the hands of the remains of the mafona (part with the grille from the speaker).
Successfully folded them like this - it turns out the head.
I think it is necessary to collect it somehow will Chip.
In her eyes it is clear that this is the creation of Audio Chip
For almost a year, he thought about how to stuff this creation, what to use
And how to fasten all this and what the torso wanted to do.
Such devices were available.
PDA Ipak2190,
yusb charger (homemade assembly of 4 AA batteries 2500 mAh),
bluetooth zip,
mp3 player
All this periodically required charging the most important thing somewhere all the time was gone ...
On ipak, the speaker is also rather weak.
I decided that it should be combined in one case.
So there will be an amp for the pda and charging.
As a result, in her wort, it contains:
LED backlight
chinese power supply
ULF stereo block (amp from the Chinese mafona-assembled from what came across),
3 speakers (two speakers-eyes, the third inside the head-on the bass),
put the switch to the choice of sound from the PDA / mp3 player,
charger for PDA (5V stabilizer block),
charger for bluetooth ZhiPiS (5V stabilizer block),
Accumulators from the radio 12v [for autonomous operation of the amp] (which the half-dead found them nezhalko)
charger for usb charger [for autonomous operation of a PDA]
Instead of a current-limiting resistor yusb of a charger, I had to put a light bulb in my mouth (now a weak light is out of my mouth)
There were already LEDs in the eye rings (so the eyes are red)
I needed to search for the light - it means there will be a fish-angler (deep-water predator)
The belly, part of the fins and tail had to be made from papier-mГўchГ© (newspaper + PVA glue)
Head made of plastic, cold welding and car putty.
tightness of the design is not provided
Because its weight is about 4 kg, it will not swim 100 pudof.
Within six months, a lot of design flaws were also found.
- bad cooling (Chinese transformer),
- fragility (it is impossible to drop, it is not metalic),
-plugs / fragile pda connectors (it would be much easier with miniUSB)
-small (toggle switch nowhere else to put),
Illumination is too small
-the capacity of the batteries is not enough (per amp),
-and lithium batteries do not like to sit long on the charge,
- heavy
Who can collect something without the listed lacks?
