Saturday 17th October

removing the bad apples production line
  • some laser cutting of model railway bits whilst the machine was available.
  • Working on a new CNC.
  • Chopped up apples - probably 80kg?
  • pressed apples.
  • Drank juice: Children loved it!
  • Put ~ 40 litres of apple juice to ferment - two approaches, the first promoted by Andreas is using the natural yeast of the apple skin and very little else, the second backed by Jon is using a bought yeast, with a few chemical improvers - the competition will take until at least Christmas to find a winner.
  • The home brewing kit is all currently in use for Cider production, however if you are thinking of becoming a home brewer in the Richmond or Kingston area, but have been put off by the capital expenditure for the paraphernalia required, we have a set that will be available at Little House for you to try your hand (once the current production is bottled off).
  • Tried to explain the significance of 'fork handles' to Paul - he understands Ronnie Corbets Blackberry problems
  • Discovered that we don't have an outside tap despite the fact we have two long hose reels! Found tap adaptors for inside taps, and then discovered they don't fit the taps in Little House. Improvised.
  • Pressure washed the press and crusher for storage until next year.
  • Discovered that we in fact have two mops - and applied them to the floor of the kitchen and toilet which had become 'damp' during the 'cleaning'.
  • Modified the tap/hose adaptor to fit the taps in little house kitchen, and laser cut a replacement washer (with a further spare left in the 'o-rings' box).
  • Sink trap in toilet leaks quite badly - we need a volunteer plumber.
  • Hoovered the floor.
  • Paul attempted repair of loose slate on corner of Little House - we might need some araldite/epoxy glue.
  • Carl investigated the contents of the loft storage space.
  • Worked on logo for RML - plan to make a 'passport' stamp.
  • Put up a butterfly house.
  • Bus countdown working 3 days in a row! Ham Library friends notified.

Tuesday 13th October

Library Project version 1 complete
Busy Day!
A quick view of the future
  • Children designing their own helicopter/plane with Katrina and Ian
  • Laser cutting ahead some wood flooring crafty!
  • Picked up fermenting bucket for you know what. First attempt at cleaning was moderately successful. (re)Discovered how hot water in kitchen works.
  • Andres moved the broken hdmi screen outside.
  • Wood cutting with a radial saw outside
  • Harriet working on her self-designed cnc machine.
  • Screen taken inside and Jon opened the back cover to expose electronics, no obvious dry joints. Set the back cover on again an it is fixed!
  • Andres helped with a live instalation of Damn Small Linux (50Mb!)
  • More help with an HP printer.
  • Some arduino tutorials done in a corner
  • Some tutorials about resistance and experiments with resistors .
  • Rechargeable drill did in fact take a charge, BUT switch faulty - only screws in, not out. When dismantled switch is unusual design, and batteries in poor condition, the switch alone might be worth fixing, but not if it needs new batteries as well - propose dismantle for the motor/gearbox. We still need cordless drill/driver. There is a larger bosch drill that only has dead battery.
  • Bus countdown complete only test for long term use. (Update: works for 48hrs in a row).
  • More on robot building
  • Attendance tonight = 18

Tuesday 6th October

  • Laser etching wood
  • 3D printing Apple Watch charger station
  • HP Laptop partly disassembled and fan intakes cleaned as was overheating
  • Electronic conference badge from EMF Camp 2014 (Link) replaced surface mount charge controller

  • switching LED on via internet using arduino
  • CNC router emergency stop switch
  • More shelving put up - Jon is still looking for shelves and twin slot system parts, but is running out of walls.
  • Extra workstation between kitchen and cloakroom was commissioned - a lot tidier than it was.
  • Ian cd rom on laptop
  • We were visited by a number of Kingston University students to have a look at what we are up to - see you again soon?
  • Investigate donated electric screwdriver reported as 'not charging' - requires further thought next week.
  • re-advertised computer desk on freecycle - its now a bit in the way...
  • HUG apple collection/pressing and juice/cider making scheduled for next Saturday.
  • Paul G (Founder) visited
  • Attendance tonight = 17

Wednesday 30th September

  • We later visited Littlehouse
  • Attendance tonight = 9

Tuesday 29th September

  • The robot car got some front wheels and ran a great distance through the car park. Something eventually became disconnected and the car ran around in circles. The robot car needs a name, but nothing has yet been decided.
  • Jon had brought 4 eight-foot shelves, and heroically replaced the shelves on the west wall. The east wall shelves can now be put up, but that's for another week. Jon's also bought more uprights on Ebay that should complete the east wall, but we could still do with some 305mm/1ft wide shelves of 4-5ft length.
  • We still have a good condition surplus computer table 1400x800mm available for free if anyone wants to take it away.
  • Hello again to Briony and Harriet who dropped in but didn't stay long.
  • Kevin has done a successful repair on a Dell laptop.
  • Dan is looking at new uses for games controllers with 15-pin D plugs. One could be a handy remote control for a robot car, another might be an X-Y axis controller.
  • More laser cutting took place - we need to fix the exhaust, and longer term move the extract fan outside, or build some soundproofing around it.
  • Coolant for the CNC router arrived and the tank was plumbed in.
  • Some epic washing up occurred - the kitchen is now looking a lot less like an out of control microbiology experiment - please can we keep it that way.
  • The worst mugs were disposed of, and replacements donated by who have been using the laser cutter to create model buildings for their layout.
  • We need to get into the habit of taking photos for this blog.
  • Attendance tonight = 14

  • Attendance tonight = 22 Wow - that breaks all records so far!

Tuesday 15th September

CNC machine
Model car
  • The remote control car is now ready for the radio remote control. Same as the car, it is a home-brew remote (not something you get from a model shop)
  • Soldering practice for another member involved starting the assembly of a pocket radio set.
  • Paul B got the CNC milling machine doing some practice cuts, with Kris on dust extractor.
  • The new laser cutter was operational, and some work was done on it.
laser cutter
  • All the cables were removed from the window frames, and were packed in easy-access cardboard boxes.

  • We have to dispose of one 80cm x 140cm table, and the metal shop-rack.
  • Attendance tonight = 16

Tuesday 8th of September

Jon starting with shelves
Cheering on
Filling it up
More Shelves

Media:Tmp 22760-IMG 20150908 215754567909920.jpg

As planned it was mainly moving things around and putting up shelves.

Thanks to all that attended, specially Jon who had loads of fun setting up the shelves. All the uprights are installed, but we remain short of shelf material - donations of 8ft (2440mm) x 1ft (305mm) planks would be very welcome, otherwise we will have to buy some more. If we can replace the 6ft shelves with 8ft ones, then the shorter ones will be installed on the right of the main room.

Next phase: create a new work bench location between the doors to kitchen and cloakroom, and put up the tool racks.

An area was allocated to RHP for their stuff with the hope that it will not acumulate in the rest of the room.

We have a surplus table which we have offered on freecycle, one chair was scrapped, and one recycled, which between them gave up spares to make a third fully operational again. We had a potential new member called David who even donated some stuff, including a PC which we may use for the new laser cutter when it arrives.

Sorry to all the people we could not help, Mark, Chas, Dannielle, Richard and Jean. Special sorry for Jean as we could not find her bee frames.

Students at Kingston University - we are your local Makerspace/Makerlab or Hackspace, you are very welcome to join us during term time, we require no long term commitment, just a donation of about £1 per week.

Apple pressing (and cider making? ) in association with the London Orchard Project using the HUG apple crusher and press is timetabled for 10th October.

We need a volunteer to work their way through the donated PC's and work out: what's serviceable? what needs parts to re-commission? and what can be stripped for parts and the shell re-cycled?

Members - have you signed up for the email list? instructions on the inside of the front door of Little House.

  • Attendance tonight = 11

Saturday 5th September

Tuesday 21 July 2015

  • Carl's been experimenting with giant bubble mixture. He's found little

difference in performance in our climate, on a sunny day, between J-Lube based bubbles and Guar Gum bubbles. One J-Lube recipe makes a very convenient concentrated form of bubble juice, namely egoo. The popular Guar Gum recipe worked well for me though seemed better with 3 grams per litre. You can buy Guar Gum quite cheaply on ebay though you don't need much of it. Guar Gum definitely needs to be suspended in a slurry as part of making it, I used glycerin but I suspect rubbing alcohol works better. Finally, Fairy Platinum is supposed to be the best surfactant (soap) available in the UK for giant bubbles - just bought some, not tried it yet!

video of how to do it which in turn sent us to imgur image set and later linked to Jochen Kronjager website. Ring a bell? If anybody has another microwave let us know 4kV as Jochen shows in his web can be managed. It really works, though we really needed to soak it and add 3 spoonfulls of baking soda to the water. Hopefully others can post their videos and pictures. Fire extinguisher was at the ready the whole time. Electrons

were inconvenienced during this exercise.

Friday 30th January 2015


Little House is Leased to Ham United Group (HUG). Richmond Makerlabs is but one of many projects of HUG. Other users of the space are SWLEN (South West London Environmental Network). Mid summer a manager from rhp contacted HUG to ask if the caretakers for

the Ham Close area could use the space as a break point. Currently they
had a very small space where they could barely sit to have their lunch 

or tea break. HUG said that it was fine as long as they were aware that the space was mainly for community projects. Richmond Council made an agreement with rhp. rhp now pay a monthly fee for use of the space during the day. This continued fine until rhp raised some H&S concerns in before Christmas. Richmond Makerlabs acted on them as soon as they knew about them: last week.


Rhp Myles and Joel (from rhp) have been around and left and are very happy with the state of little house. They are going to come back and use the space. Things agreed are:

  • We will both clean up after ourselves. Rhp will even do a log for

bathroom. I said the latter was excessive but Myles insisted.

  • We will both turn off equipment, lights when not in use. Temp Heaters

will be plugged into mains and not extension leads.

  • rhp will request the council for extinguisher checks, appliance checks
and basic h+s kits.
  • Richmond Makerlabs will probably look into PAT testing. We have an

certified electrician in ham close and maybe leads on parents in local schools. If not rhp said they might be able to work something out. They charge £1 per plug. Andres will work on it but if anybody has any leads (pun) let me know.

  • rhp staff is only here to eat lunch and maybe tea. No 'hanging about'.
  • they have no issues with Paul or others coming by during the day.
  • We should still expect a visit from Richmond Council H&S
  • Attendance today = 3
