Just made my first SMD soldering

Today I made my first SMD soldering. This is where I started:

FT232RL and SSOP28 adapter

And this is what I ended up with:

Done!

Weather station project, Radio silence!

Here's a quick project update: I've been busy with studies, work and other stupid things and I haven't had much time to spend with really important stuff - my weather station project. Now that I finally got more time and spent couple of nights building I got radio silence! Oh ****!

Bob Lifts Bear - The Sequel

Especially for Gareth, who requested a sequel. It's all a bit silly, really, but fun making it. My Robonova has a new head, which I've managed to squeeze a servo, led board, and camera into. The camera isn't very good quality, but is an introduction for me in Object Recognition software. Also included is a simple bot using a Picaxe with 3 servos, 2 for driving and one for "Ted". It has all been done using simple delays and timing in both Robonova and "Ted's Truck". The "gun" is a modified ball point pen and party popper. The "bullet" is filed down plastic.

SI1120 Sensor

This is a new sensor I'm testing out.  Hopefully will be ready to go into the new sumo soon.

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

This is my latest FireFly codename Megan40 ...... because she sports 40MΩ feedback resistors

If you need detectors that are not affected by ambient light then i highly recommend using UltraViolet LEDs as detectors.

The detect circuitry is finished - next part is to shoehorn the picaxe 08 onto the back to control servo and UV glowtube.

Getting angry about the availability of electronic components in Europe?

Hi there,

it has been a while and I am still working on the stereoscopic vision issue for my small robot. Meanwhile I learnt, that the Parallax Propeller chip is by far to slow to handle and stream-edit an BT.656 conforming digital video stream, at least for what I have in mind. Therefore I am now working on a hardware-based video filter made of discrete components - a poor man's FPGA, so to say.

Of mice and men...

UPDATE: This project is now complete. Further details can be seen at GhostRoachMouseBullRam project page. You can still read below to see my adventures and problems encountered this project.

Zifduino bootloader programming shield

When I first began working with Arduino I was amazed by the incredible things people were doing with the devices. After a couple of successes with my little UNO R3 I wanted to make some things using  "standalone"  chips. Following some tips from fellow Ardweenies I discovered this: http://arduino.cc/en/Tutorial/ArduinoToBreadboard

Review: The Service Droid kit from Dagu

I have received my Service Droid kit along with the Rover 5 robot chassis on a Monday evening. Excited, I opened up the package to reveal 2 big boxes, one with the Rover 5 and the other with the actual SD kit. The base comes assembled, with a battery box, a screwdriver (with a magnetized Phillips end), an Allen key (hex wrench) and a little bag with silicone lubricant. The droid kit comes with lots of parts grouped in separate labeled bags for easier assembly. To do the assembly, I used a cutter, a plier and the screwdriver from the Rover 5 box.

Building a Herbie Style robot called "SCURBIE"

July 5, 2009

It took me a great deal of time to decide what my next project would be but finally after weeks or browsing this site I opted to doing yet another BEAM project before launching head first into the relams of programmable robots using such chips as the ardunio. I must admit thought it was kind of tempting to skip minor projects to launch a big one. ANyways enough of my rambling.

Sneak Preview of Navigate & Map (NaM) (XMOS)

Well, here's the early beginnings of my Xmos project.

A dead PS2 mouse, a micro servo, a Sharp GP2D12, and a WowWee Bugbot.

Yes, this is half (well, okay, slightly less than half) of the project. Figure I'll just build one to start off. Once I make it work then it's easier to build the second one.

Found the correct motors for Leo

Well found the correct motors for Leo, less than a $10 fix, actually $7.16 before S&H. Polulu.com wants another $10.95 for S&H.  I don't mind paying for S&H but would rather wait till I ordered more than the S&H is going to be.  I might get a few extra motors to put on the swap board and see what I can get for them.  $20 for 4 motors, or $30 for 15 motors, you do the math and see what you come up with.

Coil Gun Rifle

I have been making soem good progress on the Coil Gun Rifle:
