HELP WITH LHFSD_HCK [HARDWARE COMPANION KIT]
During 2005-2009, Corollary Theorems LTD has sold a
good number of LHFSD-HCK kits throughout the World. If one owner of a LHFSD-HCK kit intends to sell it, just write to us, and we are going to
post your offer on this page.
Additionally, any reader who builds the LHFSD-HCK kit on a prototyping
breadboard, on a PCB, or on any other solid (and suitable) material could sell that (working) kit in our site. We will only advertise your offer,
on this page, without charging any fees. Therefore, any potential buyers are going to contact you directly.
A. OPTION "CTL_PCB_V22"
Corollary Theorems / Complement Control has a few PCBs left of the commercial version LHFSD_HCK V2.2. Note that this PCB version is perfectly compatible with edition 5 of LHFSD, and it includes only 2
(somewhat) "critical components": the analog potentiometer "POT", and the seven-segments display "3LED8". However, both parts are
standard, therefore it is easy to find the exact parts, or similar replacements. The rest of the parts are all standard
components built by many manufacturers.
The buyer is going to get the precise list of components used to build the commercial version, plus high resolution pictures
of the working kit. Consequently, it is easy to identify all components used on LHFSD_HCK_V2.2 commercial
version--all components can be bought
from DigiKey. In addition, there are adequate details in LHFSD book concerning
historical evolution of LHFSD-HCK kits--including the schematics used.
Commonly, we sell one CTL_PCB_V22 when the buyer purchases one softcover version of LHFSD (code LHFSD5), so that the S&H
charges cover both products.
PRICE [only one piece when sharing the S&H charges with one LHFSD5]: 3000
BUY LHFSD5 TODAY FOR ONLY 25 EURO!
STATUS: (barely) available
Again, once you build a working LHFSD_HCK kit, you could sell it to other readers. It is your product,
therefore you name its price and S&H terms. We only advertise your offer to other readers.
For example, suppose that you buy our product CTL_PCB_V22 (presented above). You finished working with it, and
you decide to recover some of the costs--just send us an email. We
will post your offer as a new Option, except you are the only one to manage the transaction--we insert only your email address, plus
any data you consider relevant.
In order to understand the overall functionality of hardware, firmware, software, it is sufficient that
you buy our book LHFSD5/LHFSD5-DW. However, if it is your intention to learn hardware, firmware, and software design
professionally, then you need LHFSD5/LHFSD5-DW book to guide your efforts in building the LHFSD_HCK kit, plus the package SC
ED5RV07EN_15 needed to make your kit work.
In addition, please note that the HFS design work is far from being cheap to deal with. In order to achieve your goals you need to be
really diligent, and you should have sound Project Management skills.
