What is the HahnTronix Web Page?
My name is Mark Hahn, and HahnTronix is the name of my company.
I mostly do consulting on embedded systems design. Embedded systems are those computers most people never notice until they stop working, like the microcontroller that makes your watch keep time, or the computer that routes your phone calls. I've designed and programmed embedded systems large and small.
I also make high powered LED headlights and tail lights for bicycling. This started as a hobby and has become a small side business for me. It's on hold at the moment. Due to the pretty gradual improvement in our economy, I've had to take employment quite a ways from home. Don't get me wrong, I'm glad things are getting better, I just wish some of it was closer to home. My commute doesn't leave me much time right now for light building. I hope to start working a few days a week from home soon, so maybe by the summer of 2012 I'll have time to build more lights.
Bike light products and other useful stuff:
Night riding rules - Some rules of the road for after dark riding and other random thoughts.
User Interface - All my lights use a common user interface. You can change the way your light works to suit your needs.
ECD400 - A small handlebar light that kicks out a respectable 400 lumens. It can run on a number of power sources including 8 AA batteries.
BFL2010 - A very bright handlebar light most useful mountain biking at night, but also handy commuting. Available in a several brightness levels ranging from 1200 to 2000 lumens.
BRL2010 - A very bright tail light. Selectable brightness levels make it useful for day or night commuting. Available in a brightness levels ranging from 350 to 450 lumens.
BHL2010 - A small lightweight helmet light. Available in a brightness levels ranging from 450 to 700 lumens.
Accessories - You can order just a light head from me or a whole system. This page lists some of the accessories available for my lights.
Battery Health - Information on the care and feeding of batteries.
Battery Sources - I sell batteries to use with my lights, but if you need extra capacity, or have some unusual requirements, you might want to check out these links to places I've bought batteries from.
DIY Batteries - Pictures and instructions on how to build your own battery packs.
Backup lights - Always carry a spare light along when riding after dark. This page has descriptions of some of my favorites and links to where to buy them.
How to Order - Pricing for my lights and how to get them.
History - How I got into the DIY bikelight hobby.
Consulting services I offer:
Software design - I've written software for very small systems, like wristwatches. I've written software for mainframes. I've even written commercial PC applications. I have a lot of experience in diverse computer environments.
Circuit design - I usually design hardware that uses microcontrollers or microprocessors. I've done projects that just use discrete logic, and some using programmable logic. I also do analog design.
Printed circuit board layout - It's easier to solder your embedded system together if you have a PCB.
Prototype construction - After I've designed a circuit/system for you, I'll gladly build one (or several). Or I'll build one of your design if you want.
Test fixture design - I design and build custom test fixtures used for manufacturing electronic products.
