Hello guys, I would like to offer you the remotes below. These remotes at their core(electronically) are the same but vastly different in terms of grip and style. It took me quite a bit of pcb and cad design iterations, failures, wrong parts selections/placements to get it all right and perfect.
I wanted something simple yet a quality product with long lasting genuine parts and a long lasting battery. I designed it to fit 102050 li-ion battery (differents sizes fit too just need to be within the spared internal dimensions) which lasts for quite a bit of time before it needs to be charged. It can be charged simply by connecting an 5V USB C cable, optionally it can also be charged wirelessly using a Qi charge pad.
My first setback was the flimsy and unreliable trigger switch. Most of the cheap switches can cause erratic input and can cause you a serious harm as it can cut out randomly during a ride which is incredibly dangerous. Even most of the name brand switches are rated for around 50-100K lifecycles. They are not bad but we can do better. The one i used is rated for 1KK(1 million) clicks which is well above what we need. The push back force of the switch is somewhat weak and it didnt feel well so i added a firm spring for a nice feedback on the trigger switch as well.
Throttle gave me a bit of a trouble as I didn’t want to use hall sensor because they are hard to get it just right and the output values are sometimes jumpy which is not ideal. I turned my attention to potentiometers but again most of the products are rated for 10-20K turn lifecycles. I found 2-3 products which suits our application and rated for 1KK(1million) turn lifecycle and they are incredibly steady. To achieve a smooth operation there’s also a ball bearing sitting between the potentiometer and the throttle.
The whole internal mechanical structure revolves around metal parts and we are not relying on plastic material on critical spots. Tapped plastic for bolts only lasts for couple of in and outs and after that it is compromised. I embedded metal M2 nuts and i probably disassembled the remote more than 30 times during testing which is well above what we need. Pillar that holds the spring for the throttle is also an M4 screw as well as the pillars for the lever and the trigger. Nothing is left to chance as from my personal previous experiences they can lead to unfortunate events.
There’s a single bi-color led to interface with the remote which can tell you the connection status, battery level and the current speed mode.
There are 2 buttons at the back(at the top on the trigger style) of the remote. Button B is dedicated to ws2812 lighting and button A is tied to battery level and speed mode operations.
If you are into lighting remotes come with optional ws2812 RGB lighting. You can cycle between 15 lighting modes and upon leaving it on the same mode for more than 10 seconds that specific mode is recorded into the memory so when you turn it on next time It starts from that specific lighting mode. Trigger style one comes with and extra led which is at the top butted against the led bar which further improves the effects and visibility at night.
What Im really proud about these remotes is there no buts, ifs or maybes when it comes to signal strenght&integrity and the build quality. These remotes just work no matter your enclosure or possible interferences from other devices.
Receiver can be configured with open ended cables, male/female JR futaba servo connector or JST PH connector.
Summary:
- PCB based, placed with a machine and reflowed boards
- Long life potentiometer and limit switch
- Genuine parts
- Place for a big battery
- Power amplified genuine communication modules for the best wireless connection
- 2 acceleration modes
- On board battery charger
- Embedded nuts to prevent wear and tear on the threads
- USB C connector
- (optional)WS2812 lighting
- (optional)Wireless charging
I have bunch of color options + for any customization or question you can pm me
In Progress
I also designed a simple to mount with no additional hardware ESK8 RGB lighting consisting of 56 individual leds. Idea is to power them directly from the battery esk8 battery with max 60V. Be able to control them(change modes, turn them on or off) directly from the remote. There are around 30 effects and first 2 are headlight tail light modes. Since we are controlling them directly from our remotes receiver I was able to create a mode that works just like a car tail light(brighter and flashing while braking). Lights are encased in resin to make them durable and completely waterproof. Can be top or bottom mounted and it is currently in testing stage. Coding and designing is done and finished. I will be able to share more later on.
extra leds forced me to change the hardware and the scematic quite a bit but so far so good. Abit more coding and testing is needed.
