I trying to figure out how I can access my car's ECU through a serial interface. My goal is to have a microcontroller connected to the ECU so that I can monitor some ECU inputs (door open/closed, engine running/off, etc) and also directly control some ECU outputs (sound horn, flash headlights)...
I downloaded the service manual which had a good troubleshooting flowchart. The main board was bad, $450US to get a replacement module from Tek. This scope is simple to repair, everything is modular. Power supply is discrete components, the rest is surface mount. Very pricy to get boards...
I turned on my scope last night, and the display did not show the typical dark blue screen with language selection that comes up on powerup. This scope has a colour LCD screen, not a CRT. The screen colour is now a grayish/light blue, and stays that way for hours after I turn it on. The...
Re: TCP UDP port scanner
I recently used a Microsoft tool called "port reporter." It will tell you what you need to know in excruciating detail. It is installed as a service. You start/stop the service whenever you want, and it reports on activity between start/stop.
I am thinking about my next generation wireless remote control application. My present app uses a Parallax stamp BS2px with a wireless transceiver and an RS232-ethernet interface module. My design is way too expensive, so I've got my eye on a new RF transceiver, and I'm having some trouble...
I owned a house that had aluminum wiring. It's possible to mix copper and al on a branch circuit, but you must use gray anti-oxidant paste + Cu-Al marrette connectors to avoid the risk of a house fire. The marrette connectors are very hard to find in the marketplace now, so it is best to avoid...
I'm looking for a cheap interface to connect my Dell laptop to my Tek scope, which has a GPIB port. Commercial offerings are an absolute ripoff, don't understand why they're so expensive. I've found some older threads on this board, but I thought I would post again to get some recent feedback...
Hi all:
My Gould DSO display has crapped out, unlikely I can fix or get fixed locally. My design work has stalled because my scope is shot, so I need a new scope soon. I'm thinking about the bitscope BS310U at $500US. I like the portability aspect, and I'm now a bit leary of buying used on...
