The WORKBENCH part 1


(Deux Vis) #1035

Thanks, makes sense.
That’s why the kind I can usually buy in shops have that round plastic shield.

Now that is a job for my 3D printer to add something like this onto the unsafe ones I ordered…


#1036

but I’m afraid that won’t fit on the adapter…

Alternatively :wink:

to suki liao from the microscope shop… THIS is what we need in parts of Europe :wink: @BoRRoZ, there fixed that for you! :slight_smile:

Other regions need something like this

Or perhaps one with interchangeable ‘blades’ so you can ship just one SKU:-

These are often found on networking & consumer products shipped into Europe…

Laird…are you listening/watching?! :wink:

@BWhitten - FYI also :slight_smile:

trouble
will I ever receive my antenna analyzer bought on eBay ?

how to create a poll on this forum


(Deux Vis) #1040

The one time a seller wiped his account before my item arrived, I never got it.
Got refund by paypal then ; just don’t forget the time limit.

1e conclusion : everything fits like a glove… have to test the temps later


(Mat89) #1042

wow, 120$, that’s cheap! I paid ~151$ or so on ali!
Maybe it was just a fake seller? :frowning:


#1043

when I ordered I did see he was a relative new shop but more then 70 reactions and mostly positive.
And indeed I calculated that he could send the old model… not completely disappear :sunglasses:

Well… I get my money back So that’s not the problem, I shop with confidence on ali / ebay and always use paypal and no complaints.
(maybe it even will arrive ??? :rofl: )

the new RAK TALKY :sunglasses:


#1045

The PCB’s are not mounted to the case which any screws?


#1046

the rpi is mounted on the bottomplate with screws.

more dangerous is the impression given by RAK, that you can mount their ‘magic stick’ antenna with an adapter plug direct on the adapter board.

DON’T try this @ home !! it breaks … :scream:

luckily its the GPS connector (gps module is not mounted so no probs but… be carefull)

x905
didn’t noticed the led’s before… nice touch

cool !

air inlet / outlet for the mcu controlled 'particle chamber.
3oo mA is a lot to open a little valve… hope the little pump is powerfull enough to switch off after a short time.

65535 + 1643 + 1 + 1 = 67180 frames transmitted
67180 x 5 min = 335900 minutes / 60 = 5590 hours / 24 = 233.2 days on a single AA battery … :sunglasses:

Way to go! Well done @BoRRoZ & @rocketscream…now if only we could buy them! :wink:

goodmorning … I start the week with fresh ideas :sunglasses:

(Gry Kyo) #1052

5 minute intervals are very close for a “deployed for life” environmental node? Had your interrupts been hourly or 4 x daily I think the hardware issues with Bosch sensor or physical robustness would have been limiting factors, not the battery life.
, That all said, to get 67,000 transmits from a single AA cell is an achievement, cudos to you and the RocketScream crew!


#1053

it was just for testing… max input voltage is 3v so you could more then double the life when using a lithium 123 battery.
the new model has an even better dc/dc converter that will work with voltages below 1.2 v so extending the node’s life, all is done to see what you can achieve with ‘normal’ batteries.

  • it’s not my achievement… I’m just the tester :sunglasses:
