Bluetooth Speaker Giveaway

Uptated June 10, 2018.

You will have seen my blog entry recently about goodies from Inateck including their The BP1109 Bluetooth speaker which I’m now using a lot… it is lovely. Well, they wanted another bite at the cherry so to be in with a chance to win one of these speakers free-gratis, simply do two things.. find the (very) recent goodies blog entry which now has a link to their Facebook page, FOLLOW their page and leave a comment in the same goodies blog entry (you must be a registered user of this blog to do that) to say you follow their Facebook page and would like one of the Bluetooth speakers free gratis. On 10th of June lunchtime UK time, I will look at the comments, pick one reader at random and send their email address to Inateck who will then get in touch with the winner directly to send off the speaker to them. A lot easier to do than to explain. This is genuine, no catches. You’ll find I’ve put Inateck’s Facebook link in the original blog entry. https://tech.scargill.net/goodies-from-inateck/

Plant watering Fiasco

As more technical people wake up to the folly of trying to use simple resistive DC plant moisture sensors, it seems the Chinese have latched onto the idea of capacitive sensing…

Capacitive sensor

And here it is, the sensor that is all over Ebay right now at am amazingly low £2 inc free shipping, that is until the UK rip-off artists get hold of it and at least double that price, which they’ve already done. If you are happy to sit over your plants waiting for a quiet “beep” – not quite so practical then, not to mention the constant supply of new battery pairs.

And definitely not to mention that the easily corroded batteries and active end are only an inch or two away from the waterproof, non-corrosive sensor end. Perhaps where the designers live the soil doesn’t move and there is no rain or snow.

Big Timer

tmp17DBBig Timer is probably the best timing node for Node-Red, providing a general purpose timer as well as  handling summer/winter correctly as well as (importantly) lighting up time (for which it needs longitude and latitude). After all you probably don’t turn the outside lights on at 6pm!! You turn them on when it gets DARK.

New: “toggle” mode. Now with new seconds timer mode AND updated for the latest Node-Red 0.17.5+ including new help formatting and tips on input and output.

Big Timer Status

I occasionally get comments in the blog about people having problems with BigTimer, virtually all get resolved by users themselves and it is quite some time since BigTimer has actually had any problems, so for clarification, here it is working alongside Blynk, inject nodes and with MQTT. I am currently in the UK and it is currently 11.45am here in Blighty.

This particular timer is set to turn a light on at dusk and off again at midnight, unless manually overridden by an inject node or by Blynk (I’ve created a button on my phone which can turn on the output or restore it to auto).  I hope soon to have multi-state button as this has been introduced in Blynk (but I can’t get it to actually work (at least not using the local Blynk server).

Goodies from Inateck

In today’s postbag came three items from Inateck, namely a lovely small, well packaged Bluetooth plus aux input, a USB powered Bluetooth loudspeaker, completed with leads. The unit also supports a microSD card.

Also in the post from the same company, a tiny Bluetooth receiver/transmitter and a quality dual-phone mains charger (not to be confused with a simple USB hub which cannot provide any additional voltage for high speed charging).

Deceitful Advertising

Sometimes I wonder what has happened to trading standards in the Internet age. Today it is apparently perfectly ok to lie through your teeth when advertising, particularly when you can later hide behind the language barrier.

See particularly bollocks advert here at AliExpress. They don’t do themselves or  us any favours allowing rubbish like this…

  5v 6amp means 30w, not 40w as claimed and how can the output be fixed at 5v when the unit also claims to support Quickcharge 3?  Utter waste of time.

The Script

Regular reader will know about the script that Aidan Ruff and I originally developed to put Node-Red and several other packages onto the Raspberry Pi for our own home control purposes. This has been developed with help from several people and in particular my friend Antonio.

The Script, ESP-GO and Nano Peripheral

WELL – here is the script which is intended to help set up certain Raspbian, Debian or similarly-based SBCs which now includes logging and handling Raspbian Stretch (tested on Raspberry Pi  2 and 3, 3B+). As well as it's original purpose of setting up a Raspberry Pi, the script also runs well with several other boards.  See right hand side of the above image for what the script does, given a basic operating system install. Read on…
