  • Wiring the matrix (columns)

  • Now, solder 8 wires between C'x and G"x. Calculate the appropriate current limiting resistors values and have them handy (do the calcs and buy them beforehand). Solder the resistors on the borad and use wires to solder the PMOS drains (D'0, ..., D'7)...
  • Top wiring 3: Ground connections

  • Top half of case. There are two ground wires on the LiPo charger. Stretch one over to the large circular area of the keyfob. (See photograph in Step 14.) Cut to length, strip it and solder it to the circular area (in common with the black wire of...
  • High side drivers (current sources)

  • Repeat 8 times: take a BS250P PMOS and solder the S, G and D pins to the board (S to the Vcc bus) and a 10K resistor between the G and the S (or the Vcc bus). Let's label the Gs and Ds (G'0, D'0), ..., (G'7, D'7), respectively. Take a BS170 NMOS and...
  • Third Eye for The Blind

  • Making the ModulesFirst cut the pref board in 5 X 3 cm dimension and solder the female headers for the arduino to the board.Then solder the buzzer.Then connect the vibrating motor using the glue gun and solder wires to it.Then connect the LED.Then connect...
  • Prepare the Tools

  • Be sure to have the following tools ready: 3D printer with 200mm x 200mm bedSoldering iron & solderSmall side cuttersHot glue gunAllen wrenchesDupont crimper kit (optional but recommended)
  • Prepare the cable

  • Add a solder blob on each pin of the DIN-13 connector Solder the wires following the color code/pinout on the schematics. Start from the lower and use heat shrink tubing on each wire. Solder the cable shield to the connector shell taking care to not...
  • Assembling the PCB

  • After receiving the board from the PCB fab house, you have to solder the components. For Soldering, you will need a decent Soldering Iron, Solder, Nipper. First I cut the straight male and female headers pin for ESP32 Board, TP4056, BME280, and jumper...
  • Build for Cooling

  • There's a free license version of Eagle Cad for viewing/printing/exporting gerbers etc. Otherwise in the gallery you'll see a schematic and a layout guide.The FETs and the Snubber Schottky are laid out along the edge of the PCB for direct mounting to...
