DIY Keg Floating Dip Tube Mk3

Gus — Fri, 18 Oct 2019 04:04:41 +0000

Move over Mk2 In Mk2 version, the float was signficantly simplified however setting it up was difficult and I started to move away from the idea of using Oetiker clamps inside the keg (is it safe?) MK3 would have to be the simplest design yet! Mk3 Simple Float Mk3 works as follows The same float …

F-TPMS Fermentation Monitoring Part 1

Gus — Thu, 26 Sep 2019 04:00:59 +0000

About 2 months ago I saw Andreas Speiss talking about using TPMS sensors for monitoring his bottle carbonation. He was having to fabricate a cap that could accomodate the sensor. It got me thinking. Why can’t I just use the outboard sensor types with a valve stem and call it day? So I decided to …

I2C/IIC longer cable runs without extenders

Gus — Tue, 17 Sep 2019 05:43:05 +0000

Recently I was building some custom boards which had an 0.96″ OLED display that was remotely mounted. In my prototyping I noticed no ill effects from extending the 4 core cable to the OLED display. The wiring comprised of GND, 3.3V, SCL and SDA signals. I had 4.7K pullups at the board side. Then came …

DIY Keg Floating Dip Tube Mk2

Gus — Sat, 14 Sep 2019 22:54:49 +0000

Move over Mk1 In Mk1 version, there was a filter. I got feedback that this was causing grief when it got blocked. Additionally the build cost was on par with the off the shelf Fermzilla float. Well, we can’t have a situation where DIY cost more in parts than the commercially available item! Mk2 Simpler …

DIY 54Vdc 30A Battery Bulk Charger – Mk 2

Gus — Mon, 26 Nov 2018 02:04:36 +0000

Look Ma no fans! In Mk1, I used a 48V UPS. In Mk2 I use two 24V APC UPS transformers in series. Basically I take the two identical transformers and double the voltage output for the same current. This gives my power supply a 3000VA capacity! The donor housing for this project was a dead …

DIY 48Vdc 30A Bulk charger – Mk 1

Gus — Wed, 29 Aug 2018 02:53:00 +0000

Being off-grid means energy freedom for me. However freedom from the grid also means attachment to the whims of nature and the waxing and waning cycles of light from the sun, intermittent wind. There are days when my energy system storage gets low enough to warrant some stress about running out of power. The …

Grid Tied Solar Power As the price of electricity soars in Australia, solar power starts to become more financially logical pathway with much less total cost of ownership times (TCO). We can go down the route of getting a grid tied system using the STCs available to our homes but the usual topology is a …

DIY Tandoori Oven

Gus — Thu, 01 Mar 2018 01:44:47 +0000

Tandoori Fired Meats Need I say more? There is something absolutely wonderful about meats cooked on skewers in a tandoori oven. The high cooking temperatures (technically unachievable by most domestic ovens), coupled with the smoke of fats and liquids falling onto glowing charcoal makes for an amazing culinary experience. Before I built my own, I …

DIY Keg Cleaning System

Gus — Wed, 07 Feb 2018 00:23:33 +0000

Last Call If you use a dispensing keg by racking your cold crashed but unfiltered beer, you will end up with some trub at the bottom of the keg which when it comes time to clean is a fairly simple task IF you have small enough hands and forearms. Over the last 2 years I’ve …

DIY Keg Floating Dip Tube !UPDATED Sept 2019!

Gus — Tue, 28 Nov 2017 00:20:05 +0000

Keg Residues I’ve been homebrewing beer for the last 15 years. I started (like most) with a plastic fermenter / bucket and used hopped extracts with adjunct brewing sugars and then bottling with priming sugar. Over the last 2 years I’ve migrated fully to kegs and I can say I don’t miss the bottling aspect …
