Update September 2018 I read about the most convoluted ways to back up SBC systems…. some back up only data, some use arcane commands to do the job – few if any are a single click job for a complete backup that can even handle larger or smaller SDs. That is except for RPI-Clone. Below … Continue reading SD CARD Backup
In today’s postbag, a pair of the new NanoPi K1 PLUS boards from FriendlyARM. These powerful H5-based boards look interesting and in this case came complete with heatsinks, Pi-size transparent case and handy FTDIs for programming.
In today’s postbag, the new Feeltech FY6800 dual channel Signal Generator, complete with UK power lead, two bnc test leads, USB lead and bnc-bnc lead. However the unit came with no instructions or other paperwork. I assume a manual will follow later. The unit arrived well-packed via FedEx. Lovely to look at and extremely comprehensive … Continue reading FY6800 Signal Generator
I mentioned recently in an entry aimed at beginners, that I’ve been installing “the script” and my ESP8266 code on various devices. I now have a backed-up Raspberry Pi 3B+ board set up for testing, with the latest Raspbian and fully up to date Node-Red nodes including my own and running “the script”, talking to … Continue reading The Nano Peripheral Update
As many of you know, I don’t have a great deal of time for Arduino for WIFI/Ethernet – I cannot tell you how many months I wasted on those daft cheap Ethernet boards for them which never really worked reliably no matter what I did – so I probably have a mental block by now. … Continue reading Arduino Peripheral for HC2019
I’m often asked about setting up MQTT, Node-Red etc. on the likes of Raspberry Pi, NanoPi or similar, with a view to controlling ESP8266 devices. Novice readers start here Usually it is difficult for me to see this from a beginner perspective, but having spent 2 months in hospital thanks to an untimely stroke from … Continue reading The Script and ESP8266 Code for Beginners
Thanks for your continued patience, everyone. Following on from my little mishap in December, which has effectively prevented me from blogging or making YouTube videos from mid-December onward, I plan to start doing some blog writing with more detailed blogs and videos to follow perhaps in April/May when I’ll also have access to all my … Continue reading First reviews of 2018
In case anyone else (like me) has been sitting on the shelf over this one – and would like to have a go at an ESP8266 mesh… we’ve been having a play. Regular readers may recall I wasted the better part of a year with those AWFUL NRG24L01 boards trying to make a mesh and … Continue reading ESP8266 Mesh Experiment
Ruideng just sent me their latest power supply and case… or rather, the kit. The control board is assembled as is the display board. You get case, fan, switch, fan PSU and bags of nuts, bolts, washers and wire. What could possibly go wrong?
Voltage and current monitoring The INA3221 or rather one of the boards based around it, allows for a single power input and up to 3 power outputs –each monitoring voltage and current and all done via I2c. You can (almost) think of this as a triple INA219 – the bidirectional current power monitor. If you … Continue reading INA3221 v INA219
This is the story of the evolution of an uninterruptible power supply for the likes of Raspberry Pi etc. It takes over where various posts about UPS leave off, the last (detailed) entry being “The Dog’s Breakfast” – in the search for a low-cost UPS and for individual micro boards and having been less than … Continue reading The Kitchen Sink
This started off as a simple discussion on UPS for the likes of the Raspberry Pi and other micro boards but developed into so much more. Some great conversation, some ideas – and a project at the end which could fit a lot of requirements at very low cost. Read on…
