Prices / suppliers based on current availability in NL (January 2016)
|GoPiGo base kit||75,95||SOS Solutions||currently on backorder|
|8x AA battery (rechargeable)||7,98||IKEA|
|Raspberry Pi B+||29,95||Kiwi Electronics||*see note 1|
|8GB SD card with NOOBS||8,95||SOS Solutions|
|WiFi dongle 300Mbps||11,77||Mijn Hebbeding.nl||*see note 2|
Note 1: I already owned this B+ before the 3B existed… if I were choosing today, I would rather take the beefy quad-core for those 15 extra euros, and then forget about the WiFi dongle…
Note 2: This particular link is only included to specify the one that I have (bought somewhere else for less, but that is not available anymore). For the all-new RPi 3, a WiFi dongle is no longer needed.
(you will also need:
- a LAN cable to set up the RPi WiFi
- a charger for the batteries
- a 5V / 2A microUSB adapter to power the RPi while developing…
…I’m not counting those as parts or cost for the robot since your household probably has these items anyway, and they are not ‘used up’)
|Grove Ultrasonic Ranger||19,95||SOS Solutions||*see note 3|
|Raspberry Pi Camera||24,95||Kiwi Electronics|
|Pan/tilt mechanism||4,45||Hobby Electronica|
|2x TowerPro SG-90 micro servo||6,70||Hobby Electronica|
|WS2801 RGB LEDs (7 pcs cut from a strip)||4,36||Kiwi Electronics||*see note 4|
|Adafruit “absolute orientation sensor” BNO055 breakout||37,95||Kiwi Electronics|
Note 3: In retrospect, this feels like a rip-off when I see generic equivalents for a few euros… the Grove branding does something to the margins I guess.
Note 4: This can only be bought per unit of 1m (32 pcs), the cost is calculated for 7/32th part of that.
|Pin header 2×13 (for breaking out the GPIO)||1,00||Kiwi Electronics|
|Female/female jumpers on a ribbon (to connect peripherals)||3,00||Kiwi Electronics||only half is used|
|Flex cable 30cm (for the RPi camera)||2,95||Kiwi Electronics|
|Wire (to connect bits of LED strip)||neg||*see note 6|
|Heat shrink (protect custom connectors for servos & orientation sensor)||neg||Kiwi Electronics||*see note 6|
|Bits of male pin header (to create custom connector for servos)||neg||Kiwi Electronics||*see note 6|
|4x pingpong ball (to cover the LEDs)||?||these were a gift|
|Leftover bit of flexible drain pipe (bumper)||0,00||salvaged from trash|
|Sturdy plastic cutouts from toy wrappings (back shield)||0,00||salvaged from trash|
Note 6: Assumed availability for electronics geek, only little bits are used up, all the “neg” cost together probably amounts to less than half a euro.
- All the subtotals add up to a grand total of 239,91, excluding shipping.
- If you already had the RPi stuff lying about anyway (board + memory + wifi + camera), you can deduct ~75 euros from the total.
- If you order everything online and combine orders where possible, the shipping cost would amount to an extra ~20 euros.
