pypilot store open again

[seandepagnier]

I finally opened my store again:
https://pypilot.org/opencart/

I have minimal products available, but with a hat and motor controller it's possible to make a working pypilot system.

I intend to have high power controllers (30 amps) again soon, as well as many products in the future though it will take more time.

Right now I am working on:
1)  fully waterproof pypilot computer with 3.5 inch screen.  much larger display higher resolution and 4 grey rendering
2)  multi function displays fully waterproof monochrome and color daylight visible can plot most instruments including history plots and gauges.
3)  fully wireless 3d printed wind instruments running on tiny solar cell to mount anywhere with 10hz output rate and integrated IMU to compensate boat motion.
4) depth transducer driver (work with existing depth transducers or using 200khz transducers available for about $50) creates wireless fish finder with full control of driver an receiver.

All of these have working prototypes so far.

Then further on I still intend to make the sonar measure water speed then also do a phased array sonar for true 3d mapping and several other ideas.

The prices are unfortunately higher now because of recent tariffs imposed in the USA that actually increased cost to produce by 45% which is a huge change from 1 year before.

Hi, wireless wind instrument is interesting, you take into account the location for the solar radiation? (here for example https://maps.app.goo.gl/bKhQoiTYShpMSbok6)

According to my basic calculations, average power of 2mW using 100mW solar panel should work all the time in most locations most of the time.

I intend to reduce the output rate of 10hz to 5, 2 then 1hz when power is limited which gets the draw < 1mW, but even still there are locations in higher latitudes and/or winter with enough overcast it will not work. It becomes impossible in polar regions in the winter. I am using LTO cells which can handle extreme temperatures and also very long life.

Because sailing in these places in the winter is likely limited, I did not worry about it too much, but I have a powered version of the wind sensor as well.

Sean,

Great to see your store is open again. I once ordered one of your hats but later on I made my own. I sold the hat and I was amazed how much people wanted to buy it. I hate to admit it, but the the bidding war that started resulted in a higher price than I paid for it.

I am really looking forward to your wind instrument and depth transducer, and speed sonar. Those are 3 things that I have on my list as well to develop in this year. Will the code be Open source? If yes, do you have any plans when you will you publish the work? I assume it is C++? Wireless protocol will be BLE, radio or ESPNow?

I have espnow wind sensors already but the problem is the power is not low enough to run on a tiny solar cell, so this version requires power wires (just 2 wires) and the data is wireless.

The fully wireless version must use a 900mhz (or can do also 868) with a bit of complication FSK type encoding.

As for the depth, I continue to develop and probably cant do actual testing for a few months but so far I have made incredible progress on the signal processing. I hope to eventually make phased arrays for 3d mapping.
