Introduction (Latest update April 03, 2019) Minor update here – I’ve gone back to SDK 2.1 for now. Sick of reading about other people’s home control? Want to make your own? Got some electronics and software experience? You’re going to LOVE THIS! Rock-solid home control, flexible, low cost, DIY.
As I normally rave about RPI-CLONE – I thought I’d share the dirty laundry this time. ** Update Jan 13 2019 It is looking increasingly likely that the issues I was having were power supply related and one bad SD card. I’ve just finished my 7th successful backup-clone since removing the intermediate battery pack to … Continue reading Raspberry Pi RPI-CLONE Issues
That was in danger of becoming a very long title. I just bought this display/case combo for Raspberry Pi – I’m pretty sure from Banggood (no clue in the package) – but anyway as they have the driver links and the driver was not included in the box – see over the break. The links … Continue reading 3.5 inch LCD Touch Screen and RPI Case
Upgrading my IP cameras again. I now have a brand spanking new, white Alfawise HD Smart WiFi IP camera from Gearbest and it is lovely (and cheap). It is made from what at least looks like powder-coated, cast aluminium and I have to say, looks quite solid.
I must say it does feel a little like Christmas already in the frozen wastes of the Northeast of England. Partly because it is bag-bitingly cold but also as the post came this morning with my new watch (the mother of all watches) which I’ll detail shortly – but first…
Having discovered some less than ideal historical settings in ESP-GO, today I’ve removed all commands which could OUTPUT to GPIO0. a throwback to the old ESP-01 days. I’ve also updated some default input bounce settings and improved the little-documented DEBUG2 command which lets you see the state of inputs on the serial terminal (I abandoned … Continue reading A very busy week for Home Control
Having satisfied myself that RPI-CLONE does a good job of creating backups of Raspberry Pi (no guarantees you won’t lose data but it hasn’t happened to me yet) I started the search for a solution for other boards. I find the Orange Pi +2E to be a particularly nice piece of hardware, but useless without … Continue reading Easy Backup 2
This is a post from back in March 2017 – but as I’d forgotten all about it, I thought you might like to share my renewed enthusiasm if you are a Node-Red user. NR introduces non-volatile flow and global variables in version 0.19 but if that doesn’t work for you, well there is always this:
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
