Video Blog Episode #17 - Programmable Clock Divider

Totally forgot to post this here!

In this episode we take a look at my brand new Arduino Uno controlling a programmable divide-by-N counter 74HC4059.

Video Blog Episode #16 - USB Isolator Layout

In this episode, we take a look at my KiCAD PCB layout for the OSHW USB Isolator project.

My experience hitting Hack a Day

On May 1, my post "GPIBUSB For Sale" as linked to on Hack a Day. I figured I would take some time to give everyone an idea as to how much traffic that generated.

In the first 24 hours, the blog received approximately 1100 views. This quickly tapered off the next few days (133 -> 90) and has been in the 20 to 50 views a day since.

Blog view statistics for the past 30 days. Note for 'today' it just rolled over.

Those views generated interest from 7 individuals, from which 8 adapters were sold. For not having a webstore, I'd say that's pretty good.

All together so far, I've sold 14 adapters. One of the last remaining assembled adapters is going towards a group at my University. Now to get assembling some more, and maybe send one to eevblog Dave!


Now what about the other aspects? It was generally well received all around. Only a few negative comments overall. Most of them consisted of people trying to give me real criticism but were unable to communicate it in any reasonable manner. The concerns boiled down to a few main points.

•  Lack of "proper" driver chips. This wont impact most users. The eventual next version will include these.
• Lack of SRQ (service request) support. The functionality is there in hardware, just has not been implemented in the firmware. This is on the slate for being added. Since the GPIBUSB features the tinybootloader upgrading to new firmware is simple.

I also got some real help when it comes to some of the implementation. I plan on putting into place some of the suggested changes once I get a chance to fiddle around with that. First I want to get the usb isolator up and going.

Video Blog Episode #15 - USB Isolator

In this episode I show the KiCAD schematic for my recently started USB Isolator project.

This is something I will eventually have made, so keep an eye out for this project!

Video Blog Episode #14 - Audio Based Trigger

In this episode I show off my first electronics project I made just over 1 year ago. The concept was to trigger a separate circuit (such as the shutter of a DSLR camera) using audio.
