Good analysis. At one point, the fps1000 creator advertised a "hex" model with a much higher datarate - like 720p at 7kfps or something. Maybe this is possible using the flash architecture and parallel fpgas. I haven't been following it, though.

I had ordered a hex but the model was canceled and this one was offered in its place. I believe the HEX may have been based around a different sensor though as the fps1000hd was announced over a year later.

WRT injection molding: you can get aluminium molds for a few hundred parts (protomold is a company doing that).

Is it just me or do those boards look hastily autorouted (at least to some degree)? Lots of weird bends and joins, and would explain why no attempt at length matching or even differential LVDS routing was made.

Thanks for the tear down, I have a FPS1000HD which I waited over 2.5 years to get and it's collecting dust due to the program issues. I have the latest version of the software but it's still buggy and very hard to use. I backed the chronos 1.4 also and can't wait to use the camera for a comparison.

Pretty generous review.

the 18650 holder was a really cool feature actually, i wanna see more larger cameras use that!

I also agree in that the Chronos is the better coice, but it's nice to see more than one successful "High speed camera" kickstarter project. This video also gives good feedback to the FPS1000HD developer(s) on what to sort out in the next camera Rev

If they didn't do equi-distant traces on the flash around the sensor + splitting the output could definitely be causing that odd refresh issue. Probably not actually a "refresh" issue as much as the data being sent in narrow rows that aren't in sync. Also, great tear-down & good on you for giving constructive criticism to the creator(s). :)

You don't have to length match around sensor necesarily, most modern FPGAs provide facilities on the IOB for callibrating out routing delays within reasonable bounds. If you look at highspeed Onsemi sensors, you will see the sensor itself provides training signal pattern during readout inactivity periods exactly for this purpose.

Use High Drain Vape batteries. IMO I like having the 18650 Battery option its better than the cronos.

5 fans would probably be worse, because the warm air couldn't escape. Just stumbled upon this channel, i like it! Well done.

Hey! Never been so early to a video! Good stuff on High speed!

I also noticed the same flange issue as you and told Graham but he had no reply. I measured the flange distance and it was a few mm too large for CS mount. Without a modified adapter I can't get infinity focus on a c mount lens.

correct me if im wrong, but isnt flash memory a bad idea in this application. Since the chips have a very limited amount of rewrites, as well as wright speed beeing slower then DRAM.

@shocksplash6856

I could see what your thinking, but flash is actually pretty hardy. Yes it is fully writing the disk as its recording, but it will take tens of thousands of cycles before it begins to error. And yes the write speed is quite slower than DRAM, which is why the fps1000 is limited to 1000fps. If it wrote to Memory then it would be able to hit 1500.

I think they have or will add some wear balancing to the FPGA config. And Flash is actually not so bad. Much better than a hard drive. If used correctly it can take hundreds of thousands of rewrites - especially if you have another 256GB of spares which can kick in as some regions become unusable. Other SSDs also have spare chips.

The pretty simple architecture is interesting and directly recording to flash sure has some advantages, but i guess that makes software development and adding features/fixing problems really hard later on with that kind of specialised hardware with 3 fpgas. Also the issue of flash aging and reliability/speed could pose a problem compared to using a ram buffer. Are those teary effects only present in the preview and how does the final video look like? That looks actually pretty terrible and might be pretty hard to fix later, if possible at all. One thing i like better on this one compared to your chronos is the battery choice. Single 18650 cells are small and easy to buy or replace. Well, if you have the right cells and not dubious *-fire cells and rely on the user to actually choose the right cells and handle them correctly. But that is just a preference and i mentioned that before ;)

That Fan "Connector" looks great. Oh well. Also i do see both FCC and CE marks yet no real filtering on the DC input and USB connectors? Thats gonna be interesting.

Besides being likely underpowered IIRC most of these "-fire" brands are either factory rejects from reputable manufacturers or rebranded bottom shelf cells.

The sensor is composed of millions of individual sensors in a rectangular array. Together, they act as a diffraction grating and break apart reflected light into its component colors. The same effect is created by looking at light reflected off from the back of a compact disc, for example, in which the micrometer pits are arranged in a tight spiral for the player to read via its laser.

The 512GB flash may be used as raid to increase W/R speed, and also as redundancy.

Harold Edgerton built a camera that had film pass behind a lens like a normal film camera but at crazy high speeds. Instead of having a mechanical shutter expose the film there was a strobe light driven by the camera to flash at hundreds or thousands of times per second, that way the scene is only lit for that very short flash, recording the image and allowing the film to advance in darkness between flashes. It was nuts!

I'm not big on electronics but, the sensor being open to the elements is awful. Even when I change the lens on my DSLR I'm worried about getting dust on the CMOS. I'd feel I wouldn't be able to use the the camera in many conditions that I might like to because if it.

your camera looks a looooot of more polished in comparasion with this FPS1000HD, congrats.

I am no expert in any way, but this thing looks pretty terrible to me... Slotted screws, tape everywhere, bodge resitor, sloppy fan connector, no length matching, tons of wasted space on the PCB... On the other hand really high quality injection molding with brass inserts, which costs a fortune! And not only procuction optimisation lacks behind, but also usability with those unlabled ports, missing hand grip and general architecture, writing directly to flash soldered to the boards seems like a terrible idea. Looks like a very early prototype to me, not like a finished product. Chronos sure isn't perfect in its current state, but it is miles ahead of this as far as design goes...

Electra Flarefire There is nothing wrong with garage made. But when you're trying to market something to the public, of whose money you took to produce it, it should be a bit more polished than this. I love garage made, but the main point of "garage made," among others, is so you don't have to pay for "factory made." You can tell that they went bankrupt by the places where corners were cut. 1: No screen printing/laser engraving. 2: No charger included. 3: No batteries. (Actually a lack of a proper prismatic cell altogether.) 4: A bargain basement lens. (He obviously had plans for a better one, and since he said he would provide a lens, he had to stick a bottom tier lens in the box.) This is what happens when you expect an inventor to design, prototype, build, "mass produce," and market a product. He didn't know how to budget the money. and is why he ran out of money and cut corners in some places, and went overboard in others. I'm not blaming him. It's more than I've ever done. i was just pointing that out. It doesn't look like a finished product. (Which is what it's supposed to be.... a 100% completed, consumer grade, product.)

To their credit, the rudefully-coined (yeah, Dave's gotta work on his couth,) "bodge" resistor should be forgiven on a prototype -- especially because those PCBs likely cost more to make/test than the chipset. Otherwise, the project reflects upon its worth by the choice to employ slot screws... I concur as stated below: who t.h. uses such fasteners?! Mock!

How many times can one write to these flashes, before having to throw away the camera? I would've used RAM. Poor design all around. Length matching, at these speeds, is a must. Not impressed. Excellent tear-down.
