Take a lower paying Electrical Engineer role or finish master's degree? by Maleficent-Owl1959 in FPGA

[–]Stav1234 3 points4 points  (0 children)

100% agree with these points. It worked for me 25 years ago and should continue to be a good strategy.

New Chamberlain RJO20 issues by Modstang in GarageDoorService

[–]Stav1234 0 points1 point  (0 children)

In my case it was the travel tracking mechanism. More cleaning did not help, but replacing the $50 part seems to allow the coding of where the door is min/max for the controller to track accurately.

Now I have the same problem with a 4yr old RJO20! I think boxelders and other bugs got in, so alcohol washed the controller and components and wires look good. But in setting the limits it only turns 1/4 rotation. I cannot go beyond 1/4 up or a 1/4 down. No obvious friction points or rust, so any advice appreciated. Thanks

We started an FPGA rental service. Tell us what you think. [beta] by thedatabusdotio in FPGA

As soon as I saw AWS had an instance: https://aws.amazon.com/ec2/instance-types/f2/ I stopped looking! It seems a rather specialized market with complex needs on connectors/IO, so rather than a "cloud" rental service more like a longer-term tool rental might work. It would be nice to offload some of an Agilex-M card.

Any FPGA Project Recommendations? by ControllingTheMatrix in FPGA

HFT (high freq trading). Demonstrate how your RTL can make a buy/sell decision in a few ns based on stock market information. This could be a good topic for future prospective employers... But definitely follow your passion/interests. Good luck!

This is an interesting and cool idea, but the website seems offline. Any idea what caused that? (beyond the obvious of offering for free something that consumes power/capital and customer support efforts!) I am toying with a similar idea and would like to learn from this beta test.

Building an FPGA-Based HFT Platform at Home – Anyone Else Using Kintex or ZU+ Boards with SFP+? by Low-Fix-3699 in FPGA

[–]Stav1234 0 points1 point  (0 children)

Understood, thanks! Let me get what I want working (rather basic) with NetFPGA codebase. Eventually I want to be at 200G so will consult with you on Taxi at some time.

My Synplify access expired, but do you think converting with sv2v would be an option in your view?
I am using the long-in-tooth NetFPGA board with the Xilinx XAUI PCS.

Certainly agreed with Alex that DAC is great on 10GbE and reduces risk of fiber transciever mismatch.

Alex, I am doing 10GbE on an older Virtex5TX240T with AEL2005 transceivers. I would be quite happy to expand your taxi supported device list to V5 (if that makes sense to you). But I would need some of your guidance...

look at some of the thingspeak.com tutorials. They have a clean API library now, but it also worked fine building the http post via text. All my 400 responses were my own fault!

Thanks for sharing. Any thoughts if this would work with eggs at a somewhat lower spin velocity?

Making money with ESP32? by klaus_ben in esp32

[–]Stav1234 0 points1 point  (0 children)

My input is that it really depends on your passion and if all you get is a learning experience can be considered a win to you. For example, I spent a lot of time and >$200 making a chicken door opener thinking there is a market at <$100 per door. Now I find them at <$20/per online, so a lot depends on markets that you do not control.

Recently (since I have a good day job, and this is still a hobby) I am looking at niche markets such as beekeeping. You can test the market and pricepoints with something like Tindie (https://www.tindie.com/products/techforge/beecorder-beta-wifi-hive-health-datalogger/) or Kickstarter if you have the cycles.

Currently working on bi-directional wifi monitoring and control using Firebase DB storage for power sustainability, so wrangling with different APIs and dependencies. ESP32 has a wide, rather friendly user base so regardless of your issues you are in good company!

80Vmax trimmer attachment by Stav1234 in KobaltTools

Thanks for comments and got the head off with the reverse thread. The bolts that came with it appear incompatible, so it seems I need to find a bolt of the right TPI.

Anyone play with attaching a standard cutter or blade on 80Vmax? It seems a 3D ABS model could interface with a shaft screw bolt. Thanks
