Super capacitor power supply Zero

-

hi all,

i wondering if it's possible power atsamd21g18 super capacitor.

i need couple of hours , if there's black out, otherwise samd powered power

supply.

i thought "black out detector"  :)  put samd in sleep mode until there's black

out.

hope explained well, if there no details..  ;d

thanks

there's spreadsheet powerstor says if want provide 10ma hour @ 2.5v 3.3v, you'll need 100j, should take 50f worth of supercap..  (that's ... lot.)  battery better choice (a cr2032 coin cell has 2500j capacity.)
supercaps still pretty lousy compared batteries; things use supercaps geneally recognize power failures , switch sort of low-current standby mode.  (a samd21 has standby consumption of 100ua.  @ rate, you'd need 0.5f last hour...)

Flip address is out of range arduino uno r3

hello  guy, trying flash firmware on arduino uno rev3 atmega 16u2 using atmel flip. whenever try , import .hex file program, throws error " address out of range ." have looked around online , haven't found solution. , info helpful. here hex file : https://github.com/nicohood/hoodloader2/blob/master/avr/bootloaders/hexfiles/hoodloader2_0_5_uno_atmega16u2.hex its using arduino uno hid Arduino Forum > Using Arduino > Installation & Troubleshooting > Flip address is out of range arduino uno r3 arduino

Arduino Uno not uploading

hi guys, so, have arduino uno r3 (not wired thing) when try upload sketch (even empty sketch) first takes long in "uploading..." comes error: arduino: 1.8.0 (windows 10), board: "arduino/genuino uno" sketch uses 444 bytes (1%) of program storage space. maximum 32256 bytes. global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes local variables. maximum 2048 bytes. avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x9f avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x9f avrdude...

Indesign and MathType fonts

-
i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
