Free Chemistry, Heating and LoRa stuff [UK]

shabaz

Hi, I've got some items unrequired, if you're in the UK and wish to have it, please let me know if you want "chemistry" or "LoRa" or "Heating" stuff and I'll post it for free.

All of this stuff is new and unused, and I hate to just throw it away since it's quite useful stuff.

 

Chemistry stuff:

6 x 100ml beakers (glass), a plastic funnel, 4 glass pipettes and some boxes of universal indicator (like Litmus paper).

 

 

LoRa stuff:

Two SX1276MB1MAS (European variant) LoRa transceiver boards, and two SMA antennas that I think are for the 868MHz band (the boards are dual-band, they have 433MHz capability too with the correct antenna). They're for mbed boards, (might fit Arduino but I don't know), but could easily be connected using jumper wires to any microcontroller board or Pi for instance.

 

 

Heating stuff:

Two Quartz Halogen tubes (277mm long, from Ceramicx, 240V, 1kW each, plus holders with aluminium reflectors and a few miscellaneous things like ceramic screw blocks. I got these with the intent of making a reflow oven, but that never happened.

    Hi Dubbie,

     

    Thanks!!

    You're absolutely right, it is really hard finding a home for old tech books and all sorts of electronics : (

  • When I retired I had an office full of electronics 'stuff' gathered over35 years of lecturing. Some of it, being 35 years old wasn't that much use to anyone. But other stuff, such as PIC ICD1's and 2's, hundreds of PIC based boards, MBed based stuff, 8086 emulators, oscilloscopes, electronic compasses and loads of similar stuff just went straight into the bin. I managed to offload some of the WiFi bits and pieces to another lecturer but nobody wanted the rest. The technicians said just chuck in the bin as they no longer carried stores of anything. I managed to fill a whole 6 cubic yard WEEE skip all by myself by the time I had emptied my office. Nobody wanted my technical books either so all 300 - 400 of them went into the bin. There was just nobody who wanted it. Everything is on the internet so books were of no value, the electronics was so cheap that if anyone wanted something they just bought new.

     

    Still, I did walk with a lighter step once it was all gone and my office was empty - that was my work life ended. I have no regrets. Now, if I'm not using anything it goes straight into the bin - why wait 10 years for a clear-out. If someone else can use it why not let them have it. Good on you Shabaz.

    Very cool! Nice to see it functioning like this.

    The two modules running on 2 Arduino MKR boards. One as sender, one as receiver

    Edit: difference between transmitter sitting next to the receiver (left) and both devices two floors apart (basement and upstairs room, right)
