Hi,
despite the wonderful description on CCD vs CMOS, I’m wondering what software do you use to write on?
Am I guessing right that you use it with a penbased graphic tablet?
cheers,
Christian
I use Camtasia Recorder ($300) + SmoothDraw3(Free) + a Wacom Bamboo Tablet ($80)
Hi Blake,
thanks for the answer. That you used a Wacom tablet was obvious since there is nothing reasonable else on the market.
Since I have to stay on Linux Camtasian Recorder is not an option but there are plenty of OpenSource tools that do the job of recording display actions quit well. SmoothDraw, version 4 now, is what I was looking for, because I couldn’t find any app where you can have a black background or more than two colors to choose. The only drawback is, that it’s written with .netframework and not with modern concepts like Python3x, os independant. Will be some hours of work with mono to get it running.
I have to say again thank you very much for your videos!
I used them for inspiration on some of my courses in my local astronomy group. I couldn’t show them directly, because the members don’t speak english. The way you explained how ccds/cmos work and what the differences are was most impressive to my group. I told them, where to find the material I used for the courses to hopefully direct them to your website.
Keep up the good work!
cheers,
Christian
Your Image Sensor video is great, Could you help to prepare a practical design example for cmos image sensor? which is from specification , simulation, layout to postlayout simulation. Thank you for your great effort!

I read a lot of interesting content here. Probably you
spend a lot of time writing, i know how to save you a lot of time, there is an online tool
that creates readable, SEO friendly articles in seconds,
just search in google – k2seotips unlimited content
I’ve just bookmarked this page, wonderful internet site!
Hi Blake,
I love your tutorials; however since you have no new material, do you know of any other tutorials similar to yours that cover the same material?
Thanks!
Hello,I log on to your blog named “My Tutorial Videos | ambientelectrons.org” on a regular basis.Your story-telling style is awesome, keep it up! And you can look our website about ????? ???????? ????.
Hey there, You’ve done an incredible job. I’ll definitely digg it
and personally recommend to my friends. I am confident they will be benefited from this site.
