Some cooks use it BBQ and also home brewers as it is more accurate.
We just removed that Fahrenheit display module…Anyway, thank yo for the info.
How is it more accurate?
It isn't more accurate at all!
The F scale has a higher RESOLUTION (180 degrees between freezing & boiling point) vs C (100 degrees).
With digital temperature measurement, the display is usually in 1/10 of a degree. Difference in measurement resolution down to 1/10 of a degree makes no real difference in heating & cooling processes - in either F or C scale!
But ACCURACY of measurement is a different matter - determined by the instrument used.
Optimistically in this case it stated as an accuracy of 1F.
A higher degree of resolution never can compensate for any inaccuracy of measurement.
If F is used here in heat processes, it is because either that is the measurement available on the instrument or controls used, or it is what the person reads from old or F based advice on websites. Conversion to C is simple.
In heating, relying on such a cheap measurement device would not be advisable.
It can't be used at temp above 275F, so useless for BBQ.
Using for brewing believing it is more accurate than a C thermometer is pointless.
Most heating or cooling processes can't be controlled to such a fine resolution or accuracy. Many appliances only regulate temp within many degrees (of either scale).
@INFIDEL: Maybe I could have worded it better. Not more accurate, however Fahrenheit uses a larger temp range.
@thesaver: It's a common misunderstanding - between accuracy & resolution, so just clarified.
Better resolution without adequate accuracy is useless.
With modern measurement to a fraction of a degree, the choice of scale isn't important.
Choice of accuracy in measurement instrument is!
But heat / cooling controls are never accurate to anywhere near 1F/1C at the product.
Accurate measurement & control is usually illusory in most processes. So trying to achieve what is not possible is pointless.
My parents used an oven with a F scale analogy thermostat control marked in 50F increments. Their parents grew up with a wood fired stove with no control except experience. Still produced great food.
A modern goal of precise measurement & control can become pretty obsessive for some.
I once thought correct measurement was vital - in producing award winning products. A newspaper photo showed my dedication to accurate measurement.
I later learnt my measurements looked, but weren't actually that accurate. The products still won awards!
Besides - I can be dyslexic with numbers - above I reported the max temp is 275F, but is 257F! Either way, the thermometer (removed from this Deal) is no use for cooking on a BBQ.
Sorry, we did not realise that..We post this display Fahrenheit display module because it is one of the best seller..
Most countries in the world use Celsius (℃) temperature, it seemed three countries in the world (the United States, Myanmar and Libya) usually use degrees Fahrenheit?
Not Libya, Liberia
noted with thanks
@ICStation: Also, as a side note/ a bit of trivia, only three countries – the U.S., Liberia and Myanmar – still (mostly or officially) stick to the imperial system. However, Liberia is trying to change to the metric.
Well that's just Libellous😄
A few other countries also use F.
But Myanmar doesn't use F!
When reporting a maximum temp in UK & apparently Canada, it may be reported in F. Just sounds more dramatic that way.
It's for the people here that use ass instead of arse.
this is…incredibly niche.
Do you think it is really that weird? It's like Meccano or Lego, a kit you can solder together to make your own radio.
I'm tempted, but surface mount soldering the IC on the back challenges my shaky hands and poor eyes.
Do you think it is really that weird?
That said niche, not queer.
Well buying & waiting for this kit, having the necessary tools, assembling & soldering - to produce a FM radio that is already available in your phone seems a lot of bother.
Agree - pretty niche market for this FM kit. Plenty of more interesting options. I've bought from this site.
And I've assembled many electronic kits. But know my eyesight now could be better to do the job. I use a magnifying light & a rig to hold the circuit board.
Like, I’m not going to war about this, but I raised all my kids to do basic electronics projects - wiring up some leds so they can light a lego building, and connecting car stereo speakers with plugs and stuff.
And they certainly have made up an extension cord by wiring a plug with screw terminals in.
I just figured a bit of basic electrical stuff was the same learning as showing them how to cut a sheet of ply or sand back a charity shop find like a coffee table or shelf.
The surface Mount soldering on this is a bit tricky, but everything else is lego level skill, not something I would think of as unusual for a 12yro?
Thinking about it, I realise 3 of my 4 kids never did an electronic project as a school assignment (ages 12, 15, 17) while the eldest, now 19yro did. When I was at school it was yr6 or 7.
I wonder if it has been not required for a long time?
@mskeggs: Flashing LEDs are always easy fun young beginners projects. Something they can show others & feel the accomplishment. That encourages them to build more.
But with the introduction of microprocessors & more complex chips, many kits became unnecessary, or more complex (surface mount devices, required special handling, & programming).
Built my first 8 bit microprocessor unit in the mid 70's - with 8kbit of RAM! Was terribly expensive! I was working during holidays in a semiconductor supply business, so had plenty of cheap parts.
I've still got a few unbuilt kits, bought cheap or even free when Dick Smith exited the kit business.
Apps & websites have now taken the place of plenty of kit construction.
@INFIDEL: Off the back of these comments I had a chat with some of the kids. They are open to software hacking, like
breaking DRM and basic hardware hacking like making a cable that somebody else says should have a different pin out, but not happy to measure voltages on a interface.
My eldest, who is female, and was the one who did the school project to wire up lights to a battery was actually the one who was most hands off. She also has the only >$1000 phone, so maybe that’s part of it. I’m happy to have a go with fixing stuff, but send it back in warranty.
@mskeggs: Ah, if there is a site or video of a mod - it is popular. But taking basic voltage readings… Boring!
@INFIDEL: I get it, cause the stuff we talk about is hackaday or Kickstarter style stuff - I shouldn’t pretend like this is everyday, more like once a year a kid says “
Hey, can we make that Kickstarter thing ourselves” or can we make the fridge go on at 3degrees (maybe me for home brew)
So we really don’t ever make anything hard/interesting ourselves.
But dumb stuff like the confidence to make an extension cord to size, or put an AU plug on a UK hair dryer is something I really like, and lots of folk lack.
@mskeggs: I don't understand why, can learn how things fuction from the inside-out down to the component level. I woulda thought that was an invaluable learning tool
Thanks OP. Bought a couple of DIY kits from your website.
Thanks a lot for your support:) Guess the order is about radio kit, music box kit, xmas tree kit and igiter kit. We willl add extra little kit there. Have a nice day!
Cheers!
Is this something like the Dick Smith kits of yesteryear? Been looking for a way back into all that kinda stuff.
You guys have a local warehouse or do we have to wait for it to come from China?
Yes, but it includes a surface mounted chip which breaks it, in my opinion.
I’m a bit of a butcher with soldering, so reckon only pin mounted components are suitable for beginners.
If you go look on eBay, there are reasonable equivalent kits to the old dick smith ones.
Jay car also has project books and kits, but not as good.
Hey thanks for the tip, any recommendations on ebay sellers for this stuff? I agree that the surface mount would be too advanced for me.
It’s hard to find a good option.
Jay car still make their short circuits book/kit, but it is expensive and I found it not very good.

Maybe something like this? Solderless, so safe, and pretty easy.
https://www.ebay.com.au/itm/301802241871
Yes…
Sorry to let you know this kit need to be shipped from Shenzhen in China.
Normally can be arrived in Australia in 2-4 weeks via regular post.
Hey ninjataki, you should get into Vintage Hifi as I did about 10 years ago. Mid-70s to mid-80s is the 'golden age' and some of it can be had for very little. No super-fine soldering required however you'll be exposed to mains potential voltages so you'll need to learn the basics. Best thing is that once you've repaired a nice piece of gear you get the enjoyment of listening to it and if you don't want to keep it then you can usually make a decent profit when selling it on… even if you do feel the need to chop the lead off for safety/liability reasons.
Thanks for the advice, I'll start out with the basic kits again (led stuff etc) then possibly go there cheers 😃
Rep please know your target audience. We don't use Fahrenheit here.
