Als kind had ik zolang ik me kon herinneren een bril. Uiteindelijke sterkte ~-6. In 2011 wilde ik mijn ogen laten laseren bij VisionClinics, in de voorcontrole constateerde zij een gaatje in mijn netvlies (ablatio retinae). Dat is door het Oogziekenhuis Rotterdam vakkundig opgelost, vervolgens kon ik mijn ogen alsnog LASEK/PRK laten laseren bij VisionClinics… Continue reading Staar
Worx Landroid robomower
Update 18/06/2022: I removed the RoboClaws (don’t work on mesh wire protecting bad patches in recovery). Instead I added grip spikesgrip spikes now. First test run is promising! Grip does seem to have improved, and it’s not pulling the mesh wire loose. Update 16/06/2022: I tried adding RoboClaws spikes to improve the grip. There are… Continue reading Worx Landroid robomower
VW Sharan MIB2 unlock
We got a (second-hand) Volkswagen Sharan. Not a nice SUV model (which is the standard nowadays), however, the additional size is worth it with 3 young kids in ISOFIX car seats on the second row (for us). They easily fit together, and we have the third row (with Isofix!) if a friend would want to… Continue reading VW Sharan MIB2 unlock
Keeping our cats in the garden
Our cats used to live indoor, with a closed outdoor area where we would bring them sometimes. We have a house with garden now, and are not comfortable having our cats go outside the garden on the roads. The setup that has been working very well for us: Garden has a wire around it (mostly… Continue reading Keeping our cats in the garden
Burglar alarm using Philips Hue
Update: 04/05/2022: The sensors keep activating if a cat walls by. So far I have been unable to position them not to activate randomly because of the cats. After discovering I can read the Philips Hue Motion Sensor activation state as part of my letterbox notification system, I am now building an alarm to detect… Continue reading Burglar alarm using Philips Hue
Inflation-linked bonds
With the growing concerns around potential upcoming inflation, I’ve been wondering if our “money tree” should include additional protection against inflation. I want to avoid decorating the tree with dead matter such as gold or commodities. They may shine for a while, in the long run they’ll just pull down the branches. Equities in the… Continue reading Inflation-linked bonds
Ventilation, CO2, humidity, and temperature
Our house has been built in the 50s and uses “natural ventilation”. Essentially this means there is poor isolation and air can escape/get in through random holes. Ventilation is important, so that’s great. However it also means cold air can easily get in and hence we need a lot more gas to heat the house.… Continue reading Ventilation, CO2, humidity, and temperature
Bakfiets Batavus Fier 3
Update 11/09/22: Week 40 komt er mogelijk een eerste levering. Update 01/07/22: Voor de 4e keer schiet er een rem los op de Vogue. De lokale (Batavus) fietsenmaker repareert het steeds kosteloos (paar schroefjes), maar naast gevaarlijk is het wel een gedoe. De fietsenmaker zegt dat er een heel ander rem systeem op moet voor… Continue reading Bakfiets Batavus Fier 3
Spouwmuur isolatie EPS of glaswol
Update 09/09/21: Spouw is vandaag geïsoleerd door Vink. Vooralsnog (zoals verwacht) lijkt alles top gedaan. Update 16/09/21: We gaan in zee met Vink Isolatie Culemborg BV. Eerlijk verhaal. SKGIKOB gecertificeerde parels met een transparante herkomst van grondstof en lijm. Gevelonderhoud expert (dus mochten ze de boel verpesten hebben ze zelf de kennis het goed te… Continue reading Spouwmuur isolatie EPS of glaswol
Postal mail delivery notification using Hue Motion Sensor
Update 28/03/2022: I did it all wrong! There is no need (anymore?) to activate a light using the sensor and read the state. Instead you can pull the sensor state straight from the API every 10 seconds and set the result in a global variable. Using a second macro monitoring for the variable to change… Continue reading Postal mail delivery notification using Hue Motion Sensor
