im making progress with the BiCopter, ive got it flying level for the first time, im also wanting to buy at least one floor bot Lidar, and i plan to start etching a board soon for the DLIS-2k.
and how is your going? which optical component are you using? i may switch to a cheaper one for initial testing...

My lidar project is temporally stopped now. I decided to make another lidar with simplified and more strong mechanics and with iC-LF1401 sensor (it's also has 128 pixels, but it has better sensitivity). iC-LF1401 sensor is easy to buy, so I want to create simple DIY lidar. Now I'm waiting some parts for it. I refused of using ELIS-1024 sensor, because it has too big analog bandwidth. DLIS-2k is very difficult to buy, I have information then one sensor cost more then 45$ and the minimal order quantity is 10 pieces.
About optics: Now I'm going to try simple objective from small security camera - like this one: link In fact it's not very good for iC-LF1401 sensor, but I hope that it would be suitable enough.

if the sensors are slow or expensive, i dont now what we will be able to do! we need to talk about optics too, i was hoping to use simple optics, like a single lens...

Have you seen this project: ? They have already done a prototype with good characteristics and want to start production. The only question is the price - they did not give it.

How are you progressing?
I now posses two XV-11 LiDARs, and will use these in the competition in this august, I will continue to build a superior device for use (hopefully) in august 2014's competition.

I was hoping you'll be building one from scratch
yes I will have too sometime after august 2013, maybe early 2014. I think ill need greater capability than the XV-11 can provide sooner than I first projected.

hey, does any one know fast linear photo-diode sensor ? 128 or 65 points, with 8-20MHz readout CLK. for now i use TSL1401, and i get 58KHz read speed with FFT, but i need to be able to get 100-200kHz cycle speed. Best what i was able to find is this: But i can't get, can't buy, or get samples and fastest for 128 pixels would be CCD , but it will be expensive to drive (ultrafast multiplexing opamp for single adc readout, and CMOS to MOS logic level convertion is tricky (3.3 to 12V at 10MHz)
