After my initial idea for this summers project got stuck, I took out the list of many little projects I wrote down over the past year.
This thread will house a bunch of them.
perform sanitychecks = false; do burn_fingers = avoid; enable soldering_iron = true;
1 - LED-Christmas tree
Description: A cheap little USB christmas tree. As the original LED did not have a resistor, the one it came with burned out rather quickly. My instant fix was to solder some resistor that was in range of beeing the right one to it, and a blink cycling LED…
The idea: Replace the blinking LED with an RGB LED, attach that to a micro controller and programm it pretty.
|ATtiny85||1||Cheap, simple, works|
|150 Ohm resistor||1|
|56 Ohm resistor||2|
2 - Battery LED Lamp
Description: LED light with an odd flickering quirck. I suspected the switch to be the cause (it is not), faulty wires are ruled out, a capacitor tacked accross the aray did not fix it…
The idea: Replace everything except the housing. New LED array, new switch, charge controller, battery.
|Switch||1||I do not trust the switch!|
|Battery||1||500mAh, should result in 3 hours on time|
|39 Ohm resistor||1||>2W|
|Adafruit 1904||1||Link, it is a charge controller|
3 - BananaPi SSD NAS
Description: My mother and sister (sometimes me) are exchanging quite a lot of small files, be that single music tracks or a hand ful of photos. Right now, that happens via handing arround USB drives.
|5V 2.5A wall adapter||1||Or do I need 3A|
|Banana Pi SATA cable||1||curious how this works|
|Banana Pi case||1|
|ADATA SU 630||1||Unsure about capacity, 240GB, 480GB|
4 - Illuminated base for etched crystal
Description: I got one of these laser etched glas blocks similar to this. I want to give it an illumated base to rest on.
The Idea: Wood base with one or two LEDs in it, maybe light blue and amber?
|3mm ww LED||3||One spare|
|56 Ohm resistor||2|
|3m micro USB cable||1||Costs nothing, so better have one spare|
|microUSB breakout PCB||1||Makes soldering to it easier for 20ct more|
Some user input would be nice. Especially on the Banana Pi NAS.
All else is good to go as is.
