Anker Charger (130W, 6 Ports, GaN) (A2155) Mini Review

Image
Good on Anker for shipping the product in recyclable packaging. Specs listed on the back of the box. Comes with a C8 power cable of reasonable quality, though I do wonder how long the rubbery texture would last before it turn into some sort of gooey mess.  The charger itself.  Specs printed on the bottom of the device.  Note that it comes with some decent sized rubber feet.  A hidden power LED lights up when plugged in - I really like this, gives a premium feel to the product! Port C1 Capabilities - 105 Watts Port C2 Capabilities - 65W Port C3 Capabilities - 19.98W Port C3 Capabilities - 19.98W Port C4 Capabilities - 19.98W Size comparison to the old Anker Charger It tapers a bit more than the older model, but it's definitely thicker than the older model.  It also weights a bit more - I'd say it's 50% chonkier by feel.  I'm pleased to see that the new charger still fits in my Bellroy Tech Kit (standard sized one).  Bit more of a snug fit than before th...

So glad something else managed to top the chart.  Also putting the phrase here, maybe it will catch on.

Mikrotik CCR2004-1G-12S+2XS Routing Performance

This is not going to be a full test report of sorts, but a quick note for those in similar boat, YMMV, pinch of salt, blah.  I've seen too many people on the internet saying CCR2004 (the SFP+ version) will do a shit job at routing traffic between ports, but never any supporting evidence, so I thought I share my own experience.  In my homelab I have a relative basic setup, with something like 10 IPv4 Firewall rules, 2 NAT rules, 1 bridge with VLANs. Routing performance on IPv4 I'm able to get something like 8Gbps consistent going between bridge ports. I seem to get a somewhat better performance on IPv6 maybe due to less firewall / NAT rules, something like 9Gbps.  Obviously if you have crap ton of rules like operating a MSP this will be miles different, but for basic setup I think this is a relatively good number for what this device can offer.  Happy home labbing! 

[Rant] VanMoof S3 Battery Drain / Dead Bike issue

Image
It's British winter, it's wet and cold.  Don't suppose anyone sane would be riding their bike out during this weather.  Needless to say, I stored my bike on the wall and didn't touch it for a long while.  I expected my VanMoof S3 electric assisted bicycle to be drained of battery when I take it back out. No biggie, I thought to myself, just plug it in, charge, and off we go again.  Nope. No no no. Nope, it doesn't work like that with the pretty face S3.  If you were unlucky like me and allowed your VanMoof battery to fully drain, your bike might never charge and becomes a super dumb single gear heavy two wheeled paper weight.  This is the second time my bike died of this cause, last time I sent it back to VanMoof to be fixed. They applied some firmeware update which was supposed to have fixed this issue.  Yet it reoccurred! So I did some digging to see what is actually going on. Based on my diagnosis, this is what happened: 1. VanMoof S3 has 2 internal...

UK Virgin Media Hub 4 Link Aggregation is very broken (balance-rr)

Image
 Virgin Media in the UK currently offers a "Gig1" service that offers ~1.2Gbps down and 50Mbps up.  While the topic of mediocre upload speed is valid, that is a discussion for another time.  While the interface on the HFC interface offers 1.2Gbps downlink bandwidth, the Hub 4 modem itself offers only 4 x 1GbE interfaces, essentially limiting the usable downlink throughput to GbE (in practice ~940Mbps).  This bloc post covers an undocumented feature, which allows aggregation of multiple GbE ports on the Hub 4, and create a WAN connection that is capable of >GbE speed.  WARNING: While the bonding is stable with this firmware on Hub 4, the Round Robin (and alb as well) seem to fail for no reason every now and then. This does not seem to be ready for production use.  Date tested: 2021-01-31 ISP Modem:                              Model:         ...

Suzuki Swift MK3 (2010-2017) Passenger door rattle fix

Image
My swift has developed an annoying rattle coming from the passenger side door. I could hear it even radio turned all the way up, and it was very annoying whenever I'm driving over slightly uneven roads. After some extensive investigation, I've realised this is due to a pair of wires hitting against the plastic trim on the door. The fix is fairly simple, remove the plastic door cover , and apply some dampening material to the plastic panel. In my case I used some kitchen towel and attached it to the door with masking tape. Easy fix and it worked like a charm.
