this is a topic for the DIY TTN’ers, the builders, the makers, the tinkerers  
here you can show and ask, chat and have some fun.

So, anything related to (electronical / mechanical) DIY that don’t  
fit in other topics ( but is in some way related to building and/or TTN )

E-pub?

…so we have to drink flux if we want the conversation to flow?

Good work @BoRRoZ

thanks 😊

one of the projects I hope to finish (before August) is this :  
a wireless chargeable wifi google assistant ‘pad’ for my old (82) mother, She can’t use a normal computer(mouse/vinger) because she 'trembles with her hands, but she’s very bright.

she can take this with her and just ask what she wants and it answers in DUTCH (works)  
I will make it as simple as possible to use and charge.

I realised yesterday that I need some **protection** for these speakers or you push your thumb through them 😩

- found them

@Jeff-UK

now you bought a fit tracker and combine that with your area mapping when walking, I suggest you join LMA too.  
**LoRaWAN Mappers Anonymus** (LMA) use gear like this to walk around and map the area with devices hidden under there coats.

…just back from mapping around Burnham Beeches nature reserve - just set up a pop-up GW (SMTC LoRa IoT Starter Kit! so didnt have to worry about internet connectivity/backhaul) then popped a LoRaMOTE/GPS tracker in my hat! (Cold out)…Looked a bit silly (too embarrassing to post picture!) but effective test of node at ~1.8m elevation 🙂

Burying under layers of clothing can diminish sign strength esp as some synthetic fibres more RF opaque than expected! (Important to note & test for if considering sensors for lone workers sensors & alarms or 1st responders… 😉 )

As the first test was quite quite successful and I had all the parts anyway I assembled the left over MiniLora PCBs!

Well I don’t think its old thinking but more of the modern thinking. Back in the days, CPU power was expensive so algorithms and code was optimized for speed or size (depending what was the bottle neck). Now a days, I see developers asking Sys to crank up there VPS 's because the platform is to slow. 😉

Next time you need to leave the K off the end. It is a System on a Chip (SOC) you wanted, not a SOCK 🙂

Alternatively you ordered 4off of heat-socks ( 2 x matched pairs?!) rather than heat-sinks for that 1Kw inverter! 😉
