5v Computer Buzzer (as a speaker) NPN Transistor BC548 with either a 1k or a 2.2k resistor (sorry I forgot witch one) as a simple 5v amplifier. I made tons of settings, and the ability to save them as presets in NVS. Because it uses soooo much...

Just choose a suitable resistor to add to the LED, because this device uses a power supply of 9 volts or more. Step 22: All that remains to be done is to cut the humidification filter paper into a suitable size, set it in place, and use any...

Just the plain flexible PCB with the LEDs and resistors soldered on. I used a 60 pixel/mm strip and ended up using 57 LEDs in total. Printing: You need to print a the socket, the lid and four ring pieces. One of the ring segments has an opening for...

These are connected to GPIO pins on your Raspberry Pi (don't forget the appropriate current-limiting resistor). These are only there for ‘status’ notification and to provide a natural cue to your eyes as to where the camera is - you can't see it that...

This can be found easily in AliExpress and other online stores.-shunt resistor 1 ohm 5 watt. This will get a bit warm so get a good metalfilm one. You can also go higher, but code will be need a bit a of change as the analog read this is used to get...

Heating the contacts of the resistor solved the problem in my case. Insert theButton Tops into theFront Panel and mount theButton Housings. Same goes for the<em>Side Button Top</em>s.</p> <p>After wiring the buttons bend the pins a bit. Otherwise,...

The electronics involved in the controllers, cars and digital track parts are quite simple and easy to source, like cheap arduinos, resistors, diodes, leds, RGB digital leds, pots and a few more things. I have made the car and "lane-changers" work...

Screw the cap on first with the wire passing straight through the cap, thread it out the side when it has been screwed down all the way, it lines up correctly when screwed down all the way. Candidate for the plunger Notch the washer Solder wire in...

The steps will be similar for other operating systems. Remember to select 'Arduino Nano' under 'Tools &gt; Board'. Assembly Please use this diagram as a reference: Note: It should not be necessary to use a resistor or capacitor, however, they may be...

The resistors are all 1/8 Watt. The gerber files for having the boards manufactured will be on the Github for either the Picaxe ar Attiny board.You will need to zip them up to send them to the pcb manufacturer. You can also open the project in...

To emulate this, I connected a 42 Ω Resistor in series to the ground pins of the switches. After the ground pins have been soldered, also the positive sides of the switches have been soldered according to the schematic. In order to connect the...

You need a resistor on the positive side of that LED!” Well, I thought so too, but then I forget to put the resistor in and everything worked fine. However, if it would make you feel better, feel free to put a resistor in the line somewhere. You make...

Just the plain flexible PCB with the LEDs and resistors soldered on. I used a 60 pixel/mm LED strip and ended up using 120 LEDs (60/60) in total for the big version and 70 LEDs (35/35) for the smaller version. Printing: You need to print a the...

Once you are sure there are no issues, you can remove the Thru Shaft and PCBs from the assembly and move on to assembling them.After cleaning up the PCBs (including drilling out the 1mm thru holes for the components), begin assembling the Powerboard...

It serves no purpose, and probably insulates the strips, causing higher temperatures. I would avoid strips with resistors that are right at the edge. It might interfere with the track the strip sits in.</p> <p>The tracks for the strips are 11mm wide...

Just the plain flexible PCB with the LEDs and resistors soldered on. I used a 60 pixel/mm strip and ended up using 118 LEDs (58/60) in total for the big version and 70 LEDs (34/36) for the smaller version. You can reduce the number of LEDs for the...

I compensated for this by replacing the surface mount resistors on the LED strip with ones roughly three times their value. This made the LED strips run much cooler and only reduced the perceived brightness by a bit.</p><p>Since not everyone is...

Added some screencaps as they may come in handy if anyone ever builds on :) added electronics to trigger the plasma cutter, I used a TLP222G-2 opto mosfet with a series 2.2k resistor and 3mm LED, attached it to the heatbed mosfet output (D10) on the...

The inner strip might need to be opened and realigned.Led assembly, top channel does not attach to the top, but the base walls.The led data channels should probably have a resistor in series to protect the led's. Places like Adafruit and Sparkfun...

But even if you’re sticking to low-temperature 3D printing materials like PLA, it’s wise to ensure that your heated bed isn’t overpowering your motherboard The heatbed controller included on the Motherboard has two disavantages: fisrt: it's on board...

Once flashed, I usually do a whole batch, you can OTA.If using a PWM-controlled light strip (I will come up with an example soon), you will need a NPN-transistor, with left pin (metal to the back) connectd to D6/GPIO12 including a 1K resistor, GND of...

I made a small Power Hub which distributed the 12v on 4 outputs (1 for the mount, 1 for possible heating resistors, 1 for the focuser and 1 additional). In this hub I added a 12v> 5V regulator which powers the usb hub. The main power comes from a...
