List of projects started or TODO:

- Arduino Blindshutter (half made but then left it because it was boring, may get done it one day)

- ESP8266 boards. Problem at the moment with USB-RS232 adapters. Lack of power shouldn't be the issue. CP2102 chip couldn't just get to work for some reason. No "AT" and "OK" for that message. Responses are just "AT" and then "AT" when power is taken from external 3v3 source.

Embedded devices owned:

- Embedded Linux computers (and accessories):

  1. Raspberry Pi rev B (512 MB), Found out to be reliable and robust when system is on USB 3.0 drive (SanDisk Nano). Can be "maltreated" every day with power disconnection etc. so far no flaw with that solution. Boot sector only on SD-card. Will use that setup for my purposes. May consume more power but is really reliable and has not corrupted under "maltreating power-offs".
  2. 3.2" LCD touch screen with SPI-interface. Not yet used that but will do. Kiosk mode of a small sensor etc. data web page could be driven already on the screen I think.

- Arduino boards owned: (clones)

  1. Arduino nano *2 (5 V, 16 MHz) (AtMega 328P), one modified for the blindshutter.
  2. Arduino pro micro (5 V, 16 MHz), same model as in the sparkfun. Uses AtMega32.

- ESP8266 models owned:

  1. ESP-03,
  2. ESP-04,
  3. ESP pin lead out (white 4 x in size of the bare ESP-04 module, but ready breakout and brilliant PCB layout)

ESP-03 and -04 were soldered on: (http://www.ebay.com/itm/270720154575?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) 0.5/0.8mm TQFP QFP/FQFP/TQFP32,44,64,80,100 to DIP Adapter PCB SMD convert

* ESP pin lead out (http://www.ebay.com/itm/391003246162?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT). That is really handy.

Sensors:

  1. Dallas DS18B20 (1-wire sensor, temperature, Really good and reliable!)
  2. DHT22 (humidity+temperature sensor, not yet tested)
  3. LD-resistors for light intensity measurement stuff (works as should)
