DIY Wood fired Pizza oven from Stainless Steel Pipe

DIY Wood fired Pizza oven from Stainless Steel Pipe

During the last years i have been interested in building a wood fired pizza oven. I have investigated many possibilities ranging from building a brick pompeii oven,  a barrel shaped brick oven or doing the gym-ball casting trick.

What i didn’t even consider in the beginning was using metal. Then i heard some good reviews about pizza oven made from sheet metal, (Uuni pro and such). That got me thinking that steel could also be an option in cases where you didn’t need to store the heat or make bread long after firing up the oven, only to make pizzas. (more…)

DIY Kitchen gloves

DIY Kitchen gloves

Ever had the problem that you burn yourself even when you are using oven mittens. Fret not! Just take a pair of welding gloves and write “kitchen” on them. Now you will not burn yourself anymore.

DIY Wolf Detector

DIY Wolf Detector

I made a wolf detector.

It can tell if an image of a canine is a wolf or not. It can distinguish between a very wolf like dog and a wolf. It is a binary classificator, and has been trained on thousands of images on all dog and wolf breeds. I might connect it to a wildlife camera at some stage and do some interesting things with it.

DIY Fooball Rebounder

DIY Fooball Rebounder

Made an adjustable Football rebounder to practice first touch in soccer. There is almost no loss in ball speed due to the tight strings. It is like a tennis racket. The string is a nylon string meant for weed whackers. it is tightened with bolts on the side. The rebounder can be aligned in different angles so you can practice retrieving both high and low balls. There will be a youtube video about the build at some stage.

DIY Wooden LOTR Swords for the Kids

DIY Wooden LOTR Swords for the Kids

During my summer vacation I built Lord of the Rings inspired wooden swords for the kids. I love these kinds of projects, where you just make something because you love the craft, and someone will be very happy with the result. The image on the cover is Sting (That Bilbo had, and handed over to Frodo). The other two are Orcrist (Goblin Cleaver, that Thorin Okenshield got) and the last one is Glamding (which is what Gandalf had). Three elven swords, made in Gondolin.

DIY Bike wagon or Float cart

DIY Bike wagon or Float cart

Always wanted a float cart (Mjölk kärra in Swedish) Made one out of an old and broken bicycle trailer. You can add a handle and use it around the yard. We use it mostly for moving firewood from the shed to our house. You can also attach it to the bike and take stuff with you that you couldn’t before.

DIY Ventuuri aerator

DIY Ventuuri aerator

In order to oxygenate the wort, i created a nozzle for the pump hose . After the wort has passed through the narrow passage, the pressure decreases and air is sucked in through the hole aerating the wort, which comes out all foamy. It relies on the ventuuri effect. (more…)

DIY Temperature controller and brewery

DIY Temperature controller and brewery

DIT temperature controller front panel

Cut holes in the front panel for the PID display, buttons and switches

I made a PID controller for the brewery in order to keep the mash at a specific temperature enabling optimal enzyme activity. I ordered the PID and switches online. The pid controls 3 solid state relays, one for each phase. The brewery is heated with 2 6kW heating elements. I added a switch to the controller where you can set if one or two of the elements will be used. The switch controls two three phase relays so it you can choose which 3 phase power outlets will be powered. There is also a switch that controls a normal power outlet so you can turn the circulation pump on and off.

The UI for the temperature controller. Top row, left to right: PID, alarm (when temperature has reached a certain treshold), swith for choosing one, two or zero heating elements to be active. Bottom row: two extra switches that are currently not in use, a controller for the circulation pump.

one power outlet for the circulation pump, Two power outlets for the two heating elements.

Cables

Trying to fit all the relays. 3 solid state relays that the PID uses to contol the temperature of the heating elements (one for each phase). 2 normal 3 phase relays fo choosing if one, two or zero heating elements shall be active.

 

Added fan to keep the solid state relays cool. (the releays stand above heatsinks)

Testing the controller. It works.

The temperature sensor is attached to the circulation pump.

OMG! A hidden bathtub in a sauna?

We had to do a bathroom renovation and i decided to redesign and build our Sauna. The space is quite small, so we wanted to use it as efficiently as possible. When we planned the bathroom, we could not fit a bathtub, but we wanted one, so i decided to integrate it in the sauna. (Read more for pictures of the SPA) (more…)

DIY Laptop stand for exercise bike

DIY Laptop stand for exercise bike

I built this laptop stand for the exercise bike in 2011 when we had a campaign at work where you got points for exercising. You could win an iPad. Since it was getting wintery, I wanted to be able to exercise indoors. I had noticed that many of the podcasts and youtube videos I was listening to during my outdoor mountain biking needed that you focused on the screen in order to see what algorithm was being walked though etc. (more…)

DIY Throwing axes

DIY Throwing axes

Welded some scrap metal together into axe heads. Truned some birch wool into handles. They were very nice to throw. Although the handles broke quite quickly, so I made new handles out of metal. That turned out great. It is great therapy to throw axes. (more…)

DIY Snow Making Machine

DIY Snow Making Machine

This was a project i did in 2008 i think when the kids wanted snow. It consists of two nozzles spraying high pressure water and one nozzle spraying a combination of high pressure water and compressed air. When the compressed air expands it takes energy from the tiny surrounding water droplets which freezes and allow the other water droplets to form snow crystals around the nuclei.

DIY Ocean Kayak

I don’t think i can find images from this build. My first and only glassfiber project, in glassfiber. The form was rented. I love the solitude on the water. I was able to learn an Eskimo roll on this one.
