1 PCB Housing
- It is starting to look a lot like… we need a housing for our PCB board.
- We can design this on Solidworks. As well as practising our skills on Solidworks we can check whether the parts will fit together.
- Lots of the ideas are Xmas themed but you can make whatever you like but are limited in material to 100mm X 100mm.
Part 1 - Inspiration, Design movements and Sketching
- First of all we are going to do some research into 'Design movements'.
- Design movements...
- Once you have found an idea, you can sketch it out on paper with a pencil and start thinking about what criteria our case/product is going to meet.
- I've included four sketches for ideas. A good sketch should include:
- materials, parts, dimensions (in mm), how it fits together, what the product should be do and some criteria.
- Some important dimension are:
- The maximum size is 80 X 80 X 100mm (length, width, height)
- The battery is 25 X 18 X 55mm
- The PCB is 35 X 30 X 10mm
- Ideas for criteria are:
- Waterproof, durable, fit three 5mm LEDs (6.8mm diameter/3.4mm radius holes), respond to changes in light, has an input or push-to-make switch, runs off 9V, is programmable, fun, educational, what the program does, functional i.e. holds a phone etc.
- Things to remember to include when designing:
- LEDs X 3
- LDR X 1
- PTM switch X 1
- Toggle switch X 1 (if you include this)
- Wiring to all the components, including the battery
- How will the battery be replaced?
- Types of joints you will use (finger joints, screws, etc)
- Do the dimensions match the criteria. Remember the material is 3mm thick, so you will need to compensate for this.
- Sketch one - 'Traffic Lights'
- Sketch two - 'Snowman'
- Sketch three - 'Wintry Scene'
- Sketch four - 'Elephant phone holder'
Upload a photo of your sketch, with some criteria, to the badge on Bourne to learn.
