Re: Which one is better? Platen's angle 100 or 90 degree?

According to your saying, is it better to use 90 degree angle because we can make a scanner shorter ( distance between platen and lamp)and save money? More farther, less lighter? Even though bigger angle can get more bright I have to move a light farther. More bright compensate will be reduced in a...

Re: Which one is better? Platen's angle 110 or 90 degree?

At 90 degrees the camera can see a reflection off of the adjacent platen pane. As you increase the angle between the two platen panes you can eliminate this effect. The amount you have to increase the angle depends on the field of view of the camera and this itself depends on the distance of the cam...

Re: My 2nd new book scanner!

If you're using a lightweight camera like a smartphone, why wouldn't you just mount the camera to the platen and then get rid of that tubing and camera mount hardware?

If you did this, you won't have to worry about moving/shifting books or changing scale factors at all.

Re: usb remote with HTC USB Splitter

Does your Canon camera support Live View over the video cable to an external display when you're photographing pages? I borrowed an Elph 160 and my splitter cable only outputs video when the camera is in Playback Mode (not Live View). From what I've been able to find out online, this is expected beh...

Re: usb remote with HTC USB Splitter

That is odd. The manual showed a separate port for an A/V composite connector on the A3300. Double check to see if that exists. If so, you should be able to plug in an A/V composite-to-element cable as well as USB at the same time. ... Hi Jonathon, The A3300 User Manual (PDF) mentions that this cam...

Re: usb remote with HTC USB Splitter

The audio signals are on the ORANGE and YELLOW wires in the splitter. If you aren't going to output the audio via an RCA cable then I'd suppose that you don't connect them to anything. I've made one of these for a Canon Elph 160, but I had video and audio RCA cable outputs, just as the author of tha...

Re: Original ~600pg/hr, very portable scanner now achieving ~900pg-1100pg/hr

What's the purpose of that cable that's threaded through the PVC tubing? Is that just to hold the individual pieces together?

i send an email on sparkfun for the HTC ExtUSB 11 Pin USB Connector with Breakout .
they told me that there is no more this type of connector in the market so they could not produce more.
The connectors are still available though. This may work if you're steady with a soldering iron.
