Current loop

current-loopWhat with the ICC Cricket World Cup over, Wellington’s Phoenix football team reaching the giddying heights of the top four, and the mould cleaned from the shower – it’s time for an Ohmart electronics cartoon: “Current Loop”.

Must have at least 4mA of clearance to ride this baby!

Also, I’ll see if I can push it out to Twitter. Here goes :-)

No, no, you can’t make me!

No, no, you can’t make me! So, I did it of my own volition. I joined Twitter. Why the heck not, right? If the Dalai Lama can do it, and I’m the sure the Queen has (or got someone to set it up for her), then I guess I can.

I’ll use it to publish new pix and cartoons as they fly off the paper.

So here’s the handle: @Ohmart_org

This puts me right up there with Carol Ohmart (B, C-grade actress) and Ohmart Orthodontics. I am truly humbled to be in such company of Twits. Er, people in the twittersphere.

Well, life goes on…

We didn’t win this time, but there are World Cups every four years. At least*Sigh* we did better in this one than ever before. Still, me and four million other kiwis are a little blue… as per pic below. I drew him waving, inside he’s saying “GAA-A-A-H-HHHH!!!!”.

Right! Enough moping, back to work!

South Africa: phew! Australia: nervous!

New Zealand’s cricket team who, since time began, have had the average skillset of a demented sloth face Australia today in the ICC World Cup Final. This is indeed big news, given we scraped into said final by the width of a mosquito’s eyelash against a spirited South African side.

People deal with the tension of a huge game like this in many ways, including (but not limited to) drink, potato chips, floor-pacing, fried chicken with sides of coleslaw and nom-nom potato-and-gravy, and conveying useful coaching tips to the players by screaming at the television. I draw. Any pencil, pastel, or other drawing implement that isn’t bolted down is seized upon. Any piece of paper or card, any cereal no longer requiring its box, any random offspring of mine wandering by with a forehead – all fair game.

On that note, said the conductor, here are Aunt Melda, Standard Cat, and Small Fish – brought to you by Grant Elliott smashing the penultimate ball of the semi-final for six, sending New Zealand into the final, and decorating our lounge in a shower of pencils and crayons.

Good luck to the team in today’s final!

Sri Lanka batting fails miserably…

… so it’s a good excuse to grab some colours and, er, draw a whale fish bird (thing). Why not?!


Thoughts out to the Charlie crew involved in the Paris attacks.

This cartoon from David Pope, political cartoonist at the Canberra Times:


The prettiest map in the whole tweeting world

Tweet-tasticCheck out this map tracking over six billion tweets which have been sent out into the world.

Created by Mapbox’s Eric Fischer, the interactive display highlights the 6,341,973,478 geotagged tweets from the last three and a half years, and the shows where Twitter use is most concentrated in the world.

The highly detailed map can be zoomed out to encompass the entire globe or zoom right in to see where Tweets were sent from in your street.

Using open-source tools to manipulate the data, Fischer said only about nine per cent of the tweets collected are visible on the map to avoid duplicating locations.


Decoupled!Warning: this cartoon may send ripples around the electronics community… it does have the capacity to give engineers the jitters (groan). In this cartoon, Wally the Wall-wart is shocked to hear that his wife, Di Gital, feels she cannot function properly when Wally seems incapable of regulating his behaviour.  “It’s all very well when I don’t have much on,” she complains, “but as soon as I get busy, you sag and become quite unsteady!”

Ouch. Where’s Wally? Decoupled, that’s where.

Spring cleaning, and a Circus of Fire

Jeremy and the Circus of Fire

Even computers should be subjected to a good ol’ fashioned spring clean now and then – and mine just has, turning up this art + children’s novel I created about 400 years ago. Actually, it’s one in a series of five. Book one is on Amazon Kindle – looks to be either free or 77 pence – I haven’t got around yet to e-publishing the e-others in an e-reader e-format. E-yet.

It’s a reasonable read (but I’m biased, said the transistor) – fear not: Stephen King, Kathy Reichs et al – this little gem threatens not your mighty income streams.

Link to Jeremy and the Circus of Fire.

The gist (in less than 457 words, but grab a mug of tea anyway):

“Jeremy is a ten year old boy with a love for animals, which often lands him in trouble with his parents and teachers. A travelling circus comes to town, and Jeremy gets to appreciate both sides of keeping animals – what the public sees, and what can happen behind the scenes – these circus animals are under-fed, maltreated, and miserable. Each day after school he visits the animals to offer them encouragement, and a little food ‘borrowed’ from his mother’s freezer. Unknown to Jeremy, the circus people have a plan to get rid of the animals – permanently.

One day he shelters under the animal cages from a heavy rain storm, and some very unusual lightning strikes the cages. He discovers two incredible things: he can talk to some of the animals using his lightning-struck radio, and that each of the five animals in the circus can do amazing feats they couldn’t do before. For example, the tiger can change his colouring to match an object simply by placing a paw on it, and the polar bear can hypnotise people. His new friends (Charlie the baby polar bear, Ella the giraffe, Pengy the Emperor penguin, Raja the tiger, and Toot the toucan) tell him about how they were stolen from their home by the circus people. Jeremy and Annabel (his best friend) rescue the animals just as the circus is burned to the ground by the unscrupulous owners – who expect to claim a hefty insurance payout and retire for good. When the fire is investigated though, no trace of the animals is found. The circus people have one week to find the animals – or they’re in a lot of trouble!

Jeremy and Annabel are then faced with the task of finding out from where the animals originally came, and how to get them home. They discover that the animals were taken from a special kind of zoo in Canada, and then have to deal with problem after problem in reaching their goal – everything from hiding the animals from their parents, to navigating the magical ‘Colour Corridors’, to trying to do the ‘responsible’, grown-up thing with children’s resources – all while juggling schoolwork and their trying teachers. Most of all, they must overcome the underhand tactics of the circus villains, who will stop at nothing to retrieve ‘their’ animals to get the police and insurance company off their backs.

To help them, they enlist a few friends along the way – including hundreds of ducks, thousands of stick insects, and an albatross called Georgina. Everyone in the team – especially the animals with their various, newly-discovered abilities – has to draw on their skills and willpower if they are to succeed in their goal!”

Red and Green, minus the Blue

RG-minus-B-500_sThis news just in, not only has coffee, wine, milk, chocolate, cholesterol, (basically anything with a hint of fun or taste to it) been bagged at one time or another, science and the media are always looking for new downers. Presenting! Blue LED peaks. That’s right. A few weeks ago science was trumpeting the Blue LED in the Nobel Prizes, now the spotlight (blue, by the way) is on our little 430-ish nanometre friends for less pleasant reasons.

Blue LEDs are cute little blighters that put out blue light. Some folks are saying that maybe it’s a bit bright. Or not. Could be dangerous. Harmful. Deadly. Or not. Your mileage may vary. In a year or so, they’ll be saying Blue LED peaks are good for you, like I wish they’d do with coffee, wine, and chocolate.

Blue LEDs, by the way, are a key part of the Red/Green/Blue triumvirate that together can make a squawkillion (1 with 1,572 zeroes after it) colours. Very useful, in fact, for generating images on…oh, let’s see… TVs, smartphones, tablets. That sort of thing. Imagine a TV that could only make colours from red and green?

Right, I’ve made my stand for the day, and also an “R plus G minus B” cartoon for the people over at Here’s the link.

Go blue!


Black Cab – new album! Games of the XXI Olympiad

Note here, because one of my favourite groups has just released their 4th album, after about 4 years of ups, downs, and mishaps. Introducing Games of the XXI Olympiad, by Melbourne’s Black Cab. It’s O for Orsome! I recommend you buy it – no, I don’t get a commission, but I do like them enough to donate to the album’s creation via Pozible, in the process getting my name included on the CD cover as a thank-you gesture. That’s pretty nice, so thanks back to you Cab.

On ‘Games…': “This time it’s the 1976 Montreal Summer Olympic games, where systematically doped up East Germans scooped the medals and Australia went home without a gold. East German shot put gold medallist Andreas Krieger was so steroid enhanced she became a he in 1997. Black Cab like a good story with both winners and losers.” (
