Hacky New Years/2023
Hacky New Years 2023 Plaque
Assembly Instructions
Included Parts
- 1x PCB Panel
- 1x 3x2 0.1" Pin Header
- 1x 3x1 0.1" Right Angle Pin Header
- 1x ATTINY25 MCU (pre-programed)
Through Hole Soldering
All surface mount components come presoldered to the PCB. Through hole soldering is required to complete assembly.
Separate 'CN-Tower-Resistor' PCB and Main PCB
Using your hands and a pliers, twist the PCB to break away the mouse-bites connecting the 'CN-Tower-Resistor' PCB and Main PCB.
Solder right angle header to 'CN-Tower-Resistor' PCB
- Make sure the plastic is on the side of the PCB with the white outline.
- The 3x2 programming header can be used to support the PCB while soldering right angle header. This allows the PCB to lay flat on a work surface and will not tip over when soldering.
Solder down ATTiny25 micro controller.
This should already be taped down to your PCB panel in the correct orientation, but verify the chip orientation matches that of the silkscreen.
Solder programming header to Main PCB (Optional)
Solder'CN-Tower-Resistor' PCB perpendicular to Main PCB
- A roll of Electrical Tape is about the correct height to aid in this next step.
- Place the Main PCB atop the electrical tape, with the 'CN-Tower-Resistor' PCB inserted below and supported by the work surface.
- Solder only the First pin right angle header! (the one closest to the viewer in the photo)
- Pickup the whole assemble.
- While reheating the solder joint of the first pin, adjusting the positioning of the 'CN-Tower-Resistor' PCB to be perpendicular over the LEDs on the Main PCB.
- Solder the remaining pins on the right angle header.
FAQ
- Q: How do we power the Plaque?
- A: Provide regulate 5V to labelled points on the programming header, either via the pin header if installed, or soldered directly to the vias if you choose to leave it off. Since ever hacker space is a bit different we left it as an exercise to those spaces.
