Thoughts on the “essence”
First you must follow your own nature, if you are natural and firm in your beliefs yet flexible in the way you encounter life, then your spirit will inhabit the blade and make it perfect
Yosihara senior on the Japanese sword
– Searching for the essence gave japan advancement in technology and miniaturization.

Canotto, building an electro-acoustic upright bass!
Reply
My friend who is a bass player came up with an idea of building an upright bass. After going through a lot of ideas and designs we stumbled upon the Canotto.
A beautiful canoe shaped upright bass designed by 19th century French physicist Felix Savart.
Here you can see how we build it in 9 days with basic woodworking tools.

OLED LCD I2C test
Today I tested a small 0,96″ OLED display with 128×64 pixels.
It is a common SSD1306 display with I2C.
The hook up is easy:
Display -> UNO
SDA -> A4
SCK -> A5
GND -> GND
VCC -> VCC (5V)
I use the MultiLCD library, which works fine.
The OLED display I bought for 2,69 $

Bootleg Mic
Ever felt a need to record a concert or your band on your phone, since no other recording device is available?
Well I found a wonderful solution over at Open Music Labs. A simple electret microphone upgrade for your phone! I added a -20dB pad switch by adding a 3k9 resistor in series on output. That provides plenty of attenuation, I have to try it with our crazy loud drummer, sometimes when he bangs pieces of cymbals go flying…
another build can be seen here: bootleg mic
After some time I decided to mod the mic for more gain, now it works great! I used 1k5 instead of the 470 Ohm resistor. The gain of the microphone depends on the quality of the capsule and the JFET used and probably the cell phone, so the gain mod described here is sometimes necessary, like in my case.
Gain Mod – The gain of the stock bootlegMIC is set to 0.2, based upon tests with a few cellphones. Our testing was by no means exhaustive, and it is very likely that the gain may be too high or too low for your phone. If you want to tailor the gain specifically for your phone, take a recording in the loudest setting you think you will want. Next, open up the recording in a wavefile editor so you can see the peak levels. If the signal is lower than 0dB, make a note of the highest peaks. If it is higher than 0dB, estimate how high the peak would be. Then calculate the difference in gain needed. For example, if the signal is down by -6dB (one half full scale), then you should double the drain resistor value (make it 1k). If the signal looks like it is +6dB too hot, then half the value (220ohms).
