When you work out you need to repair your muscles for growth with quality protein.
Quality protein comes from meat 🍖 but you aren’t always near a stove to cook a steak 🥩 or eggs or have refrigeration cooling for cottage cheeses, etc right? We have an answer to the problem!!
Making preserved meat is the answer this is called Jerky or Biltong.
If you are concerned about the fat content choose venison like: kangaroo (🇦🇺), ostrich (🇿🇦) or deer (🇺🇲, 🇨🇦, 🇬🇧) or whatever sustainable wild meat 🍖 you can get in your part of the world 🌍.
Just Google the spices for Jerky or Biltong as there are so many options.
To get a quick do-it-yourself (DIY) kit which will take no more than 10 minutes to install on an enclosure of your choice (from your local hardware store like Home Depot, etc) go here, the next cheapest version on the market will cost you at least $1500, ours is much cheaper and found here:
Today I heard an awful screeching of tyres near my fence. I immediately jumped onto my AI CCTV footage and caught this hoon (a colloquial term for a road hooligan)…one day he is going to overcook it and come through my pool fence. I just hope and pray that nobody will be home swimming when he does. Point is, it is a very expensive car driven by somebody with very little common sense, see a screenshot from the video here:
Notice the spin tracks after one revolution by this hoon caught on video.
As usual this got me thinking, this time about Robert Kyosaki’s book and the lesson in that book, which is that – rich people aren’t necessarily the brightest in society.
Take this fellow in the photo below he told me that he does “concreting” for a living, which requires a 6 month certificate to enable a person to do that in Australia. I consider myself a reasonably educated person, I am an Engineer with 2 master’s degrees and a Ph.D but I am not rich in the financial sense (a bit like Robert Kyosaki’s one father in his celebrated book entitled, Rich Dad, Poor Dad). This tradesman is clearly doing well and ‘good on him‘ for that (no ill feeling from me – only respect for what he has accomplished in one area of life). However, the point is, never assume that somebody driving a brand new Ferrari is a brain surgeon or a high-powered invest banker, etc. Wealth thus has very little to do with ones intelligence or common sense. A good lesson to bear in mind.
Let’s see you might have guessed on of the following:
* Facebook’s artificial intelligence algorithm that feeds off people’s desires only to serve them a stronger dose of what they want. Watch The Social Dilemma Doco on Netflix to understand what I am referring to.
Actually you would be completely mistaken it is actually the power network! You didn’t think of that as a first guess right? Well it is, based on the mathematical models that describe it and the very complex interactions of everything that connects to it.
You may no doubt have been following all the food desiccator evolutions on this blog!
We started by putting a incandescent heat lamp and a desk fan in a plastic box with some holes drilled therein for ventilation, this was revision 1. The latest unit uses a bathroom venting fan and complimentary vent plus Arlec Bluetooth hub+temp&humidity sensor + switched plug socket. This all in a food grade plastic box with a basket that fits snuggly therein from which to hang the paper-clips. Recall these were bent into an S-shape for hanging up the meat to make either Biltong or Jerky.
The basket can have some aluminium fly-screen laid into it or shade-cloth laid into that basket and then fruit can be laid thereon to dry. I did that with a couple of sliced bananas and think this is my second most favourite snack, after biltong!
The ‘secret sauce’ controller is a controller that can switch the heat source every few seconds, giving better control in making your dried foods. It also allows all interactions via Bluetooth from your mobile phone and if you connect to your local Wifi will show progress on a webpage, how cool is that! It also uses RF to control a plug socket so no electrical connections required. This is the state-of-the-art. If you want to buy a plug and controller it costs $100. Leave a comment we will get your details for an order. You are really going to love it! 👍🌟🍌
Many folks are intimidated by the electrical aspect of making their own machine, rightly so it is a silent killer. This post is for such people. Get the fellows at the hardware store to fit a lamp holder with a plug socket as well as to the fan. All you need to do is cut a hole in the plastic box for those sockets to reach an external socket adaptor. Thus no wiring just a bit of assembly.
It is important to find a basket or rack that fits snugly into the box for either resting the fruit on or hanging the meat from, as below.
I recently found a ceramic bulb of 75 watt heating capacity. This works in high humidity environments. Note: The Grid Connect controlled socket – the one with “Smart Plug-in Socket” printed on the box within the above picture, is the one used for this heat source in this machine. The fan remains on during the duration of the process to vent out the moisture that is drawn out by the heat source – this is what the desiccation, or dehumidification is all about.
This just keeps getting better and better as technology advances! Now just to choose your spice from the websites by searching for “Crown Biltong Spice”.
Note: It’s probably a good idea to have your machine checked by an electrically qualified person, just to be safe.
A few lessons I learnt to bear in mind when using this Arlec equipment:
1) The setup requires you to be near your Wifi router with Bluetooth enabled on your phone
2) The temperature set points (corresponding to the values read from the Arlec Bluetooth enabled temp and humidity sensor are in degrees Fahrenheit and not degrees Celsius). Conversion of ON and OFF set-points for the Arlec Smart Plug-in Socket are below:
3) The temp and humidity sensor update rate can be changed by pressing the little button on it and watching the frequency change from the default of 30 min down to 5 min.
4) Most people struggle with getting the temp and humidity sensor to get registered with the App. It is important to press the button on this sensor for about 5 seconds until the red LED flashes rapidly and then to select Auto sync in the Smart Grid App on your phone.
A cool video of a great bunch of people who have a keen interest in building the machine using these exact parts is below. It actually is a heap of fun when you do this as a team, help each other out and treated it as bit of a “production line”:
A really nice South African actor that I watched growing up has now made some YouTube videos about the meat aspects of making biltong/beef jerky. He is an actor so will do the preparation better justice than me. I don’t use vinegar, as I don’t like the taste that it introduces into the final product. I only lay the raw meat in the biltong spice (Crown National – Safari Biltong Spice), which actually comprises: 1/3 part salt, 1/3 cracked brown pepper and 1/3 cracked dried coriander seeds. I lay it in a Pyrex dish, sprinkle half the spice over the one side of the meat, turn the meat over, sprinkle the other half of the spice on that side of the meat and then place that in the fridge for 24 hours with a cover of sandwich wrap (“Glad” wrap) to keep any other flavours within the fridge from permeating the meat – as he says “it isn’t rocket science”. Make sure that the “Glad” wrap doesn’t touch the meat and is pulled taut over the Pyrex dish. (Note: In Australia Jindurra steak costs only between AUD 13-20/kg depending on the cut and I have never had an issue with it: https://www.canstarblue.com.au/groceries/supermarket-meat-awards)
For dried fruit look at the following post, it is found under point numbered 17 in this post:

As an engineer (electrical and electronic) mathematics is an integral part of what we do (pun intended 😀)
I find it so sad when young people choose comfort over logic when making subject choices at school. I hear things like ‘I don’t like maths or physics’! They then later discover that they have an interest in a field of work which requires these very subjects. The path is then incredibly difficult for them to reach their aspirations.
Make no mistake, either of these subjects can be hard, especially if you parents had no interest in them at school and you have a school teacher that is also ‘no good’ in this space – as I had in a maths teacher in High School. Actually my high school as a whole, was pretty much a disaster. So even if life deals you a tough hand of cards persevere and you will eventually prevail.
I always loved science and chemistry but didn’t love mathematics due to a “shaky” introduction to the subject in high school. I consider myself an average bloke but have prevailed in my academic goals and love mathematics now!!
I was so impressed recently when I found a mini hi-fi system that a neighbour was throwing out and came across the following video post that tells one how to trick a car’s cd-player into accepting an auxiliary input and thought that I could stream Spotify through this mini hi-fi system. (Note: always switch off the power and disconnect the plug socket before attempting this).
There were however a few problems when I tried this with my newly “acquired” hi-fi unit:
The CD player on this unit was clearly the reason it was thrown out in the first place, even though the radio still worked, it was older an Analog Radio, not the newer Digital Radio, which is abbreviated as DAB+. This older form of radio can be scratchy depending on reception etc.
The unit had a tape player which have long since become obsolete.
I thus set about finding the “service manual” on the internet by looking for the model number which is usually found on the back “nameplate” of the unit and then searching for that name and service manual on the internet. You can see this nameplate in the first image on this post. You have got to love the internet and what is available on it!
I then had to look for the CD signals on the circuit diagram for the left and right channels on the various connectors, on this hi-fi unit these were marked C/R-in, C/L-in and D-GND. I bought a good quality auxiliary cable and cut it in half. I exposed the red (right channel) the white (left channel) and the shield / signal ground (“earth”). I then soldered these three conductors from the auxiliary cable to the purple-coloured points (shown on the diagram below) to the nearest solder points on the printed circuit board (PCB) by tracing them from the connector numbered CNP303 using a multimeter on the “buzzer” setting (continuity tester). The CD player had an issue so the sound that came from connecting to these connection points was way too feint. I then decided I’ll rather connect to the more generic signals which come from either the CD or the Cassette Player (abbreviated as “CASS” on the circuit diagram) or the Radio (abbreviated “RAD”). These are thus the yellow-coloured points on the circuit diagram named L-OUT and R-OUT, below:
As per the instructions in the Youtube video if you use the CD-player you have to “play” a blank CD in the CD player. When using the cassette player you just have to push the Play button and Viola, it works! High quality digital music using the amplifier and great speakers from a hif-fi that would end up on the landfill. I gave it a new lease on life! Sustainability at its best….
There was a bonus. Spotify allows one to have an old mobile phone connected to the same Wifi as your usual mobile phone and then allow you to direct that phone to play your music. I thus used my old mobile, connected to the same Wifi router as my current phone and then with the Auxiliary cable plugged into this old phone I am now able to stream great music to this old phone. Sorry but that was such a great revelation for me. I also now have a great use for old mobile phones, I can literally find an old radio/cassette player/CD player connect that via an auxiliary cable (as above) to an old phone in every room in the house and with these connected to the same Wifi network. I thus have a museum of old technology serving a new purpose – bespoke music in every room with guests connecting to my Guest Wifi network, then able to stream their own choice of music in whichever room they find themselves. This is truly not wasting older technology, I am just repurposing it…..I love it, I hope you do too?!
This was one of the more gratifying projects for me, as I feel it improves people’s comfort levels using technology and simultaneously saves the planet at the same time, without costing a cent!
Also, look for the iHeartRadio App in the relevant app store for the operating system on your phone and then you have great local Australia radio stations to listen to 👍
I loved this project so much that I took an old car radio, the Sony CDX-S2210S and “hacked” the output CD signals so that I could use this in my pool box as an entertainment area, sound system for around the pool. Again I found an old mobile phone and installed Spotify whilst including this phone within my family group. It obviously is connected to my guest wi-fi network.
A bit of a trick with this CD player is that it generates an error signal if you place a blank CD in the player. In this instance you actually have to use a playable music CD. The radio then attenuates the output from the actual CD player in favour of the hacked Aux. input signal. My wife had a coniption when the auxiliary cable disengaged out of the cellphone due to its cover messing with the seating of the connector and it played the CD rather than the Spotify signal. I may actually superglue the auxiliary cable into the mobile phone headphone port to prevent this from happening again 😜.
Just being able to repair any old machine using Arduino controllers is a great way to save the planet and save heaps of money, just read how a business card machine was repaired using a Arduino Mega 2560…so cool:
