IKEA FYRTUR wireless blind: Switching from battery to permanent power supply

I have mounted an IKEA FYRTUR wireless roller blind in a position, where it is difficult to get access to the battery chamber to recharge the battery.

So I decided to replace the battery with a Universal Power Supply. The process turned out to be rather simple.

Battery operated IKEA FYRTUR blinds to direct power supply

1. In an electrical store, I found a Universal Power Supply with variable voltage output, among which was 7,5V DC (2.25 A). It was close enough to replace the standard battery rated to 7.2V DC.

Price around 20 €.

2. Remove 4 screws at the angular battery cover upper left side of the FYRTUR chassis.

3. Use a thin piece of metal to loosen the angular part at the left end of the chassis. Carefully lift the cover upward.

4. Remove the battery.

5. Drill a small hole for the wire into the battery chamber. 7-8 mm may fit. I made the hole in the battery hatch, but you can also place it elsewhere to allow the wire to connect to the battery contact plug.

6. Draw out the battery chamber. On its left side there is the battery contact plug with 4 legs. You will only use only the two outermost pins. Looking at the backside of the battery plus you can see two wires: a white (-) and a red (+). It is difficult to connect the wire from the power supply here. Use instead the pins at the inside, but note where the red wire is connected as this must receive + 7,5V.

Reassemble

7. Pull the cord through your hole in the battery chamber and solder the two wires to the outermost pins in the battery chamber. In most cases the positive wire from power supply will be marked with a white stripe in the black isolation. This wire must be soldered, so it connect to the red wire on the backside. If in doubt use a voltmeter to check.

8. Now assemble the battery chamber and its hatch in the chassis again in reverse order. Be careful to insert the small round pin, which functions as a shaft for the hatch.

Now you don’t need to care about recharging the battery in FYRTUR any more.

Hackers Help: How to attach headboard to ESPEVÄR mattress base?

I’m trying to figure out if a headboard can be attached to an Espevar Mattress Base , and how to accomplish that. I’m looking at a standard metal headboard (because I just prefer the look of curved metal to what IKEA offers) and am not interested in a slat base with just a mattress on top, and a wall mounted headboard is not an option due to renting. Thanks for any help! ~ Amy *** Hi Amy I’ve not seen the ESPEVÄR in person but I believe it is possible to attach a headboard to it. From the website, the ESPEVÄR looks like a regular wooden slatted mattress base under a bed base slipover. As to how to attach it, that will depend on the fittings on the metal headboard. So you will just need to get the right hardware to secure the metal headboard to the wooden frame. And make some small openings on the slipcover to let the fixtures to go through.

Kitchen renovation reveal: Rhombus wall steals the show

It’s been a while since I did a home tour. If you’ve missed the previous reveals, you can catch up with my Master Bathroom remodel and Guest Bathroom reveal . Today, let’s focus on my kitchen renovation. Hands down, this is the most used room in my home. I spend crazy amounts of time in here, even when I’m not cooking. Just off to the side of the kitchen I converted an awkward space into a reading nook . In the mornings, I sit and read or pray and meditate, before it gets too warm. And on the other side, there’s a work-in-progress plant wall / indoor garden which also takes up a lot of my time. So, all in all, lots of traffic in here, and that’s not even counting cooking and eating time. The kitchen is definitely my favourite room, because the transformation is huge and I love how it turned out. Kitchen renovation: The before House 17 when I first got it, actually had 2 kitchens, which is a very common “Asian” home concept. First, the “dry kitchen”, which is where you make simp

IKEA sofa with genius armrest storage

Bet you never knew your sofa armrests were prime storage space. Ok, so the guys at IKEA are the masters of hidden / secret storage everywhere. In fact, one of the things I most loved about the ESKILSTUNA sofa series was the undercover storage on the chaise lounge, but… what? More than 80 liters of storage space wasted on the armrests? NO WAY! I really don’t understand how they didn’t take that opportunity with several different armrest modules. Mobile chargers, cup / can holders, foldable tables, refrigerators… there’s SO MUCH space in there. I can’t stop thinking on different options! For myself, I went for two designs. First, a “full space” design on the (right) side of the chaise lounge. (The cavity fits two foldable chairs). Second, on the left armrest — a flip open section for “mobile charger / remote control storage / etc.”. Below that, a full-depth pull-out drawer, tall enough to store A4 sized magazines. This is the final result: Full space design, right of cha
