  • Odrvm 4K Action Camera by Jason: I was just thinking that if you could somehow hack them to do a standard video stream (e.g. MJPEG or something) they'd make for an awesome security camera for around the house. They're small, weatherproof, have an onboard battery, wifi, good picture etc. Reading about them more though it looks like you need a proprietary app to access the camera, so it'd probably require some non-trivial hacking to do sadly. It'd be awesome to have a simple and cheap camera like this with hackable firmware. Robotics and computer vision people would probably be pretty keen on it too. Dec 10, 16:18
  • Peter Scargill Odrvm 4K Action Camera by Peter Scargill: Actually Bob, most likely I will as I get used to the features. The problem I had yesterday was the simple fact that it was mind-numbingly cold. I'm replacing the video with some minor changes including better sound - but I'll leave this in place due to the RIDICULOUS policy of YouTube where you can't replace a video but have to delete it along with the comments etc... but yes, more when the chill goes away. Dec 10, 12:02
  • Odrvm 4K Action Camera by Bob: The camera looks good, your walk about brought back fond memories of a very pleasant night at Bellingham when I walked the Pennine way, a good few years ago. I'll be very interested to see any further stuff you do with that camera. Dec 10, 11:17
  • Peter Scargill Odrvm 4K Action Camera by Peter Scargill: Ok, so as a webcam it LOOKS great but there's no audio out for some reason - so that needs external audio - but streaming - I imagine you'd have to add some software for streaming... my other webcams don't do streaming.... oh, try out the free YAWCAM. Dec 10, 10:45
  • Peter Scargill SI5351 Clock Generator by Peter Scargill: Thanks for that. Dec 10, 10:20

  • Peter Scargill Odrvm 4K Action Camera by Peter Scargill: I actually figured that out by the time I did the video... and yes it was set to ON by default which seems odd.. anyway, now the back screen times out to save power and that's fine - the top button brings it back. Dec 10, 10:14
  • DrFragle and MrShark Odrvm 4K Action Camera by DrFragle and MrShark: take a look at settings, usually there's an option to divide videos in short pieces, usually of about 3 minutes... can't remember now how it's called in mine, i've seen in many different models, and it's always set to ON...

  • Steve Menheere Enter the SHT30 by Steve Menheere: I have one of these shields on a Wemos D1, but since I updated the ROM to 2.3.15 it goes into a reboot loop unless I turn off the sensor using {temperature_port:0}. Worked fine on 2.3.13, but unfortunately I no longer have a copy of that one. Dec 10, 02:55
  • Odrvm 4K Action Camera by Jason: Your link is broken Peter, I think you accidentally made it a relative link. Looks like a pretty nice camera for £80. I wonder, what can you do over Wifi? Can you stream video? Seems like it'd make a pretty cool little security camera if you can. Dec 10, 02:40
  • Vincent Regaud Boxes Galore by Vincent Regaud: Hello, My first comment... I have used these very boxes that Pete is showing. I ordered 10 a while ago, so I guess they'll be back in stock. I use them with MySensors nodes for humidity and temperature with NRF radios and arduino pro mini. These run on batteries and according to the rate at which the batteries are going (Normal ASDA branded alkalines,) I should have 2 to 3 years before they run out. They sent to an MQTT master node. This then gets "translated" into "normal" MQTT topics and they get dealt with Node-Red and Openhab. I use them to drive individual radiator valves and the boiler so that I can control the heating in the house room by room. PS. I haven't put the blue and red LEDs in it though (too much power!) but I love the idea and I'll implement it on the mains powered ESP that is controlling the boiler. Can't wait to see what it look like! Dec 9, 21:04
  • Peter Scargill IoD-09 Display from 4D Systems by Peter Scargill: Ok you have my interest - you refer to an ESP8266-01 - but you have I2c - and USB - is this a different board to what I think of as an ESP-01 ? Link? Dec 9, 19:23
  • Peter Scargill IoD-09 Display from 4D Systems by Peter Scargill: THAT's neat. Well, someone has to do something about that postage price.... the actual price of the display, it has some things going for it - the extra pixels, full colour, nice bezel and getting the whole thing into a small space. Looks like you've done a good job there. Dec 9, 18:50
  • Peter Scargill ESP8266 Home Control Update by Peter Scargill: I've never tried WPS - and I can't use 2.1.0 right now as it tips me over the edge for program RAM... I'm using 2.0.0 Dec 9, 18:48
  • Peter Scargill Big Nextion by Peter Scargill: I think cost is a relative thing - if you're playing about as I often do then cost is paramount, on the other hand if someone gives you a paying job, it is possible that time is more important than the cost of such a display. They do make life easy in some respects compared to doing it yourself. I do wish they'd put a little more effort into the editor however. Dec 9, 18:47
  • Ian Sexton IoD-09 Display from 4D Systems by Ian Sexton: Hi Pete, Lovely display, nasty price 🙁 I made a very small SSD1306 device a while back for a demo: http://www.myiot.co.uk/openday2 You can't tell from the photos but I2C is exposed too on a 4 pin female header so it can carry (eg) a BME280 etc Dec 9, 18:34
  • ESP8266 Home Control Update by David Albert: Hi Pete, First, thank you for all the great info! I have been using ESP8266 for some time and use WPS to establish connectivity. It works great with 802.11b/g/n routers, but generally fails with 802.11ac routers. I'm using SDK 2.1.0. Have you had any luck using WPS with 802.11ac? You can see more info about the problem here: http://bbs.espressif.com/viewtopic.php?t=1695 Dec 9, 18:32
  • Perry Bebbington Big Nextion by Perry Bebbington: I've got one of the 7" capacitive units as the control interface for my central heating controller running on a PIC18F26K22. I agree the NEXTION is too expensive but it's dead easy to drive once you get the hang of its quirks. Thanks to Pete for explaining how to use the cropped images to best effect. Dec 9, 18:26
  • SI5351 Clock Generator by daturach: Hi Pete Thanks for sharing this excellent blog. I guess you need a SMA male connector like an adapter SMA male to BNC female if you already have such cables at home. I personally prefer cables with the BNC serie. They are easy to work with. Anyway something like this? https://www.banggood.com/4pcs-BNC-Male-Plug-To-SMA-Female-Jack-Straight-RF-Connector-Adapter-p-1050143.html?rmmds=buy&cur_warehouse=UK One more thing: kilo should be abbreviated with "k" lowercase and hertz with "H" uppercase like 8 kHz or 25 MHz 🙂 Dec 9, 17:07
  • VL53LOX Distance Measurement by Bob Green: I have seen the blog Antonio referred to before and the consensus from the comments was that trying to detect a clear liquid reliably was difficult. Hence my thought to try and achieve an easily detected floating target. The application I was thinking about was to turn on a pump when a the level in a tank reached a certain level and then to turn it off when the water level dropped to a lower level. I was looking at a difference in levels of up to a 1000 mm. Dec 9, 16:00

  • Peter Scargill Node-Red and Alexa with Big Timer by Peter Scargill: Hi Andy It isn't what Alexa understands, it is what the emulations understand - so the standard alexa node emulates something that does not understand a lot - basically on/off/up/down and setting a value. Pretty awful really. You can write your own skill to even pull in the words Alexa thinks it has heard but for reasons beyond me, Amazon make that as difficult as possible so most of the emulations like the Node-Red Alexa mode and others take the relatively easy route which does not let you do this. I'm waiting for a node that will handle more including colours - but I could be waiting some time. Dec 9, 13:19
  • Peter Scargill VL53LOX Distance Measurement by Peter Scargill: Yes, I have an oil tank with a tube on the side - you're supposed to be able to tell the fuel level by looking at the pipe. Clearly designed by someone who's never been near an oil tank, once it gets a bit dirty - it is VERY hard to see the fuel line. I was thinking of putting some kind of tiny fluorescent fishing float in there - but you have me thinking now - I wonder if a simple float of any type was to be used and the sensor fitted at the top of the tube - you should be able to get the distance... and if that is the case then calculating the actual fuel in a round tank should be fairly easy. Dec 9, 13:15
  • Andy Shrimpton Node-Red and Alexa with Big Timer by Andy Shrimpton: var msg1 = {payload:"hallway light to 100%" }; var msg2 = {payload:"hallway light off"}; var msg3 = {payload:"hallway light on"}; var msg4 = {payload:"hallway light auto"}; return [[[{paylaod:"auto"}], "OFF"],"ON"]; Hi Peter does Alexa understand "AUTO" i cant find a way to get your BT set back to auto. works for on and off great. Thanks Andy Dec 9, 12:45
  • VL53LOX Distance Measurement by Bob: Regarding sensing clear water I thought about putting a ping pong ball into a tube, say a length of 40mm plastic waste pipe and immersing the tube into the tank. The ping pong ball would float with the liquid level and hopefully the distance sensor would 'see' the ball moving up and down indicating the liquid level. I have got one of these sensors but not tried it yet. I don't know how much spread the beam from the sensor has but Pete's experiments seem to suggest a larger target is required at longer distances. The tube might help to stabilise humidity and temperature. Dec 9, 11:43
  • Peter Scargill VL53LOX Distance Measurement by Peter Scargill: That looks very useful. Thanks for that. Dec 9, 05:47
  • Peter Scargill ADS1115 I2C A/D Convertor by Peter Scargill: In the main home control blog you will find the Bucket repository for my ESP8266 code. Dec 9, 05:01
  • Variable Persistence in Node-Red by Jean-Pierre Lavoie: Another quick question if you don't mind after studying your code today. Where and when do you update your counter? In an external function from this one? Because in your code when the counter is 0, you don't reset it anywhere I see... You have it set at 0 (why?) in your example, but you would need to initialize it at let's say 8 to start with in that external function. So you drop the counter by 1 until it reaches 0 I guess so that you would write to the card every 8 x 5 seconds for your inject node timer = 40 seconds? I'm sure your code works, I'm just not understanding something about the counter management. Thanks again your Node-Red stuff is awesome. Dec 9, 04:27
  • VL53LOX Distance Measurement by Larry Bank: forgot to add the link: https://github.com/bitbank2/VL53L0X Dec 9, 01:21
  • VL53LOX Distance Measurement by Larry Bank: I made a C library that's easy to use and allows putting the device in "long range" mode. I found that the measurements are accurate from 35 to 800mm in short range and 35 to 1200mm in long range mode. The library (with license agreement) from STMicro didn't appeal to me, so I decided to simplify it. I really dislike (aka HATE) when hardware companies try to be clever and hide their I2C devices behind long lists of magic numbers (registers/data) to use their hardware. Dec 9, 01:21
  • Garry Hayne INA219/ESP8266 and Node Red by Garry Hayne: Which board should I choose in the Arduino IDE? Dec 8, 22:46
  • Alan McCormick ADS1115 I2C A/D Convertor by Alan McCormick: Hi Peter, is your i2c function public? I'm trying to use this with an ESP32 but having stability problems that I think are related to the Adafruit library - I'm only wanting to pull off the A0 (single ended) value. Dec 8, 21:28
  • Alan McCormick ESP8266 and ATMEGA2560 Mega Board by Alan McCormick: I've used this board for a few months now, with a good antenna it's been rock solid (better than my breadboard attempt at joining the two anyway!) I found the attached image helpful in setting it up and switching between the two devices. Not bad for 10 quid. Dec 8, 21:22
  • Mathias Jensen Big Timer by Mathias Jensen: Great solution! I wonder though, if anyone else but me think it would be great with two sets of timers i one node, so you don't have to add a second node? What do you think, Pete? Dec 8, 21:02
  • DrFragle and MrShark More Node-Red Dashboard Success by DrFragle and MrShark: they're designed to be downloaded quickly and not weight so much, are available on fast CDNs and as such maybe you have them already in your browser cache, and are used to customize little widgets with a visive communication of what's underneath, usually, not to be colorful 🙂 Dec 8, 19:28

  • Variable Persistence in Node-Red by Jean-Pierre Lavoie: Great, thanks for the tip! Dec 8, 15:59
  • Peter Scargill Variable Persistence in Node-Red by Peter Scargill: Executing a function once only at the start of Node-Red.... put it in the left-most tab - at the top.... and use an inject node set to run once only at startup. Dec 8, 15:04
  • Peter Scargill SI5351 Clock Generator by Peter Scargill: Mine are too small, I need as you say a 45 degree tip. Dec 8, 15:03
  • Peter Scargill SI5351 Clock Generator by Peter Scargill: Fixed, thank you. Dec 8, 15:02
  • Variable Persistence in Node-Red by Jean-Pierre Lavoie: Great strategy for persistent variables. Do you have a simple way to execute a function only at the start of Node-Red? In a power-up situation, after Node-Red starts I would need to execute that function only once, for example turn a light ON to make sure it is still ON like before the power-up? Your persistent variable let me know the light was ON, I then need to act only once after start-up to use the variable and turn ON the light. Dec 8, 14:50

  • DrFragle and MrShark Boxes Galore by DrFragle and MrShark: tried that but the signal the wifi repeater receives and amplify, is already too low to give enough speed... no problems for esp8266 as they have to send/receive small data, but a problem for streaming... a collegue ended up with wifi powerlines: https://www.amazon.co.uk/Powerline-Configuration-UK-TL-WPA4220KIT-V1-20/dp/B01LXOZ4EN/ Dec 8, 10:30
  • Peter Scargill Boxes Galore by Peter Scargill: In the UK, cable - in Spain - one is hooked up to the Internet - and it's output goes to through-the-mains devices. The other access points pick that signal up. Not ideal but beats digging holes in a cave wall. Dec 8, 09:54

  • Peter Scargill Boxes Galore by Peter Scargill: Well, I can only relate what works for me - and yes, some places in the house are difficult to run wires but usually I can at least manage the power lead from a plug-in the wall to a wall unit - which then usually contains an ESP8266 and is therefore wireless apart from power. Dec 8, 09:37
  • DrFragle and MrShark Boxes Galore by DrFragle and MrShark: ? he shows how he reached the actual setup... starting with mains in every wall socket and ending with just an ethernet cable that drives POE and brings the switches to a central unit, where all the logic resides... or better, where the logic is passed to nodered or other sort of home automation systems... he can go from a single switch wall mount to 4 ones just by changing the front panel, no recabling needed... and you need low voltage there, not mains as in quite every wall mount plate we have... but, as in a previous video he said that a manual override is always good (if the central management goes nuts, you can't even turn on a ceiling light...), i asked him how to deal with this and his actual setup, and he was a bit vague... Dec 8, 09:19
  • Patrick Chivell Boxes Galore by Patrick Chivell: Its easy to say"just use wries" when you own your own home, and you have stud walls, and both under floor and ceiling access, and its economically viable to do so. I must admit that I'm lucky enough to have all of these luxuries, but I also understand that not everyone does. What Jonathan has done is relatively easy in Aus, as we dont have the contraints of stone walls and solid plaster renedering etc etc, but it doesnt easily translate to other countries. Its a no brainer to run wires if its possible, for power at least, but I'm not sure about running discrete circuits for every switch, this just limits future scalability. Dec 8, 09:00
  • Boxes Galore by Ed: Nice videos. Jonathan however was reconstructing his house and thus was able to run cables anywhere and everywhere he wanted. Yet I did get some ideas off of him like the wall mounted led switches Dec 8, 05:42

  • FriendlyArm NanoPi A64 by GuidoL: Because I didnt read here about a Non-FriendlyARM alternative OS-version for the NanoPi A64 - I would leave a comment here 🙂 My NanoPi A64 is running better with the following OS: https://github.com/avafinger/nanopi-a64-firmware This is not only a Firmware - is a complete Ubuntu 16.04 xenial with LXDE-Desktop and kernel 3.10.105 My NanoPi A64 also doesnt get hot - so I didnt use a fan. The only thing with that is that creating the bootable MicroSD-Card is a little bit dificult, but the instructions in the bottom of the page are quite well 🙂 You need a Linux-System for creating the Boot-Card - so I did use my second NanoPi = the NEO2 with a single-slot MicroSD-Card Reader/Writer. The NanoPi A64 seems to a good board, but with bad support 🙁 Dec 7, 20:45

I do hope someone comes up with better solutions - I plan to use one of these displays, being full colour and with a nice bezel, in my upcoming I2c clock generator project (8Khz to 160Mhz) it will look GREAT and it would be nice if others can benefit.

  • DrFragle and MrShark Sonoff to Mains Block by DrFragle and MrShark: i don't think so... 1) you can put a plug in the wrong socket and who knows what could happen... 2) you can just buy a sonoff s20 and no (shitty) hacking needed... https://www.itead.cc/smart-socket.html Dec 7, 09:03
  • Darren W Sonoff to Mains Block by Darren W: In theory, yes, but it if it's a fan heater (an inductive load) rather than an oil filled radiator (non inductive load), I'd want to allow a bit extra safety headroom in the relay capacity. Luckily, Sonoff do make a higher capacity unit - the Sonoff POW and the Sonoff TH16 - these are allegedly rated at 16A. I run an Ariston under-sink water heater (2kw) off a 16A Sonoff unit and it doesn't break into a sweat at all although it rarely runs for more than 15 minutes at a time before the water gets hot and it stops consuming power. I use the 16A Sonoff POW running the Sonoff-Tasmota firmware which reports back voltage/current usage and that's a nice additional feature rather than just power on / power off. Dec 7, 08:33
  • Poor Man’s Signal Generator by Bob Green: Hi Dave, That Siglent model SDG1025 is £290 in the UK currently and the Siglent SDG1062X is £380. I must admit to being tempted by the latter, but I am assessing how much I would use it. As you will be aware its features include a frequency counter too. I'll await developments from Peter.

  • Peter Scargill VL53LOX Distance Measurement by Peter Scargill: If speed does not matter... var smoothing=10; average=(average×(smoothing-1)+value)/smoothing; Or similar. Change smoothing to suit, an sure average is big enough to handle that calc. Dec 6, 23:11
  • VL53LOX Distance Measurement by Alan Cowan: Hi, I am using one to measure the amount of oil left in the heating supply tank. I haven't tried it with water but will experiment and report back. I have found that it throws odd measurements sometimes - perhaps temperature dependent although the initialisation routine seems to trigger the calibrate function which should take care of that. I just apply some "eyeball averaging". Alan Dec 6, 22:32
  • Peter Scargill FeelTech FY6600 Waveform Generator by Peter Scargill: Thankfully things do change in time.... I'm busy putting a 3D printer together that videos on the web said needed a 3d printed bracket to make sturdy. By the time I got mine and extra metal bracket was supplied. Sadly they forgot the bolts to go with it! Dec 6, 21:52
  • FeelTech FY6600 Waveform Generator by Bob: Hi Peter, Great News that you had no issues with AC to ground, it was a hell of a long thread on that particular topic. A guy from Feeltech was on it at one point so its possible the issue was rectified on the latest versions like yours. It wasn't Dave himself who made the comments rather it was forum members.

  • Sonoff to Mains Block by oli: Does anyone know if you could run a Dyson heater off one of these? 2000 Watt heater.... 8 amps right? is that how you work it out? 2000/240? Dec 6, 21:04
  • Sonoff to Mains Block by oli: This is quite a good idea. https://www.instructables.com/id/Safer-UK-Sonoff-Wireless-Switch-Home-Automation/ Dec 6, 20:55
  • Peter Scargill FeelTech FY6600 Waveform Generator by Peter Scargill: I will check right now... Ok, well the AC voltage between my BNC connectors and ground is precisely Zero. Still - worth checking. The amount of kit that Dave at EV blog has hooked up - it could be anything... Pete. Dec 6, 17:45
  • FeelTech FY6600 Waveform Generator by Bob Green: Pete, That's an interesting AWG so I had a poke around the web and found this on the EV blog "My FY6600 BNC-ground to Earth-ground Voltage is 94 Volt. Zing zing zing, not happy about it. Will have a look for a cheap 30VA isolation transformer." posted in August this year, it seems there are concerns about the internal PSU. Have you had any indication of undue AC voltage on the BNC connectors ? Dec 6, 17:40
  • Peter Scargill IoD-09 Display from 4D Systems by Peter Scargill: I have written to them - certainly I would not pay even remotely that for postage. And if it went via rogues DHL they'd add the postage charge before calculating additional charges. My new year's resolution will be never to accept anything from them again. Dec 6, 17:15
  • Peter Scargill IoD-09 Display from 4D Systems by Peter Scargill: You'll have to look that up. Dec 6, 17:13
  • Peter Scargill DPS5020 and DPS3003 PSUs by Peter Scargill: Doesn't tell me much either. But looking at the Bluetooth unit, assuming you are looking top down and the connector is at the bottom, it says grtv which I assume to mean ground, receive, transmit, Vcc. Dec 6, 17:11
  • DrFragle and MrShark Boxes Galore by DrFragle and MrShark: they've been slashdotted 😀 https://en.wikipedia.org/wiki/Slashdot_effect Dec 6, 16:11
  • DPS5020 and DPS3003 PSUs by Mai Mariarti: What are the pinouts for the BT module? Red, Black, Yellow and green doesn't tell me much! Dec 6, 15:37
  • IoD-09 Display from 4D Systems by Gln: Shipping to Europe is US $36 flat rate, so instead of $19.95 we would pay $56 for one..... ouch. Dec 6, 12:51
