Bright ideas: wifi-enabled, neopixel bedroom clock

Vance joined the Hackspace just before Christmas and has wasted no time in completing his first project. In that time he has mastered use of the laser-cutter, got to grips with programming wifi-enabled ESP8266 chips, designed his first printed circuit board, had it made by a board-house, and brought it all together in this ingenious bedroom clock.

The time is represented with twelve radial segments of frosted acrylic that are lit in red, green and blue according to the positions of the hour, minute and second hands. As the hands pass each other they combine to illuminate the room with an ever-changing pattern of coloured light (see video below). What’s more, he has made all the CAD design files for the parts, the code, and the PCB design in a repository and written a blog post to document how he did it.

A brilliant project Vance –  great idea, great design, great finish, brought together at great speed. You’re making the rest of us look like amateurs!

Let it snow! Let it snow! Let it snow!

If we get a dusting of snow this year, there will be at least one person with a massive smile on his face. Stuart, one of our members and founder of NADHack – Newbury and District Hackspace – will be poised and ready to launch his ski-bike on an unsuspecting world.

No, nothing dangerous-looking about that

It started out life as a cheap aluminium-framed Reebok-branded full suspension bike.  All mechanical components were removed (some quite forcefully!) and the brake mountings, shifter mounting etc were ground off. The pedal shaft was replaced with an arrangement of steel angle which was ground into the footpeg shape and welded using the Kempi MIG welder.  The footpegs are exceedingly strong!

Reading Repair Cafe – this weekend

Reading Repair CaferLab is proud to be hosting Reading Repair Cafe this Sunday, January 24th, between 12:00 and 16:30.

So if you have something that’s broken, or some tools that need sharpening, bring them down to Unit C1, Weldale Street, Reading, RG1 7BX, where the volunteers will be only too pleased to help you.

There will be plenty of expertise in computers, electricals, mending clothes; the right tools to get things fixed; and some cakes and food for sale too!

This sofa’s made for walking

When you think of a hackspace, you think of many things – perhaps electronics, machining, open-source hardware – but shoe-making is not the first thing that springs to mind. Here at rLab we work to a broad, pretty much unbounded definition of the term, and if you’ve got a project that you want to do in our workshop – it doesn’t have to fit within a definition, that’s cool with us. Want to make a pair of boots from scratch from old sofas and bits of tyre? – errrm – OK!

So after weeks of leather harvesting, tyre stripping, experimentation, sewing and glueing, we are very proud to present this first pair of boots – made from scratch, in our workshop, from recycled material. Well done Tara – awesome work!

Casting aluminium wheels

Cast aluminium wheels

Last Friday we fired up the crucible and did some aluminium casting at rLab. Mostly  melting some scrap into ingots, but Andy also made this fantastic pair of wheel blanks using lost foam casting. He has since put together this great video that shows the full end-to-end process, including how he prepared the moulds – well worth a watch if you’re considering doing this yourself.

 

How long will the rain last?

Want to know how long the rain is going to last? Simple- pop out to the shed and build yourself a weather satellite antenna from the bits that you can find. [OK – there may be easier ways of finding out, but this looks far more fun!]

 

Circling above your head the US National Oceanic and Atmospheric Administration have satellites constantly broadcasting back data and pictures using APT on ~137MHz. There is nothing to stop you receiving these images yourself and, like Simon, you can build a ‘quadrifilar helicoidal’ antenna with some plumbing supplies and the help of this great online calculator.

Connected to the antenna were an RTL-SDR dongle and a computer running gpredict to track the satellite, gqrx to handle reception, and wxtoimg to do the APT image decoding.

Next up? Let’s add a SatNOGS ground station to roof of rLab!

Inter-Hackspace Robot Wars 2015

We are off to Newcastle-under-Lyme next weekend to compete in the 2015 Inter-Hackspace Robot Wars organised by the Potteries Hackspace. Aside from the home team, we’re also up against teams from Bromyard, Hitchin, and Birmingham.

Reading Hackpace's menacing entry for the Inter-Hackspace Robot Wars 2015

Reading Hackpace’s menacing entry for the Inter-Hackspace Robot Wars 2015

One of the most challenging aspects of the competition is staying within the 10kg weight limit. Once you’ve put motors, batteries and drivetrain onboard, there’s not a lot of scope for much else. Ours is based on a biscuit tin! It might not look strong, or particularly menacing, but perhaps our entry is not quite what it seems [mwahahaha].

We’ll report back in a couple of weeks with a fuller write-up and hopefully some video of our victorious entry.
