Lego Boost candy sorter

Our project for the 2018 Coderdojo Belgium Coolest Projects exhibition was a candy sorter, built in Lego and driven by Lego Boost. I took pictures and wrote building instructions while disassembling the robot afterwards, so you can now easily build a Skittle sorter in Lego yourself!

Volkswagen UHV bluetooth touch adapter & its problems

My Volkswagen car has the "universal cellphone preparation" UHV built-in. This is the main part of a car kit, but requires an additional adapter for connecting to a cellphone. At first, I was using an adapter for my good old Nokia 6310, even after I changed to the Nokia E71. Connecting was easy: pair the phone with the "VW UHV" bluetooth entity, and done. This has the phone connected to the car kit at all times, so even non-call-related functions use the car audio system (e.g. voice recognition).
But progress will have its way, no matter what happens. So in comes the "bluetooth touch adapter". Instead of a phone-specific adapter, this is a small touchscreen device that slots into the UHV dashboard mount. Connecting a phone is very different now:
the Bluetooth Touch Adapter connects to the "VW UHV" device via bluetooth
the phone connects to "Touch Adapter" device, also via bluetoothThe device doesn't allow step 2 if step 1 didn't s…

How to solve "user locked out due to failed logins" in vSphere vMA

In vSphere 6, if the vi-admin account get locked because of too many failed logins, and you don't have the root password of the appliance, you can reset the account(s) using these steps:

reboot the vMAfrom GRUB, "e"dit the entry"a"ppend init=/bin/bash"b"oot# pam_tally2 --user=vi-admin --reset# passwd vi-admin # Optional. Only if you want to change the password for vi-admin.# exitreset the vMAlog in with vi-admin These steps can be repeated for root or any other account that gets locked out.

If you do have root or vi-admin access, "sudo pam_tally2 --user=mylockeduser --reset" would do it, no reboot required.

Link aggregation and VLANs on QNAP with firmware 3.4.0

The new QNAP firmware (3.4.0) supports 802.1q VLAN tagging, but you can't create multiple interfaces in different VLANs on the same physical interface through the webinterface.In the case of link aggregation (LACP 802.3ad for example), that means only 1 VLAN and 1 IP address can be used. Fortunately, QNAP allows full access to the underlying Linux system. Adding a VLAN interface goes like this (the example uses VLAN 234)# /usr/local/bin/vconfig add bond0 234 # ifconfig bond0.234 broadcast netmask
of course, this change is not permanent, a reboot will not automatically start this interface. I'll blog about making it permanent later.
