Short circuiting lithium batteries can lead to combustion and smoke inhalation . We offer and imply no such warranty to this product . We hold no liability to death , fire , shortage of life , damage to structure , damage to property , etc . It is...

You should know how to handle Arduino Software and build electronic circuits!!! I myself am not an expert, so please doublecheck and let me know if i made any mistakes, so others can profit from it too!!! I do not take responsibility for any...

I build such a box to hold a small outboard circuit board for connection to extra things (in my case relays). V5 changes: Much better bezel that blocks all extraneous light from the display and frames the active part tightly. Also, this version is...

Wires from the battery box and motor were soldered to the on/off switch, completing the circuit. When turned on, the LED light on the switch lit up, and the wheel began spinning at approximately 5000 RPM. After everything was hooked up, the lid could...

Added images of the power supply circuit. Don't forget to come back for the full schematic soon! 9:29 pm, January 26th (Australia Day) Had some great news this morning - after re-printing the entire unit in 100% PLA, it turned out looking...

Generic pushbutton A bunch of wires See the breadboard picture for my circuit. I'm monitoring the battery voltage and flashing a warning, then shutting down if the battery gets too low. I also destroyed the power LEDs on both the Arduino and the...

  Edit 02/12/2021I have added a modification to the preamp box that allows it to hold a 9V battery.It is an alternative to the battery-free cover which is still valid for those who use a different power supply to be supplied through the connector...

Light controller box designed for exposure to photosensitive circuit boardThis is a remake of ThechBuilder PCB exposure box and the EleLab systems base module.This project consist of 3 parts:   - The Controller in EleLab style; ...

Pull the original MSFFB2 joystick grip off, cut the wires and pulled them through the base of the joystick and removed the wires along with the electrical connector from the circuit board. (NOTE: doing this will mean that the force feeback motors and...

This is the opposite to how this circuit is normally created, if the magnet was the other way round then output from the sensor rises and the normal comparitor setup would work.So what's for the furture of this project?For the filament diameter...

you can use one of these in place of one of the USB power boards if you are powering a bed heater that draws more than the Duet's 18A circuit can provide: http://amzn.to/2ozFxFg Lugs for two 5-pin Wago connectors (221-415) to be used as terminal...

They have over and under voltage protection, Surge, short circuit, overheat and overload protections as well as a fuse on the mains connections. These supplies run cool and quiet with a nice big fan. They can provide 12v and 5v, perfect for...

https://www.thingiverse.com/thing:1680291 or I choose to purchase onehttps://www.adafruit.com/product/905 Arcylic sheet (for mounting the circuit boards) Available in hardware stores, Lowes, Home Depot, Etc... M2.5 or M3 x 6mm Standoffs I found...

As any electronic hobbyist, I always need some enclosures to protect my circuits, and of course make them more user friendly. More over, with the news mini/micro/nano boards, like Arduino, Raspberry/Banana/Orange pies and so on, enclosures are more...

My suggestions is a helmet mounted IR light as they’re fairly cheap and extremely bright and require no wiring additional circuits i also have a sensor cap which fits the runcam pheonix and night eagle 3 sensor caps from other VPNVG lites are not...

Use female connectors on the constant current source to prevent short circuits. If no cramping equipment is at hand solder the joints.Prepare the wall base (file in “modern version”) by gluing the constant current driver and the female connectors in...

Running the current through the circuit board for 300 lights will cause the board to catch on fire in your living room don't ask me how I know this. ...Also be careful not to turn the brightness (and current draw) higher than the rated current for your...

I use clear nail polish to coat the circuit boards and connectors. Use a lot of glue/silicon around the gap between the camera and the battery box. After making sure the PIR sensor was set up i plugged the PIR sensor holes with silicon. The only...

The electromagnets are arranged in diagonal pairs, which are wired in series to provide a total of two coil circuits for the motor. The motor has a native resolution of 4 steps per revolution in the full-step mode. This low-resolution stepper motor...

Arduino Basic Code /*Wire length measurerThe circuit:* hall effect switch output attached to pin 2This code was based on the Arduino edge detection basic example script, and was hacked together by David Hartkop. It is in the public domain.*/ ...

You can build the circuit yourself or use one similar: KY-003 Hall Effect Magnetic Sensor. Don't use an analog Hall sensor - it requires additional circuitry. Refer to the manufacturer's documentation for details. Instead of ball bearings, this...

I put the LDR and LED on the same circuit so they can both be turned on with the same pin. I used some digital pins for power since the Pro Micro doesn't have a lot of 5V power outputs. I added a button for manual activation but mainly used it during...

I'd recommend removing any metal jewellery whilst building the circuits. Designed entirely in FreeCAD, I can post up the source files if anybody is interested (typing this+BOM has taken forever!). Also, as I post this, I've only just finished hooking...

As for the circuit board mounting holes I just hand tap them as needed depending on the controller used.Hardware:In addition to the M3 and M4 heatset inserts you'll need:1: 5mm dia x 50mm length of brass rod; I prefer brass because it's easy to...

I've attached a circuit that I use that allows the sensor to be powered with a higher voltage such as 12 - 24 V and lowers the output signal to 0-5 V for the input to the controller. It uses a blocking diode. When the sensor output is 12-24 V, the...

... code in RepRap Firmware to detect a power down moving the motors to the correct position ready for power up. The Duet WiFi has two power monitor circuits on board but it doesn't matter because the machine will run an auto levelling at start up.

The electrical contacts of the battery are protected from short circuits and dirt. The battery also has a fixed location and can always be found quickly. The empty battery also has its place immediately and does not disappear into a trouser...

The circuit diagram is in the list of photos (update March 2nd 2023: I found it again, yay!): this is as seen from the TOP. I made some small changes in the project source code and committed these to this forked repository:...

You yourself are responsible for what you are doing with this information.Never: make a short circuit on a battery!charge a single cell with a voltage greater than 4.2V DC!miss battery and connection polarity!over discharge, which is only...
