Update 20 May 2019 - The price has increased from $10.95USD to $13.95USD for the Digirule due to me using a new manufacturer who is much more reliable than my old manufacturer, but this also brings with it additional costs. Also, I am sending each ruler out myself from Australia rather than directly from China, this also has import costs associated with it when the Digirules are sent to me.
Update 20 May 2018 - Please note that every single product page on Tindie contains download links for user manuals, sourcecode, bill of materials and so forth. I have received some negative comments in reviews that there is no user manual but there is! - Just click the link on the Digirule page :)
Update 04 May 2018 - Digirule2 Coming Soon! check out https://bradsprojects.com/digirule2/ for more details.
I’ve seen a number of PCB rulers out there however they weren't interactive. I wanted one with LED's and buttons that you could play with - so I made the DigiRule! – The DigiRule is a 15cm (6″) ruler which is marked in binary digits rather than decimal. It has a number of built in digital functions including:
Four bit binary up/down counter
The Digirule also features 8 extra hidden 'easter egg' modes:
It is powered by a single 3V CR2032 button battery and the brains of the unit is a PIC 18F43K20 microcontroller. The functions listed above are controlled by nine surface mount push buttons and has twenty three surface mount LED’s to show the status of the inputs and outputs.
The rear of the ruler contains logic gate and flip flop truth tables, a binary conversion chart, a few select SMD component footprints and some drill hole sizes.
Full details can be found on the Digirule page on my website including:
Shipping will be straight from my manufacturer in China by Singapore post and will occur on Wednesday and Saturday each week. For bulk orders I recommend EMS shipping or DHL. Singapore post is cheap however it can be slow depending on where you live. Sometimes taking up to a month to arrive for some people. The CR2032 coin cell battery which is required to power the Digirule is not included due to shipping restrictions on batteries.
If you have any questions or concerns about any of my products before or after purchase, please let me know and i'll do all I can to help.
