Need project guidance on temp-fan project

-

hi everyone,

i'm looking set system project of mine. had considered raspberry pi told better way go. can help?

as bit of brief background, i'm security systems engineer trade. have basic knowledge of scripting languages jcl java , learn scripting languages quickly. i'm familiar electronics, great soldering iron, , design , build speakers , crossover networks in spare time.

here goals project:
i need board can connect 2 temperature sensors to. in addition, need board able connect 1 relay. coding involve flipping relay when temperature deltas met. need print 4 values display; temperature optionally, interested in connecting 2 simple backlit vfd displays report temperatures.

the remaining peripheral connections, can figure out on own. need display recorded temperatures on remote screen, assume via hdmi.

what need with:
- hardware need? (i reviewed picture thread showing need order, more specific recommendations).
- how connect temp sensors , relay? plug them straight in , let coding rest?

thanks in advance!

- hardware need? (i reviewed picture thread showing need order, more specific recommendations).
you listed out quite already.
two temperature sensors (which 1 depends on things expected temperature range, required accuracy, expected reaction speed, environment), relay (depends on controls, how controlled, environment it's placed in, required speed), display (dimensions, letter size, environment, brightness, etc), microprocessor. budget may come play.
when have requirements specified, narrowing down suitable kit quite straightforward.

follow instructions in data sheet of specific sensors , relays. depends on hardware used.

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....
