Hi, my name is Andreas and i am from Austria.
This is my first build, started at spring this year.
Introduction
At the beginning of this year i thought about buying a Evolve Board.
After some time i started to read in the ESK8 forum.
There i stumbled across “The Predator” build from @Eboosted.
At that point i knew “I need this shit!”
So yeah, here we are!
Setup
Trampa Solid Carver Deck
Trampa Mini Vertigo Trucks
Trampa Superstar Gummies Wheels
Trampa Motormount Pulley 44 Tooth
FlipSky Motor H6355 160KV
FlipSky Remote VX1
FlipSky Dual FSESC6.6 Plus
FlipSky Bluetooth Module
Bestech High Discharge BMS 12S80A
Samsung INR18650-30Q
Larcele Switch Waterproof
LED Driver LDD-1500HW
LED Front High Current
Lets begin. I have done some DIY stuff the last few years,
but after moving to a my new apartment i knew i need something like a workshop.
So there we start.
If someone asks himself why the hell it took so long to finish this build…
The biggest problem was ordering everything.
This realy was wearing me down…
The enclosur is from @Eboosted. Thx again for it!
The parts from @Trampa are fine, as expected and arrived quickly.
The parts from Flipsky took some time, but thats fine, China is far away.
One big problem, was waiting for parts from eskating.eu.
This also was my fault. After about two month, i still got nothing.
While sending some messages and e-mails i recognized,one item was not in stock.
At this point i split the order to several other shops.
And then it took me about two month to get nickel stripes.
AliExpress, Bangood, Ebay… Mostly poor quality. Man i was unlucky with this stuff…
I love sleeving cables.
So i thought about disassemble the Flipsky motor.
Stupid idea. I damaged the screws, then the motor.
Again waiting for a replacment… God damn it…
It was not possible to tighten the belt.
After a conversation with Dave from Trampa, he send me two new belts (Thx Dave!).
The delay was not mentionable. The support was excellent.
I used black silicon to seal everything.
Also i thought about lights.
I do not like the idea to mount them everytime and recharging it after use.
So i bought a DC/DC converter and a bicycle light.
I had to remove some silicon and used a pluggable cable for the light.
If there is the need to remove the enclosure or turn the trucks, it would not be that big of a deal.
I destroyed several of my DC-DC converter.
At some point i finally got some information about my problem.
Adjustable DC-DC converter have problems with high voltage difference and high ampere output.
So i changed it to an DC-DC Constant Current Step-Down LED driver.
This so well done for a first build. I’m impressed that you got so much into that enclosure! Also the series wires is just beautiful. Goes to show that with enough reading you can achieve anything. full props my dude.
Really awesome build all around. Love the problem solving, and its very clear that you did your research and followed through on everything.
After all that work, whaddya think? How does it ride and do you enjoy it?
Welcome to the esk8 community!
To be honest, i never thought about black screws and the idea isn’t that bad either!
But you are correct, i love the grey accent.
Becaus of this reason i took silver springs and the black rims.
Because of rainy days and lack of safety equipment, i only could test the real basics so far.
As i mentioned in the building thread, i switched the trucks from street to carver.
I thought the steering was a little bit hard.
Also Alan Chau pointed this out in his building thread.
Probably i have to change the spring position too.
At an unknown speed i thought the board started to wobbel.
But again i have to say, i need equipment for better testing.
Moreover i have only done the real basic setup in the vesc so far.
I probalby also will have to tune that.
One of the biggests problems at the moment is: Snow is coming!
I am realy happy about the overall positiv feedback!
At some point while buiding, i thought about just deleting everyting.
I felt like it was not worth posting it.
But now i have to say it was a good thing to share the build.
Thanks!
real impressive for a first build, i’m sure you’ll have a great time riding it.
question - i’m still unclear why a LED driver (Meanwell LDD-1500HW) is necessary.
i got some because i was told the LED driver would drop down high voltage down to LED voltage, but it doesn’t seem to do that. i know you can dim via pwm signal, but that seems impractical for esk8…
First of all, i am no professional engineer or whatsoever,
so i will only tell what i know or how i grasp the subject.
It is exaclty as you mentioned: It drops down the high voltage to the LED voltage.
The LDD-1500HW has an input voltage range of 09V - 52V,
an output voltage range of 02V - 46V and an limit current of 1500mA.
You can read the forward voltage and forward current in the specific LED datasheet.
In my case i measured the current of the dissassembled light.
The LDD-1500HW holds the current at 1500mA.
I need some help.
I use the Trampa Mini Vertigo Trucks.
The Trucks are mounted in Urban Position.
Removed the Dumpas, moved the springs to outside position an tighted the springs.
I cant get faster then 30km/h because of speed wobbles.
When i move my body weight to the front position, it is getting better but still far from stable.
Next i will try to get some video feed if necessary.
Any idea to fix this issue?
well done dude!
awesome job on both for sure!
