BBC Micro:bit Toothbrush Timer

A few months back I bought a BBC Micro:bit at the Science Centre in Glasgow and it's been fun building apps with the single board device. I thought I'd write a blog entry about the latest project which will be a more permanent installation in our bathroom.

A toothbrush timer!

Kitronik sell an add on board which provides power from a coin cell battery and a piezo buzzer called a Mi:power, they also sell a Mi:power case which is designed to fit around a Micro:bit fitted with the Mi:power. This assembly combined with some code offers a neat toothbrushing timer. By using the display on the front we provide a short countdown - with a little tune through the buzzer. The program show 6 areas of the mouth to brush each for 20 seconds before showing a toothy grin and a finishing tune. Each time the area of the mouth changes it plays a 'level up' style jingle.

Howto: Ubuntu 8.10, Dell 5530, 3G/WWan and GPS

There is an updated howto on the Dell 5530 using my own python based monitoring tool at http://blog.bjw.me.uk/2009/03/dell-5530ericsson-f3507g-on-linux.html Introduction Here is a Howto document for getting the Dell 5530 wwan card working along with the onboard GPS under Ubuntu 8.10. This card does not work conveniently with the bundled Network Manager software, but replacing NetworkManager with other utilities will give the ability to get online using a pretty GUI and not have to resort to using wvdial and the command line... It should also work with the Ericsson f3507g as I believe the Dell 5530 is a rebadged version of this module. Check Hardware First you need to check the modem is detected correctly. On my computer, the modem is detected out of the box by the cdc_acm module and exposes three serial ports (/dev/ttyACM[0,1,2]) for communication. Check by running: dmesg | grep ACM Mine shows the following: [ 34.385302] cdc_acm 1-6:1.1: ttyACM0: USB ACM device [ ...

Linn DS Alarm Function

Update 2014 - An alternative to this is available on GitHub which uses Node.js and should be cross platform. Linn DS Playlist and Alarm Server Switching the radio on in the kitchen in the morning is a low priority amongst setting table, pouring cereals, carrying children, etc. The Sonos has an alarm clock facility which allows you to switch on the radio at a set time avoiding hassle of starting a controller. When I upgraded to my Linn Sneaky DS, I no longer had this function, though the remote control made it easy if I forgot to take my phone downstairs with me. Last week I decided to figure it out. I have a Linux machine which runs Ubuntu and runs all the media servers, backups and network shares. I decided to investigate how to control my DS from the command line. Conveniently, the DS can be controlled via a web api, so after reading the docs and a few examples I was able to switch off and on and change source via Postman (Chrome REST client). I then set about writing...

Howto: Node Red Subflow for Hue Bulbs

When writing some flows for Node-RED controlling my Philips Hue bulbs; I wanted to read from a bulb do some work then write that same colour back to the bulb. When you perform a GET on a bulb, you get all of the information, whilst good this means it is a bit more inconvenient to PUT that back into a bulb as that API has a slightly different resource shape where the colour mode is determined by which values are submitted. After using a group of nodes in one flow which did exactly this, I needed the same block in another flow. So I created a sub flow by selected those nodes, clicking the hamburger menu in the top right and choosing 'Subflows > Selection to Subflow'. This replaces the selected nodes with a single node which you can edit in a 'subflows' menu group in the left pane. Download this selection and make your own subflow: https://dl.dropboxusercontent.com/u/174818/HueInputToOutput.json?dl=1
