Participate in our Weekend Brainstorm Discussion and you have chance to win Pioneer-FreedomBox-HSK!

Internet-of-Things-IoT-e1521969062826

This week we started the sales of Pioneer-FreedomBox-Home-Server-Kits, and got lot of exposure in the social networks. Immediately people start to send us ideas of how to improve and make the product even better.

This is the beauty of the Open Source – everything is open, everyone can check and review the sources and advice what and how can be done better.

Even regular users who has no great knowledge of Software and Hardware contribute with ideas and tips what they miss as features.

We are already thinking for design special hardware which to have four SATA interfaces and allow 2 or 4 HDDs to work in RAID, thus improving the data storage capacity and reliability.

Another direction we think is how to release lower cost version with only SD card, no battery UPS backup and slower Ethernet interface which to get closer to Mr. Moglen (FreedomBox Foundation founder) dream for $29 plug server.

Many people asked why FreedomBox software does not included private e-mail server, but only client. The major problem to implement it is how to keep such service clean, as spammers may compromise your ISP by infecting computers to send emails and your ISP IP addresses to be blacklisted, so you can loose your ability to send e-mails for reasons behind your control. We would love to hear your ideas about this.

We got interesting tip to add possibility two or more Pioneer-FreedomBox-HSK to work in-sync and backup/mirror the data, being physically separated by long distance. The idea is to keep your information safe even if one of the server is stolen, broken or bombed 🙂 This would be easy to do with rsync.

Our challenge for you this weekend is to provoke discussion about what would be useful new feature, which you want to see in Pioneer-FreedomBox-HSK software or  hardware improvement.

You can discuss here on our blog, in Twitter, Facebook or Mastodon.

One Pioneer-FreedomBox-HSK will be given away in Monday to random participant.

Have a nice weekend!

UPDATE-2019-04-30: sorry Monday was part Easter Holidays so we couldn’t update the recap for the Weekend Discussion, but here is summary of your feedback:

About the Software:

  1. Number of people requested PiHole to be included. What is PiHole? It’s DNS sinkhole that protects your devices from unwanted content, without installing any client-side software. It’s Network level ad and spyware blocker.
  2. Many requested  NextCloud to be add in FreedomBox. It duplicated some of the existing software in FreedomBox.
  3. Some requested home Git server to be included, but if you want to work on Open Source project hiding your code in private Home Git may be not best approach.
  4. LibreSSL as alternative to OpenSSL.
  5. Diaspora pod may be good but I have no idea how much resources it needs.
  6. WireGuard as alternative to OpenVPN.
  7. IPFS we admit we never hear before for it but it look cool.
  8. Snips  this looks like nice open source alternative to Alexa and Google assistant.
  9. Btrfs
  10. FreshRSS
  11. Matrix/Riot
  12. HomeAssistant not sure how this relates to FreedomBox targets for distributed Internet and Privacy, but well related to Home server.
  13. Bitwarden
  14. Federation i.e. two FreedomBoxes to may replicate/backup each others data without having access to each others data.
  15. Containerized services (not sure how fast will work virtualization on our current processor and memory).
  16. encrypted email server

About the Hardware:

  1. RAID.
  2. Kill switch to wipe encryption key.
  3. Low cost model just SD-card and Ethernet.
  4. Dual Ethernet.
  5. Option for more RAM.
  6. WiFi/Ble this may be a conflict with Debian as they do not allow binary blobs firmware.
  7. mSATA / M.2
  8. miniPCIe.
  9. USB 3.0.
  10. Microphone, Speaker.
  11. UFS cards support.
  12. solar panel power supply support.

Wow a lot to consider 🙂 Thanks for your incredible feedback!

We are back! Tg for PCB quiz answer

pcb-fabrication

Tg is the glass transition temperature of the PCB material and very important parameter.

At this temperature the raw PCB material changes from stiff glass-like material to a elastic and bendable plastic-like material.

The biggest problems in the PCBs during the assembly is the Z-axes thermal expansion as above Tg temperature PCB expands rapidly and if kept long time about Tg temperature the small PCB vias may/will crack internally.

The most evil part is that when the PCB cool off the vias will shrink and may still give unreliable contact like touching together two copper wires, but later with temperature changes, vibration moisture these internal cracks in the vias can cause lost of electrical connections on random basis.

Tg 135 was commonly used and good enough for the old SnPb technology.

Since 2006 the new Lead Free technology require higher soldering temperatures and Tg 135 is not good choice.

PCBs assembled by ROHS lead free technology should be done with material with Tg 170 to be reliable. Especially this is valid for multilayer PCBs with small vias less 0.4 mm.

Friday Free Board Quiz – the prize is AM3352-SOM-IND. What does PCB pagameter Tg means? How it affects the PCB assembly process?

AM3352-SOM-1

AM3352-SOM-IND is industrial grade TI Sitara Cortex-A8 module running at 1Ghz.

After our summer vacation industrial grade AM3352-SOM-IND module with 4Gb SLC NAND Flash and AM3359-SOM-IND modules with and without SLC NAND Flash will be in stock.

Quiz Answer- smallest unit in KiCAD

printed-circuit-board-design-124847_800x345

Smallest unit in KiCAD is 1 nm. This is (1/1 000 000)-th of millimeter.

Quite precise for PCB design!

For comparison the popular Eagle CAD base unit is 1 um which is 1000 times bigger, so KiCAD uses 1000 times more precise metrics than Eagle.

Actually lot of the modern chips today are made on 28-40 nm technology.

So maybe KiCAD designers when deciding to use 1 nm as smallest unit were thinking too expand KiCAD as ASIC mask generation tool in future?

…who knows 🙂

Random.org say our winner is @trebadur please send us your address to info@olimex.com to send your prize
