Great project and very good presentation. Excellent video with a quality voice over.Best wishes for your future work.
Great project. Has many applications for other storage areas. Well presented with excellent explanation.
Great project. This idea could be added to any other alarm system. An alarm trigger from any other sensor could be use to initiate a phone call.
McGyver would be proud of this Class A audio amp. Minimum amount of readily available components, great project to get started. Very high probability of the construction working on the first attempt.
A pleasure to see old school thechnology put to such effective use. this project is indeed a tribute to Frank Hornby the inventor of Meccano erector sets.
A very useful project. i will make something similar.
Great educational project. Very well presented. Excellent graphics.
Good presentation. Clear, short and to the point. Good video and clear audio. Leep up the good work.
Very good explanation. I have used something like this in a progect. I changed the resistors and used forward biased diodes to get 0.6V drop between switches I was only using 6 bush buttons but it was necessary to calibrate the voltage ladder to get reliable detection.
Make that "Radiogram Great again". Great project to make something useful for years to come. No batteries no repairs.
I had similar problem with poor lighting. I used two 12V led lights. one oe each side.
Thank you for an informative and very useful article.
What and excellent project. A useful, simple but beautifully made woodwork table.I will make something like this.
Very clever and useful piece of kit.
Great Demo Project. Uses input, output, Serial monitor, timing and if statements.
Excellent project. The idea has many wider applications. For example helping people with limited mobility.Step 6 part 3Have a review of the circuit drawing regarding the relay contacts NO, NC and J1.
A really great re-purpose job. I trained on valve equipment and worked for Marconi as a Marine Radio Officer many years ago. It is quite amazing to see that that Valve (Tube) Look still turns heads. 3Kv on the anodes could really make those beauties glow. The only remaining design mod to add is to simulate the LT lighting up the cathodes nice and slow while bringing on the audio gently. A few simulated crackles and TRF whistles might add interest.
Many thanks for the advise and very clear instructions. I will have to do this fix on my machine.
A very helpful project and an excellent presentation.
A very good example of dealing with pre-defined command words [ swtch and switch].
Well done. A very useful project. I would suggest that a that a schedule be set up to test the system on a regular basis. A practice run should be done by at least two adults in the household. Fuel should be safely stored in approved containers.
