On Thursday 26th and Friday 27th, myself and an army of volunteers students from the Computer Science department at Queens University took part in delivering workshops for 250-300 Northern Irish schoolkids from across the province, as part of the BBC Make It Digital event.
The event was held at BBC Blackstaff studios in Belfast and ran from the 26th – 28th, although we were only doing Raspberry Pi workshops on the 26th – 27th.
So a while back I heard about the Motorola lapdock. It was designed for the Motorola Atrix phone, idea was it would slot in the back and could be used like a computer.
The idea never really took off so there are a number of people in the world sitting on large warehouses of these.
11.5 inch screen
Keyboard (usually has English and Hebrew characters)
Trackpad (isn’t great, would recommend USB mouse)
x2 USB ports via built in powered USB hub
4-6 hour battery life with the Raspberry Pi model B+
Battery status LEDs
Weights little over 1kg
Micro HDMI male port (for connecting to Raspberry Pi)
Micro USB male port (for connecting to Raspberry Pi)
Using with Raspberry Pi
With the correct cables, the lapdock is perfect for use with the Raspberry Pi, especially for use with a mobile classroom or one that needs to be packed away at the end of a lesson.
Setup is extremely quick, for Raspberry Pi 1 model B, you only need 2 cables. For Raspberry Pi 1 model B+ and Raspberry Pi 2 model B, you require an extra standard micro USB cable as the newer Raspberry Pis don’t support backpowering over USB.
The lapdock requires some pretty specialised/weird cables to use it. You require a male USB to female micro USB and a male HDMI to female micro HDMI cable.
The more complicated cable to hunt down is the HDMI cable. Best source I have found so far is here.
Where do I get a lapdock?
A good question. There are a number of sources you can buy them from. The most direct option is from Israel, where a charity is sitting it seems on a warehouse or 2 of them. A majority of UK sellers will have likely bought it directly from them and are just reselling it a bit higher. You have 2 options, buying in singles or in 6s.
Just a word of warning. Given you are ordering an item in from outside the EU, you may have to pay import taxes, especially if buying 6! I ended up with taxes and charges close to £95 when ordering in 6 recently.
They were still well worth it though!
So what do I think?
They are awesome! We can take the 7 we have and have them set up in a matter of minutes, given it is so few cables. The inbuilt battery is extremely useful for workshops where we don’t want to set up a mains network across the room. They are extremely well built and feel solid. They are also great to sling in a bag or suitcase where you know you will need a Raspberry Pi setup. A perfect example is I quite easily brought over 2 to the Raspberry Pi 3rd Birthday celebrations in Cambridge at the weekend with no issue due to them being extremely thin and light.
The keyboard is fine to use, although I sometimes find the spacebar doesn’t register. The keyboard though is completely usable and I have had very few complains from students about it. The trackpad isn’t great, so I would recommend a cheap USB mouse to go with it if using it extensively.
I don’t know anything out there that could beat it for the price and ease of use combined! Including cables, they work out about £75 each if you get hit by import taxes and ordered in 6s. The screen is extremely clear, the build quality is excellent and the battery is a much welcomed added bonus.
If you need a solution for your Raspberry Pi that you can throw into a bag for Raspberry Jams etc, this might just be it.
