Ballbot skeleton

It's been quite some time since I last wrote something here, before the last post that is 🙂 so it's about time I do so!

It all started when I saw a post on Instructables about a Remote controlled basket ball robot. I immediately started to plan how I could make my own - who doesn't want a remote controlled ballbot!

Since I've got a lot of R/C parts laying around I figured it wouldn't be too expensive to gather the rest of the electronics needed, a DC motor and an ESC.
In the instructable the author used a 7" (17.8cm) hamster ball as the housing for his ballbot. 7" is quite small if you want to fit sensors and other fun stuff into the ball and really make it into a robot, not just a radio controlled ball. Continue reading

555 TARDIS v1.0 files

I finally made some schematics for the TARDIS! I also noticed some minor design flaws, mostly aesthetical but no show stoppers! Stay tuned for v2.0 😉
The Schematics are a little bit different than usual. I made them on the top layer PNG of the PCB so it will be easier to see where to put the components.

The TARDIS has arrived!

Yestarday I finally got my shipping from Seeed Studio! It's always satisfactory to hold and look at a PCB you've designed yourself.

My own time machine

As soon as I get time I will start to draw the schematics for as many circuit layouts as I can find for this PCB. I've estimated it to somewhere about 15-20 different circuits that will be possible to build on the PCB!

555 TARDIS

I'm really back in business! This is the second PCB design I've made in the last two weeks!

the Time Machine

I've had an idea for something like this for quite a while now, but a much simpler one.
Originally it was a three-in-one-design with a Monostable, Astable and a LED Dimmer circuit on the same PCB, with a code switch to select desired function.

Now it's more some kind of an experiment board for the 555 IC, about 15-20 different circuits are possible to make. Continue reading

fireCrow v2.0 remote control

Finally I've managed to complete the PCB design for the fireNest v2.0 remote control.
I've been stuck with it for awhile now, projects piled up and I lost the spark!
Today I ordered the PCB's, so now I'm back in business! 😉

fireNest v2.0 PCB design

You can see a sneak peak of the design below:

This is a plug-in card that turns the fireCrow v2.0 into a remote control, the card is designed for an aluminum box that takes a 160x100 mm PCB card.

volkswagen transpoter explosion

Sunday, late night, outside our workshop, Anders (Gothenburg Prop Makers) shot the final scene for KMFDM - Amnesia music video:

The great car explosion (it's Anders old VW Transporter) at the end of the video was made by David Peter at Thunder Effects.

Here you can see how it looked like from my point of view:

Special effect course 2009

More old material 🙂

supplementary training

2009 I attended a supplementary course in special effects at PYRO Smålands Krutbruk AB.

We learned how to blow up and flip a car using petrol charges and zinkit + flash powder loaded in a pyretechnic piston that was placed in the ground, partially covered with soil, under the car.
We also blew up a set house with 5g cordtex, flash cracker cal. 21, a pyrotechnic dirt canon, and a petrol charge. Continue reading
