    Hobby Grade Laser Beam Profiler

    But in this way you will not be able to measure the beam diameter with the CCD. Also, how are you going to solve the line up issue from the image obtained by the CCD?

    Hobby Grade Laser Beam Profiler

    I don't know if the linear CCD would work though, since a lot of times the beams are asymmetric and with linear CCD you will only get the cross section of the beam. Unless youscan the across the beam. The filter issue is fairly easy to resolve since you can have a combination of filters so for...

    I watched the video, but I still don't know how you get to do the height map with the data from the webcam. :thinking:

    Hobby Grade Laser Beam Profiler

    Unfortunately after examining your image in Photoshop, the image you taken didn't provide a lot of information. The center part of the beam is basically saturated. You need to filter out more light.

    Peregrine 1.4 beta - Packed with new features!

    I looked at the data and looks like the Atomicrox's Peregrine seems to have some data been mark at same timestamp, but clearly is different data since the value is different. And this doesn't happened in Trevor's Peregrine. Perhaps this is due to the timer froze while the USB is still getting...

    Peregrine 1.4 beta - Packed with new features!

    Hmm... The CSV looks strange... Some of the entries have the same time stamp. I never have this problem with my Peregrine while I was testing the Cube. And according to Trevor the timestamp is done at the computer side. So I am not sure if it has anything to do with my firmware. The attachment...

    LPM In a Cube!! Bluetooth is Working!!

    Hey, I can make a converter board and send it to you with the replacement board. It only cost couple dollar, and besides it will look better. Show me how you want to mount your OLED. Also, I'll try to find some plastic bushing to put between the board so you can get rid of the header and get...

    LPM In a Cube!! Bluetooth is Working!!

    I am thinking about taking off the OLED header on the processing board and let the wire out between two boards. What do you think? Also I think I will be able to change display orientation in the firmware. I will make it changeable by sending command through serial. Sounds good? Thanks Wade

    LPM In a Cube!! Bluetooth is Working!!

    I have enough part to make a new one. I'll send a new board to you with no charge. And, yes it is the original board since it is a mature design and the only thing legging me behind was the firmware. In the meanwhile, the inductor still works even with a chipping. Just so you know, the inductor...
