Yes, it does look like the ELP 2 Megapixel USB Camera will do what you want. I brought up the DirectShow Properties GUI to change the default settings on my ELP 2 Megapixel USB Camera. For this camera, White balance and Exposure can be set manually or to Auto. The GUI also allows me to manually set Brightness, Contrast, Hue, Saturation, Sharpness, Gamma, Backlight Comp, Gain, PowerLine Frequency, and Low Light Compensation. I used the GUI to change all of these values to non-default numbers and then I unplugged the camera from my USB port. After waiting 10 seconds or so, I plugged the camera back in and brought up the Properties GUI again. The settings all remained at the values I had set manually. The GUI has a Default button to restore the values too. Best of luck with your project!

Comment on Manual Exposure vs Auto Exposure for ELP 2 MP USB Camera by ivdg https://makehardware.com/2016/06/21/manual-exposure-vs-auto-exposure-for-elp-2-mp-usb-camera/#comment-9885 Sat, 03 Nov 2018 10:03:39 +0000 http://makehardware.com/?p=548#comment-9885 Hi there,

iam using OpenCV and have the same issues you have with manual/auto Exposure. i want a camera that doesn’t auto adjust anything (exposure, whitebalance, brightness etc) AND remembers that after the camera is turned off. you use the ELP 2 Megapixel USB Camera. can it do these things?

also you asked about a programmatic way to set the exposure back to auto exposure. i added some options below.

hope to hear from you soon, i have a deadline comming…

vc = cv2.VideoCapture(1)
vc.set(cv2.CAP_PROP_EXPOSURE,-10)
vc.set(CAP_PROP_AUTO_EXPOSURE, 0 ); // off?
vc.set(CAP_PROP_AUTO_EXPOSURE, 1 ); // on?
vc.set(CV_CAP_PROP_AUTO_EXPOSURE, 0 ); // off?
vc.set(CV_CAP_PROP_AUTO_EXPOSURE, 1 ); // on?

int i = vc.get(CV_CAP_PROP_AUTO_EXPOSURE ); // you can check if it is the right value with ‘get’

// show settings menu
cap.set(CV_CAP_PROP_SETTINGS , 1 );

Comment on Teach your PC to fly a Mini-Drone! by Marko https://makehardware.com/2016/04/24/teach-your-pc-to-fly-a-mini-drone/#comment-7306 Wed, 25 Jul 2018 13:31:10 +0000 http://makehardware.com/?p=372#comment-7306 Hi there. First of all, I have to say that this is an awesome project.
I tried to test it out using JJRC H36 drone. But I have problems binding to it.
I used the original code from https://github.com/goebish/nrf24_multipro to supplement missing protocol for JJRC H36. Any suggestions on where to look on how to fix this problem?

Best regards Marko.

Thank you for suggesting WatchAir! It’s available on Amazon too – https://www.amazon.com/gp/product/B01LY2YX7I/ – out of stock on the white but for the price I’m good with the black. To have the HD antenna & dvr recording in one device is fantastic! It looks like it works with Apple TV & Amazon Fire Stick so I am hooked up with their app ok. I am thrilled to have cut the cord from cable, my Spectrum bill was getting outrageous! This definitely is a hidden gem in the cord cutting world. So glad to have found your post!

I’m wondering how you ended up going with the E010 in the end?

I know it’s an old project but i’ve made to make it all work (more or less).
I’d like to have a quick chat on some pars that I’d tweak to improve stability and performance of the drone trajectory.
Is there someone that I can ask to?

Thanks,
Christian

I resold it on eBay, making sure the purchaser knew that there was no program guide. Too bad. The price was right and the picture quality very good. Instead I purchased a ChannelMaster DVR+, now discontinued.
