Text not centered

i'm recording action , want text centred horizontally. won't it. pressing paragraph buttons shjoot text off side , seems based on intially type text in first place. must simplest thing on ps why won't text jump middle of photo? secondly i'm drawing selection around text (then filling black). there seems no way centralise selection box either. when run action on different sized photos box , text end in different places, separately. why , how can centralise selection too? select canvas (crtl+a) then, move tool activated, use alignment icons in options bar.

hallo ich bin neuling in sache rasperry und unix. erfahrungen mit pi-top zusammenbau: einfach und schnell die aussparung der rechten seite sollte dem raspberry pi 3 angepasst sein, damit der raspberry pi 3 ganz nach rechts geschoben werden kann und nicht immer das acrylblatt entfernt werden muss zur verbindung des usb oder netzwerks vorzunehmen. raspberry pi 3 b : es sollte auf dem board noch einen mini-usb anschluss für die tastatur haben. der lan-anschluss sollte um 180 grad gedreht sein. damit der anschluss besser ein- bzw. ausgesteckt werden kann. (das immer aus sicht für den pi-top) pi-top-os : beim shutdown schaltet das pi-top-os den raspberry 3 wirklich aus. die rote status-led ist gelöscht. das mitgelieferte pi-top-os basiert auf raspian. es ist nicht möglich direkt in den desktop zu star-ten. es muss immer das dashbord bestätigt werden, auf dauer nicht gerade schön ist. es hat auf dem desktop keine kontrolle über den ladezustand des akku. die hintergrun

Piezo element to Speaker

hey all, so question won't involve arduino directly. new electronics , wondering how can connect piezo element speaker (like car speaker). my speaker 8 ohm (i'm not sure how many watts, maybe 10?) , using 27mm piezo element. don't know if can use this, have 5v 10amp power supply older project: https://www.amazon.com/snanshi-10a-switching-supply-transformer/dp/b00xyynb78/ref=sr_1_2?ie=utf8&qid=1468406331&sr=8-2&keywords=5v+10a+power+supply basically want piezo pick contact sound vibrations , feed signal directly speaker, potentiometer or control volume. assume need kind of power source or amplifier make work. looking cheap because making around 50 of these! any advice appreciated while own research! thank much! typically you'll need 2 amplifier stages.   a preamplifier boost "microphone" signal audio line level (about 1v) , power amplifier drive speaker. you need experiments...    don't know how signal you're g

hey! i trying define variables reading i2c connection when stumbled accross seomthing strange... going fine until tried define variable called "b1": code: [select]   short ac1 = i2c_read(i2c_address, 0xaa, 2);   short ac2 = i2c_read(i2c_address, 0xac, 2);   short ac3 = i2c_read(i2c_address, 0xae, 2);   unsigned short ac4 = i2c_read(i2c_address, 0xb0, 2);   unsigned short ac5 = i2c_read(i2c_address, 0xb2, 2);   unsigned short ac6 = i2c_read(i2c_address, 0xb4, 2);   short b1 = i2c_read(i2c_address, 0xb6, 2); //troublemaker!   short b2 = i2c_read(i2c_address, 0xb8, 2);   short mb = i2c_read(i2c_address, 0xba, 2);   short mc = i2c_read(i2c_address, 0xbc, 2);   short md = i2c_read(i2c_address, 0xbe, 2); i got the following error message: quote error: expected unqualified-id before numeric constant  #define b1 1 note: in expansion of macro 'b1' i rewrote line several times, checked entire code errors , @ edge of punching laptop when got f***ing genius idea change
