M365 Electric Scooter – must have mods

I’ve been riding my m365 xiaomi scooter for quite some time now… over its time i have made a few mods to make it a better and more reliable ride…

First – The tyres.


Sticking with pneumatic are best, they are lighter and generally have better grip when they are in good shape (i.e. not plastic). The only downside is the tube puncturing every now and again. The slime you can inject into your trye also is pretty average, it increases weight slowing you down.

To avoid punctures I’ve found best to ensure your PSI is approx 40 – 50 PSI. I weigh about 70Kg, and find 40PSI pretty good.

Also, dont get the cheap tubes from AliExpress, get the slightly more expensive ones, they have a thicker rubber and so far have really lasted. See Amalibay here – https://bit.ly/2KKorBp

Second – the firmware and battery bms

If your lucky enough to have 2nd generation scooter you will not have to worry about the small and easily blown “z-fuse” on the bms. If you have one of the 1st gen scooters you can just replace the bms with a 2nd generation one. Easy enough to find on AliExpress.

Installation will require a bit of soldering and careful workmanship – as the battery can give yo a bit of a jolt if you short it out! (I’ve accidentally done it twice and it can give you quite the fright)

Also your going to want to load a custom firmware. The android app M365_DOWNG is going to be your friend, it can connect to your scooter via Bluetooth. Making the custom firmware has been made easy at this site –

Disclaimer : firmware mods can break stuff, be careful. Ensure you have 2nd gen BMS first!

I’ve started using another app on my android for my 365, it has a much better battery information display – “M365 Tools”. Pretty handy for watching your cell balance across the battery pack. You can see my battery is a bit out of balance at moment, with a difference of 0.042 volts between my lowest and highest cell.

I’m dabbling at installing an active battery balancer so i can auto balance the cells (they seem to fall out of balance some times).

Third – The handle catch

Get some of those rubber “reducers” to go in the hinge gap. Works a treat when its been worn down after extended use. Makes the connection more firm, and stops the horrible squeaking sound. Check them out here – https://bit.ly/2ZVr07e

Brave Browser – another non-ad web alternative?

 Brave is a web browser that has been about for while, but i only happened across it when it made its way onto the android platform.

It presents another concept which supports web content creators without subjecting viewers to horrendous ads, both in their content and in their speed detriment.

Check their site out here – https://brave.com

Crypto mining failed me (see coin hive here), ads are annoying and more and more likely to be blocked via various plugins and tools. The Brave browser blocks all ads by default and builds up a profile on where you are spending your time on the web. Contributions are then made to the various sites if they are registered to the “BAT” system, which is a way of rewarding the content providers.

My very brief experience so far has been positive, a fast browser which support all my chrome plugins – but with all ad-blocking etc built in. For the extra paranoid it also includes a private mode that utilizes ToR network. Oh and it has a web torrent client built in.

A pretty good summary / review here – https://coiniq.com/brave-browser-review/

Update;

It seems ad’s may be coming to the browser, but so far it looks as though they are “opt-in”. I’ve updated brave link above with referral ;)

Caching Forged Alliance Forever downloads

In additional to this post here about caching steam games

I’ve run a few LAN parties where downloading updates from the FAF servers can take a while. This is no fault of the FAF servers, just i’ll have up to 10 people hitting the same mod and we all sit there watching progress bars as it downloads.

solution : modify the steamcache container image to also cache downloads for FAF
added benefit : takes load off the faf servers

If you want to give it a go, all you need to do;
(you’ll need a bit of experience with docker / containers)

  • download and run steamcache/steamcache container. This is effectively a reverse proxy running nginx. You can download the image form here https://hub.docker.com/r/steamcache/steamcache/
  • modify /etc/nginx/sites-available/steamcache.conf file in the container. Add the following directly below the existing “location /depot/” entry (for steam) to cache all /faf/ URI requests;
location /faf/ {
try_files $uri @mirror;
access_log /data/logs/access.log steamcache-local;
}
  • redirect local DNS queries for content.faforever.com to your local server (above). I entered a host entry on my local DNS (pfsense : resolver)
  • profit

There is a built-in script /scripts/watchlog.sh that displays access.log and highlights in green any cache HITS (why i’ve left logging classified as “steamcache-local”)

Update : above breaks server side code (php pages), ensure they are not cached.

time to disable coinhive – hysteria ensues

See my previous post here – https://sigtar.com/2017/10/13/coinhive-alternative

So the trial of coinhive and associated monero browser mining has come to an end. It seems most corporate firewalls and security appliances detect and block access to my domain just being associated with the coinhive java-script.

Even though i was being a polite net citizen and disclosing it on the site – firewalls with strict polices dont give it a chance. Several public DNS servers have also block listed the site – hopefully this will be undone soon.

There is a lot of fear around the word “crypto” due to the more malicious crypto-locker virus and it seems that coinhive has been associated to similar hysteria and panic.

Note : the amount of “wasted CPU” is trivial as i would only expect people visiting my site to be donating some cycles. i.e. in most cases i wouldn’t expect and entire company / business behind a firewall to browse my website and be under threat of  mass “CPU stealing”
