Been bitten by the electronics bug lately and built a small lightup toy for my little ones which i've documented at Instructables for those who fancy having a go at it themselves. I've been amassing components so plan many more builds.
I setup reporting for my EPever solar charge controller a while ago using using the following guide at sporadic projects . It works but have been hankering for something a little more/different and saw a posting recently of someone using grafana and influxdb to report on their PIP based solar setup so i set about recreating this and in all honesty it wasn't as bad as i thought and after a few days i've gotten something up and running. The first step was setting up my pi, i decided to reuse a aging pi1 which caused some issues as i couldn't install things from the standard repo's so it needed a little more tinkering. I documented this as i went so i hope this helps others using it on a pi1 also. The below shall download a precompiled influxdb setup and install it. It will then add a custom repo to your sources list and install grafana and then start it up and enable it at startup. Lastly it shall install php and the curl library for php and the...
First off thank you for your purchase! I made this device for working with small devices to keep powerbanks/power supplies alive as they can frequently auto shutoff if they believe the device is not on as it is drawing so little power. Once assembled the device shall look as per below (resistor colours may vary and also the case colour may vary if you've ordered one) The 3D case design is on Thingiverse Once inside the case the assembled unit shall look as per below So enough of the end product, lets look at what the kit shall look like I have where possible labelled the parts in the packaging but the current shipping parts are coloured as above which makes identification easier. Assembly notes The resistors have no polarity so can be placed in either direction. The capacitors have a polarity which can be identified in two ways. The longest leg is the positive side and also the negative side has a white strip down that side. On the PC...
I've switched to prusalink/prusaconnect recently from octoprint and missed the nice homepage integration so have knocked the following up, you just need to update your IP and api key and you should be sorted. Thought it may be of use to others. Initially there is no api key generated on a prusalink install and it will be blank, you just need to click reset and it'll create this one. This won't affect the printers connection to prusaconnect if your using that also. I am using pi zero's but do not have them powered from the printer board so i can power the printers off when not in use. When you do this however the status that then gets returned is ERROR. I've remapped that to show powered off which works in my case but you can always remove that part. I've used the additional field option so that the target and actual temp of the nozzle and bed are shown on a single line rather than taking up 4 lines. As it's a list you can just append more onto the end. I...
