    Inertial Measurment Unit (IMU) Selection !

    I don't think you are going to find one that small. https://www.xsens.com/products/mti-1-series/?gclid=Cj0KEQjwnMOwBRCAhp-ysqCwypkBEiQAeSy1-cMjzcRf_lrLezCFBEXskrLQWEQt6RbCqOWzqusxNEcaAu3j8P8HAQ

    Variable resistor separate from control circuit?

    For phase cut control you could use a opto triac driver, but your micro would need to have a zero crossing signal to set the phase. How is the micro being powered?

    Relay Behaving Strangely

    Check by operating the gate remote manually to see if it blocks the receiver.

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    Yes and a ULN2003 to drive the segments.

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    http://www.onsemi.com/pub/Collateral/MC14511B-D.PDF For example. Connect all the data lines in parallel and the latch to separate pins. To change a display put the data on the parallel bus and toggle the latch pin for that digit. If you are using a bit of power you may need segment drivers. Info...

    Help with open collector output

    I'd still dispense with the relay and drive the motor from the receiver.Just measure the voltage on the output driving a known current and you have the on resistance . Unless you are driving a large load it will be negligible. I'd expect it to be ~ .025Ω So would I as above

    Heating elements for own built terranium

    I think you have answered with the one you bought http://www.ebay.co.uk/itm/221810230062?_trksid=p2057872.m2749.l2649&var=520676661904&ssPageName=STRK:MEBIDX:IT You can see the heatsink, there are a few available...

    Need Help Improving Brightness in Multiplexed 7 Segments (6 Digits)

    You could multiplex BCD to 7 seg latches and thereby drive the display statically. This will require 4 data for all digits plus 1 latch for each digit.. Show current schematic How many digits? .How much current and voltage per segment?

    Heating elements for own built terranium

    The triac package (TO218) suggests to me that it is capable of more than 1kw, without knowing the number.. Add a small heatsink and you'll be ok And its cheaper unassembled

    Help with open collector output

    The 16V is max gate voltage. Threshold is .8 - 2.2V Easily switch several amps at 5V. Rds on .05Ω at 4.5V (each). Looks like they are wired in parallel Given that the min supply voltage min is 7V I think the output is 5v

    Heating elements for own built terranium

    You need to control the input to both elements. Do you know the current they draw? You could use phase control https://en.wikipedia.org/wiki/Phase-fired_controllers Like a incandescent light dimmer I tried searching for an integral cycle controller but without success seems unavailable now...
