In a previous post I looked at an anemometer that I bought from AliExpress that was built around a cheap toy motor. I wasn't happy with it so decided to salvage the cups from it for use in a scratch built one using a bicycle hub. It's been an interesting project and had more challenges... Continue Reading →

Australian possums: In the heater, ceiling and their own houses
Possums have been a regular part of our lives. Many years ago, when we first moved into this house, possums had already made themselves home in the garage and in the ceiling cavity. There wasn't a door in the opening that goes under the floor and possums had managed to go through the opening and... Continue Reading →
My Build of the Soldersmoke 40M Direct Conversion Receiver
While I don't have an Amateur Radio license, I do find radio interesting. I often listen to the Soldersmoke podcast and look at their blog. I became interested in the Direct Conversion Radio they had designed. The radio covers the 40-meter or 7-MHz amateur radio frequency band. It is fairly simple and deliberately uses discrete...

AliExpress phone holder joins multimeter to make a stand

The first one was in 1978 or 79 when I was about 13 or 14, At that time what is now TAFE NSW (Technical and Further Education) in Australia ran short night courses for hobbyists. My mother went to quite a few including sewing, upholstery, carpentry... Continue Reading →
Railway spikes & reclaimed wood: Making coat and hat racks from recycled materials
Sometimes I find that a project turns out to be much better and useful than I expected. Making coat racks out of railway spikes and old timber has been one of these surprises. I really like the aesthetic of these, and I find them to be quite practical. While we already had 3 sets, I... Continue Reading →
ISD1820 audio module: Using the module for audio messages and silly sounds
I have had one of those cheap ISD1820 audio recorder and player modules sitting around for a long time. I thought it may make a fun message recorder to leave on the kitchen counter and see how it gets used. I was thinking it may be used as an alternative to leaving written messages, but...

Updated garage remote control case for wall mounting
We have one of those kits that converts a manual garage roller door into an electric remote control roller door. It’s been mostly fine, if you don’t mind doing a little dance in the house doorway to get it to open as it's at the limit of its range. Over time the rubber over the... Continue Reading →
New mailbox built mainly from recycled material
Mail delivery has become more important for us in recent years than it ever has been. While many communications have become electronic, more of the goods our family buy are purchased online as the option to buy locally is limited and in some cases is reducing. We are in a rural mail delivery area. There... Continue Reading →
