This not only reduces the energy dissipation, effectively lowering the operating temperature of the fixture, but also prevents AC over-voltage and short circuit loading making this fixture virtually maintenance free. Because the electronic driver...

 Now I am using a 555 based circuit to generate the required pulses (1-2 ms every 20ms).  Once the ESC initialises, just turn it up and make noise.  On my ESC I have to start with the minimum setting (effectively the throttle channel...

If after pressing a button your controller stops responding for a short time and disappears from the list of controllers in the application window, then you connected one of the buttons to +5V and by pressing this button you make a short circuit. In...

 Replace the colored filament with clear PLA and finish the print.Material:  PLA (colored for the top layer, clear for the walls)Quality:  .12mmTemp:  200°CBed:   67°CPrint Speed:  50mm/s, first layer at...

Easiest is to use 12V directly but a phone power bank with a boost circuit should be fine too. Mine draws 1.2A from a USB supply when powering a MT3608 boost converter (MT3608 can supply an output current of 2A and runs warmish when powering my Ozone...

I never found a need for using the button so none of that circuit was used. If you build it on perf board just connect pin 1(Reset) to 3V through a 10K resistor. The connections labeled TP6 and JP2 can be left off the board. The power connections are...

Very simple switch circuit.Take the 2 Red wires from the 2 LED connectors, twist them together and then insert them into the positive (+) terminal of the DC power connector. Make sure you have about 1/4 inch bare wire stripped away before you do...

Yes once built propetly but i strongly recommend covering the circuits with nail varnish or a dedicated protective product, put the battery in a small waterbaloons and keep a piece of sponge inside the hull. Water protection spray for electronics ...

Now I am mostly working on the lower arm (which will probably be nothing like the original frame, less detailed, more practical to strap on some armor and house the servos and circuit board to manage the hand movement). ALPHA/Preview 0.4 11/25/2015...

So no risk there :-). It requires these pieces: MQ2 Smoke Sensor...

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...

For 1 rotation of the display, it should count from 0 to 5 twice.) If you haven't already, cut the switch off of each endstop circuit board and solder leads to the C and NO pins. Slip the endstop switch through the rectangular cutout above the motor....

Two holes in the edge of the circuit board should line up with holes in the outside of the enclosure. You can affix the board using short M3 screws.Attach the motor to the flat housing piece and the stand / bearing housing with 2 30mm M3 screws. Line...

Don't bother trying to vary the speed in your slicer program, the fan circuit in the FFCP is on/off only. The simplest way to obtain variable fan speed is by installing a hardware PWM controller. There are also some custom Sailfish firmware builds...

But please do not measure the length of your 18650 battery with a metallic calliper as this will lead to a short circuit with potentially dramatic results (e.g. welding of the calliper to the battery terminals followed by explosion and fire).Do not...

This trick circuit was chosen because of the construction, since the first LED is mounted separately (on top) anyway. The remaining 4 LEDs can be glued as a band around the "lighthouse".The diameter of the "lighthouse" is designed so that the...

The D-pad Center Spire gets superglued to the circuit board between the D-pad buttons to give the pad something to rock on for that classic feel. Front center is a flush button that will return you to the main menu in Retropie from the game. This...

It is possible to connect the external power of the battery with a voltage of no more than 5B. The circuit board has standard Lego holes for attaching the board to the Lego-designer's details. Versatility makes this board an indispensable driver for...

I used the arduino relay schematic here: http://www.instructables.com/id/Arduino-Relay-Circuit/ - minus the indicating LED. PIR – This lid will hold one PIR unit, and nothing else will fit into the box. You will need a couple of drops of super glue...

The main function of the fuse is to protect the module in scenarios like short circuit on the strip side. I strongly advise against running the module close to 10A. Keep in mind that even the JST SM connector, that addressable LED strips use, is...

Servo driven nozzle wiper arm.Servo HiTec HS311 on RAMPS 1.4Electrical Spikes maybe an issue: Servomotor protection circuit test. A diode may fix this issue https://youtu.be/IierWEZ0SKU via @YouTubeNozzle cleaner wiper improved. Servo to move 3D...

You can also search “Brass Pillar Female Threaded Spacer Nuts Standoff Nuts for Circuit Board in size M3 x30mm to find them.And two M3 screws, I like cap screws. one needs to be 12mm and the other 8mm I think. The heads are usually 5.5mm diameter and...

 Its why the sled has cut outs for a circuit and a small 20x40mm speaker.  Its also why there is space for a tactile switch in the grip.  I haven't finalised that version yet though. ... The Power Cell interior will be replaced with a different part to...

----------------------------------------------------- This is a blower assembly to dry / air out the counterlungs and loop of my JJ-CCR Closed Circuit Rebreather after post-dive cleaning. I have designed this to be reasonably modular. The blower...

Please do not plug in - here the risk of short circuit is too high. 1 x E14 LED bulb 3-5 W. For more than 5 W, please be sure to drain the lid or use an appropriately high lithophane image. It may otherwise become too warm!</li> <li>1 x connection...

Use this circuit if the leds 'glitch' Use electrician tape to isolate the logic level shifter. Final Step, Mount the Nanoleafs Make sure you flash the software first and test the leafs. If glitches occur use a logic-level converter. If there are...

I originally used 8mm screws to attach the breakout board to the circuit board mount and I am now using 12mm screws to mount this riser. Installing Customise the riser or use one of the provided STLs and print it Attach the FFC extension PCB with...

The circuit ensures that the windvane directly controls the yaw motor. 9. Parts See dutch text below. -Square carbon rod 13 mm -Linear motor -Relay with remote control -Needle pivot bearing -Clutch -Bearings -Spray motor -Generator...

Electronics The main controller is an Arduino Micro Pro together with a standard Hitec servo circuit board extracted from an old servo, but used with a high-end DC-motor with gearbox. I will post a link here to a suitable motor soon, so check back...
