TIA-485 PIC tutorial
I just finished up a basic tutorial of using TIA-485 (RS-485/EIA-485) with a PIC micro on 0xEE.net.. this will be part one of at least 2 or 3 articles. 0xEE.net PIC Talks RS-485
First Hexacopter Flight
Wow, an action packaged summer so far… no much bench-time unfortunately but work has let off and I’m working sub-50 hour weeks again thankfully. I did get to spend some time this weekend on the bench but really not much. I worked on an article for 0xEE.net and a little fixing for the wife. I…
Project: The DJI F550 Hexacopter
My first week back from vacation. My lab needed some re-organizing, I brought back a ton of goodies… tools, etc. too much for the lab so I needed to organize a little better and utilize what space I have a little more efficiently. This is my excuse for being overly absent the last to weeks.…
Vacation Tidbits
I’ve returned from vacation and brought back a ton of tidbits to share over the next few weeks. I left the beautiful Pacific Northwest to work on my ranch house in Meade County, South Dakota. I had a number of projects I hoped to complete while there and got through a fair portion of my…
0xEE.net UART / Weekend Tinkering
We did it, 0xEE.net is live. Our first post is a very detailed look into the PIC UART. This article is a stepping stone for other projects we have lined up. Tell us what you think! In other bits I haven’t had a lot of time to do other things, I have been busy building two…
W0PCE ESR Meter Kit Build
In the Sept – Oct 13 ARRL publication of QEX, W0PCE has a nice article on ESR (Equivalent Series Resistance) meters. I won’t go into details because I did on a blog post I have saved in drafts for when I finish my own ESR meter but the one sentence version; An ESR meter tests…
Project: GPS2 Click with the PIC Clicker
I’m working on a GPS-based WWVB simulator and I’m pretty close to finished. I wanted to share up to the point where I add on the WWVB circuits and have it stripped down to just the PIC development board and GPS module. This is on a Mikrelektronika PIC Clicker 18F47J53 development board and a QUECTEL…
PIC-based Dumb Terminal
Okay before you start; I know.. I know.. Because I’m shooting for a VT-100-ish emulation my project is technically an “intelligent” terminal but not in a sense that it runs an embedded OS/IP-based, but in the sense that it decodes ANSI ESC codes.. it’s still a freakn’ dumb terminal in my book. I’m just about…
A new bench-friend!
Who needs more kids when there’s spectrum analyzers to be had! I haven’t had a lot of time to play with this because well, I just got it. I will sit down and really tear it up … I have filters-galore to design and tune now! Someone said they needed to take photos of the…
Project Updates, 20140429
Frequency Standard Project: I took an old milli-volt meter which is long dead and gutted the case. It was a lucky day when I could just flip the face plate over and I had a ready-made front plate for my frequency standard. I got my power supply in yesterday from Digi-Key. It was $19 1470-2284-ND…
