I have enough of the design work and validation done so I have ordered a set of prototype boards. Unfortunately, they won't arrive before the project funding period ends. However, I'm confident that I'm ready to test on a PCB with all the... (Read More)
Testing Update for Tiny Timer
August 20th - via: kickstarter.com
I'm excited to share some testing results. I had the opportunity last night to validate some design theory for the Max7221CNG chip and the 7 segment LED drivers. I also setup the rotary knob interface. The good news is that the driver chip and... (Read More)
LED and driver validated
August 19th - via: kickstarter.com
I'm excited to share that the LED display and driver IC were validated tonight. I did have a minor setback in that the interface didn't work quite the way I wanted with a rotary knob. I'm going to use a series of push and a run/program switch. ... (Read More)
Critical parts arrived for testing
August 19th - via: kickstarter.com
Over the weekend I received the sample parts for some testing. I ordered in a pair of LED chips, the IC to drive them, and some potentiometers for validation. A quick picture is attached below. We have 9 days left to fund. Please spread the... (Read More)

Are you interested in a basic kit without the LED readouts?
August 7th - via: kickstarter.com
I'd like some feedback from backers and watchers. Do you want an inexpensive device that is only programmable via Arduino? or a device with knobs and LED readouts? When I originally developed this project it was the former. I think making it easy... (Read More)

August 6th - via: kickstarter.com
I have some exciting progress to share. I've arrived at a draft design of the project. This is still subject to change based on validation and modeling. The pictures below show a draft PCB layout and a draft schematic. I need to validate... (Read More)
Prototype test successful for ISP header
August 6th - via: kickstarter.com
Last week I had some frustrations with a USBTinyISP programmer. It had a 10 pin header on it that was not compatible with the condensed 6 pin header I'm using. I went out on eBay and found this unit for $11.99 http://tinyurl.com/mu44hn4. I... (Read More)
Circuit Design Progress
August 5th - via: kickstarter.com
It looks like the project will be based on an Atmega328, which is the full Arduino chip. The programming and display interface adds a significant amount of complexity to the project. I spent some time in the last few days dialing in the LED and... (Read More)

August 1st - via: kickstarter.com
For those watching this project, I am sharing the ups and downs of product development. Trust me when I say that every project has it's fair share of downs. :) I received a prototype board yesterday from OshPark. Had a chance to check it out... (Read More)
Project Update - and Prototype Update
July 31st - via: kickstarter.com
I updated the product comparison today. I realized that the kit price was wrong and it left out two really important features I added. The features are replacing the DIP switch with a rotary knob, and using an 4 digit LED readout to display the... (Read More)
