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 …

Building a low-cost PCB Assembly Line Part I

Gus — Sun, 14 Apr 2019 22:52:32 +0000

I have been a maker pretty much all my life. PCB fabrication has always interested me from constructing prototypes on vero board to toner transfers onto dual sided FR4 board. As time went on, the through hole components gave way to the SMT parts that initially were OK to install by hand (eg 1206 and …

Φ80MM 6V 2W Round Style Polycrystalline Solar Panel FAIL

Gus — Fri, 01 Feb 2019 22:57:28 +0000

6V 2W bargain panel? I have been searching for a solar panel to power some of my standalone ESP8266/32 projects and I have evaluated a bunch of panels. This particular panel got my attention because of its clamied power output and efficiency. This is what the manufacturer/seller claims: Specifications Maximum power: 2W Working current: …

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 …

AC Hot Water Conversion to Solar DC

Gus — Wed, 27 Jun 2018 05:31:50 +0000

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 …

OMVL Dream XXI N DIY Communications Cable

Gus — Thu, 31 May 2018 01:28:52 +0000

Diagnostics A while back my LPG system started playing up. Strangely enough while running on LPG the car would stall intermittently. To make matters worse, when it did stall I was unable to switch back over to petrol! This meant I had to pull over somehow, pull the ECU’s fuse to reset the ECU so …
