  • SD Card Slot for Raspberry Pi Replacement (RPISD)
    You can use these card slots to replace broken SD slots on your Raspberry Pi.

    Technique:
    • Use side-cutters to cut all the pins on the old socket
    • Use a soldering iron to remove what's left of the pins to ensure each pad is clean
    • Use a sharp knife to cut off the 2 mounting lugs on the back of the new socket
    • Plase the new socket very carefully so the front of the socket is fractionally behind the edge of the Raspberry Pi board and central between the two front solder pads (there will be a small gap to these mounting pads
    • Solder one front mounting pad and check the SD socket is still positioned correctly
    • Solder the remainder of the pins and mounting positions as shown in the photos

  • Diffused 5mm Fast Flashing RGB LED - Pack of 2 (LEDFKSHF)
    These are very interesting 5mm diffused RGB LEDs - instead of having 4 pins to control 3 LEDs, they have only two leads - power and ground. When powered, the LEDs perform a flashing effect with all the colours. See the video below for the timing and look. There is no way to change the 'program' or rate as it's burned into a little chip that is inside the LED itself. We also have a version that's a 'slow fading' RGB colour cycle.

    They're fairly bright LEDs, we guess its something around 1000 mcd total. They do diffuse nicely so you can the color changing from any angle. The forward voltage of the whole LED is about 3.4VDC but you can drive them from a lithium coin cell like a CR2032 and they'll just be a little dimmer. We don't have a datasheet showing the current draw over different voltages and colors but at the 'rated' 3.4V its approx 20mA and at 3.0V its approx 10mA.

    Comes in a pack of 2 LEDs. Although the LEDs are all the same shape and have the same basic program, due to manufacturing variables they will not sync together - they'll slowly drift in and out of sync

  • 2-Pin Mini Slim Tact Switch - Pack of 4 (TACTSLIM)
    Pack of 4 slim tactile push button switches. Suitable for breadboards or use with the Pi TFT Screen

    Slim clicky momentary switches are standard input "buttons" on electronic projects. These are half the width of classic 6mm tactile switches so they line up better on a breadboard, just plug them into every-other row. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The two pins are normally open (disconnected) and when the button is pressed they are momentarily closed.
