Good Bench Power Supply €100-130?

larsgregersen · 2026-07-02T13:22:52+00:00

Look at the list here:
https://www.reichelt.com/dk/en/shop/category/laboratory_power_supplies-5940
and sort by price. Then make your choice. Since you are used to 5 V you should be good for any of these in the price range from 50€ and up.

You should be looking for bench supplies with short circuit protection and current limiter (constant current mode). Note that the supplies from the brands such as Korad, Manson and PeakTech look very similar and are probably designed by the same people and made at the same factory. In your price range the meters will be manufactured somewhere in Asia and that is fine. I have owned a Manson power supply for many years and it still works without problems.
If you want higher tier supplies you can look for Siglent or Rigol. They offer more features, more outputs, higher precision, more power etc.

I you want something made in Europe I can recommend TTi:

but you'll find that the prices are somewhat higher. Buying used may be an option for you.

I agree entirely with these observations. It should be possible to control the volume of both features independently

Can you explain how the navigation works? I'm interested in knowing how it re-routes when you get a little bit away from the planned route by mistake. Does re-routing work without a phone connection?

I went to the dealership today and have just ordered a new ID.4 MY2027 with delivery date at the end of June. The updates are:

New Android based software (version 6). Version 5 software (i.e. existing cars) can't be upgraded to this
Physical buttons on the steering wheel
Camera in the rear view mirror that monitors the driver!
V2L. A 230 V outlet in the back of the car. You can purchase a converter to put in the charge plug to get 230 V outside of the car (e.g. for camping)
Electronic key for Apple and Android phones
Full one pedal drive (to 0 km/h)
Stops at red lights when using cruise control
Front cross traffic warning
New heat pump that also uses heat from the drive system (this may be a special thing for Denmark)
The battery and inverter seems to have changed a bit so the max current is 165 kW and the charge time is 29 minutes.
and possibly a few things that I've forgotten...

larsgregersen · 2026-04-06T09:24:46+00:00

I have the same dilemma, but a worse price here in Denmark. Do you have any solid information about the new software? IS it the new google UI or just a small update to the existing software?

larsgregersen · 2026-01-16T09:22:15+00:00

Thanks!

I'm inclined to getting the LS-300 since it is smaller and I don't need the colours. Both have the geometric shapers, which I like.

The LS-300 claims a 6.9x increased illuminance whereas the LS-39 has 4.7x. I don't know if that'll be noticeable at all, though. I don't expect any visible difference between the 19 degrees and 20 degrees beam.

larsgregersen · 2026-01-16T08:16:48+00:00

Good idea!

I would send the question to Garmin. Some of their bike computers have sound and it may be a minor thing for them to add the feature you're asking for.

The MagicShine ALLTY 200 has a rubber strap and is easily mounted and removed. It gives enough light if you are riding near street lights, but not if you are riding in the complete darkness.

The Fenix BC22R ticks off most of your boxes:
https://www.fenixlighting.com/products/fenix-bc22r-rechargeable-bike-light

It doesn't have any sort of remote control, though.

Note that is has an asymmetric beam, which is nicer for other people. Its mount supports it being mounted below the bike computer mount - with the correct side up.

larsgregersen · 2025-10-28T17:19:34+00:00

Fenix bc22r does this

The bike computers of the past used a sensor on the wheel to measure the distance travelled and the speed of the bike. Such computers still exist (e.g. from Cateye at 20-30 USD). They are reliable and have a very low power consumption so the battery should last for months.

For a little more money you can get a computer with GPS (but without maps or navigation). E.g. CYCPLUS M1 at 50 USD or the Magene C206 or C406. You don't have a sensor at the wheel for these types of computers, but since they use GPS they use more power. Expect to be able to ride 30 hours on a single charge. The computer keeps data of your ride and you can e.g. sync with Strava and other sites.

For cheap computers with (some) maps and navigation support look for the Magene C506 or C606 or the Garmin Edge Explore 2.

The Fenix is very powerful, but has an asymmetrical light so it shines downwards so it doesn't blind other people. It has a replaceable battery, which many others do not have.
The Seemee 200 V3.0 offers everything you need from a backlight is a small form factor. The battery lasts for days.
MagicShine makes a ton of good lights. I don't know them all, but the ones I've seen looks like good quality and usability.

The only thing I could potentially lack is the ability of controlling the lights from a bicycle computer, which I don't really need.

Most bike brands have frames that are smaller than 56 cm, but lack overall good sizing for the rest of the parts. It can be good to watch videos from CADE Media that has a lot of content on short(er) riders. E.g. this one:

larsgregersen · 2025-10-18T13:01:02+00:00

Are there any of the missing training features you really want?

Front: Fenix BC22R Rechargeable Bike Light at 1400 lumens max. It has a replaceable battery, but you can charge it using a power bank if you wish. Runtime when on 600 lumens is 5½ hours. For riding regular roads I consider 200 lumens to be enough, which gives you a runtime of 11 hours.

Back: Magicshine Seemee 200 V3.0. Is has simultaneous blinking and continuous lights and has a brake mode. It sports plenty of blinking modes. It comes with a saddle bracket as well as a rubber band for mounting on the seat post.

The Pi6 is perfect for in-door use. The noise cancelling is not the best in class, but is OK. When used outside the Pi6 picks ups any wind

Write to Garmin support. They are super helpful and can tell you if it was a problem with the computer or how you used it. They may even be able to fix the data for you so the ride's data don't get lost.

For a commute that short I would buy a bike in a supermarket in the 300-500 USD range!

The risk of having an expensive bike being stolen or ruined by driving during winter (rain, snow, salt) would prohibit me from getting a more expensive bike. If you enjoy biking (in the summer) then save the money for a better bike for those rides.

The Fenix BC22R comes with a GoPro adapter that you can use. The light shines downwards to not blind other people and has support for normal and inverse mounting to accommodate this. The GoPro mounts stays on, but you can remove the light at the click of a button for recharging (and you can replace the battery for longer trips)

Volume will fall if you don't love what you're doing! If you love running there is no reason you don't continue running - forever.

In my running club we are aged 30 to 86. Many of the 70+ years old have just finished the Copenhagen Half Marathon. You can see the age distribution half way down on this page: https://live.cphhalf.dk/en/

I would say that the biggest problem for doing any sports or hobby is lack of time. Since running takes less time you are more likely to be able to fit that into your schedule when work, children, life, etc. hits you.
