My first board (Arduino Pro Mini Shield for RFM69)

user2684 Contest Winner 21 Jul 2018, 16:22 last edited by

I'm very new to Kicad and PCB design so I'd be very grateful if anybody has any thought, comment, suggestion, etc. to share regarding my first board. I'm sharing the entire kicad project at https://www.openhardware.io/view/605/Arduino-Pro-Mini-Shield-for-RFM69.
Even something such as best practice/naming convention, etc. which may sound trivial for an experienced designer could be helpful for a beginner like me
Thanks!

I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system. So please, can we have a 'how to' step-by-step guide to OTA? Please? S.

I bought the Every because it implied it was backward compatible with the nano. No, it's not, as we found out. Be that as it may, any word on a getting the Every working with mySensors?

I have success! (oops, that's suppose to be Timer1) I only sample for 1/60 of a second. What I did was to back up all the timer registered I used and then resorted them after I was done sampling. (As opposed to initializing the registers in setup and then starting the timer when needed.) Now I have a Nano sampling the data and sending it to a MySensors Gateway on an RPi3B+ which then sends it to an MQTT broker runing on an old laptop. Also running on the laptop is Home Assistant running inside of VirtualBox. If MySensors does use Timer1, it appears that restoring the registers allows it to be shared. //------------------------------------------------------ISR ISR(TIMER1_OVF_vect){ // interrupt service routine for overflow TCNT1 = TimerPreloadValue; // must be first line! starts the timer counting again digitalWrite(TRIGGER_START_SAMPLE_PIN,HIGH); samplesVolts[--sample]=analogRead(VOLTS_IN_PIN); // decrement before capturing samplesCurrent[sample]=analogRead(CURRENT_IN_PIN); digitalWrite(TRIGGER_START_SAMPLE_PIN,LOW); if (!sample){ // count down to zero digitalWrite(TRIGGER_START_SAMPLE_PERIOD_PIN,LOW); // indicate that sampling is complete samplingEnd = micros(); TCCR1B &= 248; // turns off timer } } //------------------------------------------------------sampleOneCycle void sampleOneCycle(){ // back up timer registers uint8_t TCNT1_b = TCNT1; uint8_t TCCR1B_b = TCCR1B; uint8_t TCCR1A_b = TCCR1A; uint8_t TIMSK1_b = TIMSK1; // configure timer which starts the sampling noInterrupts(); // disable all interrupts TCCR1A = 0; TCCR1B = 0; TCNT1 = TimerPreloadValue; // preload timer //TCCR1B |= (1 << CS10)|(1 << CS12); // 1024 prescaler TCCR1B &= 248; // turns off timer? TIMSK1 |= (1 << TOIE1); // enable timer overflow interrupt ISR // demark sampling sample = NUMBER_OF_SAMPLES; // count down to zero digitalWrite(TRIGGER_START_SAMPLE_PERIOD_PIN,HIGH); samplingStart = micros(); TCNT1 = 65535; // first trigger right away! TCCR1B |= 1; // turns on timer interrupts(); // enable all interrupts // wait for sampling to be complete while(digitalRead(TRIGGER_START_SAMPLE_PERIOD_PIN)){}; samplingEnd = micros(); // restore timer registers TCNT1 = TCNT1_b; TCCR1B = TCCR1B_b; TCCR1A = TCCR1A_b; TIMSK1 = TIMSK1_b; }

Just wanted to say thanks for this, it is still relevant and useful six years later !

@wrendral said in "Remote Irrigation with LoRaWAN: LM27313 Challenges and PCB Design": I will go with a Li-Po Battery type: 304048 3.7V 1200mAh Might work, but maybe the internal protection will trigger with the high current peaks. I'd suggest you plan a 0 Ohm, (2512/THT) resistor as R2 and then replace it with a 100Ohm/1Watt if the protection triggers.

There are air quality monitors that can detect VOCs (volatile organic compounds), and some that claim to pick up marijuana smoke specifically. Devices like the Airthings Wave Plus, uHoo Air Sensor, or Plume Labs Flow could help identify changes in air quality. Another option is checking with industrial-grade smoke detection companies that provide sensors for businesses and schools, and some of them may also have solutions suited for home use. If you want more information on vape-related products, including how they work and their components, check out Geek Bar Pulse X Platinum Edition. Understanding vape devices can help recognize patterns of use or detect scents earlier.
