Hey Galp, Any chance I can buy like an hour of your time to help me trouble shoot my besc clone? I've made the PCB mostly modeled after your V1 board with some changes to suit myself. But I just wanted to ask a few questions on what you did with the firmware. For eg on inverting the current...

Got my drive boards today. Now to populate and test. .Fingers crossed. Mo

Hey All, Finished with the drive part of my design today. DAMN, it took a long time to finish this and it was a total $%# to route. I've opted to just go with a smaller 6 fet power stage right now TO-220 Package . I'll upgrade the drive board design once I validate the design and put some...

Got my PCB's from JLC and got my components on there. Just a few to solder on for the ADC inputs but so far everything on the board is checking out ok. Got the board bootloaded and VESC firmware flashed. Actively using VESC tool and all I/Os I can currently test seem ok. Including the Servo...

Zombiess, You are so epic good man. Thanks for the really in depth explanation. I can see already my controller is a bit of a joke in comparison to yours. But I'm coming off the old lyen controller days still have that on my ebike running irfb4115's at 30s 50a. Been doing that for YEARS with...

Damn, this is nice stuff.. I was working on a separated control and power stage controller but now I feel I missed out on picking your brain for a lot of stuff. Your control board looks nice. Is it open source? I would like to see the schematics if possible. Looks like you have optos on all...

Hey all, Been a hot heavy min since I've been on here. 2020 has been a complete nightmare for me. I lost my daughter River to a heart defect at 2.5mo old. She was a real fighter having had open heart surgery at day 5. She was born with TGA a disease where AORTA and PULMONARY arteries are...

Hey guys, I tried to do a search to find some schematics, I remember being available for the generic ebike controllers we all use/mod. I remember there was one posted someplace but a search didn't get me to where I was hoping. Anyone mind sharing a link or PDF of the schematics that are...

Anyone? Was really hoping someone else was interested in the design of this simple 2 transistor switch mode power supply. Mo

Hey Yall, Anyone ever find a schematic for the Xie Chang controller SMPS? This switch mode power supply is so killer I would love to know how to make it. It's so simple and useful. Has a crazy wide input range of 22v - 150v. My knowledge of transistors and making a circuit like this fails...

Thanks guys! I actually watched that video before I started.. It helped me a lot. I've wound a lot of RC motors in the past before but found it quite challenging to wind this motor up. I started using the technique from the women in the videos and it sped things up a whole lot! I staggered...

Hummmmmmmm You guys bring up a few pretty good points I hadn't even considered.... On the other controller that I had made successfully (6 Fet) I only replaced all the caps with 200-400v versions of everything and one transistor with a higher voltage unit.. Made tails for my two largest caps...

This is a pic of my work table.. Things are a realllllllllll mess right now .. But you can see my old controller sitting on the table .. This picture shows the up standing FETS I took the sinks off the controller and used them for something else. So this controller is currently homeless.

No it's actually a 6fet controller. 3 fets up 3 fets to the side.. You sort of can't see it in the picture. In the Picture your looking at the FETS out to the side. On the previous post I had made regarding that controller there is a pic from the top side of the Controller board which makes it...

Lol Tell me about it! I made this Controller last year and it really worked great.. My only main issue was it was a bitch to mount the FETS. I made the mistake of not getting them with holes in them. This controller should behave the same but should allow a much smaller sink source and be a...
