The Quanergy website also no longer contains any information about the price of their modules, originally quoted at a ridiculously low 250$ (100k batch size), making me afraid that their product might be vapourware. Nonetheless, progress appears to be made in the area. The article states that "Google originally had to pay US $73,000 for each unit, itself a rotating array of 64 laser beams". Today a hobbyist can just buy an 1D LIDAR for 150-200$ or a 2D LIDAR for 450$ on seeedstudio.

> Today a hobbyist can just buy an 1D LIDAR for 150-200$ or a 2D LIDAR for 450$ on seeedstudio. If yer not picky, you can generally pick up a cheap "repair part" or "surplus" Neato 2D Lidar unit from ebay, for about $100.00 or so. They are generally pulled from broken Neato vacuum robots. Alternatively, a used Neato (or sometimes even a new one) can generally be had for under $450.00 (plus you get a ton of other robot experimenting parts!). Another option for hobbyists are used SICK serial-port lidars; I've picked those up for around $300.00 off ebay. They run on 12-24 volts (great for vehicles and electric wheelchair-based platforms), and use RS-232 or RS-422 for communications (where it becomes a PITA is when they are set to the RS-422 protocol - because then you need a special adaptor - and not all of the adaptors work - to reprogram it - using a piece of software that runs on Windows NT4). They are very robust units, though. Big, and heavy (not for small robots - not at all; these units are about the size of a coffee maker). There are three main types - each with a different color case (yellow, blue, and grey). One of them is an "area coverage" only sensor (and doesn't have a way to output scan data), while the other two are more generalized (at least, this is what I recall - I probably have some details mixed up). These are on the used market because companies are phasing them out, I believe, for the newer ethernet based models.

the 2D LIDAR is of a vacuum cleaning robot, it has a range of 5m, a toy that cannot be compared with a automotive LIDAR that has 150+m range
