You might want to swap that hose out for good stuff and clamp it on before that garden hose cracks, falls off and dumps all the water into your retaining wall.

Bung: You should protect white drums from UV. They will become very brittle after a few years in sun. Blue or black last a lot longer.

 

It is in a very shaded spot that never receives direct sunlight.  But I hear what you are saying, I was hoping for blue but I got these for cheap.

insane: I'm guessing a retaining engineer would frown at the additional surcharge applied to the wall. Posts look fairly slim for the height without the additional 800kg.

Wifey has been asking to do something similar to reduce our water usage. Today's rains were biblical and would have provided enough water for the garden for weeks if not longer.

 

Underneath the barrels is about 200mm of clay based topsoil and then volcanic rock.  If you took away the retaining wall the rock isn't going anywhere.

Bunnings was out of hose clamps (well they only has SS ones which seemed a bit of overkill).

 

The garden hose will survive till next summer when I can upgrade.  Was thinking of throwing a tap between each barrel so I can isolate if need be.

Ok cool, just thought I'd mention it as I've recently engaged an engineer for some retaining work I needed, and was surprised at the difference in design standards between what a geotech engineer and a landscaper thought was adequate. Was a bit shocked at the size of posts engineers calculated were needed, though they are probably calculating for a design life of 50-100years, vs the landscaper who only needs to it last as long as his business is solvent.

I did something similar last year with a downpipe diverter and just one 250L drum. 250L might not seem like a lot but it allowed me to wash both the cars every few weeks through the water restrictions that were in place last year.

not overkill, the non stainless ones will rust up in no time outside. I used many on my drip system because the plastic ratchet ones all failed and the non stainless clamps all turned to crap. Order some stainless off aliexpress and way cheaper than those overpriced cards with 2 on them at bunnings.

My DIY-ish coffee bean roaster, with a cheap basket from Ali, and the metal surround/stand for the whole thing off an old microwave. Video of it in operation.

I am in the process of building a 64x32 RGB LED matrix as a wireless smart home warning display using a Raspberry Pi Zero 2w and MQTT protocol. It's not the most energy-efficient solution, but it looks spectacular and can't be overlooked - like neon signs in New York. And we won't forget i.e. to put out the rubbish once Home Assistant has evaluated the city's garbage collection calendar.

Ooh, this sounds cool. Any further details? Are you actually building the matrix or using something off the shelf?

The pico w may be a better option, I have not had a stable output when running matrixes off the pi's - lower PWM freq and they are often glitching unpleasantly. I gave up using an ESP as well as that wasnt glitch free. I would hope that the PIOs on the pico might give it a hope of a stable scan rate for them, a

No, I don‘t invent the wheel a second time. It‘s derived from this project. You can use the cheaper panel (64x32) from „waveshare“ as well, it‘s compatible/adaptable. For garbage collection you need an interface to the service at your location like this. But there are plenty of other things to display as well.

This is known and depending of the used Pi model, you have to adjust wait cycles in the config file to prevent this (especially from RPi3 upwards). The processing power of the pico w isn‘t sufficient when I like to extend the panel to 64x64 by a second one. The main power consumption is from the panel, not the controller.

Recently started to do some more work in the backyard, finished off the lawn and garden edging, and got in the lawn mix to lay down the lawn. Took about 7m3 of of Living Earth Ultra Lawn mix to level out the area, as it was about 10-80mm off being flat, and with the area, now level i rolled the area with a roller weighted with water, then gently scuffed up the top of the surface to help the grass seed get better contact.

 

I used a product called woolgro and i went with the tall fescue variety as its pretty hardy and drought tollerant, and as i wanted a quicker/easier product than just plain grass seed. i was tempted to try hydroseed but after doing all the rest of the work in the backyard we decided on the woolgro. Its a thin woolen roll attached to a paper backing which has the grass seeds attached, you roll it out and cover it with a 5-10mm layer of lawn mix, then just keep damp for the first few week to encourage the seeds to sprout.

 

So watering morning and night, away i went. hadnt seen anything after 10 days but on day 11 on close inspection i was getting some tiny shoots coming through, by day 14 it was pretty noticeable while standing and the last photo is from day 21 which was last friday.

 

Just have to keep watering it to keep it green and encourage the grass to thicken up.

 

Still have a bit more work to do on the fences, and vegie gardens down the back but hopefully by xmas it will be all done. just have to wait on the grass now before i can do much more

 

 

 

Pre edging on the left side and it being leveled out

 

 

Starting to low out the woolgro mats

 

 

all laid out and first water

 

 

3 weeks later
