5 Making blogs that you must visit

In this post I will tell you about 5 making blogs that you must visit, I read them whenever they publish something new using my favorite RSS reader Feedly . The blogs vary from makers who describe their projects to blogs that surf the net and find good articles to share. If you know of other blogs that I may like, feel free to share!

KeerBot is getting ready for the Show – WOW !

As you probably remember from my previous posts (here and here) Keerbot is going to be presented in an art exhibition about open source. and here is the press release (Hebrew), I am quite happy that they offered us to show the project – I say us because most of the job is being done by Danny now – Android Application (Download link here).

KeerBot and cabin

The good news – Its alive ! It can move – up and down, left to right, which will be quite cool in the gallery, regarding art – there won’t be much – maybe some basic paintings, so you’ll have to stay tunes to the next versions of the app.

In the meanwhile you can have a look at the short video showing that it really work.

3 Quick steps to hall of fame (or shame)

Gallery HIT

HIT crew getting ready

Following my last post, there are some nice people who wants to put KeerBot in their gallery exhibition next week (HIT Holon, Israel), and I am very thankful and proud for that. BUT they want to make everything ready on time, the thing is that I don’t have anything (yet) ready and working, and since it’s not in my hands I can’t really give them a clear answer. This is part of the way open projects work, If someone feels like helping you so you might make it – but you can’t demand or pressurize since there’s no commitment, therefore I really don’t know if I can make it to the gallery with a working model (if so, WOW !!!)




My intention is the have the KeerBot App ready, which mean that you’ll have the Keerbot hanged on the wall at the gallery, and whoever downloads the app will be able to connect to it and draw some lines on the wall. surely amazing* !!                                               ( *might not happen… )  so stay tuned for updates.

Yes – there is a good platform, the mechanical and electronic assembly is good, all the parts are light and elegant packed on a laser cut piece of PVC:KeerBot IOIO OTG







it looks better then the last model’s:

KeerBot Initial model, 2 scrap stepper motors.

Constant pen pressure mechanism








I really hope to get the model working – but I intend to prepare a dummy model Just to be hanged at the exhibition.




Some other updates:

  • DannyR – A great guy is working very hard on the KeerBot IOIO App, In the meanwhile you can find his code at the KeerBot GitHub (which can be also accessed via tech/bits in the top site menu)
  • AlexK send me a really nice video of art and robotics (That I am always happy to share):

KeerBot is ART ?! come and visit in the HIT museum

KeerBot is on its way to be art – it is going to be presented in the research art gallery of the HIT (Holon Institute for Technology) in their Museum.

Few days ago I was contacted via my KeerBot Facebook page that some Masters degree art student that they found the project surfing the net, and want to present it in their “museum” (research gallery). It will require from us to finalize the android application and make this robot work. Stay tuned so you can be the among the first people to have the app and be able to visit and operate the keerbot live in Holon (HIT)

IOIO OTG micro controller activates KeerBot drawing robot

KeerBot has a new IOIO OTG brain ! replacing the Arduino with the new IOIO OTG  micro controller is slowly approaching, and the first step is right described right here in this post. KeerBot IOIO OTG

The future is here! The next generation of KeerBot projects is slowly coming… In the next generation the good old Arduino will be replaced by the more exotic IOIO OTG (If it’s the first time you hear of it – spend few moments reading about it here), and since the IOIO OTG speaks fluently with the smartphone (Android) through Bluetooth (BT) I say “Bye Bye” to the tons of wires that had to be carried by the KeerBot everywhere it went (4 wires for stepper X2, 3 wires for servo, 2 meters each…) Now all I need to make it work is 12V wire, and a smartphone. Cool ! ain’t it ?!

Instead of diving into the image trying to get thIOIO OTG_02e hardware I used,Inventory:

  • IOIO OTG by SeeedStudio
  • BT Dongle by DealExtreame
  • 2 stepper driver a4988 by Pulolo
  • 2 Steppers
  • 12V Power supply
  • Chassis,bolts, nuts,wires – improvise (will publish when final)

Few important notes: in the last few weeks I am getting help from a brilliant and super cool guy named D#@$ , he is a software engineer and that means that the Android Keerbot Application (yeah – #$@ application) will be available soon, so stay tuned.

I also want to thank Ytai for his great job creating the IOIO –Ytai’s blog

Robotic arm that records and plays movement

This is my latest project “Robotic arm that records and plays movement”, I took an IKEA Terial lamp and hacked it into a fully functional, motion recording, robotic arm. IKEA Tertial robotic arm KeerBot

This project answers to a need I had: a Third hand that holds a camera while I perform a test and takes photos/videos (useful when you’re stuck at the lab late at night, and suddenly need a photographer).
The downside to a robotic arm was obvious – It needs to be programmed, and it is the last thing you want to do when you need to make a video. So I made it motion capturing device as well…

You can see the full step by step guide at Instructables, enjoy and share.

ArduinoDroid – Developing for Arduino with Android

Finally – An application that enables youArduinoDroid logo to develop and edit Arduino applications directly from your Android! requires only a cable and that’s it!



ArduinoDroid is a new application, free in the play store here, tat enables you to write and edit Arduino sketches from your Android device, anytime, everywhere. it supports wide range of Boards, and performs the compilation of the sketches on the android device, eliminating the need for a laptop/workstation during the debugging phase of the project.

Samsung Galaxy S2 and Arduino

If you are an Arduino developer – you must know that you need to have a computer with a cable to work on the sketches, while most of the time it is comfortable (since you have keyboard for coding, big screen for debugging, and a table to lay all the stuff that is connected to the Arduino).

When you finish the core development and head to the field test you need to twink the parameters, to change something etc’, the laptop (even if you have MacBook air ;) is quite a hassle… Here comes this app for your assistance: you can simply connect a common USB cable (USB B plut to OTG – like this), and start editing the code where ever you are, while editing the code on the smartphone might seem not practical, using a tablet may be a very good solution when working on a project that involves everything beyond your table. (I guess that the majority of the Arduino projects)

I wanted to support the app, maybe I will, but supporting through “in app purchase” seems problematic to me – what about paypal ? google play ?

3D scanning at home – Autodesk Recap

Today, i had the pleasure to go to Autodesk’s event, in the event I spoke to their R&D crew and heard of some new cool stuff they have – High quality 3D Scanning (Recap here) and ShapeShifter (here) that can generate really cool artistic 3D models and give you the file for printing.

Autodesk_Recapp_LogoAutodesk Recap – This service is the professional version of the 123D catch, while it is still free (heard the not for long), uploading pictures will generate 3D model quite fast and will let you download it for your use (OBJ/RCM file formats)

Autodesk ShapeShifter – Is an in browser model generator for 3D printing that enables fast generation of really cool models, that can be easily used later (Blender, Meshlab) Autodesk_Shaeshifter
