China electronic components integrated circuit spot distributor--ICGOODFIND

Interting. Thanks.

This is very basic stuff, no sense to watch this video

What is the board that can connect to it

Creative, thanks :)

what pcb manufacturer do you use ? the boards look very clean

Good job! Love your videos, keep fighting bro.

Idk how to make IMX 383 work😂

Better off opening with a butter knife if you have nothing else. Don't cut yourself.

Seems likely that it’s a Silicon Labs EFR32MG21 Series 2 Multiprotocol Wireless SoC.

Could you make one for the QMTech module such as Kintex 7?

Great!

Excellent work. How long did it take you to do this?

just kinda showed up in my recommended but nonetheless neat! thank you

Please make series on embedded engineering ❤❤❤

extremely impressive!

Awesome :)!

How has this channel not gone viral and blown up?

Awesome work!

*LT3042 Ultralow Noise LDO Regulator Performance Evaluation* * *0:00** Introduction:* The video focuses on evaluating the performance of the Analog Devices LT3042 ultralow noise linear regulator, specifically its line regulation, load regulation, and noise characteristics. This evaluation is part of a project to build a precision voltage reference using the LM399. * *0:35** Target Application:* The LT3042 will supply a stable 15V to the LM399 voltage reference circuit. * *1:18** Test Parameters:* The video focuses on verifying the LT3042’s line regulation, load regulation, and noise performance against its datasheet specifications using a limited set of instruments. * *5:55** Line Regulation Test:* * The input voltage is varied from 2V to 20V while the output is set to 1.3V with a 1mA load. * The output voltage variation remains within the datasheet's maximum specification of 3µV/V, indicating good line regulation. * *11:38** Load Regulation Test:* * The input voltage is kept at 2V and the output voltage (1.3V) is measured while the load current is varied from 1mA to 200mA. * Initial measurements with longer leads showed a drop exceeding the 0.5mV maximum specification. * *Directly probing the regulator's output pin showed a voltage drop within the specification, highlighting the importance of minimizing lead resistance in low voltage, high current measurements.* * *17:09** Noise Performance Test:* * *The noise level of the LT3042 is too low to be accurately measured by the Keithley 3400B RMS voltmeter.* * A spectrum analyzer is used to measure the noise floor at the regulator's output between 10kHz and 100kHz. * The noise floor is significantly reduced at the output compared to the input, demonstrating the regulator's noise suppression capabilities. * *22:48** Conclusion:* The LT3042 performs well in terms of line and load regulation and exhibits a low noise floor, making it suitable for the intended application in the precision voltage reference circuit. I used gemini-1.5-pro-exp-0801 on rocketrecap dot com to summarize the transcript. Cost (if I didn't use the free tier): $0.07 Input tokens: 19708 Output tokens: 490

Nice video, keep it up, thank you :)

could this be done with other sensors like the IMX290 or IMX533?

Great work. Just wondering how did you manage to solder image sensor which (I think) is extremely sensitive device?

So you essentially wrote your own mipi csi driver?? Wow

Absolutely INCREDIBLE video. Thank you SO much for such a clear explanation. Much respect to you, young man!

I think since all of these pieces of test equipment have a 10MHz reference input I would simply get a used cellular base station GPS timing card and use that for the entire lab. They have a OCXO on them that is locked to GPS and thus are far more accurate than a stand alone standard like the inbuilt one you added. The added plus is that all your instruments are all on the same timing page.

This is a very difficult job. You are an expert. I sent you a personal email

Hi did you implement the debayering for this yourself? I have been trying to use the V4L2 API to get the raw bayer frame (which I'm able to) but can't seem to get the debayering right. I've tried doing cv::cvtColor(bayer_frame, rgb_frame, cv::COLOR_BayerRG2RGB); after bitshifting for RG10 but seems to get artefacts I can't figure out. I'd appreciate if you could point me to the theory of your pipeline. Nice work btw.

Sir please make a video on FPGA and fx3. How they are connected to camera sensor, it will help me to understand. Actually I want to make my own camera for UAV

WOW! DIDNT EXPECT SUCH A AWESOME VIDEO

Is it possible to get JPEG output? Would like to use this for an application that only supports JPEG.

a ERO memocal can do the same and can be found quite cheap nowadays on ebay. only thing they all have in common is that horrible membrane key pad

Been hoping someone would build a modern analog multimeter with built-in ESR tester. I seen them available online but none of them will ship to the USA

This is awesome! any chance for a simpler design being offered that just plugs directly via USB and acts like a webcam? Kinda like those cheap ELP brand CMOS cameras you see on aliexpress that have a plastic lens c-mount on the pcb. I'm looking to build my own to fit my assembly and can't really use any off the shelf solution.

Really curious to see how you do the AWB and AE (working on our own camera design, not dissimilar to what you are doing, and I'm finding making a robust AWB to be a very interesting challenge)

can you make a small playlist/video , on how to select Camera sensors, and make a module out of them , specially using M-Cortex MCU and FPGA , I know FPGA will work better , but I think making a custom camera module using commonly available MCU like RP2040/ARMCortex-M7 / Xtens LX7 Dualcore/ etc; as this kind of content is not present, atleast as a playlist on yt, you will get a good reach, and students like me will learn a lot. Great Content Sir 💯

Brilliant video. Thanks for taking the time to create and post this content.

Great! Thanks for share

This is really impressive did you draw from another open source project.

Can you make a video on Multi camera (3 or 4) through mini coaxial sync connected to Jetson or other MPU boards ? The problem with MIPI CSI 1/2 is length of cable and USB is BW limited and power hungry. Coaxial or GigaE are possible solutions which am considering for my project but the cost of Serializer and DeSerializer is beyond budget. Hence can you suggest OR make a video on solution with Multi Cam Sensor connected to small Application cores - or all camera Sensors connected to same App processor ? Thanks and great channel

I want to appreciate you for the effort in the Camera and FPGA interfacing. The work gives me hope that I can handle similar work. Please advise me on how to go about this task; I wish to have a camera with FPGA and DDR3 RAM, the interface should have an Input and Output trigger (End of Frame) signal. I don't mind USB 2.0 or USB 3.0. I want it to work such that an external signal from another board will be used to trigger the sensor to start a frame grabbing. The sensor should be the type with adjustable integration (exposure time).After a complete frame is captured, the output trigger should send a signal to the external circuit. and then the frame data can be read. I don't need high repetitive speed, rather a very high frame grabber speed in the range of 1us or less.

Very elegant build

Wow. This is an underrated channel. Such high quality content. Very well done!

The LM399 device is already temperature stabilized and thermally insulated, so the foam is unnecessary. The buffer circuit is where you may find a greater variation with temperature. Using temperature stable high accuracy resistors is a good plan, perhaps using a temperature controlled box for a stable voltage divider.

Hi , this is a very good and detailed project. You have motivated me to try such project. Im trying to read the dsi data by an osilloscope. what model and spec oscilloscope did you use in this video. I have a 100mhz Rigol. would that suffice? The lane speed of the dsi im trying to read is around 940mbps.

Woww!! Great work!! Thank you for sharing the work and knowledge!

I love this so much! You do such a good job explaining such a crazy complex board! Can't wait to see more!

Thanks for the great project @CircuitValley. I also saw your other projects such as the CSI2 receiver project and the industrial camera (CSI2) project as well. Question: do you have any idea if MachX03 is capable of doing CSI2-Rx and DSI-Tx at the same time? meaning would Macx03 is capable of interface to a csi2 camera, decode and demosiac/debayer, then send to a DSI display?

i wish i could buy this. one of the most incredible videos i've seen

Can you make a guide to create 1 PCB core using allwinner h3? Thank you very much😅😅
