Replacing D-Cells with 28650

Been trying to consider how to replace my 2D Maglite battery powered to a modern Lithium 28650 – 5000mah.

2D Cells was 2X1.5V=3V total

2X 28650 Batteries give 2X4.2V=8.4V at full charge, dropping to around 7.6V when flat.

Had to replace the led bulb with a new one, made a couple of battery holders to keep the Lithium cells in the middle of the torchlight, used a 3 X 8mm disk magnets to connect everything together and then had to make a new end cap spring to accomodate for the new length of the batteries.

It all works and it is substantially brighter than the previous setup.

Manual Machine

Built this with Now during the weekend. It is a training tool for making wheelies without pedalling which are called “Manuals”…so this is a “Manual Machine”…

It is made so that it can be dis-assembled easily to put in the garage.

There is a single nut to hold the balancing arm, which we 3D printed.

Slicer Nut

The Berkel slicer is very nice and very precise for cutting thin slices of ham, however it is a pain to clean as there is some sort of nut which is difficult to remove.

Here comes 3D printing to the rescue. Made a few versions of a removal tool and settled on the final simple design of a “Captured” nut.

It works very well and the white PLA print, looks appropriate for food and “white goods”.

In the background some paper “thinking” about a manual machine for Noe ! Soon to be built ….

Brioche – Everybody likes it

I really like the brioche that my mum makes when we go on holiday in France during the summer. It is just a pain to wait 12 months to have some brioche! Decided to get a new bread maker from Panasonic (the old one still had an American plug and we have been back from the USA for 8 years now…)

The Brioche recipe is very good and works very well with the automatic bread maker.

 

 

 

Ingredients :

  • 400g White Flour
  • 1 Teaspoon Salt
  • 1.25 Teaspoon Yeast
  • 2 eggs mixed with water so that it makes 280g
  • 4 Tablespoons of dried milk
  • 4 Tablespoons of sugar
  • 50g of butter early in the recipe and then 70g of butter later. (cut in 2cm pieces). Make sure butter is cold from the fridge.

 

How to make :

  • Mix all the ingredients (with the first batch of butter). Ideally all of them at room temperature.
  • You should get a nice dough ball.
  • Then mix the extra butter by kneading for 3 to 5 minutes.
  • Leave to rise for a couple of hours.
  • Cook in over / breadmaker.

Fish Migration

Fishes have moved house during the garden refurbishment…they now live in the garage…it was not easy to move everything and keep the carp in the bucket!

Is it really necessary ?

First drive, ever, in first car, ever, ….is it really necessary to be a Lambo…or was it a Jag…growing too fast

More Ham

I am continuing my experiments in spices and cooking temperatures as well as a method for cooking such as sous-vide or slow roast etc…

Latest is normal roast in the oven with a temperature probe inside the ham to check “when” it is done rather than relying on weight etc…Target temperature was 63 Celsius.

Interestingly, once the ham was removed from the oven, the temperature continued to rise for a little while. As a consequence, a 63 Celsius in the oven ends-up being more like 65/66 once out. This is very different compared to sous-vide cooking which only cooks at the exact temperature.

In the oven the “180 degrees” outside of the ham, slowly make their way to the center until the center is at 63 degrees.

In sous-vide the whole ham will cook evenly to the 63 degrees.

This ham was made with some spices and 2 table spoons of brown sugar to coat the ham. Delicious…

Trivet 2

Made a new Trivet design, inspired from some Pinterest boards I had visited months ago…

Laser cut from 3mm Bamboo, then glued together to make 9mm thick, then sanded to 2000 grit to give nice feel and sheen.

The fit could be better, I did not take into account the Laser Kerf in the design and also I might have botched the laser settings in terms of focus and therefore beam thickness.

Compared to the “3 Branches” version, this one would be more expensive to produce as more cuts and trickier fit. The “design look” is nice but probably does not warrant the extra effort to produce compared to the 3 branches one. Still, I like it.

I should sign it.

Handlebars

Made a complete project with my XCarve. It all started with a friend who was trying to repair a second-hand child bicycle trainer.

The handlebar was broken and glue was never going to work.

The part is not very complicated but needed some smooth curves and a recess for the connection to the steering mechanism.

I created the fusion 360 3D model, then created a CAM setup, then posted all this to several G-Code files on my home network, [one for the pocket and the holes, one for the contour] then went to the garage and ran the G-Code on my X-Carve with a 10mm router bit at 16.000RPM, 3mm cut depth, 600mm/min feed.

It all worked perfectly ! for once…No broken bits, No burning or parts, No flying wood parts in the garage…

My friends were very happy and the fit is simply perfect.

Making a Stool with X-Carve

My first true design of something for the Xcarve. There has been a few mistakes along the way and still have not managed to get a final product from the machine yet…

I am close.

The router bits, feeds and speeds are something that you must acquire and work to make test cuts etc…until you get a clean cut that does not destroy the router bit or the machine.

I have had a few crashes and also made some part of the wrong size.

I am getting close.

I could have made this simple stool using traditional techniques in a lot less time but I want to be able to get to a complete project where I know, I could simply put a large sheet of wood and press “Go” on the computer and it would cut all the parts needed to make this simple stool.

I designed it in Fusion 360, then created all the tool paths for the X-Carve in the Cam environment.

I am now using a Dewalt router, which is better than the previous Bosch Colt for which I destroyed the collet. I re-built the X-Axis as well to give it more rigidity when I installed the new X-Controller.

Wood is 18mm thick

Router bit : 10mm

Cut depth :3mm

Router Speed : 16000 rpm (dial setting 1)

Feed : 600mm/min (500mm/min works as well with less heat generated in the router bit)

Plunge : 150mm/min

No lead-ins or lead-outs.

Repairs for the pond

The electrics have been playing funny for a few months. The RCD is tripping the whole house when I use my Laser…I have been trying to understand what is the source of the problem exactly but simply cannot source a consistent behaviour of fault.

It trips “mostly” when I am in my garage using my Laser…

So the whole family thinks it is the Laser which is faulty.

I am not sure, … actually, I am “often” in the garage. I am often using the laser. It has tripped even when I was not using the Laser or even being in the garage…

I think the Laser takes the RCD over its maximum and makes it trip.

I think the water pump of the pond is a more likely source of the problem as well as the electrics of the plugs for the pond.

So I have decided to replace the whole system. Replace the pump and new outside electric box, I am using a smart electric box with relays and a computer tracker which keeps an eye on the pump for its electric consumption and can sound an alarm in case the pump gets to work too hard.

It was a pain to do…

One day I will connect it all using a Raspberry Pi to track consumption and monitor temperatures etc…I have a Pi already setup in the conservatory  “taking pictures” daily and sending them to my email.

I got my Farmbot ! – must wait…

Got my Farmbot a couple of weeks ago [here], I must wait until the garden is all re-done to be able to build it into the glass house I am planning to install in the back of the garden.

It is exciting to be part of a very early project…the enthusiasm of the creators of this project and the overall sense of community is brilliant.

Will post more when I have managed to find the time to build it!

Here a few pictures of this very well put together kit.

It is controlled by a Raspberry Pi using open source design and software
