T1000LE – Testing, testing and more testing

After my post yesterday I did some further testing on both machines.My suspicions were confirmed by desoldering and testing Q502, it was shorted out on both machines. Stranger things As this 2SJ182┬áis a Power MOSFET capable of handling -600V drain-to-source, 15V gate-to-source and around 1 amp of peak current (as shown in the datasheet) something …

Toshiba T1000LE – These things just don’t want to work

As anyone familiar with these older battery-powered Toshiba laptops knows, these things are finicky at best when it comes to their power supplies. Especially electrolytic capacitors and, apparently, MOSFETS are a problem. The good A year-and-a-half ago I posted about my T1000LE and that it was back to life.That, as it turns out, was a …

Arduino OBD-2 library status

An update on the Arduino OBD-2 library is in place.To be honest, I haven’t been working on this for a while now, as my attention had somewhat shifted to my vintage computer collection.With that being side-tracked for now (as for why; you can read that in my latest Toshiba T1000LE update) I can finally focus …

Another T1000LE update

I thought it was time I posted another T1000LE update because (quite obviously) everything went not as planned.I really wanted to get the video done by now but editing is a lot of work and since the December festivities start early here in The Netherlands I didn’t have all the spare time I wanted.My aim …

Toshiba T1800 laptop harddrive repair

I finally got around to fixing the T1800 laptop I’ve owned for the last couple of years.This is a project that has been shelved for a long time as I thought it had a BIOS defect which tuner out to be a harddrive (and floppy, I’ll get back to that later) issue. I posted a …

Toshiba T1000LE progress and troubles

The new capacitors for the Toshiba T1000LE I talked about in my last post were delivered this weekend. I really was hoping to make some good progress, but of course I ran in to some troubles. The first problem being that unfortunately two of the capacitors are in backorder. They will take two(!) weeks to …

Vintage Toshiba laptops

This is just a quick post as I haven’t made one in quite a while, and for a change it’s not about OBD2 or ELM327 stuff, but rather about some of my Vintage Toshiba laptops. I recently acquired a vintage Toshiba T1000LE laptop which has, as the seller told me, “possibly power supply issues”. Basically, …

Arduino ELM327 library: First draft

As promised in a previous post, I've committed a very (and I mean very) crude first draft of my take on a ELM327 library for arduino to GitHub. It's largely inspired by the library I'm currently using, with a few exceptions: Support for custom init strings to be added Support for both HardwareSerial and SoftwareSerial for …

Arduino OBD-2: Library rewrite

So here's another (small) update on the arduino trip computer project. I keep running into issues with the arduino OBD-2 library (well, actually it's an ELM327 library) that require me to make modifications to it. So firstly I've added support for spaces in ELM327 responses and added a couple of init-commands to the library, as I …

Arduino OBD-2: Project update

I've posted an update video to YouTube in which I (hopefully) answer some of the questions that I've gotten over the last couple of weeks. Check it out here:
