Fermented Dairy Composition & CFU Estimator

Gus — Sat, 14 Mar 2026 23:47:41 +0000

Exploring Probiotic Species for SIBO and Heart Health Over the past few months, I’ve been diving deep into the science of probiotics and their potential to support gut health, particularly for conditions like SIBO (Small Intestinal Bacterial Overgrowth) and cardiovascular disease. My focus has been on specific bacterial strains that have shown promising effects on …

How to Use the Fermented Dairy Composition & CFU Estimator

Gus — Sat, 14 Mar 2026 23:08:39 +0000

This calculator helps you design a fermented dairy batch with the right fat, protein, and sugar levels to support probiotic bacteria growth — and then estimates how many colony-forming units (CFU) you’ll end up with after fermentation. It was built with Australian home fermenters in mind. Unlike the US, Australia doesn’t have “half and half” …

ESP32 ADC to measure below 100mV

Gus — Wed, 01 Apr 2020 21:43:38 +0000

Just a short post to cover how to measure voltages below 100mV. I recently was trying to use a HP Common Slot PSU to drive a electrolysing unit. Instead of using my own shunt I decided to use Pin 34 IMONITOR to measure the current output. What i found was that for currents under 5A, …

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 …
