I’m really having fun inventing new objects with my 3D printer. Much more on this shortly.

JPIV Throwing Exceptions

danreetz — Fri, 19 Apr 2013 20:11:15 +0000

If you are trying to do some particle image velocimetry, and JPIV starts, but throws exceptions, you probably need to install the Java Advanced Imaging Library (agh!). This is because Java Webstart, despite it’s best efforts, cannot install the JAI(L) automatically.

I installed all three installers from this page, which is a pain to find. After that, the errors stopped, and the velocimetry began.

Much of my career has revolved around Java/Android/Webstart projects. Why is Java still such a horrendously high-friction thing? It’s sad.

Details Inside

I’ve taken to placing a schematic inside of electronic devices as build them. This was commonplace in consumer electronics up until the late seventies, but was replaced by the ubiquitous “no user serviceable parts inside” label. Utter bullshit. Anyhow, this simple technique keeps me from having to look things up, even though looking things up is usually very, very easy. In this particular case, it keeps me from having to log into an obscure and poorly managed Yahoo Group. Aaahhh.

Brother HL2270DW Toner Cartridge Reset Procedure

danreetz — Sun, 27 Jan 2013 21:05:11 +0000

Have a Brother HL2270DW laser printer. Great printer, except that the starter cartridge lasted a measly 210 pages.

First, I tried this. Which didn’t work.
Then I ordered these inexpensive replacement cartridges from Amazon. Wish me luck.
Then I found this solution, which works. The post, originally by Phiolle, says:

Please do the following steps to reset the toner sensor.

- Open the front cover and leave open while completing the following steps.
- Turn the printer off.
- Hold the ‘go’ button while turning the printer on. All lights should be on.
- Release the ‘go’ button (or “start’ button).
- Press the ‘go’ button (or “start’ button) 2 times.
- Pause. All panel lights should be on.
- Press the ‘go’ button (or “start’ button) 5 times.
The toner light should be off. (error may be flashing)
The paper light should be on or flashing.
- Close cover. The ready light should be the only light on.

It works. Quoted here for posterity and google-ability.
