Epic goal: To become an experienced electronics engineer.
Accumulate experience and knowledge for skillful use, repair and creation of electronics devices.
Goal Accomplishment Criteria
1) Be able to repair the devices (firstly own tools).
2) Be able to construct a device (including with MCU and own code).
3) Be able to get profit with this (bring benefits to society).
-
Buy electronic components for experiments.
Buy the
Suitable MCU's (ATMEL in my case):

Frozen goal: Creation of own soldering station.
-
Find a suitable scheme for printed circuit board.
-
Acquire a temperature controlled soldering iron.
-
Create an air gun soldering.
-
Acquire a pulse soldering iron.
-
Build a corpus.

Inventory my own electronic components.
I have some collection of electronic components (mostly Point-to-point construction). Also I have a lot of broken devices, eg motherboards (mostly Surface-mount technology). Please see the photos, I have attached.
I think, I need to do inventory all electronic components (which really will be useful in the future) of it.
I mean collect (do unsoldering, if required) and folded in the separate containers (with marks) and do record to catalogue (in DB, for example).
It will be practice for soldering, the study of types of components, also components can be use in future. Besides one can say it's 'housecleaning'.

Current goal: Create device based on simple Atmel MCU.
As MCU one can take the following types:
- AtMega8 http://www.ebay.com/itm/1PCS-MCU-IC-ATMEL-TQFP-32-...
- AtMega48 http://www.ebay.com/itm/1Pcs-Original-SMD-IC-ATMEG...
- AtMega88 http://www.ebay.com/itm/1PCS-IC-ATMEGA88-20AU-ATME...
- AtTiny13 http://www.ebay.com/itm/2PCS-ATTINY13A-SU-SOP8-IC...
- AtTiny2313 http://www.ebay.com/itm/1PCS-MCU-IC-SOP-20-ATTINY2...
I chose: ATMEGA8A-AU TQFP-32 ATMEL:
