Thank you!

Thanks Mark!

Very nice! Did you make the case yourself too?

Thank you!

Great build! Good luck with the contest!

Thank you!We will be posting guide on making another object for our kitchen later.

Thank you!

Thank you!I did reference the work of Reyboz in the write-up which allows to play such good quality:http://blog.reyboz.it/2013/04/02/arduino-best-of-super-mario-bros-2-voci-arduino/After finishing the build I found two more interesting libraries:https://github.com/nathanRamaNoodles/MusicWithoutDelay-LIbraryhttps://sensorium.github.io/Mozzi/If I started from scratch again I would still use the work of Reyboz (first link) as it ideally suites the game.

Thank you!

Thank you for your feedback. This model is not rare in the country where it was made. I did have an empty shell but unfortunately I did have to buy another one around 5 USD that I gutted - it was shown on TV.

thank you for sharing. great build!

thank you!

Thanks. Parts are low cost:+ lego baseplate - $3+ 4 arcade buttons - $8+ 2 start/stop buttons - $0.86+ rocker switch - $0.41+ Arduino Nano clone - $1.94+ 1602 LCD + I2C module - $1.92+ batteries are free+ double battery holder - $0.47+ 2 speakers - $2.52 (or free from old tv)+ TP4056 controller - $0.28+ 5v booster - $0.40+ Micro USB breakout - $0.94 for 10pcs (it's cheaper to buy like this)+ 830 point breadboard - $1.42+ top face plate should cost no more than $3 in local CNC shopTotal: $25.18 including shipping to any part of the world (I took today's prices from Aliexpress)

Thank you!

thank you!

Thanks. Cheap Wacom tablet is all it takes :-)

Thank you for your kind comments!

Great rebuild! Well done!

Thank you!

Thank you!

Sorry to see you were not shortlisted. I voted for you!

Thank you!

Thank you and really happy that it worked for you too!

Forecasting algorithm is the following:Arduino Nano gets new data from BME280 sensor every 12 minutes.The measurement cycle is 3 hours. After 3 hours the range of pressure monitoring (max and min value during 3 hours) shifts relative to average values during the current range and current pressure value. Every hour the direction of pressure change with current pressure value are saved. kPa units are used for forecast calculation.Due to memory limitations of Nano the forecasting algorithm had to be simplified. But despite simplifications, it is able to forecast precipitation in next 12-24 hours even though the forecasting is now more pessimistic - the default value is "Cloudy Weather"."Sunny Weather" - current value of pressure is higher than norm by 7 points, pressure...

But despite simplifications, it is able to forecast precipitation in next 12-24 hours even though the forecasting is now more pessimistic - the default value is "Cloudy Weather"."Sunny Weather" - current value of pressure is higher than norm by 7 points, pressure is not falling and difference between min and max values during the last 3 hours is not more than 2 points.Possible precipitation "Rainy Weather" - current pressure is 15 points lower than norm and difference between min & max values is more than 2 points OR Pressure is falling and difference between current value and norm is 3 - 30 points.To improve the quality of forecasting it is recommended to change your "altitude" in the main code file. You can get your altitude for example here: https://www.daftlogic.com/sandbox-google-maps-find-altitude.htm

Wow! Thank you for sharing! It looks great!Thank you for such valuable feedback. You are right on all points. Here are some responses:+ Clock date and time were set using the standard example script from the 1307 library (added a note on this into GitHub Readme). As you might have noticed, the current code uses up all memory so we were not able to add the initial date/time setting. In the future we will create a small "initialise" program that will erase alarm clock memory (to prevent garbage data like you got when you set alarm first time) and set the right time.+ Thanks for pointing out on the right lib. We re-uploaded the correct lib and fixed the links on GitHub.+ Yes, BME280 is probably the best you can get at the moment.+ Your LDR is a more expensive type. We used the mo...

Yes. The clock runs while charging. USB power can be applied permanently.

Thanks. The forecast is based on well known calculation process, just like people used to do using barometers.

I have not measured it but it is of course days.

The circular PCB is a decoration. Electronics inside are very simple even for a novice. thanks for the warm comment!
