This will serve as your + connection.\n Bend one of the resistor's leads into a flat spiral such that it can make good contact underneath the magnet. Solder the other piece of magnet wire to the other lead and feed it through the non-center hole. If...

... for the negative lead. This way, you won't need to add a resistor to the LED. Additionally, to make this work, go to your Raspberry Pi config and enable Serial by going to Advanced Options and enabling it via menu option Serial. ... Happy printing!

I have used a small piece of a through hole resistor's leg that was cut off. * Use one of the pins from a molex type connector that you extract from the connector, these usually get wires crimped onto them. Fold your TC wire over once or twice and...

A gearing system is required to keep the generator functional, or resistors can be used to create a lower operating speed. While the design calls for a wooden frame, a prototype was created using an old bike turbo. Sustainability was in mind, as...

If you are a better EE than I you could certainly buy just the display and some resistors and skip the I2c backpack altogether, opting for some protoboard or even posterboard to hold the display in. If you're going that far you could also snag a...

Inside is room to store jumpers, USB cable, power adapter (for use when not connected to the host computer), and a small parts box for LEDs, transistors, resistors, and basic chips like a shift register. There should be room for most components that...

From my experience, you WILL need a 10K pull DOWN resistor between GPIO14 and ground to hold the pin low when not activated since the touch switch pulls things high to activate and doesn't seem to pull the pin down. Otherwise I was getting flaky...

You can also add a retarder that gives Noctua as add-on plug (BTW this is only a 100 Ohm resistor in serial conn.) to silence the fan to around 1400 rp/m. Most of the time it working really enough for me. But then the filter efficiency drops to 90%....

The wire connected to pin 3V needs to connect to the pin closer to the tiny red resistor on the motion sensor. The wire connected to the GND pin on the Micro:bit needs to connect to the final pin. If you'd like a more technical explanation of the...

The LED tea lights are equipped with CR 2032 batteries and can be connected directly to 3 V without a series resistor I bought a battery box for two AA batteries and used it as a voltage source. The tea lights are disassembled and the upper parts...

I have narrowed down the errors a bit, and it appears to be caused by the built-in resistor. If anyone has a solution, please let me know. Until then, I advise against printing the cover with the touch sensor. Here are a few implementations of my...

but later I just solder some 3528 warm white leds plus resistors on the perfboard and adjust its power input to meet the same 12V DC power.12 DC power supply (if I have time, I can try to dig the unsorted components bags to find the dc/dc boost chips...

At 200% scale, I was able to, fairly easily, fit four 5mm LEDs inside, each with an 100 ohm resistor to allow the 3.2v LEDs I chose for the project to be driven off a 5v USB power supply via a breakout board. Print the preferred main body and cap...

You can use the ground and 3V3 rail on the RPi to power it, but you'll need to have an appropriate resistor installed inline.It's running the following software: Raspberry Pi OS, with Desktop (it's slow on the Pi Zero W, but it was extremely helpful...

So CS1 is for the Left Eye (Pin 12) and CS2 is for the Right Eye (Pin 10) He also changes the resistor to 68 Ohms so you can run the LED off 5 volts (Why? But do it anyway) I used the Adafruit ItsyBitsy M0 To get the ItsyBitsy working go to: ...

I designed this to provide additional switch controls for my Loxone home automation system.I needed additional switch controls at various places around my home (desk, kitchen island, etc), so I designed this switch case to house an ESP8266...

Other notes: To silence the hotend fan, one could use a separate power supply or an appropriate resistor to undervolt the fan instead of buying one of those expensive Noctua or Noiseblocker fans. I undervolted mine to around 6V with no problems (PLA...

If you go the LED route you will need some resistors to wire to the Lolin, but I didn't do that so I can not advise on what exactly you would need or how to program it. The inside of the back box is not the cleanest, the floor is raised up just a...

You need to modify the fan with a 2N2222 transistor and a resistor though. If you don't want to use a fan but some other cooling, there is enough headspace for most cooling systems. Mine runs passively and rarely triggers the fan. Nevertheless,...

This is simply moving a 0 Ohm resistor from the 10Hz spot to 80Hz. This will effectively change the speed to be quick enough to be useful for a brake. For the PCB Sleeve, I wired the Pin headers on sideways so it poked out of one end and then wired...
