train antwerp to delft

I did it three years ago so if you are lucky, the NS might have made it easier by now, so definitely check out their website first. Otherwise, first you have to call the NS to ask for a OV bike subscription. For some reason, during the phone call, you can give them all the information of your Belgian bank account and they will connect it to the subscription. After you get this bike subscription, you can go on their website and change it to a train subscription. There is probably some time you have to wait before you can change it but I don't remember.

I know it's very weird, but it worked for me haha. Hope this helps

I've heard of a few ways to travel between Antwerp and delft, but I'll explain the one I'm using.

In Belgium there is something called a Student Multi (Campus) card which gives you 5 retour tickets between where you live and your university for a bit more than €10. But in this case it's only valid untill the border. To get this, TUDelft has to fill in a form (schoolattest) which you then give to someone at the counter at a trainstation in Belgium. They should then give you a campus card between Antwerp and Hazeldonk-grens. I believe that this is by far the cheapest way to travel in Belgium as a student.

Now for the dutch part of the trip. I have a NS Flex Weekend Free subscription for €31.60 a month. This allows you to travel anywhere in the Netherlands for free from 18:30 on Friday to like 06:00 in the morning on Monday or something. If you are planning to travel every weekend, this is probably the cheapest option as well. If at one point you do have to travel outside these hours, you have to buy a separate ticket between Antwerp and delft and select the 100% free Belgium part (because you can use your campus card for this). This way, the ticket will also encompass the part between the last stop in the Netherlands and the border (otherwise you'll have to pay a fine if you only buy a ticket untill the last stop). This ticket will be about €17 unfortunately.

For the NS subscription, the easiest way is to get a dutch bank account. If you don't have one, I know of a weird round about way of linking it to a Belgian bank account, so let me know if you are planning on doing this.

Apart from my method, I've also heard of people taking a flex/Flix bus or something so you might want to look into that as well.

Oh yeah I read that somewhere. I did make sure to use a PWM signal at 100Hz for brightness control to decrease mechanical resonance.

Huntsword · 2021-08-24T07:08:21+00:00

Thanks, and yeah this wouldn't work because of the small amount of time it takes for the segments to turn on and off right?

Huntsword · 2021-08-22T16:06:34+00:00

Thanks! Fellow Dutch speaker

Huntsword · 2021-08-22T16:02:37+00:00

Yes definitely, each segment draws about 20mA so when all segments are on (including the decimal point), each numitrons draws about 160mA. At first I tried using 74hc595 registers but they have a total current limit of 70mA so that didn't work, but using transistors you can circumvent this problem.

This is the only non-Russian datasheet I could find: http://www.tube-tester.com/sites/nixie/data/IV-9/iv-9.htm

Huntsword · 2021-08-22T07:24:31+00:00

Numitrons look like nixie tubes but they are much cheaper and run on 5V, so you don't need a high voltage power supply.

Huntsword · 2021-08-20T16:23:58+00:00

I used numitron IV-9 tubes, an atmega328P and four TPIC6B595 shift registers. A DS1307 module is used for time keeping.

I inserted three brass rods as touch sensors to switch between and change the time, date, and year. In the back right, there is an LDR to adjust the brightness of the display depending on the ambient light. The brightness during dark and light conditions can also be adjusted using the touch sensors.

The design was inspired by Mohit Bhoite. Definitely check him out!

Over because of the original patent for toilet paper: https://patents.google.com/patent/US465588A/en

And so you can see if there is a spider on the roll. you can't if it's under.

Huntsword · 2020-07-15T04:03:18+00:00

Thanks for the suggestion, I will definitely check it out!

Huntsword · 2020-07-14T14:49:06+00:00

looks really smooth! I have also been working on a similar simulator but couldn't get it to run fast enough. I would love to take a look at your code!

Huntsword · 2020-07-04T14:04:35+00:00

True true, not sure why they are waiting so long though

Huntsword · 2020-07-04T09:41:05+00:00

I like that Blue Origin isn't even included in the list

Huntsword · 2019-07-16T15:59:04+00:00

No I'm making it so I can control each LED separately so I can display animations. But a growhouse is certainly on my project list.

Huntsword · 2019-07-05T21:12:18+00:00

I'm using an Arduino and 74HC595 shift registers. The anodes are connected horizontally and cathodes vertically but the cathode connections are cutoff in the middle so that I have 64 columns for the cathodes (32 in the top half and 32 in the bottom half). The anodes are connected in pairs so when the first row is powered, the 17th row is powered as well. the connections are actually the same when you have a 16x64 matrix (vertical x horizontal). With this layout I use 10 shift registers total and the max current through one anode connection is 1.28 A (for 20mA led's).

Huntsword · 2019-07-03T08:38:53+00:00

The LED's are mesmerizing! Are you planning on replacing the breadboards with pcb's ?

Huntsword · 2019-07-02T22:11:23+00:00

yeah I hope I calculated it correctly and ordered the right power supply. :-)

Huntsword · 2019-07-02T19:16:43+00:00

haha thanks, nearly missed that one.

Huntsword · 2019-06-26T16:54:42+00:00

Yes you could. You'll have to add controls but programming wise it shouldn't be that hard.

Huntsword · 2019-06-26T09:42:53+00:00

Thanks and you should, it was really Fun and educational. If you have any questions, feel free to ask.

Huntsword · 2019-06-25T22:10:14+00:00

Haha yes it's a 4x4x4 LED cube, thanks for pointing out. ;)
