    Nice looking project.Those pressure sensitive resistors are very expensive though. I couldn't find them cheaper than $7 each. Tip for makers on a budget you can make a rudimentary capacitive touch sensor with the Arduino and a 1Mohm resistor for each input.Instructable here https://www.instructables.com/id/Arduino-Capacitiv...And explanation of the library here https://playground.arduino.cc/Main/CapacitiveSenso...The good thing is that capacitive touch works through an insulator like plastic or silicone as long as your sensor is big enough.Another idea I had after watching the demonstration video is that you could use the duration of the touch to perform extra functions. Short touch switch on or off, longer touch fade the LED off or on. Really long touch turn all on or off. Double tap c...

Double tap change colour.Your project has given me a few ideas for a night light for my cousin's kids.Keep up the good work.

  • How to Make Power Bank on Your Own Easily

    The TP 4056 battery protection module doesn't do load balancing, so charging 3 cells from one module will not work well. Once the unit sees one of the three cells is at it's limit, it will stop charging or stop the battery giving power.To get this to work correctly you need 3 TP 4056 battery protection modules. One connected to each battery. The USB input from one module can be used to power the other two modules by soldering jumper wires to the +/- contacts on the USB end of the module.The output of the three modules can be joined in parallel to provide the power to the boost convertor.

    Cutting Aid Advanced

    As someone with fine motor control problems in my hands, can I offer some suggestions?Firstly I don't want to destroy all my kitchen knives to make them easier to use. My wife uses the knives too, so I'd rather have an easy to attach clamp. With the blade bolted into the aid, it's going to cause problems in my dishwasher.Most of my strength in my hands and wrist is around my index finger and thumb. Your blade position puts the stress between the middle finger and ring finger. Did you try different blade positions?The idea is good, but it needs a bit of fine tuning to be really great.CheersMaxx

    Scott, To fix your code you need to insert the following lines...Before the setupLine 21 int = triacVAL = 0;In the counter == 40 testLine 54 triacVAL = digitalRead(triac);Line 64 digitalWrite(triac, triacVAL);The reason it pauses every 40 cycles, is that on the test for 40, you set the triac low to read the temp, and it never gets checked again till the next interrupt 40 cycles later. The additional code looks at the state of the triac going into the test and stores it in triacVAL, then on leaving the interrupt it resets the triac to it's previous state.I don't have the components to hand to build a test circuit, but I hope this helps.

    Looks like a great project, but I can't find the plastic cube light in the UK. I have tried eBay and a few other suppliers. It looks like it would have to be 3D printed.I'll have to keep my eyes open in our pound shops.Thanks for the great idea.
