I bow to your cartography. Such a formal resting place's rules certainly should be investigated. See => https://www.napier.govt.nz/services/napier-cemeteries/western-hills-cemetery/ (Some decades back we lost a daughter & found our desired headstone did not fit the cemetery's criteria ...)...

Greetings -that lat./long. is ~Taupo,half way up NZ's North Island. Very sorry to hear of your loss but (in light of my experiences) if the memorial is in a public cemetery best first consult with the authorities regarding anything of this nature! Some have strict rules about headstones...

Coals to Newcastle (!) as when an early 1960s teen I used to import (by seamail...) UK sourced e-items. I'll check p&p & let you know. Stan. in NZ

Yes -I indeed ran with the "Snap" concept & (as well as IR) also looked at rustling up modules for inbuilt DS18B20 temperature reading or 2 way 433 MHz wireless data. Elenco & I were in touch at one stage too. This was ~2007 & pre the likes of BT & smartphones etc. Where do you live ? I could...

Gasp -yesteryear! About 16 years ago (& pre Elenco's approach) I rustled up a 08M based "Snapped PICAXE" article & Instructable to support educational STEM work. The gutted Snap sound module/08M based design pleasingly proved versatile enough to suit both micro motivated youngsters & curious...

Indeed - & NOT off topic but appropiate "state of the art" technology - Android smart phones make for great e-engines ! Their global abundance & familiarity eases operating ergonomics of course too. Aside from BT & WiFi serial display (suiting modern micros which offer wireless ) direct...

FYI: Publicity has -sigh- again arisen here in NZ when car remotes refused to operate in a shopping mall carpark. Management declared it an "electrical incident", but it's probably 433MHz band interference...

Dauntingly slow times indeed... I wonder how these compare with the original Ciseco wireless modules from a decade back? Anyone ( Hippy ? ) ?

Magnificent, but I must have had a sheltered life as the show is unknown to me. Mmm-30 gives 4 spare after A-Z so scope for more => 1, 2, 3, &, @, $, ? etc

Sorry to hear of the "abandonment" after such sterling strenuous slaving. Fingers crossed for BLE & HM-19 !

Those values look very satisfactory & should be readily handled (outdoors) by a small PV panel. Looking forward to seeing your code & circuitry. Take a break for the festive season ! Stan. in summery NZ

I support simplicity & for the likes of "a weather station on the barn roof " the increased transfer duration should not be too concerning. What typical current drains (both now & originally) are you seeing ? Stan.

Although penned pre the recent MMBASIC persuasion the latest (Dec.2021) "Silicon Chip" mag. has a great RPi pico article,including mention of Pimoroni's stamp sized Tiny 2040 => https://shop.pimoroni.com/products/tiny-2040?variant=39560012234835

Assume you mean this? The 1,2,3 simply relate to ID of genuine HC-12. Although I was an early HC-12 user magnificent LoRa rather took my fancy from about 2015 & I've not kept up with the the fake saga. However I recall new "fakes" had crystals off spec. so that (on the 433MHz ISM band) a...

More good news ! Perhaps an issue is that the HC12 Tx rating of 100mW is too powerful for the 433 MHz ISM band. However it "can" be decreased & even readily set to other UHF frequencies that may be legal in particular countries. Fellow Kiwi Rob Rozee even wrote a configuring GUI =>...

Good work indeed Goeytex! Mmm -I'm now pondering any likely current drain the 14M2 and transistor intermediate circuitry may add. Quite aside from classroom work (which was my first thought of course) I've experiences of PICAXE circuitry in monitoring locations only drawing microamp level...

Goeytex -see my message to you. Stan.

Well said Wapo54001 ! Refer PICAXE background => https://www.allaboutcircuits.com/technical-articles/intro-to-picaxe/ In ~2002 I recall a tech. student saying he'd done more in 30 minutes with a PICAXE than he'd managed in 30 days with a raw PIC ! BUT that was e-yesteryear, pre dating...

Yes indeed & the abundance of such educational devices rather prompted my initial posting. Aside from "CABLES -we don't want no stinking cables!" (to paraphrase "Blazing Saddles") such e-devices are ideal for enthusing modern youngsters! Ozobots (first released in 2014) are now on a 2nd...
