World's most overkill flashlight.

It's the world's most overkill flashlight! (In progress.)
Parts purchase in 3 weeks, then it's soldering + cutting + destroying + gluing + fun :yayds:

Features:
-Altoids tin
-Arduino Duemilanove
-10000mcd RGB LEDs (make any color) + green charging LED
-Rechargeable 2000mAh 3.7V Lithium Polymer battery
-MAX8903A-based 2A LiPo charger (USB/wall wart)
-Color LCD screen
-4 button input
-USB OTG microAB port (3in1 functionality: MintyBoost to charge other devices, charge flashlight, reprogram flashlight)
-Real time clock with loud alarm buzzer
-Light/temperature/vibration sensors
-Expandable! (445000mcd RGB LED blaster controlled by WMOF, or how about a wirelessly controlled LED lantern?)
-Dynamo/solar panel compatible

Okay, rant over. I'll post up some pics later. I almost have a CAD model done.
(Total cost of all parts above: $200+!! I accept donations! :D)

wchill before I even think of donating to you can you shine it in your eyes for a good 20 seconds 1 minute to test its overkillness. Then tell me how your eyes feel. :lol:

Everything I'll be using will be as space-efficient as possible.
The screen will be mounted on the top of the lid with standoffs, giving me a bit of wiring room underneath the screen's board.
On the other side of the lid, I'm going to attach a protoboard so that I can fit my own custom circuits easily.

BoxShot: Sure, I'll do that... at minimum brightness hehe :D :D :D

mercluke: The Arduino is driving the screen and LEDs, plus any extra stuff I add on. Like the 445000mcd RGB LED blaster addon.

I'm sorry, but I'm not much of a hardware guy, just interested in the project.

But, what does and Arduino do?
 
wchill
Arduino = 8-bit (heh) microcontroller used in tons of DIY electronics projects, providing general I/O, serial, hardware PWM, analog inputs, etc.

Nah, I have a broken MintyBoost lying around that I can fix in about 5 minutes, plus all my flashlights are broken.
Plus, no one has a flashlight like mine :D

Okay, sure :D
The only real challenges here are fitting everything inside (possible), some small-as-fuck SMD soldering and devising a space-efficient LiPo charging circuit. Maxim-IC's evalulation kit for the MAX8903A is $60 + shipping... too much ehhh...

Oh, I thought you were going for some custom "tube" design :)

I think the question we all want to ask is, "Does it have bluetooth?" If not, it does not fit the definition of "overkill."

This better be overkill enough to cut a person's hand and be coveted by an evil emperor from space!
 
wchill
I was going to make it a touchscreen, but decided not to due to it adding an extra $100 to the project cost. Maybe in a future upgrade.

What would I do with Bluetooth? I don't have space for a module in the design either.

I have to ask why the lights are rated in milli candelas when they are in the 10^0 range but oh well.

Same problem with the "Rechargeable 2000mAh 3.7V Lithium Polymer battery" but aside from that I got (an admittedly NiCd) battery at 3.6V and 4Ah from an old emergency/power failure florescent tube light the other month, I am sure it will work but it does seem somewhat low (especially with the extras you are adding in there).

On the other hand I did once watch a couple of the Beverly Hills Cop films:

Who cares if it has no use at all. Its freakin bluetooth. Every electronic device should inplement it in one way or another. :creep:

    truth be told, i agree with psi, i dislike both candidates, but i'd probably vote trump simply because the economy was better during his presidency
  • AngryCinnabon @ AngryCinnabon:
    Just be careful, if trump ends up winning and using project 2025 America might really change...for the worse.

    I'm not american and even that sends shivers down my spine.

    anything that offers trump an opportunity to become an actual dictator
