Nano Pocket Mood Lamp (USB)(Attiny85)

About: Just a Small Tinkerer ;)

Hi Everybody,

Rainbow Contest was here and an idea was also here in my mind... :D

I Made my Own Nano RGB Moodlamp ..which directly connects to your phone charger pin.

and just of size : 20mm x 15mm

Cutting Etching and Making PCB was all done by me but i would give a special thanks to "xBacon" in this instructable family. His code was Awesome and was 100% Compatible in my project.

My Idea was based to make a Pocket Friendly MoodLamp which would be plug 'n' Play.

After all, My Attempt was Successful and i am really happy with my pocket Lamp.

Message me if you want to buy a kit of this .

Boards would not be made by me for Quality Reasons*( will be manufactured by a Company)

Payments could be processed by paypal on my website : (Developmental Stage.)

Do Vote me for " Rainbow Contest" and "Bedroom Contest" ....

Step 1: Gather All the Parts

So Let's Start Making this :

Gather all The Parts to make this Projects:

1) Attiny85 ( Main Part)

2) Copper Clad PCB

3) 68 Ohm SMD Resistor (0805)

4) 1 RGB 5mm LED (Common Cathode)

5) USB Connector Micro - B

Step 2: Schematic

Schematic was Copied from xBacon's Instructable.

Thanks to Him,

This is a Very Simple Schematic.

Step 3: Eagle Board File

Step 4: Attiny85 Code

I Have attached the Attiny Code.

Step 5: Printing Artwork

This is an very small Print,

Do check for any error after transferring artwork

Do Remember to Mirror it.

Step 6: Etch It!

I Used Ferrous Chloride others are your choice...

Step 7: Drill Holes for RGB Led

Holes might not be that good (just because my drill bit got flat :| ) but it worked .

Step 8: Solder USB Connector

Now, Let's Start Soldering Parts.

This is my first such small smd soldering project so Excuse me for any mess....

So , First we Would solder USB Connector Micro,

I Didn't got any Problem During Soldering this just before i was to solder only VCC line and GND line of the connector.

Step 9: Solder SMD Resistors

Solder 68Ohm SMD Resistors

Step 10: Solder 5mm RGB Led

This was an tricky part...just because traces were too small.

Step 11: At Last Program & Solder Attiny85

I used my Custom shield to program attiny .

Make sure Attiny85 pins dosen't get short with each other otherwise it would be fried.

Program could be found in above steps.

Step 12: Finished!

Now take this Light were ever you go and attach it to your phone charger to make it work!

I Hope Everybody Liked it :)

Do Message if you want to buy -- i will tell you a estimate of shipping charges according to country and price of the kit too.

    The common good etchant is either Ferric Chloride or Hydochloric acid + Hydrogen Peroxide

    This is great! I've always thought it would be awesome to make something like this that's just a coupler that you leave on the end of your charging cable. That way with it's dark at night you can easily find the end of the cable.

    Amazing idea!
    But RGB would be neccessary then and it would be much smaller size...
