My DIY wifi module flasher/programmer. The ftdi (red module) is the usb input. White button is for chip reset. Green jumper selects native ftdi power (if 3.3v, which this module is) or put green jumper on bottom 2 pins for lm1086-3.3 regulator (when the ftdi module is native 5v). Yellow jumper shorts to flash; open to enable user-mode. 3v zener diode on 5v ttl tx line since ESP module is not 5v-tolerant on its inputs.

ShadowForge87 (or Dave to his friends and family) walked into the Internet Cafe and looked around. His laptop had run out of power and he'd forgotten to bring his power cable, so this place was his only choice if he wanted to get online.
Sitting down at the nearest desk, he entered the login details he'd been given by the pale looking assistent and waited. This could take a while, he thought, considering the computer looked like
something out of the 90s, but within a few seconds he was logged in.
Before he began visiting his usual sites, like BrickLink and Eurobricks, he'd better check to make sure there was nothing running that would track his actions. He was all too aware of the dangers of identity theft and you couldn't be too careful in a place like this.
In the basement of the Internet Cafe, another computer screen flared into life:
... Terminal 2 Activated ...
... Cloning Facility Online ...
... Cloning Process Initiated ...

I need to stop ordering books from Amazon starting from this Monday (I ordered one over the weekend). I've managed to sort most of them out today and limited them to three shelves. Top shelf - mostly used and want to read, middle shelf - read most of them and might want to read again, bottom shelf - reference only. Oh the sad life of a geek!
This was taken for a challenge over at DPChallenge.com, it's another self portrait.
Strobist: Two bare Sb-80dx's, one behind me and above, the other underneath the desk pointed up at my face. Hardest part was restricting the light to not hit the wall just a couple feet behind me. I used some black tinfoil as a makeshift half snoot on the back light, and a yearbook as a gobo for the one under the desk.

Some of the guys from my office just love playing soccer during lunch-times in nearby Whitmore Square. I was doing papparazzi duty and shooting from behind a tree in the middle of their pitch. This way if the action got too close, I could get a measure of protection by ducking behind the tree trunk.

International Programmers Day
I am actually an hour or so early (my time zone) for this one but tis ok. On Jan 7 International Programmers Day will be recognized. I can't really see much from the web site other than the ability to send an ecard out to your favorite programemmer :). In any case now you know as much as I do about International Programmers Day.

Another job is to be a programmer. They write and develop the codes that make a video game work. www.ronyasoft.com/products/poster-forge/templates/funny-s...
Aah, a strong black coffee and a nice donut just what a programmer needs to get through another bug!
8K EEPROM on the left. Arduino pro micro as the programmer. 16 address lines provided by two 595s in the middle. A few control lines and 8 data lines direct from the Arduino. I'll only be writing a few bytes for now.
Xmas eve, soldering..:) This is a simple programmer for attiny2313, instructions is here: www.instructables.com/id/Ghetto-Programming:-Getting-star...
I'm starting to feel the inclination to get back into electronics hobbyism these days - and on the photography side that means closeup / macro shots will be coming along soon.
The fever hits me now and then to make some LEDs blink, and the way I generally do that is to write software for a microcontroller (MCU) - a tiny, cheap, single-chip computer - to do it.
Why bother? You might well ask. Well! MCUs form the heart of all sorts of nifty circuitry - anything that isn't actually a computer and yet is "computerized", which is pretty much everything, anymore. I plan to make fun simple things like clocks and little games and decorative blinky lights, but stuff like homemade MP3 players, GPS units, simple autonomous robots, and Web-based remote control devices are now well within the reach of hobbyist designers. All you have to do is get specialized circuitry to handle the GPS reception or MP3 decoding or time displaying, then plunk a MCU down to order it around according to directions specified by software you write.
These three circuits pictured are all "programmers", or interface devices that let you send MCU software from the PC where you wrote it to the actual MCU chip. These are all for the PIC family of chips manufactured by Microchip, Inc.
In the upper left, the venerable PIC-1a from 1996, a small-scale-commercial variant of a famous programmer invented in April 1994 by a hobbyist named David Tait. The "Tait Classic" circuit, as it came to be known, was intended only for one kind of PIC MCU, the surprisingly useful 16C84. It had space for a 1024-instruction program and 36 bytes of data RAM. Much, much more powerful MCUs are available these days for less than the old C84 cost, but it was a great little chip. The Tait programmer made hobbyist MCU programming affordable, I believe; until recently the professional-grade tools for it were very pricey by hobbyist terms. The Tait Classic could be built for a few dollars or ordered pre-assembled from a cottage industry sort of shop like I did for, IIRC, about $50.
In the upper right, a cottage-commercial version of the P16Pro40, which is basically a newer and more flexible version of the Tait Classic, able to handle several different chips. I think I got this one in about 2004.
These two both still work, as far as I know, but they connect to the PC through the parallel port - and modern PCs don't often have parallel ports! Certainly the little netbook I use now doesn't. Hence, my decision to buy the programmer in the bottom of the shot, the Pickit 3. It's a USB-based programmer made by Microchip itself, and it has several features the Tait-types don't - plus it's fairly cheap, as things like this now are (about $70 for the "deluxe" version of the Pickit 3).
Nifty, eh?
