About us

Our history, values and vision

The SuperTrickler® started as a personal project, back in December 2019, after Rex Petersen – a professional precision loader and director of MODGUNN SECURITY ApS in Denmark – became frustrated with the available gun powder measuring equipment.

Who are the poeple behind SuperTrickler®?

Rex

I was born in 1965 in a small town in southern Zealand, Denmark. From an early age, I loved building things, solving problems, and understanding how technology worked.

At the age of 15, I built my first computer—a Sinclair ZX80. That early curiosity for electronics, engineering, and innovation has stayed with me ever since.

After completing my military service in 1984, I began what would become a lifelong journey as an entrepreneur. In 1986, I founded my first electronics company, designing specialised testing systems for industrial customers. One of these projects took me to Malta, where I spent a year working closely with a client.

Over the following years, I founded and became involved in several technology companies. I opened CD Mekka, one of Denmark’s first dedicated software stores, selling computer software on CDs long before online downloads became the norm.

I was also involved in developing Computermus, one of Denmark’s early interactive computer books for children. My passion has always been creating something new, and I have never been short of ideas.

Later, together with two partners, I co-founded CANVAS Interactive, a company specialising in websites and IT security. We grew the business to 56 employees before selling it to the Finnish technology company TJ Group in 2001.

Although I enjoyed working in the technology industry, another passion gradually began to play a larger role in my life.

After obtaining my hunting licence in 1996, I developed a strong interest in hunting, precision shooting, and especially ammunition reloading.

What began as a small home-based business selling reloading equipment eventually grew into Guns & Powder, a specialist hunting and reloading store in Laurbjerg, Denmark.

As demand increased, we expanded from a 350-square-metre shop into a 1,100-square-metre warehouse. Over time, the company became one of Denmark’s leading suppliers of reloading equipment.

Following changes to Meta’s advertising policies, the company was later renamed Genladning Danmark.

Eventually, I decided to close the physical store and focus entirely on the webshop. By then, reloading had become much more than a business—it had become a genuine passion.

The idea for SuperTrickler began with a challenge I encountered while producing specialised ammunition.

I purchased five identical powder dispensers and expected them to perform in exactly the same way. Although each dispenser displayed the same weight, measurements taken with a precision reference balance revealed noticeable differences between them.

That simply was not acceptable to me.

Instead of accepting the limitations of the products already available, I decided to design and build my own powder dispenser—one capable of delivering the level of precision I believed reloaders deserved.

At the time, I had no intention of selling it. SuperTrickler was simply a personal engineering project created to solve my own problem.

During the development process, I shared questions and ideas in several Facebook groups. This was where I met Peter, an experienced software developer.

We quickly discovered that our skills complemented each other perfectly, and together we continued developing what would eventually become SuperTrickler.

When I later shared the project on my own Facebook page, the response exceeded all expectations. Reloaders from around the world encouraged us to make the product available to everyone.

Before long, SuperTrickler had grown from a personal engineering project into a global business.

Looking back, every company I have built has started with the same simple motivation: finding a better way of doing things.

SuperTrickler is no different.

It is the result of decades of curiosity, engineering, entrepreneurship, and an uncompromising passion for precision.

Peter

I was born in 1960 and grew up in a small country town in South Australia on the Murray River. Like my brothers, I learned to shoot from about age 5; guns and reloading were a normal part of my childhood.

In 1977, aged 17, I purchased a microprocessor – at that time, this was a new emerging technology. I built a computer and taught myself to program in assembler language. This led to a career in electronics, mainly in the areas of instrumentation, automation and process control. C/C++ became my core programming language throughout that journey.

When I, aged 55, due to a teenage injury, was forced to retire prematurely, very much against my desire, I needed something to do. I began refurbishing and modifying guitar amplifiers, and later decided to learn more about microcontrollers and affordable embedded systems (now that I was on a limited income).

I developed a highly efficient cooperative multi-tasking engine, giving these relatively cheap devices extraordinary power. In one of my systems, it originally struggled to cycle through its loop once per second, but after optimisation it was running around 16,000 times per second.

Jump ahead a few years. By now I had joined a Facebook group where I wrote code to help people all over the world. One day, someone from Denmark asked about an Arduino display. I immediately answered. Rex Petersen explained that there was already a complete library available (interface code), but I also wanted to send him the basics.

While working on a machine to dispense gunpowder, I noticed that rookie mistakes were typical among new users. So I wanted to make it run faster, be tidier and easier to use. From there the project became progressively more refined...

First move

Daddy Einstein

In general the equipment was either too slow, lacked features, had pseudo accuracy, sketchy claims or clumsy interfaces. To make matter worse, many commercial machines employed poor practices in relation to the use of the scales or balance attached to them. All of these factors compounded into one solution and so began the story of the SuperTrickler. 

Rex – known by his children as ‘Daddy Einstein’ – purchased a 3D printer, a few rolls of plastic filament and so began creation of cogs, containers, belts & tubes. Trial & error, success & failures, all working toward learning the craft and understanding in great detail what it takes to deliver a precision measurement device that can truly handle a variety of gun powders. At this time he setup a Facebook group for other re-loaders with the aim of community contribution to the project. However, interest was high and contributions by others were non-existent, so Rex went at alone. 

Steep learning curve

The first problem

The first problem; the electronics, Rex had not done any electronic design for nearly 35 years, and back then, everything was done using pencil and paper, from the electronic design down to the printed circuit board (PCB)! A big learning curve loomed and he began to dwell in the realms of computer aided design (CAD), modern PCB design and manufacturing and the prototyping process and modern electronic components and design. The project started using an off-the-shelf prototyping micro-controller called and Arduino Mega, some stepper motors and a bundle of hook-up wire.

Early attempts were traditional, using a powder thrower and trickler attached to motors and pulleys, all controlled by a micro-controller. Successful yes, but not meeting the expectations of Rex. There were still two major hurdles; the user interface and the variety of powders. Many companies claim their equipment can deal will any powder and although fundamentally true, they did not do it well. Rex in his ammunition company uses a great many difficult to use powders and this became an important design requirement. Then there was the user interface, Rex was using a rudimentary HMI (Human Machine Interface) and wanted much more than simple press buttons and basic display functionality. It was this requirement that led to a partnership with Peter Kowald.

Help from overseas

A needed partner

Rex had discovered on the market a colored touchscreen HMI ideal for the job, however interfacing with it was difficult and out of frustration posted on a forum asking for help. Peter – a retired automation and process control engineer – was sitting in Australian reading Rex’s cry for help and responded with “Hi Rex, yeah mate I can help you, I have built an interface library (software) for that device and you can have it, if you like send me your code and I will pop it in and get it going for you”. So Rex sent the code to Peter. He integrated the HMI code and while there (having 30 years of C/C++ programming experience) thought it would be nice to tidy up a few things and nudge the structure of the code a bit here and there. He also threw away the scales interface code to write a much faster version etc. etc. He sent the code back to Rex with a “there you go mate, hope all goes well”. To cut a boring geek story short, it was not long before Rex was asking for other complex changes. Although Rex had done an impressive job of programing his micro-controller, he soon realized that to take it to the next level was out of the amateur programing league and a phone call was made to Peter to discuss a partnership in developing the SuperTrickler.

Next step

A deal struck

Peter was an ideal choice. As a country kid in his youth, he had much reloading experience, so explaining the goals and hurdles was not like talking to accountant who knows the prices of everything and value of nothing. So a deal was struck. Peter would concentrate on the software, Rex would design and build the mechanics and do the live testing. They would both discuss the issues and look for ways to resolve the electronic requirements and mechanical delivery challenges that were to lay ahead.

Powders

Patent issues

Next on the agenda was the variety of powders. The concept of throwing powders through a measure has been with us for a long time. This method has one major advantage (speed), however it has two major drawbacks. It was fast but the measurement had to be hand dialed and it often would have to be wrestled with to measure large kernel powders. It became obvious that throwing powder in this manner was not a good solution and Rex hit upon the idea of two tricklers – a large tube for bulk trickling and a fine one to finish with precision. The design was easy enough, however by accident Peter came across another unit available on the market at the time with two tricklers with patents on their design. This brought the project to a rapid stop. However, after detailed investigation into their copyright and some legal advice we found that we would not breach the patent as our design (apart from two tubes) employed no other characteristics of the design. The SuperTricker Facebook community was extremely helpful as some of the members had experience or contacts in this area and assisted in overcoming the legal issues.  Rex had always been totally open on the group about all aspects of the design and progress and it was not long before other manufactures of similar equipment began to change their design to this same dual trickler arrangement.    

Manufacturing

A problem that needs solving

With the HMI, delivery speed and systems out the way, the design called for the next step; to address a host of reloading issues totally ignored by other manufactures. By now Rex was up to speed with the electronics and the off the shelf Arduino Mega had been replaced through several iterations. Now it was a dedicated and sophisticated electronic computer board with a touch screen display. It contained all the devices and components needed to control the SuperTrickler and interface with other devices.

By this time the SuperTrickler was attracting worldwide attention and both Rex and Peter’s time started to shift away from the drawing table and into correspondence. Out of this came a collaboration with an American company that would manufacture the unit and distribute it worldwide. Rex and Peter could get back to the drawing board to concentrate on the details at hand with the solid goal of making the BEST precision delivery unit that is feature rich, with a robotic interface, is user friendly and would cater for both the beginner or basic user and the power user. The aim was not to have another unit on the market. Rather, they wanted a unit that re-loaders wanted (Facebook group) designed by re-loaders, built by re-loaders for re-loaders.

Time

Quallity takes time

Frustratingly, research and development takes time and money. It’s hard to create a machine that does not shy away or talk over and around issues that plague re-loaders (whether they know it or not). This was compounded by the worldwide electronics component shortage. To turn lemons into lemonade, this time was used constructively to make design refinements, add artificial intelligent, refine trickler tubes (already refined) to another level, refine the impact of air currents to a breakthrough level compared to other commercial machines, along with many other things that only the detailed precision loader would ever notice. This additional time has allowed them to design structural improvements to enable cheaper manufacturing, lowering the cost to the purchaser.          

When true precision matters, Rex and Peter are proud to have designed and brought to the market a highly advanced, affordable powder delivery system.
