Looks Good, all the colours are visible at the same time. I wonder if a modified version could be used for sewing machine bobbins. Great work & neat lab!

Thanks for this new build. I still want to make it with Nano. This should help!

I was waiting for this! Thanks!
- ajoyraman commented on baweja_akshay's instructable USB Component TesterView Instructable »
Great work! I want to make one with Nano.I find that the arduino nano has the same basic configuration as your tester on the chain and a version could be built around this by adding the other components required. I fused both the .hex file provided by you and also a .hex file which was compiled from source using Atmel Studio. I looked for a response to serial commands. With Pin7 H/L there is no response at 9600-8-N-1. to VER.. etc. My current limitation is that without an USBasp the programming is via AVRISP. I am keen to get the nano version working. Any suggestions would be appreciated.

- ajoyraman commented on zakbobdop's instructable How to Make Really Cheap Pressure SensorsView Instructable »
I like your approach in doing projects with things lying around. Put your Sponge-Switch under the doormat outside your house and link it to a buzzer (work with batteries) and make an auto doorbell. Try turning this into a real pressure sensor by filling your sponge with graphite powder then compressing it would change its resistance. Will it work ? try and see. Best wishes for many more instructables from you11

Great project! There are two physical effects in action: the first is the eddy current rotating the magnet ring, and the second the magnetic flux cutting the coil to generate the emf.

Instead of 10 Ohms if you had used 1 K's it would have been a 12K earring set. Resistors are always lying around. Great work! You have my vote.

I have tried this with only a single tube. If you connect 3 X 18W tubes in parallel firstly this comes to 54W which is beyond the 40W rating. Also, as tubes in parallel may not start simultaneously whichever comes ON first is likely to get damaged. I advise you not to try this!

Good idea. Maybe a characteristic of the power bank.Can you send hhoto of your connections. AC power to powerbank and powerbank to 5v-12V converter and MI part number. there could be a work around.
