RE: Spectrography using the epc901 High Speed Line Image Sensor

Nice project! Where/how can I order the circuit boards (the adapter board and the breakoutboard)?

Hey Frank, super interesting project. I know it's been a while since you posted but I was actually thinking of building one of these. I think an interesting application is using it to identify the physical properties of objects. Maybe coding the sensor to recognize certain wavelengths being a specific material.

Hey [mention:65f941a681d84fe68670ebabb2cfde44:e9ed411860ed4f2ba0265705b8793d05]

could you provide me the link to the product used above product(small case and an Orange magnet holder)

Thank you in Advance,

Hi fmilburn,thank your team desgin and share EPC901 spectrometer ,this great project for me.I am repeating this project. I want to know whether the frame rate of epc901 can really reach 47khz (FPS) mentioned in the data manual, which is very important to me. Thank you

Maybe Shawn's tutorial can help you out to finish the project [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-50b97f1f-87a8-4d52-bda5-d0b5cd72e518/contentimage_5F00_2516.png:16:16]

RE: Sensor Kit For BRACCIO

Nice build.

I see that you could use a lot of feedback sensors plus some acceleration and decceleration control loops to smooth out the movements and to allow you better sensitivity control.

Overall it was a good looking first test.

Very impressive project well documented.

Nice post.

About thirty years ago we used the same technique with GPS to improve accuracy and reduce atmospheric issues.

I like this device as I have always wanted to know more about Hall sensors and this type of project is something that is interesting to me as it could be used in mobile robots, especially for outdoor mobile robots where being able to seal the body of the robot to protect against weather is a good idea.

I looked up the device and it seems to be wildly variable in pricing from suitably cheap to way to much money. I have selected a couple of the suitably cheap ones, hopefully they will be OK. Would you be able to provide the STL files for the 3D printing - I could make my own but it probably wouldn't be as good as yours. Also, it isn't clear to be, does the magnet fit into the top wheel part and rotate above the sensor? Is it some kind of special magnet?

A good project.

RE: Light up Coaster using sound sensor

dubbie — Tue, 17 Nov 2020 10:43:39 GMT

A really great project. I particularly like the idea of a light-up coaster - could be a Christmas present for the person who has everything. I might have a go at making something like this, but possibly without the sound part and maybe with a battery of some sort rather than a USB connection.

One thing I forgot to add to the blog was the custom gripper I designed, inspired by the design of a gripper I will be using at University for a project. Here is a picture and 2 short videos of it. I'll go into more detail about it when I have completed it in a separate blog post!

RE: Cat Detector Using Sand #3 : The Results

beacon_dave — Mon, 16 Nov 2020 19:55:10 GMT

"...The use of tyres for an external mobile robot has problems due to slip caused by sand as well as wet surfaces so for future outdoors mobile robots I will have to have a think...."

That was quite impressive for wet sand.

Perhaps you could have a height adjustable grader blade so that when traction is about to be lost, the cut depth on the blade is reduced and the job completed with multiple passes ?

I guess that you could do similar with a spring loaded blade such that it starts to deflect before traction is lost.

A heaver battery would probably also help with traction.

genebren — Mon, 16 Nov 2020 19:53:57 GMT

Nice job! It is good to see that your system was able to survive the elements. Keep in mind that wet sand is a lot more difficult to move than dry sand, so some stall/slippage is to be expected. You might be able to roughen up the wood (add texture) to give your tires some to grip on. They make non-slip tapes to add to stairs and such that you might be able to apply to the upper edges of your sand box.

Keep up the good work!
