Oscilloscope ASIC Kickstarter instead of Open scope.

I really should not have to explain why you do not develop a semiconductor in 1 thread on a message board but ok. :palm:

To eliminate 70% of the posts repeating "you will never fit the budget" from the nay sayers with 1 zero experience, 2 not the slightest knowledge of what is and is not possible, 3 don´t understand the project. Out of 17 Replies since yesterday only about 3-4 were in any way shape or form productive. You can´t develope a product on an open forum with 1000s of people who are not involved throwing their opinions into the mix. I know I am no expert and I don´t pretend to be but I have done some research and don´t need to reply to 20 people that misunderstood the original intent and have done no research but are making claims as facts.

Also can´t work a project with only one communication thread and maintain any organization.
There will have to be Non disclosures signed etc. for Design Kits so certain things can´t be public.
Sharing confidential info and files.

I think those are enough valid reasons that your question has been answered. This thread can still be used for outsiders to throw their 2 cents in but this is not a place to get work done.

This is not directed at you so don`t feel attacked this is just a general notice to downers.

If you don´t think it is possible keep it to yourself, it is not helpful. If you have a suggestion how to improve it or a valid concern that is great I would love to hear it. If you say I would rather have this feature instead of that feature Super. Just saying it wont work or it is not what anybody wants doesn't help because apparently at least someone wants it since several people have expressed interest including me.

As stated before the economies do work because these companies can even afford to keep the manufacturing quantities even lower by not selling the chips publicly. The most expensive part is the NRE after that they can enjoy huge margins.

A few years ago people would have said you could never afford a 3d printer. they cost 10s of thousands. the Makerbot drove the price down and now they cost a couple $. Same with Arduino, Arm SOCs and everything else. People need to get out of this boxed in mind set that these things can only be done by big companies. Especially on this forum people should understand that.

If you are a manufacturer buying FPGAs and ADCs right now, you can just as well purchase an ASIC to combine those things. With free access to the basic framework for the software your development costs drop even more.

There is a certain counterbalancing factor, which is that not everybody wants to be a manufacturer of glorified reference boards ;)

Chances are that established players would rather collectively boycott you and shut you down with patents. They have their own special snowflake SOCs, IPs and "differentiating" features which they aren't sharing with anyone. But you could target the sort of vendors who make all those PCB modules sold on AliBay, if you get it to the level of "route BNC jack to pin 1 and read capture data over SPI from pin 2, pin 3 is ground and 4 is VCC, please bypass with 100nF".

.......................

If we make a chip for up to 1Ghz and 4-5Gsps using interleaving on 1 channel that would bring the cost of the scopes used by over 50% of the market down to something affordable.

I don't see 7k as affordable. Although it is great to see prices coming down. That just proves the points I have been making though. 1 siglent is a budget brand. 2 they were selling all those upgrades for over 2k before even though you already had the hardware.
3. Why can Feelelec give you a signal generator where the HW + Software costs 1/5th as much as their software upgrade. Why can the DreamLabs sell you a logic analyzer for $80 with the HW and Software and they charge several hundred for just the software upgrade.


The Rigol 4000 or 5000 I forget which one, costs $900 for the base model but over $4000 with all upgrades. That means it contains under $500 worth of parts. Is it really justified to charge almost 1000% for the software that has no repeat cost associated with it?




Magic- I don´t expect the big manufacturers to use the chip they already have their own. You will see a lot more companies like Hantek, MCH etc spring up though. That is who I expect to be interested in this. Maybe Siglent and a few other smaller manufacturers.

That is exactly the direction this should go in. Just like those DDS chips from Analog that allow people to build a signal generator. You brush off those modules, but the difference between a lot of them and a product from Siglent, etc. Is a plastic case and a little more refined software and user interface.

There are also other products that could benefit from easy access to signal capture and processing without the added development associated with an FPGA. Imagine what you could do if you had an STM32 or ESP32 and access to high speed signal capture and processing. You would have to interface with the chip over SPI or even faster interface but also with a DDR or SRAM for the captured signal.

That is like saying that Apple will boycott me if I try to design an OS. There is nothing that Apple needs from me but other companies who sell computers might want a good free OS that gives them the same stuff as the big players.

Also your counterbalancing factor is what all these companies like Hantek etc. are doing.

How many people
1) need >2Gsps
2) would be interested in a hugely risky Kickstarter
3) can't afford one of the many tried and tested off-the-shelf scopes?
