Project #2 – Lens – LED – Mk1
Project #1 – The AcceleroSynth – Mk1
Apr 3, 2012 @ 15:03
We are finally ready for our first electronics project, The AcceleroSynth. It is an microcontroller-based (Arduino) music synth that is controller by a 3 axis analog accelerometer. It will be both a hardware and a software synth. This is the announcement for the project and in the coming days I will post the BOM (Bill of Material), schematics and Arduino code with the first assembly video. The project will first be assembled on a protoboard, then a soldered version will be built either on a perfboard or on an Arduino ProtoShield. If there is enough demand either a PCB or an Arduino Shield will be built for the project and sold here. More on that later. The first installment on the building of the project should be up on a few days.

A Video Introduction to Microcontrollers
Tomorrow’s Video – An Introduction to Microcontrollers
Mar 28, 2012 @ 22:12
I’m hard at work… Actually make that “I think” that tomorrow’s video post will be an introduction to microcontrollers. I will dig some stuff out of the drawers tomorrow and as usual make it up as I go and it will probably be about microcontrollers.
Sleep tight…

Welcome to The Alpha Geek Blog
New Format and Name
Mar 14, 2012 @ 23:39
This blog was launched close to 2 years ago and was active only a few weeks. Our work load got the best of us and most of the blogs we maintained have been inactive since then. In the past weeks we have started to revamp our web presence and for this blog the first step was to change its focus and name. It was started as a consulting industry blog called “Consult Ants” and it will now become “The Alpha Geek” a video blog about all things technological. In the coming days the first video post will be live and we will also start posting project from programming of all kind (desktop, microcontroller, web and mobile) to electronics and even music instrument hacks.
Watch this space in the coming days for our debut video and further announcements.

Fun with browsers and WordPress
Apr 30, 2010 @ 20:40
It has been one of those days. Somebody reported to me last night that the theme of our <a href=”http://www.igourmand.com/eatdrink/”>food and wine blog</a> did not display the first photo of any page correctly. The first image appeared after a huge space. The problem only happened with Internet Explorer and everything was fine with Firefox. Thus became the quest early this morning at 8am and I started tracking the problem.
I first thought that it was some “Div” problem as the theme used was one that I had made over 5 years ago. I recently rewrote it to change the look and then I rewrote it again last week to bring it into line with the current WordPress theme architecture. I had yet to polish it and finish formatting it and commenting it properly, so my logical thought was it was just some error in one of the PHP files of the theme. I even remembered checking it with various browsers just last week to make sure there was not such a problem, but since I have been doing small incremental update maybe some little error slipped in and I did not catch it.
I first checked the source code in the browser to see if I could find something wrong there. I used a few automated HTML formatter and the results were dismal. If somebody has a good HTML formatter that actually works to recommend, please let me know.
I ended up formatting everything by hand and after reviewing the code found out that there was absolutely nothing obviously wrong with it, and nothing that would explain the discrepancy between Firefox and IE. I had a hunch that the problem might be with the sidebar code, so I disabled it and low and behold the huge space before the first image on a page disappeared. Thus my hunch was right.
I then re-enabled each section of the sidebar one after another until the problem reappeared and finally found that the problem was with the image links I added a few days ago in the sidebar. There is absolutely no reason that IE should behave this way, except that it does not interpret the CSS properly. There is plenty of space for both the sidebar image links and the image in the post, and even if I resized the image in the post to a smaller size the problem continued.
I then starting fine-tuning the CSS and with just a few minor changes of around 15 pixels in one section everything popped back together as it should. I guess that IE is just very bad at properly following the CSS and placing elements on the screen.
Once that was done I decided that since I was in the middle of doing a lot of things with the theme, I should finish it properly. I spent the rest of the day properly formatting the code, changing deprecated WordPress functions to their new versions, profusely commenting the theme so the next time I need to modify things I can quickly find what I am looking for, doing some minor cosmetic changes to the theme, and generally improved its function and look. I still want to spend a bit of time beautifying things, but now it will be a much simpler job after the work that was done today.
What started as what I thought would be a simple job finding a faulty line of code, ended up a day of detective work. The nice thing is that I learned a lot dissecting the more recent template format of WordPress as I had not digged in its depths since version 1.5. It is much more flexible and powerful now and I will go to bed much less stupid tonight after a great day learning new things about the inner works of WordPress. I’m just glad that the work was for myself as I would not have like to explain the reason to justify a full day a work simply to move a picture up in a blog to a client.

Looking for House in Mexico City
Apr 26, 2010 @ 21:03
We are actively looking for renting or buying a house in a good colonia of Mexico City. We have been renting classrooms and space for our various courses and conferences for a while and renting space for this in a good area of town gets very expensive very quickly. It prevents us from giving as many course as we wish, or making the courses as long as we wish. We also cannot cater to smaller classes like I prefer to do as we have to have a certain amount of people registered to justify the rental of a room for the course. Add to that that traveling time from where we currently live to most centric areas of town have increased from around an hour to from 2 to 3 hours each way 7 days a week, so even going to give the classes is getting more and more difficult and I do not see any real change except for getting worse.
We want to remedy the situation by either renting or buying a house in a good area of town and use part of the house to give our courses and conferences. This would solve the problem of being able to offer as many course as we want, being able to offer course for smaller groups, and definitively eliminate the traveling problem.
If anybody reading this post has something to offer us, or know of someone who might have something, please contact me directly as I am open to any suggestions.
