• Glue aluminum foil to the main and secondary reflectors, then use an LED in the waveguide to make a flashlight. • Glue aluminum foil to the main and secondary reflectors, stick a coil of wire in the waveguide, and use it as a radio receiver. • Glue...

For the blade, I employed a fluorescent light tube guard that I sanded down to enhance its luminosity and lightly painted it red (a detail you can skip since the LED on the toy is already red). The design boasts a snug fit, necessitating some...

Remaining time is conveyed by a NeoPixel ring dropping an LED every 1m30s. A vibrating motor provides tactile feedback to each button press and adds an audible cue when the 25 minutes are complete. If something comes to mind during your 25min Focus,...

... the HEPA side, just like my Phillips air cleaner. I guess it's this way to avoid possible carbon dust. Todo/Ideas: - Power/control from RAMBO - Led lights - 24V PTC Heater to heat the build chamber, controlled from RAMBO - Gas and particle sensors

Pay attention to the physical pinout of the LM555 IC per datasheets and polarity of LEDs. 3. Solder the 4-pin USB cable with colors as indicated in the schematic. 4. Test the panel by applying 12VDC to the Red cable and Ground from your PSU to the...

For the LED of the power button, I added a 10k resistor so that it does not shine too brightly, otherwise the extra shine interferes. And also connected the LED to a constant glow so as not to forget to disconnect the power cable when moving the...

These are just the best bang for the buck I have found: ###**Net Pots and Cloning Collars** >xGarden Neoprene Clone Collars - 120 Pack Cloning Collars, 2" Inch, Multi-Color - DIY Foam Cloner Inserts for Net Pots, Hydroponics, Aeroponics...

Besides being a voltmeter with data logging, it could answer questions like "how much voltage falls on the LED at 10mA current?" or "is this an IR LED or what?" by showing the diode's voltage drop as a function of current at 5 points. It has a...

this is how this robot came to life combining to great platforms and adding more articulations to create a new member of the Otto family.This a remix of the original Otto robot with the idea of using a micro:bit board instead of Arduino, it has 8...

Seriously, there's just no reason to not use an LED lamp these days anyway. Assembling the Shade This is the fun part! Print a number of the Penrose tiles and start connecting them to form the pattern shown on the provided line-drawing. Start from...

The process of adaptation presupposes that practical aspects of printing the model using the DLP/SLA/LCD technology are taken into account, and the model's scale and cutting are chosen to ensure an optimum result of printing.3D PRINTING...

It's bright enough to be a bit annoying - I might paint over that LED with nail polish. # Printing and mounting Print `Mount.stl` and `Filler.stl` - `Mount.stl` needs supports. You might want to attach the jumper cables before putting the chip...

One of the first things I added to my Prusa i3 was a Raspberry Pi 3B+ running the excellent OctoPrint platform as this provides WiFi remote control and webcam monitoring of the print – a must for any 3d printer. However, I wanted a fully integrated...

Since many of my friends own the 18V Makita battery system I thought of a practical Christmas present for them.I got the idea for the basic platform from user "bitplusatoms" with his design "Makita Battery Mount"...

(Helps to have a long allen wrench.) 11) Screw in the E12 LED bulb. Supports are only needed for the part "Base.stl". I designed this in Fusion360 and have included the .f3d file and a .obj file if you need to modify. This could be used...

Step 10- Insert the LED light and position it so that when you rotate the ring it should both activate the core and lights at the same time. and that's it, play around with the colors make your own custom color scheme, Hopefully, yall are able...

It contains one LED (to show the charging status) and a micro USB connector. The “magic” behind the charger is that it simply connects the minus terminal of the USB cable to the two outer spring contact and the plus cable is connected to the middle...

You can see my buzzer and connector in the pictures above.LED Matrix: I used the Open-Smart 16x8 I2C LED Matrix (AliExpress). I adjusted the original holder slightly so it would hold this module very snug. When using this I2C module, connect SDA to...

Similar to LED lamps, excimer lamps provide “instant-on” startup, and do not require a warmup period; excimer lamps are at 100% peak output when switched on. Most lamp technologies that do product UVC use mercury in the manufacturing process. Excimer...
