BREmote - DIY Remote

I have a Mateksys MicroBEC 12S.

I will check that. this forum is so rich that i miss some parts

I would highly encourage you to spend the money on the mateksys pro BEC. I had many issues with the smaller one and I think others on here have also. Since I changed all 3 of my boogies to the pro version I never have any weird anomolies. I also keep the BREmote RX board unplugged until after I connect the battery in case of a voltage spike to the RX board.

Basically you run the power into the BEC from the main power pad on the speed controller, one ground to the main negative pad on the speed controller, the second ground from the BEC goes to the small ground pad by the signal pad in the speed controller and the power out from the BEC up to the RX board. So the only thing going directly from the BEC to the RX board is the 5v power. The signal and ground come directly from the speed controller. Hopefully that makes sense and there is a few diagrams floating around, I know I posted on jdubs dual motor boogie topic if you search.

I have ordered 2 BEC Pro . Not very expensive

My display is slowly dying. Some of the cells on the display are weak or inactive.

It started after a poured a second ā€˜top-upā€™ foam, so can I just assume itā€™s due to poor connections that were maybe disturbed by the foam? The only way to fix is to open the Bremote and improve the display connection?

Could the foam have pushed the display out a bit? Can you try pushing on the display to see if it gets better?

Yea Iā€™ll try that, I also used 5 min epoxy around the display frame so will have to cut that first.

Hey BREmote crew!.. has anyone down here in NZ (or maybe AUS) managed to source a suitable magnet for the throttle and toggle? The N52 spec of the original doesnā€™t seem to exist on this side of the planet and the linked sources above donā€™t seem to ship to NZā€¦ I tried a slightly smaller magnet (closest I could get in NZ) and it is not grunty enough to give a reliable signalā€¦

Hi,
Just a question.
My Bremote shows the value of the foil battery and 0c.
What does it means?
I have no VESC just a normal ESC connected by PWM output of the receiver.

Many thanks
Stefan

0c = 0Ā°C ESC temperature
This feature only works with VESC
Solution: Disable #define SHOW_TEMP in the Tx config

All those settings are explained here

Very cool that you added the reverse functionality. Now I will give it a try. The new design looks also very promissing.Does it float by itself because it is so skinny? Thank you for sharing your skills with all of us.

People say that the PU foam is hard to get.
I found the Talamex PU foam on the Waveinn webpage.
It was about 20ā‚¬ and was shipped quite fast to Germany.
BTW: I have a lot of leftover. If You need some foam near Bremen, contact me.

I need one (or a few) bremote LR-receiver for my next tow project.
Is anybody in Europe/Austria who has one left and wants to sell it to me?
Or is there a ā€œsimpleā€/preconfigured way to buy at JLC?
Thanks!

I got a complete LR Kit

@Jesserosco Another question Iā€™ve only thought of now about remote calibration with BLHeli32 on dual motor boogies as I still canā€™t get it perfect. Do you calibrate each ESC separately or at the same time?

So I was careless when playing around with my dual motor tow boogie and plugged the ESC gnd/signal cable in reverse, now Iā€™m not getting signal to the ESC on the ā€˜10kā€™ side (after connecting it the right way). I havenā€™t checked for bad connections but in theory have I messed up here? What steps should I try to troubleshoot?

The BEC is still working outputting 5v?

I manually input the min and max throttle in BLHeli. I donā€™t use the throttle calibration.

These are the settings I use. I had to adjust the min throttle and then see if the motor would start going without any throttle applied and I quit adjusting it once the motor doesnā€™t move without throttle applied. It takes a few goes, but if you have the stock BREmote code these settings should get you close. I also adjusted the BREmote RX code as per @ludwig_bre instruction to get the tow boogie going as straight as possible by having my left motor start just a little earlier than my left because I had issues with them steering a little left.

To make fine adjustments to get them really synced up for your boogie you can add or subtract some to make it start sooner or later on the second motor using this line of code in the BREmote_RX file under the communication.ino tab line 130 on mine. I have + 15 for this one which makes the second motor start a little sooner than the first motor. If you want it to start later than you can have a - (minus) whatever number. Also something you will have to play with to get everything synced up to your liking.

Yes from BEC 5v before the 10k resistor and 0.3v after it.

Hmm, that sounds like the output has been damaged
Without power applied and with the ESC disconnected from the 2nd output, measure resistance between EMI and CAT pads (alternatively between signal and GND wire of the 2nd output)
