are you still on holidays ? started missing you
Not anymore but I’m still in ‘holidays mode’ (and the temperatures are similar).
dangerous temperatures to work on electronics… a mistake is easily made, So take it easy
a little bit a ‘special’ day today …
The TPL5111 breakout is best when you have an enable pin you can control, the TPL5110 is best when you are able to ‘break’ the power input line to place the TPL5110 between the power supply and Vin.
I have this idea of a ’ LoRaWAN enhanced’ Piggy Bank so children can see their savings on their iPad/mobile…
so I need a coin mechanism to detect what coin is inserted.
something like …
wow… they are big …
some analog versions
- what if I just weight the moment a coin is inserted ?
every coin has a different weight… and store (and transmit) the total
testing the principle
are these accurate enough ?
I’m moving my electronic (hobby) workshop to another room and I was looking online for material to make my own (bigger) workbench.
then I found this ‘used’ office outlet, just 10 minutes from my home and buying a used desk is almost cheaper then building it.
Anybody who needs (NL) an affordable hobby worktable… look
- so I bought 2 … now I get an 3.20 x 0.80 workbench …
and that is really necessary
’ SPACE … the final frontier ’
Have you completed the SHT31D Rocket Scream low power extra long life V 2.0 LoRaWAN node?
Can you share your experience with the SHT31D Sensor?
this morning the test node died… for real
so yes I finished the rocketscream lowpower node test
result : 290 days on a single AA battery transmitting temp / framecounter / humidity every 5 min.
but that test was done with a BME280 sensor
the node died when the voltage dropped to 1.17 V last night
the V2 version (the one that’s available now, will even last a bit longer)
I meant The WORKBENCH part 1
the new node with better SHT31D Sensor.
i read the BME280 is not so good
so I thought you already have experience with the SHT31D Sensor
ah ok that one … sorry no… not finished yet
the BME280 worked fine indoors, but I think it’s getting very fast to 100% humidity outdoors
