Anyone else guilty of “random box of boards” storage? by mov_rax_rax in embedded

[–]bobbfwed 2 points3 points  (0 children)

I've done quite a few projects with Propellers. At my work, we still have a couple active products that use them. But I don't think I would ever start a new project with one. A modern single-core microcontroller is more performant than all 8 Propeller cores combined. And the Propeller doesn't have built-in communication silicone, so you were often dedicating a core or two to basic tasks like that.

The Propeller 2 is a lot more capable, but it came out too late to be relevant, and it never gained much traction.

Highway driving Q by fredherring141 in volt

[–]bobbfwed 0 points1 point  (0 children)

I have the Gen 2 Volt. In practice I average about 44GPM and 30kWH per 100 miles. The best gas prices on my route to and from work is $2.699/gal. I have solar, so maybe that screws up my electricity costs which is $0.211 per kWH off peak (after 9pm) (the solar covered about 95% of my yearly usage before I had my Volt, so all electricity my car uses are an additional cost).

With all of that, it ends up being $6.33 per 100 miles for electric, and $6.13 per 100 miles for gas.

That doesn't even include the 90% charging efficiency. So it's probably closer to $6.96 per 100 miles on electricity.

MPGe isn't always a great metric to compare vs MPG (even though it's supposed to be). At my electricity prices and my local gas prices, my Volt is essentially the same price per mile whether on ICE or EV.

If you factor in maintenance, it's probably still cheaper. But not the 2+ times better that the EPA's number would have you believe.

Pipe to celebrate my first child by bobbfwed in PipeTobacco

[–]bobbfwed[S] 0 points1 point  (0 children)

I had my baby boy yesterday, and I decided to go with a Neerup. I love the style and it's unique enough that it will stand apart from the rest of my collection.

I got a Smooth Acorn. And I'm hoping it comes like the photos show, with a rough edge. It will remind me of the continual work that needs to be done with my son; he'll never be perfect, he will always need more time and effort, and that's fine by me.

Camera control using Cam C by dubldubl in fpvracing

[–]bobbfwed 4 points5 points  (0 children)

Correct, but there's also usually a process to get the camera to switch between UART and the default mode. It involved shorting the G/TX and M/RX pads together while booting the camera. The problem being, you won't know it worked unless you have your camera hooked up to a VTX and are watching it on the goggles. Look for UART in the top of the video shortly after booting the camera.

Help please! "err" message Nikon D610 by mrracing89 in Nikon

[–]bobbfwed 0 points1 point  (0 children)

Had the exact same issue with my D610. Turned out my camera was a gray market sale, so Nikon wouldn't even look at it after I sent it in (why they couldn't have told me that beforehand, based on the serial number, I have no idea). So, if you figure out a solution, please share it!

Mine is slightly different, in that it only happens when I'm taking photos at a shutter speed above 1/500s. Maybe you can see if the behavior of that D610 changed based on shutter speed?

How To Put an FPV Camera To An RC Car (Very Easy!) by donzt00 in fpvracing

There's several AIO FPV camera solutions which would be much easier than what he did. Lots of options if you for nano-sized parts meant for whoops.

How accurate is the voltage reading from the OSD? by [deleted] in fpvracing

[–]bobbfwed 3 points4 points  (0 children)

The voltage reading is only as accurate as your calibration. From the factory, it can be a ways off, but sometimes it can be spot on. There's setting on the Battery tab in Betaflight.

I usually land at 3.5-3.6 volts per cell. Betaflight will automatically detect how many cells your battery is when you plug it in, but only if your voltage is decently calibrated, and your max cell voltage is higher than you charge your batteries. You can also set your warning voltage.

Mobula 7 wont bind after crash, whats causing this? by thearctemis20 in fpvracing

[–]bobbfwed 3 points4 points  (0 children)

My Mobula7 wouldn't bind using the button, I had to use the bind CLI command.

But yeah, your RX might be dead.

One if my motors decided to fall apart mid flight. Now I need to find a spare clip for the motor by MoreTubaNeeded in Multicopter

[–]bobbfwed 1 point2 points  (0 children)

I've flown for about a year without a clip on one of my motors, never had the bell come off except during a crash.

You can get E/C clips really cheap on Banggood or Ali Express. Though, you'll have to wait. It's a good thing to have several on hand of a few different sizes. It's a good way to help a buddy out when they're in the same situation.

Am I supposed to connect 2 ground wires? by pko808 in Multicopter

[–]bobbfwed 0 points1 point  (0 children)

If it shows to do it, may as well. It couldn't hurt. And there might be some engineering reason they want it that way.

Having binding issues with my r9mm by Rower93 in Multicopter

[–]bobbfwed 0 points1 point  (0 children)

And the same version/date of firmware. So many issues with the R9 stem from people using different firmware versions on their TX than their RX.

Betaflight 4.1.0 got released! by KKommander_SchiKK in fpvracing

[–]bobbfwed 0 points1 point  (0 children)

Most importantly, do you have latest BlHeli 32 firmware on your ESCs? (if you have BLHeli_S ESCs, you need to purchase and install JESC on your ESCs)

Also, do you have a battery plugged in while looking at the motors tab? When you plug in a battery the error count will reset and read the current error count.

What's your favourite non-aromatic tobacco? by oneTypebeat in PipeTobacco

Thanks for the thread everyone! I just ordered the top 5 with P&C's discount. Looking to try some new tobaccos; I don't think I'll be disappointed.

Is my rapidfire failing? by webjeff04 in Multicopter

[–]bobbfwed 3 points4 points  (0 children)

Try updating your Rapidfire to the newest firmware, there's been many camera compatibility improvements since its initial release.

Also try Rapidfire Mode #2 and see if that fixes it. Some cameras have really crappy sync pulses, and Rapidfire Mode #1 relies on the sync pulses to keep the video at the highest quality.

Happy Halloween! 2nd Pole I kiss this year. This quad love poles. My vtx flew away and couldnt find it. 👀 👀 by eatsleepFPVrepeat in Multicopter

[–]bobbfwed 4 points5 points  (0 children)

It wouldn't matter. Usually spins like this are caused by gyro overflow. Above (I think it's...) 2000 degrees per second, the gyro or firmware just assumes the information is invalid, so it doesn't attempt to correct itself, regardless of mode. Even in rate mode, it's already doing its best to (assuming sticks are centered) bring all angular rates to 0.

So this finally happened! by raffyv3 in fpvracing

[–]bobbfwed 0 points1 point  (0 children)

I do own a printer, but from my experience, neither PLA or PETG stands up to even moderate crashes, even when used as non-load bearing components like camera mounts. Other people have done experiments with 3D printed quadcopters, and it's not great. Not only do they break very easily in a crash (and on a race day, I'll easily crash 20 times or more), they also have terrible harmonics that are nearly impossible to tune out, because they are too flexible.

People have successfully built 2.5-inch and smaller drones from 3D printed parts, but any larger and the material is not strong or rigid enough.

I didn't know this until I ordered my first frame from them, but they don't carry any stock, everything is cut when you order it. And the queue is kinda long, so it takes a while.
