How the tech has evolved
What the first prototypes taught us
Almost two years ago we started installing our prototype lift controller with the help of some very brave early backers. Some didn't last a week. Everyone wanted a traditional lift controller back. We had to do a lot of work.
Our first box was simple: put in a capable brain (processor), then hook up two beefy solid-state relays to handle directions and a small relay to handle single-motor operations. Wire it all as best as possible and start working on the app where our product will shine. We quickly realized all the shortcomings. Wi-Fi range was limited. No remote controller. Relays failed without notice. Wire connections were fragile. Only two motors could be powered from the box.
Rebuilding the box
The only redeeming qualities were that the installation was easy, with plenty of wire space. So instead of using off-the-shelf components, we decided to rebuild the system on PCBs. This allows us to fit more components without adding a bunch of wires.
Keeping the remote and extending the range
To solve our problems, we first added a remote control module. Some people prefer the remote fob, and we guide ourselves by not limiting our users. Easy fix.
Next, we needed to add Wi-Fi range, so we made our gateway. We built a device whose only purpose is freeing your boat lift from your Wi-Fi so it can be talked to from further away.
Rethinking motor control
After that, we needed to improve our relays and add protection. We made each relay handle a single direction on a single motor, and for bigger motors we share the load across relays. This means relays have way less load and have an easier time. But what if something happens at the motor level that puts irregular stress on the relays? Then we needed to know exactly what the motors were doing. We added sensors. With the sensors, when a motor starts tilting toward misbehaving, we shut the whole thing down before failures happen. That protects the relays, but it also protects the motors. As a final layer of protection, we split the relays into different motor boards.
So let's say our two earlier layers of protection fail. The failure is contained to just that motor line, not the entire lift controller.
Making repairs and upgrades easier
The truth is we always wanted a system where parts can be easily replaced. This led us down a road where the components were easily accessible but not the best for the job. I think we have struck a balance. We have components that are more embedded, but we split up the system so when something fails you aren't looking at a whole lift controller replacement. And when it's time to upgrade, you don't have to buy a whole new box.
What comes next
The hardware is not ready yet. Our plan is solid, but we need to push things to the brink internally before we let you have a crack at it.
There is nothing out in the market like what we are bringing, and it's going to take some time before we all realize the shift. At my one-on-one meetings, at trade shows, and at our installation trials, I always find myself not being able to explain all the possibilities with our product.
