Anyone can make custom chips now with Tiny Tapeout and ChipIgnite.
I put several project on one of those shuttles and one of them is a POV controller to display text and graphics in mid air.

Mir war nicht klar, dass man so konkurrenzfähige Preise in Deutschland bekommen kann. Meine PCB's kamen bisher immer aus China - aber das wird sich nun wohl ändern... ;-)

This reminds me of an EFTPOS project I did for a local retail suplier back around 2000. No HDL in that particular one but I had 2 SMD ATMEGAs on one PCB. One for custom keyboard management and LCD drive and one to drive a stepper motor, guilotine and thermal head of a recipt printer. I had to drive a whole line of pixels, over 500 of them. I found a character set I liked on line that wasn't proportionally spaced and downloaded the bitmap(olden times). Then I used visual basic to scan the characters and pixels into a look up table. I had to do vertical and horizontal expansion of the recorded character bits because otherwise the printing was too small. Got it working sweetly, scrolling out printed paper pretty fast. However although my customer paid me, he ran into trouble because of out of memory issues on the PCs. I figured out some time later that his PC custom software writing company likely used a microsoft common library comms driver that was later acknowleged by Microsoft to have a memory leak. However I think the memory leak destroyed his ability to get paid by his customer. Good work on the ASIC FPGA!

Nice. I wonder if you could build something like this into an umbrella and use it as a portable, lightweight screen. Yes, I just watched Kingsmen the other day.

The project is awesome. Question for your next project. What process node are you planning to manufacture your custom RISC-V computer on and what would be the price for 1mm squared dye size? How many transistors can you approximately fit in there? Also, are you using an FPGA to prototype the chip design? If so, what model?

Great work. You might have killed the xtal on the ESP32 when you put it through the ultrasonic cleaner. ASIC design has come a long way from when I started in electronics. Verilog / HDL was quite new when I started, you normally had to get a library set from the ASIC vendor and then build out the required logic. I really wish you all the best

What's cool about knowledge is it accumulates. Keep studying, and trying to make things, and eventually you accumulate a great wealth of knowledge!

@TheDavidsonary 3 ай бұрын

I would propose that -rather than just studying- you just think of something that would be cool to build/code but you have no idea how to do it. Then just don’t stop trying till it is done. That is always a massive XP gain.

I can recommend THT USB-C connectors for personal projects. Easier to solder an debug, I'm using the USB4085-GF-A.

good service from Aisler? It was the worst company I had to deal with. They messed up a simple 4 layer PCB. More than half of boards had USB-C connectors with shorted or unconnected pins. It took them months to send us repaired boards and not all of them were fixed. At this point I stopped asking them to fix all of them because as a prototyping project, it was no longer relevant at this point. I had no problems with Eurocircuit.

When I solder ESP32 by hand, I never put solder onto the thermal pad and never had any problem with it.

@309electronics5 3 ай бұрын

Its often not even needed. I have seen some cheap dev boards which also did not solder the thermal pad. If you dont extremely overclock it it should stay perfectly happy

@AttilaAsztalos 2 ай бұрын

One would think the tiniest drop of mundane CPU thermal paste would have been more than enough to make a positive thermal connection there, without the need to actually solder it in. If you want extra fancy, you could even use thermal GLUE, which does the exact same thing but even glues the thing on, and it sets slowly enough to let you solder it in comfortably...

@Freireg1503 3 ай бұрын

Such a nice project! But if you want to build your own CPU why not start with using any of the softcores frameworks available?

@gsestream 3 ай бұрын

and fpga with reasonable mass production would be much much better, the minor percentage of wafer are usage difference does no matter at all, when the fpga chips can be mass produced without thinking the end usage, the user can used it in whatever way freely. and you can also diy chips on a wafer, which is tons more interesting than just fab ordered chips delivered. current low costs fpga chips run at 400MHz or 800MHz by default. for hobby sake yep of course, but you can do stuff smarter too. any manufacturing should not be for "making living" but for free making of projects, opposite of making a living, ie freedom. then all the considerations of market money law nonsense will not make any factor in the reasonings and efficiency and usefulness. compare the programming/usage experience to arrow MAX1000. have a reel hanging pole like a dress hanger pole. lol. yep curse/blessing of asic is that you dont have to or cannot change the code logic. there needs to be the asic part of the fpga to load up the code. going fabless hmh.

I would love to subscribe to the chips as breakout boards, or see them on commercial products. Such a shame that they are so limited. I totally understand that they are on the side of a wafer that has a limited run, but still would be nice if they could run off a few thousand

What's an open source shared silicon? Is it like RISC-V chips?

@JH-pe3ro 3 ай бұрын

Open source shared silicon means: 1. What is open is a transistor-level description of how to fabricate the chip into a permanent silicon ASIC(vs FPGA designs, which are flashable firmware, or RISC-V, which is an instruction set that a chip can choose to implement) 2. Because chip fabs cost a lot even to do the smallest run, Tiny Tapeout, the project bitluni used, shares hundreds of small designs on one die as an anthology. The board can choose to run any design on the chip by setting a certain pin configuration.
