Introduction: Blinking Penguin
The board comes in the form of a DIY kit - if you like soldering this is the FOSDEM-85 package suitable for you! FOSDEM-85 is a very tiny - Arduino-inspired board. It is built around the well-known Little wire design and uses micronucleus boot loader. The same design is also used for the Digispark and Adafruit’s Trinket. The microcontroller comes preprogrammed with "micronucleus tiny85" that is suitable for use with the Digispark's Arduino distribution.

Step 1: Install Resistors
Step one is install the resistors
Insert R1 and R6 first , values are 10K/0.125W (Brown,Black,Orange) for both resistors. Then solder the legs and clip off the legs close to the solder joint.
Next insert R2 and R3, values are 1.5K/0.125W(Brown,Orange,Red) for both resistors. The solder the legs and clip off the legs close to the solder joint.
Next insert R4 and R5, values are 22R/0.125W(Red,Red,Black) for both resistors. The solder the legs and clip off the legs close to the solder joint.
Step 2: Install the Diodes
Next Step after installing the resistors it to install the diodes. there are 3 diodes to install D1,D2,D2 (1N4148/D035). Solder and clip off the legs near the solder joint.
Beware of polarity. Align the black strip on the diode to the black strip on the board. if you put in the diodes the wrong way round nothing will work.
Step 3: Add the IC and USB Port
Next solder in the IC , observer the polarity of the socket as you need to align the semi circle on the socket with the semi circle on the IC drawing on the board . If you get the polarity wrong you will damage the IC.
Next add the USB socket and solder to the board, once done you can move on to add the capacitors.
Step 4: Add Capacitors
Next we are going to add the capacitors C1, C2 values are 10uF/16V for C1 (this is the electrolytic capacitor)and 100nf for C2. When inserting C1 you need to observe the polarity otherwise you will damage or destroy the capacitor. The short let is the negative connection and the long leg is the positive connection.
First insert C1 (observe polarity) , solder and then clip off the legs near the solder joints.
Next insert C2 and solder and then clip off the legs near the solder joints.
At this point you can also solder the battery connector to the board. Also solder the pin headers to the bottom of the board these will allow the penguin to stand up.
Step 5: Mount the LED's
Mount the LED's onto the board (they go on the reverse side to all the other components). these are components which polarity needs to be observed. the short leg is the cathode, and the long leg is the anode.
orinate the legs of the led that the cathode matches the flat side of the led drawing on the front of the penguin.
Step 6: Plug in Your Penguin.
Plug in a lipo battery into the battery connector and the LED's will light up , one will be solid on the other blinking.
