Concerning the previous voice activation devices. i am also working with NXP's SLN-LOCAL2-IOT which can be used locally with no internet required like the bull shit Alexa and others that record and store everything you say. by being locally and voice controlled NXP acquiring DSP Company and other allows you to control things with voice not connected to internet which to me is a must for today's Government/Multinational Corporation spying campaign world wide.
I am looking to integrate this with an open source home automation system for a secure solution to automate your home. the connection between your phone and your home will be encrypted of course. then this will and can be connected to sensors of your Figuera device for monitoring.

Some new information regarding the PWM voice control board I came across. It seems I can not use zero cross Triac for phase control of the circuit. I have to use a random crossing Triac so I changed the id number on the board which has the same pinout as the original which is good. through further testing and completion I will post on this thread.

Concerning my 12/24 volt Duel tracker board. I still haven't sent the board in because of a few changes and attempt to minimize the code needed. looking at the board there are enable pins for each half bridge. since each half work together ie... N/S and E/W there is no need to have four enable pins being coded since one half can not work without the other half. so what that means is the enable pin from N/S are routed together and E/W are routed together simplifying coding to just two enable pins. The PWM will control whether the high or low side is active at any one time. This bridge has overlap protection and programable dead time.
This also frees up two pins on the Teensy to be used for other things possibly.
I have also contacted Skyworks Solutions to see if their chip can be powered by 5 volt and be triggered by the lower voltage 3.3 volt Teensy. the digital input has Logic High Input Threshold at 2 volts but it is better to be safe then sorry burning out the Teensy's I/O. unfortunately they are completely stupid and know nothing about their acquired company Silicon Labs which make the driver chip. so I am waiting for a response from them before I will send in the board because I want this board to be perfect unlike the flood of shit on the market from CHINA.
I have spent a lot of time on this project and want it to surpass EVERYTHING available because it will have my name on it.

Seems Shyworks is a BS company with their tech support almost non existent. I have not had one email in well over a month. I am really fed up with these multinational companies that care only for the big guys. Funny us little guys are the ones changing the world for the best and them the opposite.
I will test them and post the results and probably burn shit up.

SO upon further research i found that all ttl compatible devices can be used with lower capacity 3.3 volt devices. Like for instance my shift registers I use for my Teensy are ttl compatible yet powered with 5 volts and logic high is 2 volts. All ttl devices that have a logic high I/O at 2 volts can be used with a MCU of 3.3 volts.
In my solar tracker I am using a LoRa E220-900T30D for communication that is suggested to use 5 volt power supply. The chip inside the LoRa has I/O's that are 3.3 volts so YES! i can connect to the 3.3 volt Teensy 4.1 I/O's and be just fine as the spec sheet says I/O at 3.3 volts.
SO what does this mean, that all i need for level translation is for my 5 volt sensors which i need 6 of them so for that I will use the 74HCT245 bidirectional level shifter connected on top of the Teensy 4.1 with a daughter breakout board that has the sensor connections and the Ebyte LoRa device.

Trying to secure a few jobs to continue my research on the Figuera device but in the mean time I finished the daughter board for the Duel H Bridge board. The daughter board will house the LoRa and sensor connections but I am revising the sensors. If you look at the daughter board second pic you will notice two spots for a LoRa. one is for the 22D and the other is longer the 30D which is longer wireless range. This is powered through the teensy 5 volt pin supply on the H bridge board.    Regards, Marathonman |

Here is a little extra shit i do. Designed a Teesny 4.1 breakout board that has a RJ45 Ethernet and a USB together. The ribbon cable will connect to the Teensy to this board that is capable of being attached in a box or a panel.   Regards, Marathonman |

I am purchasing a flux core welder in the next few days so I can finish my electric four wheel buggy I am building. The battery is made from 60280 cells at a rate of 48 volts at 57 ah. The buggy will have duel shocks on the hinged rear with two seats for passengers. I also have hydraulic brakes and twist grip throttle. I will post some pics later as I will be rolling on white three spoke 29 inch rims which will look good on a flat black frame.
All in all it has been fun doing this project but the next one I will use aluminum instead of metal tubing.
